Features of metal structures
Metal barbecues can be either stationary for a summer residence, or mobile or folding.
The first option is easier to assemble, as it only requires attaching legs concreted (or simply dug) into the ground. In this case, 2 supports submerged to a depth of 50-70 cm are sufficient. Mobile structures are installed on more stable supports in the form of a sled or 4 legs. The wheels are attached to the bottom of the supports. Sometimes they install all 4, less often - 2 wheels so that the grill does not move when any pressure is applied to the side.
A folding metal barbecue is a box for coals, the legs of which are either completely detachable or mounted on fixed supports. This design option is convenient for those who like to go out into nature, have picnics, and hikes.
How to make a grill on a stand with a cutting table
The roasting pan, installed on a movable stand with a cutting table, provides almost everything:
- the ability to prepare food, supply dishes, spices;
- conveniently, “at hand”, place accessories by hanging them on hooks;
- store fuel supplies and kitchen utensils;
- transport the kebab maker within the site.
In case of rain, the unused roasting pan can be turned upside down to prevent it from rusting and placed in the same location.
Grill drawing:
The technology for manufacturing the fryer is similar to the previous version:
- We cut out the body blanks from a sheet 4 mm thick.
- We weld the body.
- We weld handles from a 25x25 mm corner with a length of 100 mm.
The drawings schematically show the holes in the grill for air intake and the distance between them, as well as grooves for skewers. Why you don’t have to read them in the article “Ideal dimensions of a barbecue.”

Stand for barbecue: drawings with dimensions.
Making a frame from a 20x20 mm pipe:
- We cut the pipe to the dimensions specified in the drawing specifications, taking into account the angles of connection of the parts.
- We weld the three-dimensional frame frame. In the corners from the inside we strengthen the upper structure, grabbing it with 4 plates. We weld the handle. Install 2 wheels.
- We weld a cutting table from 4 pieces of pipe, and grab 4 plates from the inside at the corners. We weld 2 parts to it for attaching to the stand and hooks.
- We cut out the wooden parts of the tabletop and lower base.
- We assemble the structure:
- install the fryer,
- we install wooden elements.
Dimensions and typical diagrams
When making a barbecue yourself, you can focus on the following parameters and features of their calculation.
Width
Determined by the size of the skewers. The length of typical products is 45-50 cm, of which the useful or working length is only 30-35 cm.
Consequently, the maximum permissible width of a typical barbecue is 40 cm. Then the meat will occupy maximum space above the coals, and the heat will not be wasted.
Length
It must be calculated based on the average number of kebabs. The recommended distance between two skewers is 5-10 cm. For 6 skewers, it is better to make a grill 60 cm long.
For a large company, when meat is fried on 10 skewers at the same time, a meter-long grill is suitable. And for barbecue grills, a 40 cm long roasting pan is optimal.
Dutch oven depth
The ideal value is from 15 to 20 cm. For frying meat, a layer of coals 5-10 cm high is enough, and the recommended distance between the skewers and the fuel is 8 cm.
For wood-burning grills, the depth is increased, but then more coals will be required for good roasting.
Grill height
This parameter is selected individually for the chef. It is believed that the brazier should be at the level of a person’s waist, then it will be convenient to work with the barbecue.
Depending on the height of the cook, the height of the grill can vary from 80 to 120 cm.
Frypan wall thickness
For stationary barbecues, the rule works: the thicker the walls of the firebox (broiler) of the barbecue, the better. It is advisable to use metal sheets with a thickness of 5-10 mm. Such a grill will retain heat better and last longer.
If you want to weld a portable structure, sheets 3-4 mm thick are suitable. Then the structure will weigh less.

Advantages and disadvantages of a metal barbecue
Advantages:
- simplicity and a large number of design options;
- high assembly speed;
- possibility of self-production;
- relatively low cost when made by hand;
- high maintainability.
Flaws:
- The material is prone to corrosion, so it must be periodically tinted. At the same time, applying a protective coating to the outside of the coal box is useless; strong heat causes the protection to burn off;
- For manufacturing, you must have the appropriate skills and ability to work with tools.
Metal barbecues are popular and convenient; mobile models can be put away for the winter. However, the design itself is not very attractive; the box is covered with soot and does not decorate the area.
Beautiful barbecues with forged elements
Forged elements give the product originality, lightness and individual style. Even a simple cover or curled handle on a brazier makes it different from other kebab makers.
