Heavy Duty Grating is a pultruded bar type grating that can be designed and used like traditional metal grates. The solid individual bearing bars are designed to take heavy wheel traffic such as fork lifts, tow motors and truck traffic. Heavy duty grating is constructed of the same type composite used in the other products.
Three kinds of Heavy steel gratings, they are Plain Style Steel Grating, Serrated Style Steel Grating and I Bar Type Steel Grating. They are widely used in steel structure platforms, stair treads, sidewalks, drainages and well covers etc. We can design and manufacture standard steel grating and in customized shapes per client's requirements.
material: carbon steel or stainless steel.
cross bar pitches:24-200mm,of which 50mm,76mm and 100mm are recommended.
Steel grating is made by the world first-class equipment,which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance.cross bar is pressed into the bearing bar by high tension resistance weldingring which is controlled by computer.so we can produce high quality gratings with firm welding,smooth surface and high strength.
Surface process of gratings:
there are three types:hot-dipped galvanized ,
electro-galvanized and spraying brushing and soaking.anti-acid and alkali corrosion capacity the range PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property.
Finish treatments for Heavy Duty Steel Grating:
Hot dipped galvanized, cold dipped galvanized, spray painting,
dip anti-rust oil, can prevent oxidation.
Surface type:
Flat type, serrated type, I shape type(According to requirement made different protective treatment).
We offer the following products:
Heavy Duty Stainless Steel Grating
Heavy Duty Carbon Steel Welded Steel Grating
Structure Heavy Duty Grating
