Built for Ducting, Refrigeration & HVAC Projects
Four core product lines, produced in our own workshop and supplied with the specifications, materials and packing overseas buyers need.

A Working Factory, Not Just a Trading Office
Stamping, forming, finishing and inspection happen under one roof. You can see how parts are made before you place a repeat order.
Source factory
Stamping, forming and assembly are done in our own workshop, so you deal with the maker, not a middle trader.
Custom and tooling
We build tooling in-house and produce parts to your drawing, sample or 3D model, with a sample before volume runs.
Quality control
Checks run from incoming material to finished packing, so dimensions and finish stay consistent batch to batch.
Export packing
Cartons, labels and pallets are packed to your export requirements, with documents prepared for shipping.
