Custom railings for decks, stairs, porches, balconies and pool fences — one railing manufacturer for metal and glass, drawn to your project and shipped from Foshan.
Double Building (DBM) is a railing manufacturer in Foshan. We build custom metal railings and glass railing systems by the run: posts, infill and top rail drawn to your deck plan or stair, trial-assembled in our workshop and crated in labelled order. We work for owners, architects, builders and the railing contractors who fit them. Installation is by our own crews and partner installers in the USA, Australia and Canada (quoted separately) or by your local contractor.

Before you order custom railings
Can one project mix materials?
Yes. Glass on the main balcony with cable on the side terraces, or aluminum outside with wrought iron on the interior stair. Each material is drawn in the same package so corners, top rails and finishes line up.
Do you build custom metal railings to an architect’s drawing?
Yes. Send the architect’s elevation or detail; we turn it into shop drawings for your approval before fabrication.
What do you need for a quote?
The run length, a deck plan, stair photo or elevation, the finish you want, and the ship-to city. A phone photo with rough measurements is enough to start; we reply with shop drawings.
Do you sell by the run or by the piece?
By the run. Posts, infill and top rail are drawn and built for your deck, stair or balcony and ship together in one crate. We do not sell loose fittings.
Do you ship to the US?
Yes. We have shipped to 60+ countries. Every run is crated for ocean freight to your port, and freight terms are agreed with the quote.
Who fits it on site, and who signs off?
In the USA, Australia and Canada our own crews and partner installers can fit it nationwide, quoted separately, or your local contractor installs from the shop drawings and the assembly manual. A licensed engineer or certifier in your area signs off the drawings.