Forged elements are not only decorative, but also add strength to the structure. For advice from a master on how to properly weld a barbecue using ready-made forged elements, watch this dynamic 7-minute video:
How to make a barbecue without welding with your own hands, read the article “Dismountable barbecue”.
Instructions for self-production
Let's consider the process of assembling a barbecue made of metal. To make a simple model you need a minimum of materials and tools.
Tools and materials
Metal sheets 5 mm thick for the bottom and 3 mm for the walls
Steel pipes for making supports
Metal corner 20 mm for decorating the sides (you can also strengthen the connection between the bottom and the sides)
Grinder with cutting wheel
Welding inverter with a set of electrodes
Shovel or drill for making sockets for supports
Ruberoid, bitumen mastic for lining nests and applying a protective coating to supports
Protective paint for application on the grill
Expert opinion
Valery Garmash
Chef of the Grill House restaurant, griller
As a rule, heat-resistant black paint is used for painting so that the burnt edges do not stand out and create a contrast with the main coating.
Step-by-step instruction
We will show you how to assemble a simple grill yourself. Its design is so simple that any novice craftsman can make it.
For this purpose, a sheet of metal 2 mm thick was purchased from a metal warehouse. We recommend using metal with a thickness of at least 3 mm for the barbecue.
Since this grill (in our example) will not be used very often, 2 mm thick metal will be enough for us. Before starting work, for convenience, we made a small cutting diagram.
To obtain an even cut, you can use a regular iron strip as a guide bar.
When working, remember to use appropriate protective equipment.
Due to their design, homemade clamps are very helpful in work.
Once all the panels are cut, it's time to start drilling the holes. We decided to order a set of step drills for testing.
The optimal height of the grill sides is 150 mm. A row of holes is located at a height of 50 mm from the base. Hole pitch 60 mm. Diameter 12.4 mm.
The first impression of these drills is so far positive. The chips, as expected, come out of the hole in whole ribbons. I use a countersink to remove burrs.
We also place the recess for the skewers in increments of 60 mm.
It is best to process the sidewalls with a bag, pre-compressed with clamps.
When all the parts are ready, you can proceed to welding.
It is very convenient to use magnetic corners to secure parts.
We assemble the box using tacks.
Now you can scald.
It is not necessary to completely weld all the seams. We just wanted to practice welding one more time. We knock down the slag and clean the welds.
From 10 squares we make handles for easy carrying.
We will make the legs of the barbecue from 15 profile pipes, their length will be 80 cm. We trim the blanks using a cordless circular saw.
It will not be easy to get such an even cut with a regular grinder.
The legs will be attached using M6 bolts.
If necessary, this will allow you to store and transport the grill when folded.
To attach the legs, it is most convenient to use a wing nut.
When preparing barbecue, an additional work surface is never superfluous. A small shelf was quickly welded from 10 squares of reinforcement. It is installed in one movement in two sections of 15 professional pipes.
When all the work is completed, we clean all the parts and cover them with heat-resistant enamel. We wait for the paint to dry completely and you can assemble the grill.
The grill turned out to be very durable and quite stable. Its dimensions are as follows: height 80 cm, length 50 cm, width 30 cm, depth 15 cm.
When first ignited, the paint is fired within 15 minutes and it gains full mechanical strength.
The grill turned out to be very successful. Its design is so simple that even a novice welder can make such a grill.
Sometimes an awning or canopy is installed over the barbecue to protect the brazier from rain. The grill can also be painted with heat-resistant paint to protect against corrosion.
Characteristics of heat-resistant steel
In this block we suggest that you familiarize yourself with the characteristics of heat-resistant steel. It is from this that we propose to make a grill (third master class), because... structural integrity and resistance to deformation over time is the main task. The second point is to ensure that the steel rusts for as long as possible.
As suitable metals, we suggest considering the characteristics of 2 grades of heat-resistant steel: 09g2s, 15khsnd (nl-2). In addition to their heat-resistant qualities, they have a number of advantages:
- take a long time to rust;
- In stores you can buy thicknesses of 2mm, 3mm, 4mm, 6mm. In general, this thickness is enough to implement the project (15HSND (NL-2) only 6 mm or more). A metal thickness of 6mm is suitable if you want to make a solid stationary grill (it is heavy);
- Excellent for cutting and cooking.
09G2S - interpretation and properties of steel
09GS2 is a low-alloy structural steel with an increased endurance limit. This brand is widely used for welding steel structures, including suitable for barbecues. Use this grade of steel if you want to make a portable one.
