DETAILS

Angle steel, commonly known as angle iron, is perpendicular to each other on both sides of the vertical strip of steel. Equilateral angle and unequal angle of the points. The two sides of an equilateral angle are equal in width. Its specifications to the width of the edge × width × mm edge mm said. Such as "∟ 30 × 30 × 3", which means that the width of 30 mm, edge thickness of 3 mm equilateral angle steel. Also available models that the model is the width of the centimeter, such as ∟3 #. Model does not mean that the same model in the different side of the thickness of the size, so contracts and other documents will be angle steel edge width, edge thickness fill complete, to avoid using a separate model. Hot-rolled equilateral angle specifications for the 2 # -20 #. Angle according to the different needs of the structure composed of a variety of force components, but also for the connection between the components. Widely used in a variety of building structures and engineering structures, such as beams, bridges, transmission towers, lifting transport machinery, ships, industrial furnaces, reaction towers, container racks and warehouses.

In a variety of building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reaction towers, container racks, cable trench support, power piping, bus support installation, and warehouse shelves.
Angle is a carbon structural steel construction, is a simple cross-section of steel, mainly for metal components and plant frameworks. In use requires better solderability, plastic deformation properties and a certain degree of mechanical strength. The raw material billet for the production of angle steel is a low-carbon square billet, and the finished product angle is hot-rolled, normalized or hot-rolled.
