Powder coating is a dry powder that is applied electrostatically and is then cured under heat to allow it to flow and form a skin. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, aluminium extrusions and most metal surfaces.

Powder coating is a high quality finish found on thousands of products you come in contact with every day. Powder coating protects the roughest, toughest machinery as well as the household items you depend on daily. It provides a more durable finish than liquid paints can offer, while still providing an attractive finish. Powder coated products are more resistant to diminished coating quality as a result of impact, moisture, chemicals, ultra violet light, and other extreme weather conditions. In turn, this reduces the risk of scratches, chipping, abrasions, corrosion, fading and other wear issues.

M & P Engineering is one of a few select applicators to offer the Metal Spray system.

Metal Spray is a coating system that utilises the unique characteristics of the metal spray galvanising process and the powder coating process that enables a performance warranty against corrosion of the base metal for a period of ten years.

The fabrication is scrutinised before preparation begins. Abrasive blasting to class 3 provides the cleanest profile to the surface of steel. Spray galvanising of the prepared steelwork leaves a pure galvanising laying free of dags and un-compromised by the need to dress the surface for coating. Multiple coating layers of powder coat secure the galvanising layer and provide the end user with an architectural finish on their external steel.

Our ability to control the parameters of the various stages in the system, determine the performance results when utilising the Metal Spray Coating System. These stages occur before the coating application begins and both design and fabrication

The process of metal spraying is to mix and ignite gas fuel and oxygen to produce a flame. The wire material is fed into the flame. The material is then melted and compressed air passing through the spray nozzle atomises and the molten metal is sprayed onto the surface.

The benefit of using this technology is to protect and greatly extend the life of a product in hostile environments and situations were coatings are essential for longevity.

Metal spraying has been around for many many years and has proven itself to be very effective in a wide range of applications. Metal spraying is a very flexible process, that can be applied to a wide range of materials. Basically if a material can be heated to its melting point without boiling away, than the material can be sprayed. The process is also transportable, so structural steelwork can be sprayed on-site or repaired, where other processes may have removed the galvanising.

This process is also suitable for structural components which cannot be dipped into a galvanising bath due to a large size, or for objects that would become distorted during a hot-dip galvanising. This method is also used on sections of objects that cannot be accessed by hot-dip galvanising.

Abrasive blasting is the operation of forcibly propelling a steam of abrasive material against a surface under high pressure to roughen a smooth surface to allow an alternative process to cling to the material or to remove contaminants from the surface of the material.

Compressed air is used to propel the blasting material (media). M & P Engineering uses garnet as its preferred media, being the most abrasive, effective and environmentally friendly source on the market today.

At M & P Engineering, we have a very large blast room. We are able to facilitate any job up to approx. 18 metres in length and 6 metres wide.
