Forgeweld Carbon Steel Grating

Around the world … whether the United States, Europe, or the Far East …, the definitive international grating stadard.  Jig assembly and automatic resistance welding (forgewelding) creates structurally rigid grating, with load bearing bars and transverse bars fused under pressure.  There’s no need for the manual assembly, punching, threading and swaging previously used for South African grating.

GRATING WORLD now brings you FORGEWELD™ GW40™ resistance heated and fused CARBON STEEL GRATING with special 6mm and 8mm twisted transverse bars for improved skid resistance.  Serrated edge load bearing bars may be specified for especially slippery conditions.
With a doubt, FORGEWELD™ GW40™ CARBON STEEL GRATING offers the most economical solution for most environments.

Still not sure?  Ask us for a head-on physical demonstration of the two grating types.

Standard panels are :

1000mm x 2500mm                              1250mm x 2500mm
1000mm x 3000mm                              1250mm x 3000mm
1000mm x 5000mm                              1250mm x 5000mm
1000mm x 6000mm                              1250mm x 5000mm

Special sizes and customising are available on request.

Finishes include mill (standard), coated (painted or powder coated), bitumenised, and galvanised.

IMPORTANT NOTES

  1. U, kg/m2, maximum allowable unfactored uniformly distributed loading for that stated span
  2. C, kg/m, maximum allowable unfactored centre line load per metre
  3. Load/Span Tables based on elastic deflections of span/200 or 10mm, whichever the lesser when subjected to the specified unfactored load using Young’s modulus, 200×109 Pa
  4. For serrated grating reduce tabulated allowable loads by 10% and maximum span per load category by 3.5%
  5. All table loadings to be taken as nominal and should not be used as guaranteed values
  6. Appropriate safety factors must be applied by the designer
  7. Galvanising will increase stated mass per square metre by approximately 8 – 10%
  8. Banding will increase mass by approximately 6% depending on grating configuration
