Type GF Grate-Fast™
A high strength floor fixing for securing rectangular open bar grating to the supporting steelwork without the need for on-site drilling or welding.
Overview
The Type GF Grate-Fast fixing eliminates the need for costly scaffolding or elevated floors as access to the underside of the flooring is not required. Installation is carried out quickly and safely from above, often by one person, significantly reducing costs. The malleable iron cast body along with the unique stepped clamping face, which locks under the steelwork, provides outstanding clamping force and a secure connection.
Features & Benefits
- Superior clamping force from the cast body.
- Lloyd’s Register Type Approval for resistance to shock and vibration.
- Pre-assembled fixing for quick and easy installation.
- Designed for pedestrian walkways only.
- Easy to remove for maintenance access.
