Angle steel ASTM Low-carbon Angle steel galvanized iron Angle steel
PRODUCT PRODUCTION PROCESS
The production process of angle steel usually includes the following steps:
Material preparation: Select steel plate materials that meet the requirements, usually hot-rolled or cold-rolled steel plates, and select materials according to design requirements and standards.
Cutting: Cut the steel plate according to the design requirements to obtain a steel plate blank that meets the length requirements.
Heating: Send the cut steel plate blank into the heating furnace for preheating treatment to improve the plasticity and processing performance of the material.
Cold bending forming: The preheated steel plate blank is sent to the cold bending forming machine for forming processing. Through processes such as rolling and bending, the steel plate is cold-bent into the cross-sectional shape of unequal angle steel.
Cutting to length: Cut the cold-formed unequal angle steel according to the design requirements to obtain unequal angle steel products that meet the length and size requirements.
Leveling and straightening: Level and straighten the cut unequal angle steel to ensure the straightness and dimensional accuracy of the product.
Surface treatment: Surface treatment of unequal angle steel, such as rust removal, painting, etc., to improve its anti-corrosion performance.
Inspection: Conduct quality inspection on the produced unequal angle steel, including inspection of appearance quality, dimensional deviation, etc.
Packaging and leaving the factory: Pack the qualified unequal angle steel, label the product information, and store it in the factory.
Product Detail
Equal and unequal carbon steel angle bars are common structural steel components used in construction, manufacturing, and engineering projects. Both types are L-shaped and made from carbon steel, but they differ in the dimensions of their legs.
- Equal angle bars have both legs of equal length, forming a 90-degree angle. They are used in applications where a right-angle structure is required, such as frames, supports, and reinforcements.
- Unequal angle bars have one leg longer than the other, resulting in a non-90-degree angle. They are suitable for applications where a varying support structure or specific load-bearing requirements exist.
Both types of angle bars are available in standard dimensions and are often utilized for framing, bracing, and support in various construction and industrial settings. They can be easily welded, machined, and customized to meet specific project needs. Additionally, their carbon steel composition provides strength and durability for structural applications.
