What we do

Seven trades, one shop

Everything we build →
Helical steel plate stair
S01

Feature stairs

Helical, curved and straight stairs in plate, channel and tube. Curved stringers are bump-formed on our own press brake, so the ribbon of steel is one continuous piece.

Curved stair with a steel picket guard
S02

Railings and guards

Rod, picket, flat bar, mesh and glass guards, with handrails that run clean through every turn.

Acoustic skin framing at National Sawdust
S03

Skins and cladding

Perforated and faceted metal skins, mesh scrims and cladding systems, framed, fitted and installed by us.

Black steel divided-light glass doors
S04

Doors, windows and storefronts

Thin-line steel doors and windows, storefronts and entries built to architectural tolerances.

Bronze-finish handrail return
S05

Polished and precious metals

Mirror-polished stainless, brass and bronze. The delicate work: seams you cannot find and finishes that hold up to hands.

Lit donor wall over a lobby stair
S06

Fixtures, signage and millwork

Retail fixtures, donor walls, counters, banquettes and paneling. Metal and wood under one roof.
