Square and rectangular pipe is a name for square pipe and rectangular pipe, that is, steel pipes with equal and unequal side lengths. It is made of strip steel that has been processed and rolled. Generally, the strip is unpacked, flattened, coiled, welded to form a round tube, and then rolled into a square tube from the round tube and then cut to the required length.

Round steel is actually very common in life, but some people don't pay much attention to these. Round steel is actually a long strip of solid steel with rounded ends. Round bars are often used in the manufacture of large-scale manufacturers.

Rebar is a common name for hot-rolled ribbed steel bars. The grade of ordinary hot-rolled steel bar consists of HRB and the minimum yield point of the grade. H, R, and B are the first letters of the three words, Hotrolled, Ribbed, and Bars, respectively.

H-section steel is a kind of economic section of high efficiency with more optimized section area distribution and more reasonable strength-to-weight ratio. Because its section is the same as the English letter "H", it gets its name. Because each part of H-beam is arranged at right angles, h-beam has the advantages of strong bending resistance, simple construction, cost saving and light structure weight in all directions, and has been widely used.

Channel steel can be divided into 4 types shape: cold-formed equal-side channel steel, cold-formed unequal-side channel steel, cold-formed inner-coiled channel steel, and cold-formed outer-coiled channel steel.

Angle steel can form various stress components according to different structural needs, and can also be used as connectors between components.

Stainless steel strip is an alloy steel with smooth surface, high weldability, corrosion resistance, polishability, heat resistance, corrosion resistance and other characteristics.
