Custom structural steel fabrication

Complex geometry.
Built with precision.

From BIM detailing to pipe bending, CNC profiling and full-scale pre-assembly, we turn demanding structural designs into installation-ready steelwork.

Integrated production

One partner from model
to finished assembly.

We combine digital detailing, purpose-built equipment and controlled workshop processes for long-span, curved and irregular steel structures.

01

Pipe Truss
Pre-assembly

1:1 workshop trial assembly using dedicated fixtures to control deformation, verify interfaces and reduce site rework.

02

Hot & Cold
Tube Bending

Controlled bending for curved and double-curved members, followed by dimensional correction and inspection.

03

CNC Pipe
Profiling

BIM data drives automated intersection cutting and bevel preparation for clean fit-up at complex multi-member nodes.

Quality assurance

Checked at every critical step.

Our inspection centre supports material verification, non-destructive testing and mechanical checks for traceable quality control.

  1. 01
    Incoming material

    Certificates, dimensions and material properties reviewed before production.

  2. 02
    In-process inspection

    Dedicated quality checks through cutting, bending, fit-up and welding.

  3. 03
    Critical weld testing

    Visual inspection and UT non-destructive testing for specified joints.

  4. 04
    Final dimensional review

    Assembly geometry verified against drawings before dispatch.
