Metal Surface Treatment

Our expert metal surface treatment services not only prep your products for coating but also create a smooth and durable finish, enhancing the appearance and extending the lifespan of your metalwork. Trust us to prevent rust and corrosion while delivering exceptional results.

Metal Surface Treatment (Secondary Operation)

Secondary Process to surface finish on metal parts from stamping to surface finishing, assembly and packing. Variety type of surface finishes such as:

ED coating, powder coating, wet spray painting, aluminium anodizing, zinc plating, and silk printing.

Wet Spray Painting: Auto spray

We use auto spray (automotive spray) in our metal surface treatment such as motorcycle parts as we do manufacture motorcycle parts. By applying auto spray on the motorcycle parts and other finished parts we produce, we can assure that they are protected from corrosion, heat changes, UV light and bumps.

Wet Spray Painting: Robot Spray

For years, we’ve been using robot sprays as part of our metal surface treatment to ensure that our productivity is maintained and improved. Paint functions as an effective protectant against the harsh environment or corrosion resistance, which can impact the aluminium substrate. We can ensure that the metals we need to paint are evenly sprayed with consistent speed and just about perfect precision while minimising the cost of wasted painting by using robot sprays in our metal surface treatment. Textured specialised effects and shiny metallic effects are both possible through wet spray painting.

Silk Coating

Silk coating, also known as silk screen printing, is one of the methods for metal surface treatment whereby blades and squeegee are used for painting metal surfaces. In addition, silk coating can be applied on many different types of metal such as stainless steel, aluminum, brass, etc. 

Spot Welding

Spot welding is a welding technique which involves applying pressure and electric current to the weld regions to join metal parts together. We will continue to metal surface treatment to paint the metal parts that we make once we have joined metal parts together.

Powder Coating

Powder coating is an ecologically friendly method that we use in our metal surface treatment since it is non-toxic and inert. Furthermore, it offers a relatively durable surface compared to what liquid paint can provide without diminishing the attractiveness of the metals.

Zinc Plating

Zinc plating consists of the electrodeposition process of a thin coating layer of zinc onto the surface of another metal. This approach is chosen to be applied for our metal surface treatment because it has the inherent capacity to prevent corrosion from reaching the metal underlying surface.


Hairline metal surface treatment is mostly used on the surface of stainless steel in construction and equipment tools, giving it a linear texture. Other varieties of hairline metal surface treatment, such as cross hairline and circular hairline, are available at Grille Tech in addition to the traditional linear hairline metal surface treatment.

Aluminum Anodizing

In a nutshell, anodizing is an electrochemical process that allows a metal surface to become more corrosion resistant, wear resistant, and long-lasting, particularly for aluminium metal parts.  It is relatively safe and produces fewer harmful environmental by-products. Hence, we offer aluminium anodizing service as part of our metal surface treatment in order to be as ecologically friendly as possible.
