Please follow and adhere to the following advice:
- Strong impacts with heavy sharp objects (tools) should be avoided, as they can cause local damage, as well as cracks in the glass reinforcements. Do not pull heavy objects with sharp edges.
- Impacts can cause chipping and cracking on the outer surface of the grating. Composite gratings are designed in such a way that the reinforcement (fiberglass), which gives the gratings mechanical strength, is located deep inside the walls of the grating, in order to avoid possible weakening of the cross-section of the gratings in case of pinching. Small chips do not weaken the strength of the grating and it can continue to be used.
- After installation and during operation in an alkaline environment, white tarnish may appear on the surface of the gratings, it does not affect their strength.
- Periodic cleaning (grilles are basically maintenance-free) should be carried out with commercially available products and pressure washers – note do not use steam cleaners.
- Periodic inspection of fasteners should be carried out according to the grating environment. If damage is found, it should be replaced on an ongoing basis.
