DIN 17100 ST44-2 I-beam

Date : 2016-10-14 15:19:37

Processing

Hot-rolled common ST44-2 I-beam:
Hot-rolled common ST44-2 I-beam steel, also known as transfection, and the cross-section of the strip-shaped steel. Its cross-sectional dimension to waist high (h) × waist thick (d), expressed as the number of millimeters. Ordinary hot-rolled ST44-2 I-beam manufacturers are Wuhan Iron and Steel, Anshan Iron and Steel, Baotou Steel and Pan zhi hua Iron and Steel.

Light ST44-2 I-beam introduction:
Compared with the normal ST44-2 I-beam, Hot-rolled light ST44-2 I-beam have higher waist, wider legs, thinner waist and legs,. In the load-bearing capacity to ensure that the conditions of light ST44-2 I-beam has better stability and conservation of metal when compared with ordinary ST44-2 I-beam, so there is better economic results.

The main purpose:
ST44-2 I-beam is mainly used for a variety of building structures, bridges, vehicles, brackets and machinery as well as factories, bridges and other large structures manufacturing and travel.
