Powder coated steel for outdoor furniture is the global standard for garden chairs, patio tables, parasol bases, BBQ frames and planter boxes — chosen by manufacturers for its superior weatherability, full RAL color range and zero-VOC processing. ChinaCNU Steel supplies polyester TGIC powder coated steel coil tailored to outdoor furniture OEMs, with film thickness, gloss level and color matched to your end-product brand.
Why Powder Coated Steel Dominates Outdoor Furniture
- UV Stability: Polyester TGIC and SDP powders retain ≥ 90% gloss after 2,000 hours QUV-A exposure.
- Chip Resistance: 60–100 µm powder film resists impact from gravel, garden tools and stacking damage during shipping.
- Salt-Spray Performance: 1,000+ hours per ASTM B117 with proper zinc primer, ideal for coastal and poolside furniture.
- Brand Color Consistency: RAL or Pantone matched per batch, ΔE ≤ 1.0 between production runs.
- Eco Compliance: Zero VOC, REACH-compliant, suitable for EU, US and AU furniture imports.

FAQ
Will powder coated steel furniture rust outdoors?
Not when manufactured correctly. Use galvanized steel substrate (Z120 g/m² or higher), apply zinc-rich epoxy primer, and finish with polyester TGIC topcoat at 60–100 µm. This stack delivers 1,000+ hours salt-spray resistance and 15+ years service life in coastal environments.
What thickness of powder coating is best for outdoor furniture?
60–100 µm is the sweet spot. Below 60 µm, edge coverage suffers and chips appear at sharp corners. Above 100 µm, you risk sagging, orange peel and unnecessary cost. For premium product lines specifying AAMA 2604, increase to 70–90 µm of SDP polyester.
Can you supply powder coated steel for both flat-pack and welded furniture?
Yes. We supply powder coated coil for stamped seat backs and table tops, plus powder coated steel tube (round, square, rectangular) for frames. Tube can be color-matched to the sheet for visual consistency.
