Description

Flat Steel

Flat Steel refers to steel with width of 12-300mm, thickness of 3-60mm, rectangular section and slightly blunt edge. Flat steel can be finished steel, and can also be used as blank for welded pipe and thin slab for laminated rolling. Main uses: as a finished product, flat steel can be used to make hoop iron, tools and mechanical parts, and used as house frame structural parts and escalators in buildings.
The flat steel is rolled with negative deviation, but it is delivered according to the actual weight, and the utilization rate is 1-5% higher than that of the steel plate.
Flat steel can be produced according to the user's requirements, with fixed thickness, width and length, which reduces the cutting, saves the process, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and materials. The products have been used in steel structure manufacturing, machinery manufacturing, automobile industry, mining machinery, lifting machinery and other industrial materials.


Angle Steel

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. The raw billet for the production of  steel angles is low carbon square billet, and the finished  Angle steel is divided into hot rolled, normalized or hot rolled state. Angle steel can make up different stress components according to the different needs of the structure, as the connection between components. Widely used in a variety of building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouses.
