Hybrid aluminium pergola beams.

01About Span

Hybrid aluminium pergola beams.

Span is a tri-extruded hybrid beam — an aluminium core wrapped in a flexible adhesive layer and a low-maintenance bamboo composite outer. You get the long spans and structural confidence of aluminium with the warm timber look of composite, and easier installation at height thanks to the lightweight profile.

Use Span for pergolas, privacy screens, decorative architectural beams, cladding and soffits. The composite outer resists biodegradation, corrosion, insects and harsh weather, with built-in UV protection so it holds its colour year after year. Featured: the Savanna 150 × 50 mm beam.
