GRATELOK™ GL40™ CARBON STEEL GRATING is constructed by inserting round transverse bars through punched rectangular bearer bars, then swaging (pressure deforming) the transverse bars on each side of bearer bars. This produces a neat and rigid assembly with structural integrity. The range is designed in accordance with DIN, BS and NAAMM standards.
GRATELOK™ GL40™ CARBON STEEL GRATING is available with serrated load bearing bars for improved skid resistance in especially slippery conditions, or with non-serrated bearer bars for normal conditions.Bearer bars are 3mm and 4.5mm thick, with depths of 25mm, 30mm, 40mm, and 50mm. Heavy duty bearer bars of 6.00mm wide by 75mm or 100mm deep are available on request.
The standard bearer bar pitch of 43mm or 50mm provides effective spacing of 38.5mm (British Standard) or 45.5mm. Extended spacing of bearer bars and transverse bars are available on request, viz. GL40™ 43/100, GL40™ 86/50, GL40™ 50/100, GL40™ 100/50, and GL40™ 100/100.Standard panels are 2400mm by 1200mm. Special sizes and customizing are available on request.
Finishes include mill (standard), coated (painted or powder coated), bitumenised, and galvanized.
GRATELOK™ GL40™ CARBON STEEL GRATING offers and economic grating solution for most environments.

Suggested Range
IMPORTANT NOTES
- U, kg/m2, maximum allowable unfactored uniformly distributed loading for that stated span
- C, kg/m, maximum allowable unfactored centre line load per metre
- Loads determined by maximum deflection of span/200 or 10mm
- For serrated grating reduce tabulated allowable loads by 10% and maximum span per load category by 3.5%
- All table loadings to be taken as nominal and should not be used as guaranteed values
- Appropriate safety factors must be applied by the designer
- Galvanising will increase stated mass per square metre by approximately 8 – 10%
- Banding will increase mass by approximately 6% depending on grating
