How every door is made

Every job goes through the same five steps in our factory, so you deal with one supplier and one schedule.

  1. WH

    Drawings

    We draw every job in CAD from your drawings, sketch or site measurements. You approve the drawing before we cut.

  2. Fibre laser cutter with cut steel blanks stacked on the loading table

    Laser cutting

    We laser cut frame and panel blanks from the approved drawing, with hinge, lock and strike preparations in the same pass.

  3. Two operators folding a long steel panel on a press brake

    Bending

    Our 3 press brakes fold frame profiles, panel skins and returns.

  4. Welder joining steel door frame profiles on a workbench

    Welding

    We MIG weld frame corners and assemblies, and TIG weld stainless steel.

  5. Steel door panels with lock boxes hung on a rack, ready for painting

    Painting

    We paint every door to your colour, then wrap it for delivery to your site in Malaysia or Singapore.
