Timber decking supports

دعامات الأرضيات الخشبية الخارجية (ديكنج)

Joist-carrying heads that take timber and composite decking on the same adjustable pedestal base.

Timber decking supports

A joist head turns the adjustable pedestal into a support for aluminium, timber or other joists, so the decking is fixed to the joists in the normal way while the pedestal takes up the fall of the slab. A rubber pad under the joist reduces footfall noise.

Across the pedestal range, supports adjust from 10 mm to 945 mm; the decking supports on this page cover 10–700 mm, with joist heads for timber, WPC and composite decking.
