Powder coating in steel fabrication: The finishing touch

What is powder coating?

Powder coating is a dry finishing process where a fine powder (made of resin, pigment, and additives) is electrostatically applied to a surface and cured in a high-temperature oven. This creates a tough, uniform, and corrosion-resistant coating making it highly effective for metal fabrication projects.

Unlike traditional paint, powder coating contains no solvents and emits near-zero volatile organic compounds (VOCs), making it a sustainable finishing solution.

 

Why powder coating is ideal for steel fabrication

1. Durability that lasts

Powder-coated steel resists corrosion, chipping, scratching, and UV damage. It’s ideal for outdoor steel structures, industrial machinery, and fabricated metal parts exposed to outdoor environments.

2. Superior corrosion protection

Powder coating provides a long-lasting barrier, which helps to prevent rust on steel fabrication products, especially after preparing the surface properly like sandblasting or chemical cleaning methods.

3. Efficient and consistent application

This method provides even coverage over weld seams and complex shapes, making it perfect for custom metalwork and industrial steel fabrication. No drips or streaks, just a clean and professional finish.

4. Professional appearance

Whether we’re spraying a steel staircase matte black or creating yellow safety rails, powder coating enhances form and function. It increases the visual appeal of everything from metal furniture to steel signage.

5. Eco-Friendly and Cost-Effective

Powder coating is considered a green finishing method. It has virtually no waste and uses less materials. This makes the process a cost-effective finishing method for our customers to choose.

 

The powder coating process for fabricated steel

1. Surface Prep
   We clean and blast the product, removing any oils, rust, and mill scale for optimal powder coating application.
2. Powder Application
   An electrostatic gun charges and applies the powder in a spray, evenly across the steel surface.
3. Curing
   Our powder coated products are heated to approximately 191–204°C, bonding the powder into a durable, protective layer.
4. Cooling & Inspection
   The coated part cools into a smooth finish, ready for us to send to the customer.

Common powder coating applications in steel fabrication

• Architectural steel: fencing, gates, beams
• Industrial components: viewing platforms, support frames, machine housings
• Agricultural steel: tool mounts, equipment frames, storage racks
• Custom metal projects: signage, art installations, steel staircases
