Q345B steel I beam for building and construction

Steel H beam is a new type of economic construction steel. Economic and reasonable h-beam section shape, good mechanical performance, rolling section on each extension point is relatively uniform, small internal stress, compared with ordinary beams, with large section modulus, light weight, save metals etc.. mainlyused for large buildings that big cutting ability, good cross section stability (such as factories, high-rise building, etc.), and Bridges, ships, lifting transportation machinery, equipment foundation, support, foundation pile, etc

1. Steel material: Q235B, SS400, A36, ST37-2, S235JR, S275JR Q345B, etc.

Features and Advantages of H beam
A,If bear the same press, then the H Beam can save 10%-15% material.
B,You can have more designs of the rooms if you use H Beam than concrete.
C,H Beam is light than the concrete, so it is easy to carry and cut the cost.
D,The Building will be more stable, if it is built by H Beam, especially the places where earthquake usually happened.
E,The H Beam is environmentally friendly and reduce the Nuisance dusts.
F,The H Beam can save the real working time, because it is easy to carry and can be used in any weather. 

Applications of H beam
A, H Beams can be used in the industry and construction.
B, H Beams also can be used in the large Bridge.
C, The industries of trains, automobiles and tractors also will use the H Beam.
D, Frame Structure in marine and mechanical area.
