Profile steel is widely used in the manufacturing of various steel structures, such as large, medium, and small section steels such as angle, groove, round, and flat, as well as I-beams, channel steels, T-beams, window frame steels, automotive retaining rings, and wheel mesh steels.

Profile refers to shaped steel produced by hot rolling of steel, and there are many types of profiles. Mainly divided into:

1、 Angle steel: Angle steel, commonly known as angle iron, is divided into equilateral angle steel and unequal angle steel. Equilateral angle steel is formed by two sides of equal length perpendicular to each other, while unequal angle steel is formed by two sides of different lengths perpendicular to each other. Angle steel can be composed of various load-bearing components according to different structures, and can be used as connectors. It is widely used in various building structures, engineering structures, and mechanical structures.

2、 Channel steel: Channel steel is a long strip of steel with a groove shaped cross-section, belonging to carbon structural steel for construction and machinery. Channel steel is widely used in curtain wall engineering, machinery manufacturing, and vehicle manufacturing.

3、 I-beam: I-beam is a long strip of steel with an I-shaped cross-section. Due to its relatively high and narrow cross-sectional dimensions, the inertia moments of the two main axes of the cross-section differ greatly. Therefore, it can only be directly used for components that are bent in the plane of its web plate or to form lattice load-bearing components. I-beams are widely used in steel beams, buildings, and metal structures.

4、 C-shaped steel: C-shaped steel is automatically processed and formed by a C-shaped steel forming machine. The C-shaped steel forming machine can automatically complete the forming process of C-shaped steel according to the given size of C-shaped steel. C-shaped steel is widely used in purlins, wall beams, and can also be combined into lightweight building components such as roof trusses and brackets.

5、 T-shaped steel: Named after its cross-section being the same as the English letter T, T-shaped steel is divided into two types:

6、 Z-shaped steel: Z-shaped steel is a common cold-formed steel with a thickness generally between 1.5-3.0mm and a cross-sectional height mostly between 120-350. The processing material is hot-rolled and galvanized. Z-shaped steel is commonly used in large steel structure factories.
