01
The skin that spans
PVDF and PTFE membranes pre-stressed over slender steel and cable, covering vast clear spans with a fraction of the material — translucent by day, luminous by night.

- ETFE foil

Tensile Membrane Architecture · Protective Steel Systems
We span the impossible — then make the steel beneath it last a century.
Two materials, one obsession. A membrane that turns tension into shelter — and a coating that turns steel into something permanent.
02
The armour beneath
High zinc-content epoxy primers and full coating systems that protect structural steel cathodically — engineered to outlast the structures they hold up.

- Epoxy mastic
- PU topcoat

Harbour Pavilion
A 6,500 m² PVDF canopy stretched between four steel masts, sheltering an open transit concourse. The membrane glows at dusk; the steel beneath is sealed against the elements for decades.
