Powdercoat Colour Options and Finishes

Most of our powdercoated products are manufactured using zinc-coated steel, which includes a continuous hot-dip zinc coating (20 microns) for enhanced corrosion resistance.

The pre-treatment process consists of four stages:

1. Stage 1 & 2 – Cleaning and Phosphating:
   Removes oils and grease, then applies an Iron Phosphate coating to improve paint adhesion and ensure even coverage.

2. Stage 3 – Fresh Water Rinse:
   A pressurised rinse using recirculated fresh water.

3. Stage 4 – Final Seal Rinse:
   Applies a final sealing coat to prepare the surface for powdercoating.

We conduct regular Titration Tests on phosphate tanks to ensure compliance with specifications set by our pre-treatment chemical and powdercoat suppliers.

B&R offers a range of standard powdercoat colours and finishes for all electrical enclosures. Additional colour options are available on request. Speak with one of our sales representatives to explore custom powdercoat finishes tailored to your needs.

Our standard industry colours include:

• Light Grey (RAL7035) – Ripple finish, used for enclosures and external components.

• Pearl White Gloss – Used exclusively for internal components.

• Pearl White Ripple – Available for enclosures and external components upon request.

All powdercoated metallic enclosures are finished using a modified polyester paint, tested rigorously to meet our in-house standards and certified under our ISO 9001:2015 Quality Management System.

Our coatings undergo a series of strict tests to ensure durability, adhesion, and compliance with Australian standards.

1. Powdercoat Thickness Test

• Ripple Finish: Average 100 microns
• Gloss Finish: Average 70 microns
• Minimum Thickness:
  • Exterior: 90 microns
  • Interior: 60 microns
• Complies with AS/NZS 4506:2005
• Measured with calibrated paint inspection gauges to ensure accuracy.

2. Cure Test (Solvent Resistance Method)

• Confirms that the powdercoating is fully cured.
• Tested against known cured panels.
• Complies with AS/NZS 4506:2005

3. Adhesion (Cross Cut Test)

• Ensures strong adhesion between the coating and substrate.
• Complies with AS/NZS 1580.408.4:1993

4. Paint Colour Comparison

• Every powdercoat batch is visually compared against approved colour samples.
• Samples are calibrated to match AS 2700-2011 standards or customer-supplied references.

Powdercoated finishes absorb solar energy, which can raise internal enclosure temperatures when exposed to direct sunlight. Below are estimated temperature increases for our standard colours:
