Steel grating reference
40 mm Bearing-Bar Pitch Load Table
Reference values for plain press-welded grating across clear spans from 200 to 3000 mm.

Reading the table
Match the designation and clear span.
Each row identifies the bearing-bar section, cross-bar pitch and theoretical mass per square metre. U denotes uniformly distributed load in kN/m²; D denotes deflection in mm. The adjacent U and D rows show different cross-bar pitches and must not be treated as a certified load/deflection pair.
Engineering use
These figures are for preliminary comparison. Confirm the calculation or test basis, loading, steel grade, support, bearing direction, deflection limit and applicable standard before relying on a value.
