STEEL GRATING is made by the world first-class Italian ORSOGRIL 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 welding which is controlled by computer. So we can produce high quality grating with firm welding,smooth surface and high strength.
SURFACE PROCESS OF GRATING
HOT GALVANIZING
Normally,Hot galvanizing will be carried out after end welding process,For the thickness of bearing bars is not less than 5mm,the weight of average Zinc Layer will not be less than 610g/m2.When the thickness of bearing bars is less than 5mm,the weight of average Zinc Layer
Will not be less than 460g/m2. The quality and requirements after hot galvanizing are subject to the standards of GB/T 13912.
LACQUERING
To again protection layer through the ways of spraying,brushing and soaking.
SERVICE LIFE OF HOT GALVANIZING
Coated zinc thickness of 100um,the anticipated life of products in various circumstances.
ANTI-ACID AND ALKALI CORROSSION CAPACITY
The range of PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good
anti-corrosive property.
CALCULATION OF WEIGHT AND AREA
1.The weight of gratings varies after end welded and hot galvanizing process. For normal industrial platform using 30mm pitch bearing bars,the weight will increase 12%;14% for 40mm pitch bearing bars and 16% for 60mm pitch bearing bars.
2.For those gratings processed according to the size supplied by customer,calculation will based on the actual area(including cutout and tap)
3.For those gratings processed according to customer's drawing,calculation will be based on the
total outside size(including cutout and tap)
4.For unusual size of grating cutouts shall not deduct from the length and width.
