Wharf Steel Grating:

High strength : the intensity and toughness far are higher than the cast iron, may use in the wharf , the air port and so on the great span and the heavy load environment.

Variety multitudinous: satisfies the different environment, the load , the span and the shape needs, may provide the size and the shape manufacture according to the customer.

We produce three kinds of steel gratings , they are plain style steel grating , serrated style steel grating and bar type steel grating , they are widely used in steel structure platforms , stair tread , sidewalk drainage and well cover etc. we can design and manufacture ,

Standard steel grating and in customized shapes per client’s requirements ,

(1) bearing bar (load bar ) specifications(mm) :the specification of plain type and serrated bearing bar is 20 *3 to 100*10 , the specification of section type is 25*5*3 , 32*5*3 , 40 *5*3. , 50*7*3, 55*7*4 , 60*7*4 ,65*7*4,70*7*4 ,75*7*4 ,etc.

(2) bearing bar pitch (centre to centre ) :12.5,15,25,30,30.16,32.5,34,40,41,41.25,45,50, 60, 60.32, 80 , 100mm, etc ,also be according to client’s requirements , and 30 , 40 , 60 mm are recommended , America standard is available ,

(3) cross bar pitch (center to centre ):38,50 , 76 ,100, 101.6mm,etc . , also according to clent’s requirements and 50 , 100mm, are recommended ,America standards is available .

Steel Grating Application

1) Galvanized steel grating from the flat width of 65mm-200mm thickness 5mm-20mm, such as welding formed galvanized steel grating for the post-heavy-duty galvanized steel grating suitable for large yard, docks, coal road bridges, etc., can carry large trucks pass.

2) Galvanized steel grating (Bearing Bar Spacing 40mm) spacing of 40mm steel hot dip galvanized steel grating is the most economical and lightweight varieties in the span of a smaller case, is the ideal choice.

3) Galvanized steel grating (Bearing Bar Spacing 60mm) flat steel bar spacing of 60mm to 50mm hot dip galvanized steel grating used in mining mineral mining industry to solve the problem of splash on the plate, often designated for mining processing plant

4) Galvanized steel grating (Bearing Bar Spacing 30mm) spacing of 30mm steel hot dip galvanized steel grating for the industry's most versatile breed in the common hot dip galvanized steel grating series, the impact on the surface the contact force of the strongest
