L-shaped steel can be used not only for large ships, but also for marine engineering structures and building engineering structures with high requirements.

H-beam has a wide range of uses, mainly used in: various civil and industrial building structures; All kinds of long-span industrial workshops and modern high-rise buildings, especially in areas with frequent seismic activities and under high temperature conditions; Large bridges with large bearing capacity, good section stability and large span are required; Heavy equipment; Expressway; Ship skeleton; Mine support; Foundation treatment and dam engineering; All kinds of machine parts.

Classification and application characteristics of section steel

First, the application characteristics of angle steel

1, angle steel: commonly known as angle iron, it is a long strip steel with two perpendicular sides. There are equilateral angle steel and unequal angle steel. The width of both sides of equilateral angle steel is equal, and its specifications are expressed in millimeters of side width × side width × side thickness. For example, "∠30×30×3" is an equilateral angle steel with a side width of 30mm and a side thickness of 3mm.

2, widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, container racks, warehouse shelves, etc.

Second, the channel steel application characteristics

1. Channel steel is a long steel with grooves in its cross section. Its specification representation method, such as 120*53*5, means channel steel with waist height 120mm, leg width 53mm and waist thickness 5mm, or 12# channel steel.

2. Channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures, and it is often used with I-beams.

Three. Application characteristics of I-beam

1, I-beam, also known as steel beam, is a kind of strip steel with I-shaped cross section. Its specifications are expressed in millimeters of waist height (h)* leg width (b)* waist thickness (d), such as "I-beam 160*88*6", that is, I-beam with waist height 160mm, leg width of 88mm and waist thickness of 6mm.

2. I-beams are divided into ordinary I-beams and light I-beams. The specification of hot rolled common I-beams is 10-63#. The specification of the hot-rolled common I-beam supplied by both parties is 12-55#. I-beams are widely used in various building structures, bridges, vehicles, supports and machinery.

Four, cold-formed steel application characteristics

1. Cold-formed steel is the main material for manufacturing light steel structures, which is formed by cold-forming steel plates or steel strips. Its wall thickness can not only be made very thin, but also greatly simplifies the production process and improves the production efficiency. It can produce all kinds of profiles and cold-formed steel with uniform wall thickness but complex cross-section shape, which are difficult to produce by general hot rolling methods.

2. Cold-formed steel is not only used in various building structures, but also widely used in vehicle manufacturing and agricultural machinery manufacturing.
