Abrasive blasting is the first step in the preparation of steelwork for applying coating systems. It’s important for the effectiveness of the applied paint system that proper surface preparation is ensured. Abrasive blasting is a specialised skill and we apply a wealth of experience and knowledge to working with the right abrasive, the correct equipment setup and the optimum techniques to achieve the exact class of blast and surface profile required for every component of your project.

From structural steel in our dedicated blasting workshop to remote site work projects, Gonzalez Steel has built a reputation for achieving quality surface preparation safely, on time and to the highest standards.

Gonzalez Steel specialises in the application of protective coatings with a wide range of options available, ranging from single component enamels to two pack epoxies and polyurethanes. It is vitally important that the right coating system is chosen to protect your steel asset, and just as important that the coating is applied correctly to meet all the needs of your custom project.

Protective steel coatings applied with expert care and attention by Gonzalez Steel provide an extended lifespan and strength optimisation. Our top coatings come in range of colours which increase the style and aesthetic appeal of steel structures when applied.

A number of factors define the right protective steel coating, including: type of structure, product specifications and the environment where the structure is located. These are all factors to take into account when selecting the right coating.

A correctly applied protective coating can provide homes and businesses with rust protection and can offer corrosion control for large-scale industrial structures. Gonzalez Steel can provide the right coating to protect and rejuvenate your domestic, commercial and industrial steel products.

Galvanising is a popular technique which provides outstanding corrosion performance in a broad variety of environments. The galvanising process creates a durable, abrasion-resistant coating of metallic zinc and zinc-iron alloy layers. This process provides excellent toughness, resistance to damage and protection from corrosion. Gonzalez Steel has partnered with two local providers to utilize the best galvanising service available for our clients.
