Double Building Materials is a Guangdong-based factory with 25+ years of B2B export experience, specializing in custom staircases, railing systems, and cabinetry, with complementary solutions for wardrobes, pergolas, doors & windows, shower rooms, and curtain walls. We partner with contractors, architects, developers, and property owners across the USA, Canada, Australia, and Europe — supporting commercial, multifamily, and high-end residential projects with shop drawings referenced to IRC, IBC, NBC (Canada), AS 1288, AS 1657, and NCC. Every order starts from your drawings: converted to shop-ready drawings before any steel is cut, trial-assembled before packing, and shipped in export-ready crates, so the system you receive matches the site you measured.

We sent DBM the drawings for a Sydney coastal home and had marked-up shop drawings back in ten days — they'd already caught two clash points between the floating-stair landing and the railing posts. Issues we'd normally only find on site.
We've installed three DBM staircases around Austin this year. Shop-welded sections show up bolt-ready, every piece labeled to the drawings — the crew doesn't lose half a day chasing missing parts. The packing alone tells you the factory cares.
For a 48-unit multifamily in Charlotte we ordered glass railings, vanities, and closets on one container. The drawing-first process let us lock specs across all 48 units before fabrication — no substitutions, no surprises at the dock.
We commissioned the spiral staircase and bar cabinetry for our villa in northern Italy. The team worked through three rounds of revisions with our designer without a hint of impatience — and the trial-assembly markings made install two days faster.