09G2S
On sale you can find sheets with a thickness of 2 mm, which is ideal for portable grills and barbecues. However, nothing prevents you from making a stationary barbecue from steel grade 09G2S. For a more detailed understanding of the heating properties, we suggest studying the table below.
Pace. tests, °C | σ0.2 (MPa) | σB (MPa) | δ5 (%) | Ψ (%) |
20 | 300 | 460 | 31 | 63 |
300 | 220 | 420 | 25 | 56 |
475 | 180 | 360 | 34 | 67 |
Decoding of steel 09G2S is carried out as follows:
- 09-0.9% carbon component;
- G- Contains manganese;
- 2 – manganese 2%;
- C – silicon, less than 1%.
15HSND (NL-2) - interpretation and properties of steel
Steel 15HSND (nl-2) has excellent physical properties when exposed to high temperatures and is resistant to overheating. This quality allows it to be used when cooking thick-walled structures, including barbecues.
15HSND
This steel is more suitable for stationary structures than for portable ones, due to its thickness - at least 6 mm. How 15HSND (NL-2) behaves at elevated temperatures can be seen in the table
Pace. tests, °C | σ0.2 (MPa) | σB (MPa) | δ10 (%) |
20 | 370 | 620 | 20 |
200 | 370 | 590 | 15 |
300 | 360 | 610 | 11 |
400 | 375 | 590 | 14 |
500 | 300 | 365 | 17 |
15HSND is deciphered as follows:
- 15 – 0.15% carbon
- X – Chrome 0.6-0.9%
- C – Silicon 0.4-0.7%
- N – Nickel 0.3-0.6%
- D – Copper 0.2-0.4%
If you have not yet decided which of these grades of steel should be purchased for making a metal barbecue, rely on the price in your city and the availability of steel for sale.

Adviсe
In addition to the usual calculations for making a barbecue, you can use the additional tips given below to design a real recreation area in your country house or home area.
- If the length of the barbecue is planned to be more than 100 cm, then in this case it is recommended to equip the structure with additional legs. This will give greater stability.
- The metal grill can also be equipped with wheels. This will allow you to easily change its location on the site if necessary.
- A canopy can be constructed over barbecues and fireplaces. In this case, you can cook barbecue even in bad weather. If you also equip benches, plant flowers and shrubs, then this place will become the real heart of the garden plot, where in the evenings you can just sit by the fire, listen to the birds singing, and look at the starry sky.
- The design of a conventional metal barbecue can be additionally equipped with places for storing firewood, skewers, water and pokers. This will add additional charm and some charm.
- Cast iron is considered the best material for making a barbecue. It is very strong, durable and holds heat well. This will save on coal. In addition, it can be additionally decorated with forged elements.
- When choosing the location of a barbecue or hearth, you must be guided primarily by safety rules and not place the structure near buildings (the distance should be more than three meters), next to flammable objects, under trees, near fences, fences, gazebos.
- A stone hearth is best made from natural elements. But in order to build it in compliance with all building codes, rules, standards and technologies, it is better to resort to the help of qualified mason builders.
- It is better to cover a metal barbecue made by yourself with fire-resistant paint. This will make its appearance more aesthetic and significantly extend its service life.
- It is better to make slits for skewers on a roasting pan at a distance of 5 to 8 cm. This distance will allow you to easily turn each of them over without touching the neighboring ones.
- Before using the barbecue for the first time, it must be calcined, that is, light a fire in it, in order to get rid of all the harmful substances accumulated during construction.
- Near the hearth you can equip a small reservoir, pond or alpine slide. This will allow you to create a complete ensemble of a suburban recreation area.
It should be noted that the correct grill should always be made according to generally accepted standards, which must be slightly adjusted to individual requirements.
In this case, the meat will be cooked immediately in sufficient quantity, will not burn or dry out regardless of the cooking tool, the fuel material will be used efficiently and economically, and the heat will not escape into the air.
In addition, there is currently a wide selection of building materials that will be suitable for its manufacture, be it metal, steel, cast iron, heat-resistant brick or natural stone.
When decorating a barbecue, you can implement any ideas and projects, be it a small mobile fireplace, a stationary brazier or even a brick oven in your garden. Subject to compliance with building standards and fire safety, the result will only please the eye.
A real corner for cooking and relaxing with family and friends will become a favorite place to eat and spend time, relax and recharge with positive energy.
