H-beam is a kind of high efficient profile with economic cross-section which the distribution of cross-section area is more optimized and the ratio of strength to weight is more reasonable, and it is named because its cross-section is the same as the letter “H” in English. Since all parts of H-beam are arranged at right angles, H-beam has the advantages of strong bending resistance in all directions, simple construction, cost saving and light weight of structure, etc., and has been widely used.

It is mainly divided into two types: equilateral angle steel and unequal angle steel. Among them, unequal angle steel can be divided into two types: unequal sides and equal thickness and unequal sides and unequal thickness. The delivery length of angle steel is divided into two types: fixed length and double length. The selection range of fixed length for domestic angle steel has four ranges: 3~9m, 4~12m, 4~19m, and 6-19m according to the different specifications. The length of angle steel produced in Japan ranges from 6m to 15m.

Galvanized tubes, also known as galvanized steel tubes, are mainly divided into two types: hot-dip galvanizing and electro-galvanizing (cold-dip galvanizing). Hot-dip galvanizing is a process in which a steel pipe substrate undergoes a complex physical and chemical reaction with the molten plating solution to form a corrosion-resistant, tightly structured zinc-iron alloy layer with strong corrosion resistance. The commonly used specifications are +12.5~+102mm2. In contrast, the amount of galvanizing in electro-galvanizing (cold-dip galvanizing) is less, only 10-50g/m², and its corrosion resistance is much worse than that of hot-dip galvanized pipes.
