​Channel steel is a long strip of steel with a groove section. Channel steel is a carbon structural steel used in construction and machinery. It is a section steel of complex section, and its section shape is trough. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing. In use, it is required to have better welding, riveting and comprehensive mechanical properties.

Welded steel pipe, also known as welded pipe, is made of steel plate or strip after crimping forming welded steel pipe. Welded steel pipe production process is simple, high production efficiency, variety of specifications, less investment in equipment, but the general strength is lower than seamless steel pipe.

Galvanized corrugated guardrail refers to immersing rust-removed steel components in high-temperature molten zinc liquid to form a strong zinc layer on the surface to prevent corrosion and improve appearance. Galvanized spray guardrails first galvanize steel components and then spray a layer of plastic coating on the surface to achieve anti-corrosion, wear-resistant and beautiful effects.

It is a long strip of steel with an I-shaped cross section. I-beams are divided into ordinary I-beams and light I-beams. It is a section steel with an I-shaped cross-section. Whether the I-shaped steel is ordinary or light, because the cross-sectional size is relatively high and narrow, the moment of inertia of the two main axes of the cross-section is quite different, so it can only be directly used for members that are bent in the plane of its web or formed into a lattice-type force-bearing member.

Seamless steel pipe is a round, square and rectangular steel with a hollow section and no joints around it. Seamless steel pipes are made of steel ingots or solid tube blanks through perforation to make capillaries, which are then hot-rolled, cold-rolled or cold-drawn. The seamless steel pipe has a hollow section and is widely used as a pipeline for conveying fluid. Compared with solid steel such as round steel, the steel pipe has a lighter weight when the bending and torsional strength is the same.

Stainless steel plate is generally a general term for stainless steel plate and acid-resistant steel plate, which is an important metal material. The surface of the stainless steel plate is smooth, has high plasticity, toughness and mechanical strength, and is resistant to acid, alkaline gas, solution and other media corrosion.

Stainless Steel Coil is a thin steel plate supplied in coils, also called strip steel. There are imported and domestic products, divided into hot-rolled and cold-rolled. According to the needs of different users, we can also order a variety of special-shaped steel materials.In order to ensure that the yield strength, tensile strength, elongation and hardness of various stainless steel coils meet the requirements, the stainless steel coils must undergo heat treatment such as annealing, solution treatment, and aging treatment before delivery.

Angle steel,commonly known as angle iron ,is a carbon structural steel used in construction. It is a long strip of steel with two sides perpendicular to each other. It is a profile steel with simple section . Angle steel is divided into equal Angle steel and unequal Angle steel.

Round steel is a soli​d strip of steel with a circular section. Its specification is expressed in diameter, in millimeters (mm)
