Key Benefits of Aluminium Powder Coating

Do you need aluminium extrusions, flat sheets or windows treated to achieve a durable and elegant finish? If so, there are several surface treatment painting options available. However, aluminium powder coating is one of the most popular choices out there.

If you’re unfamiliar with the process, here’s some helpful information about aluminium powder coating and why it’s one of the best surface treatment painting methods.

Aluminium Powder Coating – The Basics

Just like other metals such as steel and titanium, the quality of aluminium products or parts is affected by the weather and environment. Although aluminium technically does not rust, it still is subject to corrosion, especially when exposed to salty or polluted air and other harsh conditions.

When aluminium corrodes, it loses not only some of its integrity and quality but also its aesthetic appeal. Besides, even when aluminium is left untarnished, without some sort of surface treatment, it would be susceptible to scuffs and scratches.

The solution: aluminium powder coating.

The aluminium powder coating process involves the application of electrostatically charged powder coating on the surface of a piece of aluminium metalwork, thereby forming a new layer.

The coated metal product is then allowed to cure in an oven for several minutes. This step in the coating process allows the powder to melt uniformly on the aluminium surface, ensuring a smooth, well-distributed, durable and attractive finish.

The aluminium powder coating process can provide ample protection to aluminium parts from anywhere between 15 and 20 years – or even longer.

This level of durability makes aluminium powder coating an ideal treatment for certain aluminium products or parts like frames, lighting, signage, shower screens, office partitions, electrical housings, patent glazing and blinds.

Aside from the many applications of powder coating in the aluminium industry, this surface treatment process is also widely used in the following:

  • Agriculture
  • Architecture
  • Automotive industry
  • Building construction
  • Electrical equipment
  • Household appliances
  • Metals
  • Outdoor furniture

Other Benefits of Aluminium Powder Coating

As well as enhancing the appearance of and providing a durable coating to aluminium parts, the powder coating process also provides the following benefits:
It is an environmentally friendly process, as it emits zero or near-zero volatile organic compounds (VOCs).

It protects aluminium from corrosion and keeps the metal resistant to abrasions, bumps, heat or sun damage and scratches, as well as to harsh temperatures.

It can produce a thicker coating compared to liquid treatments, without the risk of running or sagging.

It can achieve a range of finishes and special effects, including matte, glossy or metallic, wood effects, and textured finishes. It can also be coloured or colourless.

It is easy to clean and maintain.

Any powder coating over-spray is recyclable, so the process produces very little waste.

Aluminium powder coating is also one of the more cost-effective ways to treat aluminium parts and products, as the cost of treatment depends primarily on the product being treated and the size of the project.
