Why Choose Powder Coating?

Powder coating offers a tough, uniform, and environmentally friendly finish that outperforms traditional wet paint in durability, colour retention, and resistance to weathering.

Key benefits include:

Superior corrosion and abrasion resistance
Uniform, high-quality surface finish
Long lifespan in outdoor and industrial conditions
Wide range of colours and textures

Pretreatment for Optimal Powder Coating Results

We do extensive preparation before powder coating to ensure better adhesion and a longer-lasting finish.

Chemical cleaning, sandblasting and Garnet blasting
Steel parts are sandblasted and then coated with a zinc-rich primer
Final powder coat applied in your chosen finish and colour
Aluminium parts go through a pre-treatment tank process

Pretreatment Acid & Chromate tanks

For the best preparation of aluminium powder coating at GCI, we have also installed Acid & Chromate tanks to ensure that all aluminium components are thoroughly cleaned and prepared for the optimum powder coating result.

Acid tanks remove contaminants, oxides, and oils from metal surfaces
Chromate tanks to enhance bonding and durability
Compliant with environmental and safety standards
Critical step for ensuring long-term coating performance
Bead Blasting

Bead blasting is a precision finishing process where fine glass beads or other abrasive materials are propelled at high pressure to clean and refine surfaces. This method is widely used in manufacturing to achieve smooth, uniform finishes on metal parts, as well as to remove rust, paint, scale, or surface contaminants. Beyond metal, bead blasting can also be applied to plastic and glass to create a consistent texture or decorative finish.

Bead Blasting’s Applications
Peening: Used to relieve stress in metal components
Deburring: Used to remove sharp edges from machined parts
Cleaning: Used to remove contaminants such as rust, paint, and oil from surfaces
Finishing: Used to create a matte finish on surfaces
Polishing: Used to create a shine on metal surfaces

What Makes Our PowderCoating Different?
Our facility includes Sand and Garnet blasting booths to ensure optimal substrate preparation of mild and stainless steel prior to commencement, a vital part of our process that underpins the quality of a GCI finish. Garnet blasting is typically used where added protection is required for metal products that may be exposed to corrosive chemicals, water, temperature variations or elements.
These booths enable our team to prep a wider range of components – from the smaller metal fixings to large fabricated structures. When open to the elements aluminium undergoes oxidation, which forms a thin layer of aluminium oxide on its surface. As such aluminium requires rigorous cleaning prior to Powder Coating to ensure effective coverage and bonding.
For the best preparation of aluminium at GCI, we have also installed Acid & Chromate tanks to ensure that all aluminium components are thoroughly cleaned and prepared for the optimum painting result.
For a durable and lasting quality finish in gloss, matte and satin we insist on using the Dulux and Interpon range of Powder Coating materials, which also gives our clients access to a huge range of colours. Within our facility, we have installed an industrial-sized fan forced baking oven to cater for most powder coating requirements.
