Metspray are specialists in the application of a fully comprehensive range of protective coatings (liquid coatings, commonly referred to as paint) for structural steel, steel parts, infrastructure and assets, in accordance with industry specifications and standards.
Whether your project is in the commercial, industrial, marine, oil and gas, or electricity industry, and no matter the surface finish required, with our extensive range of equipment and highly experienced craftsmen, we have you covered. We provide coatings that range from the products described in AS NZS 2312 through to the most complex systems, for specific high-risk environments. These include but are not limited to: •Single Pack Coatings – etch primers, enamels, acrylics, etc. •Inorganic Zinc Silicates •Epoxy Coatings – primers, zinc rich epoxies, high build, ultra-high build, and potable water epoxies •Polyurethanes and Polysiloxanes •MIOX Coatings •Fluoropolymers •Marine Coatings •Non-Skid Coatings •Speciality Coatings - high temperature, highly abrasion resistant or chemical resistant coatings Call Metspray to discuss your project and ensure the right coating system is provided for maximum protection against the environment.
What preparation is required before coating application? Generally, it is expected that new steel will be abrasive-blasted before being coated. Please see our abrasive blasting FAQs for more information on abrasive blast standards. To ascertain the best solution for surface preparation of existing steel and to minimise compromise to the overall performance and durability of the coating system, it will first need to be assessed. A comprehensive coating survey by an industry professional is the best option.
What equipment is used for the application of protective coatings? Depending on the structure to undergo coating and the type of coating system applied, a mix of hand and spray application will be used. Hand application is generally via brush, roller, mitt, or flow. For spray application, conventional, airless, air-assisted, or plural spray pumps are used.
What is the best coating system? There is no best coating system. Rather every project should be assessed with the following factors in mind: the expected life span of the substrate/structure; its service and construction environments; ease of and time frame for application; ease of ongoing maintenance. All of this is taken into consideration to determine the best solution for the project.
What is the purpose of the coating? The most common purpose is to provide protection against corrosion. However, coatings can also be used to provide UV protection, anti-slip, abrasion resistance, chemical resistance, aesthetics, or a combination of these.
Are there different standards of finish and does this affect aesthetics? Yes, finishes for both protective and intumescent coatings can be defined as: 1.Industrial Finish – The coating system itself achieves the required performance and corrosion protection. No requirements for aesthetics. Minor runs/drips/sags and orange-peel finish are acceptable as long as they do not compromise corrosion protection. The surface should have an acceptable level of uniformity and no visible defects when viewed from 10m. 2.Commercial Finish – As for an Industrial Finish, however, a satisfactory level of aesthetics is required and no visible runs/drips/sags when viewed from 5m. The surface will predominantly be smooth and uniform and have an even gloss level. Minor ‘orange-peel’ and/or brush marks are acceptable. 3.Architectural Finish – The coating is to have a very high level of aesthetics: even and smooth with a consistent gloss level when viewed from 2m and will have no runs/drips/sags on the surface. This finish level usually applies to visible steel only. 4.Bespoke Finish – The highest level of aesthetics: completely even and smooth with consistent gloss level and desired texture throughout. No defects.
