Q235A H Beam structural steel for warehouse,building
Q235A H beam toughness and plasticity better, have a certain elongation, with good welding performance and hot workability. can be used to manufacture a variety of welded structural parts, bridges and some common machine parts such as bolts, rods, rivets, collars and connecting rods, etc., which are normally used in hot rolling. We are Q235A H beam producers in China, the following look at our Q235A H-beam mechanical properties and production processes.
