We coat metalwork from trade and private individuals alike and pride ourselves on our friendly approachable service, our quality and our flexibility. The variety of items we coat varies from old domestic radiators and sculptures to commercial fencing and structural beams. If you are unsure as whether your metalwork can be powder coated then please get in touch. It doesn’t matter if you have one item or a thousand, please give us a call or send us an email.
We also powder coat directly onto aluminium and the process is similar to how we powder coat directly onto mild steel except we chemically rather than mechanically etch the metal surface.
Galvanizing and powder coating
Fettle
The galvanized steelwork arrives from our galvanizing plants and is fettled smooth.
Clean
After hanging onto our overhead rails, the steelwork is moved into our degreasing chamber.
T-Wash
After cleaning the steelwork is then chemically etched using a T-Wash in our automated pre-treatment system.
Dry
Before powder coating, the metal must be completely dry. Once through our pre-treatment the steelwork is moved into our dryer.
Powder coating
The steelwork is now ready to paint. After earthing, it is sprayed with a uniform coating of paint powder in the coating booth.
Cure
After it is covered in dry paint, the steelwork is moved into the curing oven where it is heated to 180-200oC for around 10 minutes until baked hard.
Post treatment
Once out of the oven it is inspected and allowed to cool. The appropriate packaging is then used to protect the painted steelwork before despatch.
Powder coating only
Blast
The steelwork is first lightly blasted to remove rust and mill scale.
Dry
Before powder coating, the metal must be completely dry. Once blasted the steelwork is moved into our dryer.
