Powder Coated Fasteners

Often, an application demands a coloured fixing to coordinate with the colour of its housing – for example in a commercial vehicle or outdoor furniture. If it doesn’t require a match, then a coloured fixing can be used to provide a striking finish to a job.

There are a spectrum of conventional colours, but custom colours are also available, as well as colour matching – so if there’s a deviation to the green that you’re looking for, the powder coating can look the same.

It is a popular process to apply colour to a fastener, across a range of material variants, allowing for a more pleasing aesthetic.

The Powder Coating Process

The process uses finely milled particles of pigment and resin. The particle size of pigments is critical in determining many of the properties of the colours applied and can have an effect on numerous things, including:

  • Opacity
  • Colour
  • Hue
  • Tinting Strength
  • Gloss
  • Durability
  • Viscosity

These particles of pigment and resin are sprayed onto the fastener by using an electrostatic spray process; which involves the method of administering a coating to a metal surface via the law of attraction between positively and negatively charged particles. The process causes these charged particles to permanently bond to the surface of the metal on whichever fastener, be that a nut, bolt or screw.

Once this has been bonded, the powder is heated and fused before being smoothed into a coating and placed into a curing oven – which melts the powder onto the metal and reduces the risk of chipping, damage, fading or fatigue. The finish is robust.

Powder Coating Colours

There is a wide range of colours available for use as powder coating, often grouped as RAL colours. The initial group of RAL colours was limited to 40 colours. Nowadays there are over 2000 shades – but only 200 or so are commonly used within the United Kingdom for powder coating under the group of ‘RAL Classic’.

Custom colours are available – but you’ll likely find what you’re looking for has a RAL number.
