What is Channel steel

Channel steel is a carbon structural steel for manufacturing and machinery. It is a section steel with a complex section, and its cross-sectional shape is groove-shaped. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing. In use, it is required to have good welding, riveting performance and comprehensive mechanical performance.

The raw material billet for producing channel steel is carbon-structured steel or low-alloy steel billet with a carbon content not exceeding 0.25%. The finished channel steel is delivered in the state of hot forming, normalizing or hot rolling. Its specification is indicated by waist height (h)*leg width (b)*waist thickness (d) in millimeters, such as 100*48*5.3, indicating that the waist height is 100 mm, the leg width is 48 mm, and the waist thickness is 5.3 mm. Steel, or 10# channel steel

For channels with the same waist height, if there are several different leg widths and waist thicknesses, a b c must be added to the right of the type to make a difference, such as 25#a 25#b 25#c, etc. Channel steel is divided into general channel steel and light channel steel Channel steel. The standard of hot-rolled general channel steel is 5-40#. The standard of hot-rolled flexible channel steel provided by the agreement between the supplier and the buyer is 6.5-30#. Channel steel is mainly used for building structures, vehicle manufacturing, other industrial structures and fixed cabinets, etc. , Channel steel is often used in conjunction with I-beam.

Features：

1. Light weight and high strength: only 1/4-1/5 of the weight of carbon steel, but the tensile degree exceeds that of carbon steel, and its strength can be compared with alloy steel. Therefore, it is widely used in products that need to reduce weight, such as aviation, rockets, high-pressure vessels, and auto parts.

2. Corrosion resistance: FRP profiles have good corrosion resistance, and are resistant to the corrosion of air, water, acids, alkalis, oils and solvents. In the anti-corrosion industry, FRP profiles have gradually replaced stainless steel. , metal, wood, etc.

3. Insulation: It has good insulation and is used in electric power, such as protecting cables, cable supports, etc.

4. Good thermal performance: heat insulation and flame insulation, it is an ideal material for heat protection and burn resistance, and can protect the aircraft from being scoured by high-speed airflow at 2000°C.

5. Anti-leakage: FRP pultruded profiles have high density and smooth inner walls, which can be used to transmit liquid media without leakage during transmission, reducing water quality and soil pollution caused by leakage.

Application

Stainless steel pipe is an economic profile of steel, which is an important product of the steel industry. It can be widely used in life decoration and industry. Many people in the market are used to making stair handrails, window guards, railings, furniture, etc. The common materials are 201 and 304.Widely used in furniture, petroleum, chemical, boiler gas, plumbing fixtures, aerospace, paper, automotive, food, packaging machinery, medical, decoration, furniture, railings, and other engineering, hardware processing, shipbuilding, power plants, and other industries.
