d² Quickspan is a non-combustible, fire-rated aluminium decking system for balconies, terraces, and walkways, tested to BS EN 13501-1 A2-s1,d0 and A2fl-s1 in UKAS-accredited laboratories.

Its centre-fix design uses a hidden fixing channel to fasten boards directly to the substructure, creating a clean surface that minimises trip and slip risks. Because fixings are secured in the central channel there are no fiddly clips, which saves handling time and labour. Final planks can be fitted after the balcony is craned into place, making the system ideal for prefabrication and rapid installation.

d² Quickspan’s dual-skin profile delivers exceptional span strength of up to 1300 mm. This means fewer supports, faster installation, and lower substructure costs, all while using significantly less material to reduce weight, cost, and embodied carbon.

An integrated drainage channel within each board captures water and diverts it to outlets at the board ends, enabling a Positive-Drain system where required. The same board can also operate in Free-Drain mode, offering full flexibility for smaller balcony designs.

Backed by a 30-year warranty, 60-year structural life expectancy, and verified by our EPD as the lowest carbon balcony decking in the world based on publicly available comparative data, d² Quickspan is built for long-term, low-carbon performance.

The 30-year warranty covers material or manufacturing defects for peace of mind, whilst the product has a minimum life expectancy of 60-years.
