Angle steel, commonly known as Angle iron, is vertical to each other into the angular strip of steel. There are equilateral angles and unequal angles. The two sides of an equilateral Angle are equal in width. Its specifications are expressed in millimeters of side width × side width × side thickness. Such as "∟ 30 * 30 * 3", it indicates that the width of 30 mm, while equal Angle steel thickness is 3 mm. It can also be denoted by model number, which is the number of centimeters of side width, such as L3#

I-type steel is a widely used in steel structure of the construction of purlins, wall beams, can also be combined into lightweight roof truss, bracket and other building components, in addition, can also be used in mechanical light manufacturing columns, beams and arms. It is widely used in steel structure plant and steel structure engineering. It is a common construction steel. It is made by cold bending of hot coil plate. I-type steel has thin wall, light dead weight, excellent section performance and high strength. Compared with traditional channel steel, the same strength can save 30% of materials

H-type steel is a widely used in steel structure of the construction of purlins, wall beams, can also be combined into lightweight roof truss, bracket and other building components, in addition, can also be used in mechanical light manufacturing columns, beams and arms. It is widely used in steel structure plant and steel structure engineering. It is a common construction steel. It is made by cold bending of hot coil plate. H-type steel has thin wall, light dead weight, excellent section performance and high strength. Compared with traditional channel steel, the same strength can save 30% of materials

C-type steel is a widely used in steel structure of the construction of purlins, wall beams, can also be combined into lightweight roof truss, bracket and other building components, in addition, can also be used in mechanical light manufacturing columns, beams and arms.
