--- PRODUCT DESCRIPTION ---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.APPLICATIONS-flooring steel gratings -stair treads -sun