Useful additions
If you really get down to business, you should take care of the compartment for preparing coals. It can also be used as a casserole oven. The modification is quite simple. The length of the grill increases by 30 centimeters. A 35 by 35 square with a height of 20 cm is welded from a metal strip. The resulting product is welded to the side of the firebox, where there are no ventilation holes. Now the unit will look like an inverted letter “G”. If desired, a square of the same size with a circle cut out inside for a cauldron is attached to the top of the cube.
It is not very difficult to modify a grill that is familiar to everyone into a barbecue. If you weld the same box (can be made of thinner metal) and attach it to stainless steel hinges, it will transform into a fashionable device. The ends of the cover are enlarged with a profile for joint density and reinforcement. The original design would be in the form of a pirate chest or a Gothic version.
Device device capabilities
Metal hotspots can be:
- stationary. A distinctive feature is its strong fixation to the ground; a reinforced concrete foundation is useful here. The design has significant dimensions, allowing, in addition to barbecue, to cook dishes in a cauldron on the grill, smoke fish and meat;
- collapsible. They are actively used both in garden plots and on picnics; they are very compact, making them ideal for transportation. A subtype of collapsible hearths are folding models, which are also light in weight and have modest dimensions;
- portable. Such roasters are relevant in the warm season; they have wheels or legs, thanks to which the structure can be moved alone.
Regardless of the chosen drawing, the structure will consist of a base (aka bottom), a lid, a frame, grates, legs, and sides. A folding or pull-out table will greatly facilitate operation; forged elements can be used for decoration.
Smokers 5 in 1
We present to your attention a multifunctional smoker grill, which combines 5 functions at once: grill, barbecue, hot and cold smoker, and cauldron. This smoker will be an excellent alternative to American grills and barbecues, allowing you to avoid overpaying. A unique product makes it possible to cook in 3 compartments at once, because the package includes a vertical hot-smoking chamber, a grill chamber and a horizontal cold-smoking chamber. For user convenience, there is a small shelf on the side of the middle grill chamber, and at the bottom there is a designated area for placing heavier items.
A smoker grill is a universal device that allows you to cook any type of meat, fish, seafood, sausages, vegetables and even cheese! With hot or cold smoking, you can smoke foods; and grill ribs, brisket, pork, chicken, hot dogs, steaks and hamburger patties.

The technological process of creating a barbecue using welding
Here it is important to decide what kind of structure you are planning - stationary or portable. The first can be installed in a specific place and for a long time. The second one can be transported without problems.
Typically, the use of welding equipment is necessary when producing a stationary version. Before the work process itself, be sure to watch the video tutorials and decide how you will decorate the future device.
The work algorithm here is as follows:
Stage 1. Initially create cuttings. Lines must be marked on metal sheets. The guideline in this process is a previously made or copied drawing.
Stage 2. All the main components of the intended design need to be cut out of the working material. The work proceeds in accordance with the existing markings on the sheets. A bottom should form. This is the largest component. It is formed by four lateral parts. Two of them are short, and the other two are long.
Stage 3. Be sure to make holes in the long side components. They can simply be drilled in one line. They guarantee the penetration of oxygen into the firebox to the coals. And then the heat required for normal working process will be maintained in your device. The distance between the holes should be approximately 5.5 cm. Make sure that there is at least 2.5 cm left to the edge.
Folding options
The folding barbecue can have separate disassembled parts, or be completely modernized. Such designs are most often used on hikes. If the barbecue body model is not disassembled, its legs may separate. Collapsible barbecues are divided into portable suitcases and three-x versions.
Suitcases, briefcases, diplomats, cases, books
A camp grill in a suitcase is convenient to use due to its compact size and the ability to store all the parts together. Videos and photos of such products allow you to appreciate their merits. The only drawback of these products is the presence of mobile elements that gradually wear out.
Three X model
The ready-made folding grill three x got its name due to the supports shaped like the letter X. The main advantage of this design is its ease of use. All you need to do is open the grill to start using it. Such a camp stove has quite large dimensions and will not be easy to transport for everyone, but it can last a long time due to the minimum number of connecting elements.
Advanced version
A metal grill created independently can always be improved and supplemented with useful components. One of these is a canopy. Example:
In this design, both a table top and a frame for placing skewers will not hurt. The top of the roasting pan can be reinforced with a profile pipe. You need to cook it so that there is room for possible additions.
Example:
It is not necessary to cook a barbecue of this format. There are other design variations.
