Quality Inspection for Alloy Steel Coil - Equal angle steel Q195 Q235 SS400 A36 triangular hot galvanized angle steel – Lu

Introduction

Equal angle belongs to carbon structural steel for construction. It is a section steel with simple cross-section. It is mainly used for metal components and the frame of factory buildings. In use, it requires good weldability, plastic deformation performance and certain mechanical strength. The raw material billets for the production of angle steel are low-carbon square billets, and the finished angle steel is delivered in a hot-rolled, normalized or hot-rolled state.Angle steel is a long strip of steel whose two sides are perpendicular to each other and form an angle. There are Equal angle and unequal angles. The two sides of equilateral angles are equal in width. Its specifications are expressed in millimeters of side width×side width×side thickness. For example, “∟30×30×3″ means anEqual angle with a side width of 30 mm and a side thickness of 3 mm. It can also be expressed by model number, which is the number of centimeters of the side width, such as ∟3#. The model number does not indicate the dimensions of different side thicknesses in the same model. Therefore, fill in the side width and side thickness dimensions of the angle steel in the contract and other documents, and avoid using the model number alone.
