Channel. Assortments, tables and sizes of all channels

Channel - hot-rolled shaped steel with a box-shaped U-shaped section intended for steel structures, as well as structures with welded and other connections. Channels are manufactured with lengths from 2 to 12 m, by agreement between the consumer and the manufacturer - lengths over 12 m. The weight of the channel varies from 4.79-61.5 kg per linear meter.

The geometric characteristics of the channel section are determined by its number, which corresponds to the height of the channel wall (in centimeters). The channel is used in:

  • Powerful rod structures Bridges
  • Long span trusses
  • Columns
  • Ties and roof purlins
  • Frames (automotive industry)
  • Supporting Consoles
  • Stairs
  • Temporary passages (bridges)
  • Ties in sheet piling
  • Ramps
  • The geometric characteristics of the channel section are determined by its number, which corresponds to the height of the channel wall (in centimeters). The range includes channels with and without sloped internal edges of the shelves. The slope of the internal edges of the shelves makes design difficult.

    The range also includes channels with parallel flange edges, the cross-section of which has the best design characteristics. Such channels are more constructive, since the parallel edges simplify bolting to the shelves.

    If it is impossible to use a channel in building structures, you can resort to replacing the channel with an I-beam, or go to another analogue of the profile.

    Channels are used in powerful rod structures (places, long-span trusses, etc.), as well as in columns, ties and roof purlins.
