Powder
Coating of Metals
Powder coating of metals on aluminium and iron. Powder application with polyester powder, curing in an oven at 180–200°C, for maximum durability, aesthetics and certified quality.
Powder Coating
of Metals
Powder coating of metals is the most modern method of metal surface finishing, a solvent-free (VOC-free) powder coating technology that offers excellent resistance to UV radiation, corrosion, scratches and chemicals. At our coating facility in Thessaloniki, Axinar S.A. provides complete powder coating services on aluminium, iron and steel, with certified Qualicoat and Qualisteelcoat processes.
We specialise in aluminium powder coating for architectural applications (window frames, curtain walls, architectural metal elements) and iron powder coating for industrial structures. Polyester powder is applied electrostatically with GEMA equipment and cured in a curing oven at 180–200°C, creating a uniform coating with a thickness of 60–120 µm and maximum durability.
We handle powder coating of structures of every type, powder coating of photovoltaic mounting systems, coating of metal furniture, canopies, carports, lighting poles, frames and industrial components. Every part goes through metal sandblasting and chemical pre-treatment (phosphating) before coating, ensuring excellent adhesion. We use NEOKEM powders and other leading manufacturers.
The cost of powder coating depends on dimensions, geometry, material (aluminium or iron), finish (RAL colours, matt, gloss, textured, metallic, wood-effect sublimation) and quantity of parts. The price of powder coating at Axinar is competitive, with a free quote within 24 hours. Compared to wet paint, powder coating of metals lasts 3–5× longer without peeling or yellowing.
The Process of
Powder Coating of Metals
Sandblasting
Metal sandblasting to remove rust, oil and old paint. Creates a rough surface for maximum adhesion of polyester powder.
Chemical Pre-Treatment
Phosphating and chemical pre-treatment (degreasing, rinsing) for aluminium and iron. Ensures corrosion protection to EN ISO 12944.
Powder Application
Electrostatic application of polyester powder with GEMA guns. The powder is charged electrostatically and adheres uniformly to the metal, thickness 60–120 µm.
Oven Curing
Curing in an oven at 180–200°C for 15–20 minutes. The powder melts and forms a hard, uniform coating with excellent UV resistance and durability.
Automatic
GEMA Coating System
IG07-PA
Constant powder flow
Open 135° angle with reduced wear, guarantees a constant powder flow over long periods without interruptions.
Plug & Convey
All connections use a quick-release system. Quick disconnection and reconnection, zero production downtime.
Optimised colour change
Axial sealing and smooth-flow design minimise residual powder during colour change.
DVC Technology
Combined with DVC technology, an accurate and repeatable coating thickness of 60–120 µm is ensured — the same result from part to part.
Low operating cost
Less air for more powder, reduced component wear and reduced compressed air consumption.

Powder Coating
vs Wet Paint
Powder Coating
Powder coating of metals uses dry polyester powder that is cured in an oven. Zero VOC emissions, maximum durability.
- Thickness 60–120 µm in a single pass
- Durability 15–25+ years outdoors
- VOC-free, environmentally friendly
- Resistance to UV, chemicals, scratches
- Full RAL colour range
- Finishes: matt, gloss, textured, metallic
- Qualicoat / Qualisteelcoat certification
Wet Paint
Traditional wet paint uses liquid paints with solvents. Suitable for very large parts or special applications.
- Thickness 20–40 µm per coat
- Durability 3–8 years (needs renewal)
- Contains VOC, solvent emissions
- Sensitive to UV, peeling
- Limited colours per range
- Requires multiple coats
- Lower initial cost, higher lifecycle cost
Advantages
of Powder Coating of Metals
Long-Term Durability
Powder coating of metals lasts 15–25+ years outdoors without peeling, yellowing or colour loss. Excellent UV resistance and salt spray durability to EN ISO 12944.
Certified Quality
Aluminium powder coating to Qualicoat and iron powder coating to Qualisteelcoat. Controlled coating thickness 60–120 µm, adhesion and hardness tests.
Complete Fabrication
Laser cutting, press brake, welding, deburring, metal sandblasting, powder coating — one point of contact, one finished product ready for installation.
Competitive Cost
The cost of powder coating depends on dimensions, finish and quantity. The price of powder coating at Axinar is 2–6× lower in lifecycle cost compared to wet paint, due to zero maintenance.
RAL & Special Colours
Full RAL colour range, RAL colours in matt, gloss, textured and metallic finish. In addition, wood-effect powder coating (sublimation) for architectural applications.
Fast Delivery
Powder coating of metals is integrated into the production timeline. Metal coating facility in Thessaloniki, coordinated production without delays.
