Class A Rail System
Substructure for non-combustible decking and tiling systems
Key Advantages
- Full Metal Substructure, made from galvanised steel
- Class A non-combustible material (EN 13501-1:2018)
- Profiled Aluminium Joist clicks securely onto MetalPad
- Secure connection without mechanical fixings
- Suitable decking and paving solutions
- Very high weight tolerance
- Zero corrosion
- Creates lateral stability across deck by reducing movement
- Adjustable height with maximum flexibility
- Fully compliant with draft BS 8579
Specially profiled aluminium rails 20mm, 25mm or 50mm click onto headpiece without need for screws, drills or mechanical fixings for secure connection.
Powder coated headpiece prevents any reaction between steel and aluminium.
Paving / Tiling Applications
- Integrated Class A Rail system for installing porcelain tiles and ceramic planks
- Specially profiled bearer rails / joists click onto headpiece of Metalpad
- Designed to give greater support to slabs and tiles and additional lateral strength across the deck
- Faster installation of suspended paving and tiling projects
- Secure connection into spring loaded headpiece fittings; no screws, no drilling on site
- Large baseplates distribute weight efficiently reducing point loading
- Greater spans between pedestals possible
- Joist helps “tie together” pedestals, giving more lateral strength across the decking surface
- Large height range using three different sized joists
- Powder coated headpiece prevents reaction between steel and aluminium joist
- Additional headpiece clicks onto joist to hold slab / tile in place
- Clip head has four lugs for full support and uniform spacing of tile
- Clip head slides along Rail for accurate measurement and total support
- Fast, safe, secure construction of substructure
Decking Applications
- Fully integrated substructure system for installing Class A decking
- Specially profiled bearer rails / joists click onto headpiece of Metalpad
- Secure connection into spring loaded headpiece fittings; no screws, no drilling on site
- Large height range using three different sized joists
- Greater spans between pedestals possible
- Large baseplates distribute weight efficiently reducing point loading
- Powder coated headpiece prevents reaction between steel and aluminium joist
- Joist helps “tie together” pedestals, giving more lateral strength across the decking surface
- Class A decking surface fixed to joist
- Fast, safe, secure construction of substructure
