Treatments & Paint

GJM offers powder coating and wet spray painting on steel and aluminium components and fabrications on site. We can powder coat up to 4m x 3m x 3m.

Powder coating is based on the principles that objects with the opposite electric chargers (positive and negative) attract one another. Powder particles are negatively charged by passing them through a special spraying gun. This results in an electric field between the spray gun and the earthed component. The powder particles then follow the field lines and adhere to the product. The component is then conveyed to an over where the powder is baked at temperature of 160 to 200 degrees C for approximately 20 minutes. Most conducting or thermally stable materials are suitable for powder coating and metals are particularly good due to their high electrical and thermal conductivity. Complex metal components can be powder coated evenly with excellent adhesion. 

GJM uses quality powders supplied by recognised manufacturers and processes components through a modern paint plant system with either three-stage or five-stage pre-treatment. Regular quality checks are made along with stringent spot checks carried out at intervals by quality engineers. Full traceability is maintained throughout.
