Steel strip
Hot-rolled steel strip belongs to the flat-rolled category and is a universal metal profile widely used in industry and construction. Long-rolled strip products are used as a blank for the production of metal products for various purposes (including hardware products), and as an independent material in the production of construction, installation and finishing works. Classification, size range, basic geometric parameters and maximum deviations for hot-rolled steel strip are established by assortment in accordance with GOST 103-2006, marking, packaging and logistics are carried out in accordance with GOST 7566-94.
Assortment according to GOST 103-2006, accuracy class and weight per linear meter
According to GOST 103-2006 (instead of GOST 103-76, which is inactive since June 13, 2009), hot-rolled steel strip is divided into categories:
1. According to rolling accuracy
: B - increased accuracy, B - normal, separately in width and thickness. Designation for strip with increased thickness rolling accuracy: BT1, BT2, BT3, designation for normal thickness rolling accuracy: VT1, VT2, VT3.
The width rolling accuracy is indicated in the same way: BSh1, BSh2, BSh3 (increased accuracy) and VSh1, VSh2, VSh3 (normal accuracy).
2. As intended
:
- general purpose band (GP);
- strip used for stamping nuts (GShG - hot stamping, KhGSh - cold stamping).
3. By sickle class:
- AC - crescent shape is no more than 0.2% of the length of the strip.
- BS - permissible sickling within the limits of up to 0.4%.
- BC - sickling up to 0.5%.
4. Length
: strip of measured length (MD), unmeasured (ND), multiple of measured length (CD), in rolls (RD).
5. According to maximum deviations in length
(only for strips of measured and multiple measured lengths): BD - group of increased accuracy and VD - group of normal accuracy.
GOST 103-2006 establishes the following size range of long rolled strip: strip width (b) from 10 to 200 mm, thickness (a) from 4 to 80 mm.

Weight of 1 meter strip
can be calculated independently using the formula:
M linear meter, kg=0.00785×a×b, where a and b are standard values for the width and thickness of the tape in millimeters.
Steel strip weight formula
Formula for calculating strip weight: m = ρ × a × t
- ρ – metal density, kg/m3;
- a – tape width, mm;
- t – tape thickness, mm.
Strip steel
- This is one of the common types of rolled metal with a transverse rectangular section and a low profile. The tape is widely used in all industries, construction and energy.
Example notation
When designating a steel strip, the following characteristics are taken into account:
- above the fractional line, thickness and width, rolling accuracy, purpose, crescent class, current assortment GOST 103-2006;
- under the fractional line is the steel grade, GOST, which regulates the specifications.
For example: hot-rolled steel strip 4 mm thick, 40 mm wide, standard rolling accuracy in width, thickness and length with a crescent tolerance of up to 0.2% from ST3kp according to OST14-2-208-87.

MMK will show its products at an exhibition in Tbilisi
MAGNITOGORSK, May 18, news agency UralPolit.Ru. Today, the 21st International Specialized Exhibition “Caucasus Build – 2016”, dedicated to construction, begins its work in the capital of Georgia. The Magnitogorsk Iron and Steel Works is taking part in the event, reports the MMK information department.
Severstal Distribution increased sales by 18%
In the first quarter of 2016, the group (distribution network of the Severstal Russian Steel division) increased sales volume to 350 thousand tons, which is 18% more than the corresponding period last year. In January-March of this year, 14% of the steel products of the Severstal Russian Steel division were sold through the distribution network.
Japan and South Korea, as well as China, are lowering export prices
Seoul. Europe and the United States, blaming China for flooding their markets with cheap steel, “forget” about their allies from Japan and South Korea, who are also actively lowering prices in an effort to maintain market share. As Reuters writes today, the underestimation of the world's second and third steel exporting countries only underscores the pressure that the steel industry faces around the world.
According to analysts surveyed by Reuters, Japanese and South Korean metallurgical companies offer their products abroad at a third cheaper than on the domestic market. Representatives of the companies refuse to publicly discuss pricing, but admit that they sell steel cheaper in order to compete with Chinese manufacturers.
Mechel will postpone restructuring until 2022
Zyuzin asked for help from minority shareholders
Mechel's main shareholder Igor Zyuzin (controls 67.42% of shares) announced a possible postponement of the start of restructuring of most of the company's debts from 2022 to 2022, also asking minority shareholders to support its terms.
According to him, the agreements already reached with the largest creditors provide that the repayment period of the loans will be shifted to 2022, and for most loans the start date of repayment may be postponed to 2022.
Weight of 1 meter strip 40x4
1 linear meter of strip with a cross section of 40x4 mm has an estimated weight of 1.256 kg. The term “design mass” means that it is determined by nominal (tabular) section dimensions, with an accepted steel density of 7.85 g/cm3 and is a reference value.
Rolling accuracy significantly affects the permissible dimensions of the strip section. For normal accuracy (VSh and VT), the cross-section at minus tolerances (-1.0 mm and -0.5 mm, respectively) is reduced by 14.5%. If the reference weight of a linear meter for a nominal section is 1.256 kg, then with maximum minus tolerances, without going beyond the requirements of GOST 103-2006, the weight of a 40x4 mm strip will be 1.074 kg per linear meter.
Application area

- The ease of deformation allows the strips to be used as a starting material when creating forged shaped parts of fences, gratings, fences, and gates.
- The possibility of galvanizing significantly increases the resistance of the steel strip to the formation of corrosive processes.
- The small thickness of the product is indispensable in the manufacture of various small parts and fasteners that are assembled using the threaded method or a welding machine.
You can purchase steel strips at building materials markets, metal stores, or from the manufacturer. Strip 25x4 its price directly depends on changes in the cost of sheet metal. Most often it is indicated per linear meter. On average, a 25x4 strip price per meter is 45 rubles.
Please note that OSMA Metalbase produces steel strips from steel sheets of any size. Our equipment allows you to cut a strip or cut a strip on plasma. In addition to the above services, we can offer galvanizing of the required strip.
What is a steel strip, its types
Steel strip, as a type of rolled metal product, has its own parameters prescribed in GOST standards. The main characteristics of the strip are a solid profile with a rectangular cross-section. This type of rolled metal is produced from steel of various grades, which became the basis for the classification:
- carbon structural steel – St 10, 20, 35, 454, 40x;
- ordinary carbon steel – St 0, 1, 2, 3;
- low-alloy and alloy steel - St 09g2, 09g2s, 09g2d, etc.;
- spring steel - St 60g, 60s2, 65, 65g, etc.
The most widely used is steel strip, manufactured in accordance with GOST 103-76 standards. Less common, but also in demand, are other types of steel strip:
- hot rolled springs,
- structural,
- broadband rental,
- galvanized strip,
- hot rolled from tool steel,
- strips made of special heat-resistant and corrosion-resistant steels for the production of steam turbines.
Within the framework of GOST 103-76, the strip width varies from 11 to 200 mm, thickness - from 4 to 60 mm. Depending on the length of the product, stripes are distinguished:
- measured length,
- of unmeasured length,
- multiple measured length.
There are some features of the production of hot-rolled steel strip, namely:
- for the production of strips from 3 to 10 meters long, predominantly low-alloy, phosphorus or carbon steel of medium quality is used;
- strips ranging from 2 to 6 meters are made from high quality carbon or alloy steel;
- the maximum length of the strip should not exceed 12 meters.
Depending on the rolling accuracy, there are two classes that must be marked:
- average accuracy – “B”,
- increased accuracy - “B”.
