ChinSource Powder Coatings
Polyester powder coatings are the industry standard for anything that lives outdoors. Formulated for weatherability and UV stability, they hold gloss and colour through years of sun, rain and temperature cycling — on architectural profiles, fences, facades and outdoor furniture.
Why Choose Polyester Powder Coatings
- Outstanding weatherability — resists UV degradation, chalking and gloss loss in exterior service.
- Colour stability — keeps RAL shades accurate season after season.
- Mechanical toughness — good impact and bending resistance for formed and handled parts.
- Architectural weathering grades — architectural grades for curtain walls, window and door profiles.
- Wide finish library — metallic, sand, hammer, wrinkle, wood grain and marble effects.
Typical Applications
- Architectural — curtain walls, aluminium profiles, doors and windows requiring long-term exterior weathering performance.
- Aluminium profiles — wood grain and solid finishes for windows, doors and facades.
- Fences & railings — long-term exterior colour and corrosion protection.
- Outdoor furniture — garden and patio furniture exposed to weather.
- Facade panels — decorative and protective finish for building envelopes.

Frequently Asked Questions
Why is polyester the standard choice for outdoor products?
Polyester powder coatings are formulated for weatherability and UV resistance. They retain gloss and colour far better than epoxy when exposed to sunlight and rain, which is why they are the standard for architectural profiles, fences, outdoor furniture and facades.
What weathering performance do you offer for architectural work?
Our architectural grades are developed for long-term exterior weathering on curtain walls, aluminium profiles, doors and windows. Tell us the project specification and we will match the required standard.
Can polyester powder be used indoors?
Yes. Polyester works well indoors too, though where flow and levelling on interior appliances is the priority, a hybrid (epoxy-polyester) grade may give a smoother film. We will advise based on your part.
Which finishes are available?
Solid RAL colours, metallic, sand, hammer, wrinkle, wood grain and marble effects. Gloss levels 30%, 60% and 80%, with custom colour matching on request.
How fast can you match a colour?
Send us a sample or a RAL number. We match colours and finishes accurately, including metallic, sand and textured effects, and return a matched panel for approval before production.
What certifications does the factory hold?
ISO 9001 quality management, ISO 14001 environmental management, REACH compliance, UL certification and C5 anti-corrosion rating. COA and MSDS are issued with every shipment.
