carbon-steel-h-beam-sm400b have good atmospheric corrosion resistance. In some cases, appropriate precautions can be taken, and they can even be used without being coated in the atmosphere. The elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel and molybdenum. The excellent atmospheric corrosion resistance of some low-alloy high-strength steels has led to the formation of new concepts in the design of buildings, bridges and other structures, that is, these structures are constructed with appropriate exposed components of low-alloy high-strength steel.

carbon-steel-h-beam-sm400b is a kind of economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio.
Because all parts of H-Beam are arranged at right angles, H-Beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions.
