Angle steel has good load-bearing capacity and stability, and can withstand large tension and compression. Its high yield point and tensile strength make it perform well in heavy-load structures.

Channel steel is a long steel strip with a groove-shaped cross section. It is a carbon structural steel for construction and machinery. It is a steel section with a complex cross section. Its cross section shape is a groove. Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing, etc.

I-beam is also called steel beam (English name Universal Beam), which is a long steel bar with an I-shaped cross section. I-beams are divided into ordinary I-beams and light I-beams. It is a steel section with an I-shaped cross section.

H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a 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 the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structure weight, and has been widely used.

Galvanized seamless pipe is a steel pipe that has been hot-dip galvanized. It has the advantages of excellent corrosion resistance, strong pressure resistance, strong impact resistance, beautiful and durable, safe and reliable, and economical and efficient.
