Materials and thickness

Parts we make

Why customers choose us

Seven tanks, not wipe and spray

Preparation stays under the same accountable production system as fabrication.

Powder and wet paint under one roof

Parts are routed to the finish that suits the specification, powder coat or liquid paint, without leaving the site.

No transport between operations

Assemblies move from welding through blasting, coating and oven cure without leaving the site.

Coating: the technical detail behind this page

Seven-tank pretreatment, phosphating, shot blasting, powder and wet paint selection, film thickness and the failure modes that show up two monsoons later.

Degreasing mild steel parts before coating

Why a 1 µm oil film defeats powder on mild steel, the alkaline cycle that removes it, the water-break test that proves it, and the film build to specify.

Degreasing before powder coating

Why degreasing decides powder adhesion: what has to come off, how a seven-tank line works, rinse conductivity, film build, cure and the failures it prevents.

Shot blasting profile: anchor pattern and adhesion

How shot blasting profile controls coating adhesion: the Rz range to specify, how to measure it, and why a 90 µm profile under 60 µm of powder fails early.

Do you take powder coating as job work?

Yes, subject to part size and condition. Powder booth capacity is 18 ft by 14 ft.

Can you match our colour?

Yes, to RAL or a supplied sample, in both powder coat and wet paint.

Do you shot blast before coating?

Where the part and specification call for it. We have a 16 ft by 16 ft blast chamber.

Do you apply primers?

Yes. Primer and intermediate coats are applied in the wet paint booth before the topcoat.

How do you handle effluent?

Through our own effluent treatment plant, operated under ISO 14001:2015 certification.
