Description

On a ratio of size and form beams are manufactured of different types:

• welded H-beams replacing steel rolled beams for their geometrical adjectives as per GOST 26020;

• welded H-beams replacing steel rolled beams for their geometrical adjectives as per SТО АСCHМ 20;

• welded H-beams with individual sizes of panels and caps of the beams in accordance with the application of the Customer and design documentation.

Application of welded beam in construction of buildings and facilities allows:

- to reduce the cost of the construction;

- to use more effectively strength properties of the cross-section in case of using beams with individual sizes of the cross-section;

- to increase the sizes of bridge over bays by means of using the beams of more complex cross-section in comparison with hot-rolled ones.

- to reduce waste materials by means of manufacturing the beam of required length;

- to reduce the weight of the construction up to 10% in comparison with hot-rolled ones by means of optimal selection of the solid cross section.
