FRP Grating Inspection and Maintenance

Inspect the whole assembly

Check panels, supports, clips, edges, penetrations, joints and adjacent steelwork. Look for rocking, unusual deflection, loose fasteners, worn grit, exposed fibers, cracks, delamination, crushed areas, impact marks and unsealed field cuts.

• Compare with baseline photos or prior records.
• Map defects to panel marks.
• Record chemical spills, fire or hot-work exposure.
• Restrict access if damage may affect safe use.

Cleaning and surface care

Select cleaning methods compatible with the resin and anti-slip surface. Avoid assuming that a cleaner safe for steel or concrete is safe for FRP. Remove debris that blocks drainage or hides fasteners, then inspect the cleaned surface again.

Repair or replacement

Small surface work may be possible under a manufacturer-approved procedure. Damage to load-carrying bars, widespread delamination, heat damage, chemical attack or uncertain support conditions requires review by the product manufacturer or qualified engineer. Do not drill extra holes or add improvised clips as a repair.

Maintenance records

Keep the product designation, resin system, installation drawing, load data and manufacturer instructions with the asset record. These details are essential when replacement panels or repair materials are sourced years later.
