Angle commonly known as angle iron, is perpendicular to each other on both sides of a triangle strip steel. There equilateral angle and unequal angle of the points. Equilateral angle of the two sides are equal in width. Models do not represent different sides of the same thickness dimension models, contracts and other documents will thus angle of edge width, edge thickness dimension fill is complete, avoid using separate models representation. Hot-rolled edge angle specifications for the 2 # -20 #. Angle according to the different needs of different structures composed of members of the force, but also for connections between components. Uses: Widely used in various building structures and engineering structures such as beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reaction tower, container frame, cable channel bracket, power piping, bus bracket, and warehouse shelves. Angle is constructed of carbon steel, steel is a simple cross-section steel, divided into equal angle and unequal angle into two categories, which can be divided into unequal angle and varying thickness ranging equilateral equilateral Thick two kinds. Appearance quality: surface quality angle of the provisions in the standard, general requirements shall not exist in the use of harmful defects such as delamination, scarring, and cracks. Angle geometry of the allowable range in the standard deviation is also provided, generally comprises a curved, edge width, edge thickness, angle, other items of the theoretical weight and the predetermined angle of twist can not be significant.
