Product Details

Galv welded grating floor, galvanized steel grid floor
 
 
 

Steel grating is welded 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

withfirm welding,smooth surface and high strength.

 

1.material: low carbon steel,mid steel or stainless steel

2.Surface Treatment: Untreated, Painting or Hot dip Galvanizing

3.Specification of steel grating

(1)The shape of bearing bar: Plain type (may be omitted in the symbol of steel grating), Serrated type and I-Shape type

4.Tolerance of hot dip 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. steel grating application

Steel grating used in flooring, catwalk, mezzanines/decking, stair tread, fencing, ramp, dock, trench cover, drainage pit

cover, maintenance platform,

pedestrian/crowded pedestrian, factory, workshop, motor rooms, trolley channel, heavy loading area, boiler equipment

and heavy equipment area, office buildings,

apartments, train stations, department stores, hospitals,amusement parks,etc

 

Stainless Steel Bar Grating

Stainless Bar Grating, is extremely strong, durable and corrosive resistant for all load bearing applications and is primarily used for pedestrian and light vehicle traffic. Welded stainless bar grating is available in a variety of bearing bar spacing and thicknesses depending on applications and load requirements. Available in either smooth top or serrated for slip resistance. See PDF specification sheet below for stainless bar grating load tables.
  • Specifications: 19S4 / 19SW4, 304 Stainless Steel
Custom Sizes and configurations are also available - Stair Treads, Trench Covers, etc.

Aluminum Bar Grating

Aluminum Bar Grating, also known as Swagged Aluminum Bar Grate it is light weight, yet strong and durable for all load bearing applications that need high corrosion resistance. Aluminum gratingis available in a variety of bearing bar spacing, thicknesses and heights depending on applications and load requirements.Available in either smooth top or serrated for added slip resistance. See PDF specification sheet below for aluminum bar grating load tables.
  • Specifications: 19SR4 / 19AS4, Alloy 6063-T6 for bearing bars per ASTM B-221, Alloy 6063 for cross bars per ASTM B-221
