The Angle
commonly known as angle iron, is perpendicular to each other on both sides into angular strip of steel. There are points of the of equilateral angle and unequal angle. Etc. width equal to the two sides of the equilateral angle. Its specifications to the edge width × width × edge thickness of a few millimeters. "∠ 30 × 30 × 3", i.e. which means the edge width of 3 mm to 30 mm edge thickness edge angle. Available model, the model is the edge width cm, such as ∠ 3 #. The model does not mean that the size of the same model in different edge thickness, angle steel and thus will be the contracts and other documents edge width, edge thickness dimensions completely filled in to avoid a separate model representation. Hot equilateral angle specifications 2 # -20 #. Purpose
angle according to the structure of the different needs of a variety of different force components, but also for the connections between the components. Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnace, reaction tower, container frame and warehouse shelves.

B / T 9788-1988; GB / T 9946-1988 implementation date :2009-04-01 issued by the department: China Iron and Steel Association Description: The standard integration amendments to the GB / T 706-1988 Hot-rolled I-beam size, shape, weight and allowable deviation, GB / T 707-1988 "hot rolled channel size, shape, weight and allowable deviation, GB / T 9787-1988 "hot-rolled equal angle size, shape, weight and allow deviation, GB / T 9788-1988 hot-rolled equilateral angle steel size, shape, weight and tolerances." GB / T 9946-1988 L hot-rolled steel, size, shape, weight and allowable deviation. " This standard replaces GB / T 706-1988 Hot-rolled I-beam size, shape, weight and allowable deviation, GB / T 707-1988 "hot rolled channel size, shape, weight and allowable deviation, GB / T 9787 -1988 hot-rolled equal angle size, shape, weight and allowable deviation, GB / T 9788-1988 Hot-rolled unequal leg angle steel size, shape, weight and allowable deviation ", GB / T 9946-1988" hot-rolled L-beam size, shape, weight and allowable deviation. " This standard specifies the hot-rolled beam, hot rolled channel steel, hot-rolled equal angle steel, hot-rolled unequal angle L-shaped steel and hot-rolled, size, shape, weight and tolerances, technical requirements, test methods, inspection rules , packaging, marking and quality certification. This standard applies to hot-rolled equal angle steel, hot-rolled unequal angle L hot-rolled steel and the inside of the leg the gradient hot-rolled I-beam and hot rolled channel. The standard GB / T 706-1988, GB / T 707-1988, GB / T 9787-1988, GB / T 9788-1988, GB / T 9946-1988 compared to the major changes are as follows: - increase the normative reference documents ; - an increase of some of the specifications; - Adjust the size, shape allowable deviation; - Increase the provisions of the technical requirements, test methods, inspection rules, packaging, marking, quality certificate
