There are 3 core components of System 4: Junior Decking Board, Lite Joist & Adjustable Pedestal Brackets (see below).

Junior Decking Board

AliDeck Junior Decking Boards are specifically designed for installations on steel or concrete balconies, terrace decks, or walkway areas.

  • Boards can be cut to size along both the length and width.

Individual Boards:

  • Length: 4 & 6 metres

  • Width: 120mm

  • Depth: 20mm

  • Weight: 1.58KG per linear metre

  • Span: Up to 800mm

Junior Decking Board Benefits Include

  • FIRE RESISTANCE: The boards are manufactured completely from aluminium and are therefore fire resistant and non-combustible to A2-s1, d0 and A2fl-s1 when coated

  • DRAINAGE: They can also be spaced to allow for varying drainage requirements and are compatible with the AliDeck Balcony Drainage System
  • AESTHETICS: Aesthetics are key to a great finish; our boards are designed to look like decking but not to feel like aluminium
  • INSTALLATION: Speed and ease of installation are key to any project, so we have designed a board that has a unique invisible (structural) top clip system which can be installed from the top down. The board can also be trimmed down the length to match any projection of balcony and still be structurally stable across the whole plank.

  • SLIP RESISTANCE: See table below.

Pendulum Test Values (PTVs) – Low Slip Potential 35+ | Moderate Slip Potential 25-35 | High Slip Potential 0-25

  • Please Note: The test is conducted 8 times, with the first three tests being ‘warm up tests’ the data then starts to be recorded upon the 4th test. The average is taken from the 5 tests and is shown in the column marked MEAN. The directions are; Length, Width & Diagonal. Each direction has a score depending on wet and dry conditions. Direction A is length, direction B is width, and direction C is diagonal. The tests were carried out in accordance with BS7976 part 2. The full test report is available on our downloads page.
