In the second-hand steel structure market, Angle steel is a kind of building materials, bearing capacity and adaptability can also be used as the connector between components. Strong adaptability and wide range of application, in beams, Bridges, power transmission towers, lifting transport machinery, ships and other aspects have been used.

From the metal structure of raw materials, Angle steel is a simple section of steel steel structure, common in life is the frame of metal components and plant. Good weldability, plastic deformation and mechanical strength are required in use. In the second-hand steel structure market, the raw material billet for Angle steel production is low carbon square billet, and the finished Angle steel is delivered in hot rolled forming, normalizing or hot rolled state.

Do not think the building materials that uses so extensively should be in specification face to face more optional. Angle steel specifications have strict requirements. Requirements shall not exist on the use of harmful defects, such as stratification, scarring, cracks, etc.

Angle steel in the actual product does not allow the deviation of Angle steel geometry, and even the curvature, side width, side thickness, apex Angle, theoretical weight and other aspects should be strict specifications. Such strict standards make Angle steel very popular in the second-hand steel structure market.
