Expansion:The dimension of equilateral angle iron is expressed by the width of the edge * the width of the side and the thickness of the millimeter. Such as: 30*30*3, which means that the width of the edge is 30mm, and the thickness of 3mm is equal to the angle of steel. Also available models (Tex) said that the model is the number of centimeters wide. The front angle types symbols "/" models, behind the upper right corner with the symbol "#", such as: / 30#. The specifications for equal angles are 2#-20#.
Unequal angle steel: in the field of engineering materials, relative to two equal side length equal angles, refers to the section of the right angle, L shaped, and unequal length of both sides of the angle. It is widely used in engineering structure, structure and variety of municipal public utilities, civil and military industries, such as industrial beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame, and warehouses, because the amount is less than the unilateral angle, so the relative price slightly higher.
Unequal angle steel is a cross section, such as the letter "L", with each side of each other vertically angled and of unequal width. Its specifications are expressed in long, wide, short, wide and * thick edges, such as "L30*20*3", i.e., unequal angles with long sides, wide 30mm, short width, 20mm, and 3mm of edge thickness. Can also use the model (number) said that the model represented by a fraction, molecular side length cm wide, the denominator for the short side number of centimeters wide, such as "L3/2#", said the 3 cm long side, short side said 2 centimeters. The specifications for unequal angles are 2.5/1.6#-20/12.5#.
