Electrode holder rail steel

Galvanized steel section is widely used in steel structure building purlin,wall beam,can also be self-combined into lightweight roof truss,bracket and other building components.In addition,it can also be used for columns,beams and arms in mechanical light industry manufacturing.Galvanized steel,zinc layer uniform,smooth surface,strong adhesion,high size,all the surface is wrapped by zinc layer,the surface zinc content is usually in 120-275g/㎡,long service life corrosion resistance durable,is a kind of galvanized C-type steel high protective force.Galvanized steel section size adjustable,large compressive strength and other advantages.Although the section size of the steel formed by cold bending is light,it is in line with the stress characteristics of roof purlin,so that the mechanical efficiency of the steel can be fully utilized.A variety of fittings can be connected into different combinations,beautiful appearance,the use of steel purlin,can reduce the weight of the building roof,reduce the amount of steel used in engineering,so it is called economic steel,is the replacement of Angle steel,channel steel,steel pipe and other traditional steel purlin new building materials.
