Powder Coating Services Auckland

What is Powder Coating?

Powder coating is a dry finishing process used widely across Auckland for automotive, architectural, and industrial metalwork. Electrostatically charged powder particles are applied to a metal surface and then cured under heat to form a smooth, durable finish. Unlike traditional liquid paint, powder coating creates a much tougher finish that's resistant to scratching, chipping, fading, and corrosion.

At Coating Lab, we've done this for years, turning out consistent, hard-wearing finishes for customers across Auckland. From classic car parts to architectural metalwork and industrial equipment, our powder coating service delivers professional results every time.

Why Choose Powder Coating?

• Superior Durability: Significantly outlasts wet paint when properly applied and maintained
• Scratch & Chip Resistant: Perfect for high-traffic and outdoor applications
• UV Stable: Resists fading from sunlight exposure
• Environmentally Friendly: No solvents or VOCs released during application
• Uniform Finish: Consistent coverage even on complex shapes
• Cost Effective: Long-lasting protection reduces maintenance and recoating costs

Aluminium Powder Coating

Can you powder coat aluminium? Yes — aluminium is one of the most popular substrates for powder coating, and it produces excellent results when the surface is properly prepared. At Coating Lab, we regularly powder coat aluminium for both residential and commercial projects across Auckland.

The key to a long-lasting finish on aluminium is proper pre-treatment. Unlike steel, aluminium requires a specialised conversion coating process to ensure the powder adheres correctly. We use a chrome-free conversion coating as part of our pre-treatment line, which provides the chemical bond needed between the aluminium surface and the powder. Without this step, powder coating can peel or flake prematurely — which is why proper preparation matters more than the coating itself.

Common aluminium items we coat include window frames, balustrades, outdoor furniture, automotive parts, shopfronts, and architectural panels. Aluminium's lightweight properties and natural corrosion resistance make it an ideal candidate for powder coating, adding both colour and an additional layer of protection against the elements.

Steel Powder Coating

Steel is the most common substrate we powder coat at Coating Lab. From structural steel and fabricated components through to gates, fences, and machinery parts, powder coating provides a tough, corrosion-resistant finish that outperforms traditional paint in most applications.

Surface preparation is critical when working with steel. Most steel items require sandblasting to remove mill scale, rust, and old coatings before powder can be applied. Sandblasting creates the surface profile needed for optimal adhesion, ensuring the finished coating bonds properly and lasts. Items with heavy rust or multiple layers of old paint will need more extensive preparation.

We coat steel for a wide range of applications including structural steelwork, fabricated frames and brackets, driveway gates, pool fences, security fencing, agricultural machinery, and industrial equipment. If you also need corrosion protection for steel in harsh environments, ask us about our zinc arc wire spray service as a primer coat before powder coating.

Powder Coating Cost

The cost of powder coating depends on several factors, and every job is different. The main variables that affect pricing are the size of the item, the amount of surface preparation required, your colour selection, and the quantity of items being coated. A single small bracket will naturally cost less than a full set of gates or a batch of architectural panels.

Items that arrive with heavy rust, old paint, or complex shapes require more preparation time before they can be coated. Surface prep — including sandblasting, chemical cleaning, and masking — often makes up a significant portion of the overall job cost. Choosing a standard colour from the RAL range or our stock powders can also help keep costs down compared to custom colour matching.

Rather than publishing fixed prices, we provide accurate quotes based on your specific project. This ensures you only pay for what your job actually requires. Contact us for a free quote, or read our blog post on powder coating costs in New Zealand for more detail on what affects pricing.

Colours and Finishes

We offer a wide range of colours and finishes using quality powder systems from Dulux and Interpon, alongside the full RAL colour range. Whether you need a standard colour or something custom-matched from a sample, we can accommodate most requests.

Available finish types include gloss, satin, matte, textured (wrinkle, hammer-tone, sand), and metallic effects. Black powder coat remains one of our most popular options — available in gloss, satin, and matte. We can also colour match from physical samples, RAL codes, or other colour systems to get the exact result you need.

Wheels and Rims

We powder coat both alloy and steel wheels in a range of popular finishes including gloss black, satin black, gunmetal, and custom colours. Powder coating gives wheels a durable finish that resists brake dust, road grime, and stone chips far better than standard paint. Visit our dedicated wheels and rims page for more information on finishes and the process involved.

Our Process

Every powder coating job at Coating Lab follows our established process:

1. Inspection: We assess your items and discuss your requirements
2. Surface Preparation: Items are cleaned, degreased, and sandblasted if required
3. Pretreatment: Chemical treatment ensures optimal adhesion
4. Powder Application: Electrostatic spray gun applies the powder evenly
5. Curing: Items are oven-cured at the correct temperature for the specific powder system — different products require different curing temperatures for optimal hardness
6. Quality Check: Final inspection ensures consistent coverage and finish
