Substructure
Non-Fire Rated Rail System
Suspension system for laying porcelain tiles, slabs & decking
Key Advantages
- Creates lateral stability across deck by reducing movement
- Complete substructure height, starting as low as 26mm and heights of over 1 metre.
- Bespoke headpiece clips onto profiled aluminium joist
- Aluminium rail clicks securely onto Mega Balance pedestals
- Timber or composite decking can also fix directly onto any Wallbarn aluminium rails.
- All components independently tested for weight tolerance and span capabilities.
Rail deflection - maximum span between pedestals
Rail height | Maximum distance between pedestals | Recommended maximum distance |
---|---|---|
15mm | 600mm | 500mm |
20mm | 800mm | 625mm |
25mm | 1000mm | 625mm |
50mm | 600mm | 600mm |
75mm | 1200mm | 1200mm |
100mm | 2200mm | 1800mm |

For Paving

An integrated rail system for installing porcelain tiles or paving slabs delivers enhanced support and lateral strength across the deck. The substructure securely links pedestals, bolstering surface stability. This modular system seamlessly pairs with any Wallbarn aluminum rails, including Box Rail & I-Plus Rail. These rails work seamlessly with our Mega Balance and Minipad pedestals.
The railโs headpiece features integrated lugs designed to secure porcelain or other slabs and tiles. The headpiece is adjustable, sliding along the rail to ensure a secure fit to tile edges. Available in 2mm or 4mm widths, all lugs are 10mm high.
This system is ideal for porcelain tiles and planks, supplied up to 1 meter in length. It not only enhances stability across the paved area but also speeds up installation. The lightweight pedestals and aluminum joists/rails are easy to handle.
Installation efficiency is improved as installers measure the pedestals at each rail end to attain the level.
Intermediate pedestals are then positioned under the rail and adjusted upwards until securely engaged.
