1.Introduction of hot-dipped galvanized steel grating
1>material:carbon steel or stainless steel
2>cross bar pitches:maybe 24-200mm,of which 50mm,76mm and 100mm are recommended.
3>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.
4>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.

2.Specification of hot-dipped galvanized steel grating
1>. Steel grating Plane Flat Bar Specification:
Thickness:3mm,5mm are the common
(1)The shape of bearing bar: Plain type (may be omitted in the symbol of steel grating), Serrated type and I-Shape type
(2)Bearing bar pitches can be 12.5, 15, 20, 30, 30.16, 32.5, 34.3, 40, 60mm, of which 30mm & 40mmare recommended.
(3)Cross bar pitches can be 38, 50, 60,100mm, of which 50mm & 100mm are recommended.
Bearing bar pitch at 60mm
is especially for mining industrial production, the bearing bar pitch is 60mm, it solved the mineral splash in a hallway behind accumulation problems, often used in mineral mining and processing project . for more save material, is the best choice of condole top
Bearing bar pitch at 30mm
For the checker plate grating of the most commonly used models, the bearing bar pitch is 30mm. conform to the united states ,Australia , japan, and other countries. For this series of checker plate grating are the most dense and have the highest strength ,suitable for all kinds of application.
Bearing pitch at 40mm
For the checker plate grating of the most economic and light model, the bearing pitch is 40mm. accord with Britain, germany, france and japan standards specified fixed platform, aisle and stair step specification . often used in belt corridor ,warehouse shelves , the attic panel , shallow bridge ,guard railing ,sun shading etc
4.Tolerance of hot-dipped galvanized steel grating
The allowed deviation of length is +0/-5mm, while the allowed deviation of width is +/-5 mm.
The non-perpendicularity of bearing bar is allowed no more than 10% of width of bearing bar.
Cross bar surface should not surpass bearing bar surface 1mm, beginning & end of cross bar should not surpass the end surfaces of two sides of grating 2mm.
5.Standards of hot-dipped galvanized steel grating
|Steel grating standard||Steel standard||Galvanizing standard|
|China standard||YB/T 4001.1-2007||GB700-88||GB/T13912-2002|
6.The packing of hot-dipped galvanized steel grating
normally packed in pilling up ways with two pieces of square wood on both upperand bottom sides.there are four or six pieces of M10 long bolt penetrading the gratings and screwing together.it is suitable for loading and unloading by fork-lift and crane.
