Galvanizing refers to the application of a layer of zinc to the surface of a metal

Carbon steel profile is an economical and efficient profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter “H”. Since all parts of “H” section are arranged at right angles, “H” section has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, etc., and has been widely used.
