Common Queries

Frequently Asked Questions

Detailed technical and commercial answers from our composite product engineering team.

We recommend a minimum of 4 clips per standard panel (or 4-6 clips per square meter) to prevent shifting, uplift, and vibration noise.

M-clips hold the grating panel down directly to the structural support beam beneath. C-clips connect two adjacent panels side-by-side to prevent tripping hazards when walking over joints.

Yes. Our specialized G-clamps hook around the flange of the support steel beam, providing firm hold-down clamping without requiring drilling or welding on-site.
