Fiberglass grating is a composite material of fiberglass and resin, possessing characteristics such as corrosion resistance (pH 2-12 tolerance), high strength (tensile strength ≥200MPa), and lightweight (density 1.5-2.0g/cm³). It is suitable for applications such as chemical platforms and wastewater treatment. Routine maintenance requires attention to the following: 1. Surface Cleaning: Rinse with clean water weekly. Stubborn stains can be treated with a neutral detergent (pH 6-8). Avoid scratching with hard objects such as wire brushes. 2. Chemical Corrosion Prevention: Although resistant to acids and alkalis, it must be rinsed immediately after contact with strong acids (concentration >30%) or organic solvents. 3. Load Control: The load-bearing capacity of a single grating should be ≤3 tons/㎡. Avoid concentrating heavy objects on it. 4. Structural Inspection: Check bolt torque (standard value 20-30 N·m) and overall deformation (should be <2mm/m) monthly.
Fiberglass grating has low maintenance costs, but proper routine maintenance can further extend its service life and ensure safe use. Routine maintenance requires regular cleaning of the grating surface to remove debris, oil, and dust. Light stains can be rinsed with water, while heavy oil stains can be wiped with a neutral detergent. Strong acid or alkaline cleaners must not be used, as they may corrode the resin surface. Outdoor gratings should be regularly inspected for surface aging, checking for cracks, discoloration, powdering, etc., and taking timely protective measures.
Corrective repair techniques should be used for different degrees of damage. Minor scratches and wear can be repaired with resin repair agent. First, clean the damaged area, sand it smooth, apply the repair agent, and polish it after curing to restore the integrity of the grating surface. Localized cracks and damage can be repaired using the "cut-and-repair method." The damaged portion is removed, a patch of the same specifications is cut, and the patch is glued to the original grating with resin adhesive. Fiberglass cloth is then laid to enhance the strength. After curing, the load-bearing capacity of the repaired area is checked. Severely damaged or extensively aged gratings must be replaced immediately to avoid affecting safety. In addition, the condition of fasteners should be checked regularly, and rusty or loose bolts and clips should be replaced to ensure the grating is securely fixed.
