Hot dip galvanizing is a corrosion protection method for steel and iron structures. The process involves cleaning the surface of the metal, then dipping it into a bath of molten zinc. The zinc reacts with the iron or steel to form a metallurgical bond, creating a protective layer on the surface. This layer provides a barrier against corrosion and rust, extending the life of the metal.

Hot zinc metal spraying is a corrosion protection process where a layer of zinc metal is formed on the steel’s surface by spraying atomised zinc onto it. The sprayed zinc material reacts with the metal surface, forming a protective layer that acts as a barrier against corrosion. This method is commonly used in industrial, construction, and marine applications, and is known for its high level of durability and long-term protection against corrosion. Being a listed process that requires special licensing from the City of Cape Town, Galvatech is authorised to apply these coatings.

Industrial shot or sandblasting is a surface treatment process where a high-speed stream of abrasive material is directed onto a surface to remove contaminants, rust, paint, or other coatings. Blasting is the preferred surface preparation method for applications of new paint systems. The abrasive material we use is either garnet or steel grit, depending on the desired profile for the application.

Conventional wet spraying is a coating method where a liquid material is applied to a surface using a spray gun. This process results in a uniform, smooth, and consistent finish. This method is commonly used in industrial and architectural applications, and offers protection from environmental factors such as corrosion and UV light. With a wide range of products available, conventional spray painting can offer solutions to almost any application. We recommend sand or shotblasting prior to application to enhance adherence.

Powder coating is a metal finishing process where a dry powder material is electrostatically charged and then baked onto a metal to form a hard, durable finish. This method offers protection from environmental factors such as corrosion, fading, and chipping and provides a consistent, uniform appearance. Powder coating is often used in industrial, residential, and architectural applications. Normally used to coat internal balustrading or steel ornaments for decorative finishes with low exposure to harsh corrosive environments.
