Load rating: Must ensure the grating can support the expected loads (personnel, tools, possible occasional heavier loads). If underspecified, it may sag, break.
Deflection & Span: Distance between supports matters; thicker panels reduce deflection.
UV & Weather: Quality resin / UV stabilisers important. Cheaper FRP may degrade faster.
Fire resistance: Sometimes needed depending on regulations. Check flammability or fire retardant properties.
Slip safety: Surface finish and mesh size should ensure grip.
Installation accessories: Clamps, fasteners, supports; ensure compatible hardware is available.
