Application

Designed for Class A balconies and terraces.

Description

Adjustable Class A fire rated pedestal and aluminium rail joist system that includes integrated clip and locking mechanism for fixing the Aluminium Box & I-beam Rails and MetalPad EX adjustable pedestal.


Features and benefits:

  • Rails and pedestal are Class A1 rated (EN 13501-1:2018) and fully compliant with BS 8579.
  • Specially profiled bearer rails/ joists click onto MetalPad EX pedestals.
  • Fully integrated substructure system for seamless connection.
  • Allows pedestals to be placed at larger centres whilst maintaining weight tolerance.
  • Joists “tie together” pedestals, giving more lateral strength to frame.
  • Fast and simple to install.
  • All fixings and connectors provided.
  • Wide range of designs and sizes available; height and shape variations easily created.
  • Single beam and profiled double box shapes available (15–100 mm high, 60 mm wide).
  • No rotting, warping or rusting.
  • Environmentally friendly, manufactured from recycled aluminium and fully recyclable.
  • Pedestal headpiece clips are installed on the headpiece of the pedestal.
  • Greatly enhances lateral stability.
  • Ultra-low height threshold for decking; 30 mm from the floor to the underside of the deck board.
  • Very high weight tolerance: 1560 kg, with a break point of 2057 kg.


Rail sizes:

Aluminium Box & I-beam rails:

  • 15 x 60 x 2000 mm box rail.
  • 20 x 60 x 2000 mm (2 mm thick) box rail.
  • 25 x 60 x 2500 mm (2 mm thick) box rail.
  • 50 x 60 x 2500 mm (3 mm thick) box rail.
  • 50 x 60 x 3600 mm (3 mm thick) I beam detail.
  • 75 x 60 x 3600 mm (3 mm thick) I beam detail.
  • 100 x 60 x 3600 mm (3 mm thick) I beam detail.
  • Alternative rail lengths available as non-standard products.
