Hot-dip galvanized I-steel is also called hot-dip galvanized I-steel or hot-dip galvanized I-steel. It is to immerse the I-beam after derusting into molten zinc at about 500 ℃ to attach a zinc layer to the surface of the I-beam, thus achieving the purpose of anti-corrosion. It is suitable for strong corrosive environments such as various strong acids and alkali fogs.

Galvanized H-beam is a cross-sectional area distribution is more optimized, more reasonable than the economic section of high-efficiency profiles, because of its section and the English letter "H" the same name. Since all parts of the H-beam are arranged at right angles, the H-beam has the advantages of strong bending resistance, simple construction, cost saving and light structure in all directions, and has been widely used.

I-beam is mainly divided into ordinary I-beam, light I-beam and low alloy light I-beam. Ordinary I-beam and light I-beam flanges are thick on the web plate and thin on the outside. Ordinary I-beam, light I-beam, because the cross-sectional dimensions are relatively high, narrow, so the section of the two main sleeve moment of inertia difference is large, which makes it in the scope of application has a great limitation. The use of I-beam shall be selected according to the requirements of the design drawings.

H-beam is a new type of steel for economic construction. H-beam has economical and reasonable cross-sectional shape, good mechanical properties, uniform extension of each point on the cross-section and small internal stress during rolling. Compared with ordinary I-beam, H-beam has the advantages of large cross-sectional modulus, light weight and metal saving, which can reduce the building structure by 30-40%. In addition, because its legs are parallel to the inner and outer sides and the leg ends are right angles, the welding and riveting work can be saved by 25%. It is often
