The process

From your drawing to a packed container

We are a make-to-print fabricator. The engineering stays with your consultant; what happens here is everything between the drawing and the shipment.

Laser cutting machine at the Huaining works
STEP 01

Cutting

Laser cutting, plasma cutting and CNC multi-torch flame cutting beds for heavy plate.

CNC multi-torch flame cutting bed
STEP 02

Profiling

CNC flame cutting, ganged torches for repeat parts straight from your drawings.

Submerged-arc welding line
STEP 03

Assembly & welding

Welding robots, submerged-arc welding and combined assembly-welding machines. Processes 135, 136 and 121, coordinated by an IWE-qualified engineer.

End milling machine for structural steel members
STEP 04

Milling & straightening

End milling and section straightening. This is where assembly-critical tolerance is won or lost on long-span work.

Welding

A certificate is a claim about people, not machines.

ISO 3834-2 is the comprehensive tier of the welding quality standard. It requires a named, qualified welding coordinator who is accountable for procedure, qualification and traceability. Ours holds the International Welding Engineer qualification, classified under ISO 14731:2019 §6.2.2.

Our welding procedure qualification records cover processes 135, 136 and 135+121, material group 1.2, at plate thicknesses up to 30 mm.
