[1000-Tianjin Steel Tube Co., Ltd - Products] component indexes angle or angle iron angle of the chemical composition of a general structural rolled steel series, the main test indicators for the C, Mn, P, S four. Depending on the grade, galvanized angle 100 * 50, the content differences, and galvanized angle 150 * 75, roughly in the range of C <0.22%, Mn: 0.30-0.65%, P <0.060%, S <0.060%. [1000-Tianjin Steel Tube Co., Ltd - Products] angle and angle iron is the same kind of steel, but it is called inconsistent. It is designed to make shelf steel, galvanized angle, there are a variety of shapes, many elongated hole punching easy for people to string screw is mainly used in shopping malls factory made shelf personal use. (It seems to do the same as windows and doors of aluminum profiles in order to facilitate people to do the shelf with) so called universal angle iron or steel omnipotent angle. Commonly known as angle iron angle angle iron angle, perpendicular to each other on both sides of a triangle strip steel. There are equilateral angle and unequal angle of the points. Equilateral angle of the two sides equal width. Its specifications indicated by the side edge width × width × edge thickness of a few millimeters. Such as "∠30 × 30 × 3", galvanized angle 125 * 75, it means that edge width of 30 mm, edge thickness of 3 mm equilateral angle. Models can also be said that the model is a few centimeters wide edge, as ∠3 #. 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 completely filled to avoid alone model representation. Hot-rolled edge angle specifications for the 2 # -20 #. Galvanized angle 150 * 90, galvanized angle steel, export processing provided by the Tianjin Steel Pipe Co., Ltd. Rong thousand. Galvanized angle 150 * 90, galvanized angle steel, export processing 1000-Tianjin Steel Pipe Co.
