Why Choose Powder Coating?
Outdoor Durability
Resists UV exposure, salt, and chemicals. Designed to prevent peeling and fading over 10–15 years of use.
Covers Surface Imperfections
A 60–100+ μm coating helps conceal minor scratches, casting flow marks, and extrusion die lines.
Complete RAL Color Range
International RAL colors with glossy, matte, textured, and wood-grain finishes.
Zero VOCs — Environmentally Responsible
No volatile organic solvents. Up to 95% of overspray powder can be recovered and reused; RoHS and REACH compliant for EU/US exports.
A Range of Surface Finishes
Glossy
Highly reflective, elegant, and easy to clean. Popular for interiors and electronic equipment.
Matte
Non-reflective, conceals minor imperfections, and resists fingerprints. Ideal for aluminum doors and architectural frames.
Textured
A textured surface adds visual depth and resists scratches. Suitable for outdoor equipment.
Wood Grain
Heat-transfer sublimation creates a natural wood appearance on powder-coated extruded aluminum profiles.
Equipment & Process
Integrated Automated Coating Line
A durable finish begins with chemical pretreatment — a critical step that some smaller coating facilities skip to reduce costs.
01
Chemical Pretreatment
Automated washing: degreasing → chromate or chrome-free conversion coating → thorough drying. Essential for lasting adhesion.
02
Automated Conveyor Coating Line
Modern electrostatic spray guns distribute powder evenly across complex shapes and recessed areas. Heavy-duty overhead conveyor.
03
Temperature-Controlled Curing Oven
Curing at 180°C–200°C according to the powder type (epoxy, polyester, or acrylic) forms a durable finish.
04
Pre-Shipment Laboratory Inspection
Coating thickness, cross-hatch adhesion, impact, and salt-spray tests are performed before export packing.
