Introduction
Architectural curtain wall powder coating is the protective and decorative finish applied to window frames, doors and curtain wall extrusions. As a dry powder cured by heat it forms a hard, uniform film on aluminium, galvanised steel and mild steel, in a wide range of colours, gloss levels, metallic, wood-grain and candy effects.

Buyer FAQs
Which resin do I choose?Epoxy for corrosion barrier (indoor), hybrid for chemical/mechanical balance, polyester for exterior UV and weather stability.What can be powder coated?Any metal that holds an electrostatic charge and tolerates cure heat: mild steel, galvanised and plated steel, aluminium, stainless steel and most alloys.
Are all colours the same price?No. Textured, candy, metallic and special-effect shades use more costly pigments and are priced accordingly; standard RAL colours are more economical.Is it safe for consumers?Cured powder film is widely used on furniture, appliances and children’s products; it is a solvent-free, low-VOC finish once fully cured.
