Mill Steel

Mill is untreated, also known as "mild" or "black" steel. It has no coatings or chemical additions to protect it against corrosion. In order to resist corrosion, the metal should be properly treated in a manner appropriate to protect it against corrosive elements present in the environment it is being installed in. Such treatments can be applied before or after final product fabrication, and can alter its appearance depending on the method chosen.

Hot Dip Galvanised Steel

During the Hot Dip Galvanising process, pre-fabricated steel items are chemically treated and then totally immersed in molten zinc, resulting in all of their surfaces being completely coated.

The most important advantage of the process is the overall coating thickness, which provides dual protection against corrosion through an overall barrier, and then a secondary defence of zinc, which gives the steel protection through galvanic action.

Hot Dip Galvanised products are recommended for prolonged outdoor exposure because their coating will offer them protection for years in environments where they are exposed to the weather. EzyStrut has onsite access to Korvest Galvanisers, meaning all our Hot Dip Galvanised steel products can be supplied quickly, with superior quality control, and finished to higher standards. Furthermore, all of EzyStrut's Hot Dip Galvanised products are finished to meet AS/NZS4680:2006.

Pre-Galvanised Steel

Pre-Galvanised products are fabricated from steel that has already been galvanised. They have a clean looking appearance that makes them visually pleasing and a good choice for inside installations where they can be seen. These products are suitable for extended exposure in dry, normal or mildly corrosive environments, but are not typically used outdoors. They have a zinc coating thickness equal to about one-third that of Hot Dip Galvanised products.

Stainless Steel Grade 304

Grade 304 is a durable material, resistant to many corrosive elements, and is generally suitable for use in manufacturing applications. Products that are fabricated from Grade 304 are often specified to be used in brewing and dairy plants.

Stainless Steel Grade 316

Grade 316 is a member of the chromium nickel family of austenitic stainless steels, and contains an addition of 2% molybdenum for improved corrosion resistance. It is particularly resistant to corrosion in chloride environments. Grade 316 is used where corrosion resistance and long lasting service life is the primary concern in making a steel variety choice.

Some typical applications of Grade 316 are food and chemical manufacturing plants, marine environments and polluted atmospheres.

Zinc Plated Steel

Electro Zinc Plating is used on steel products to give them a coating of zinc. Unlike in galvanising, the zinc coating does not metalurgically bond with the steel, and the coating thickness is less than that found on galvanised coatings. It is however, a good option for fasteners or for smaller/intricate products. It offers an all over coating and has a smooth, shiny and clean appearance. 

Powder Coated Steel

Powder coating gives steel a coloured, strong but smooth and all over coating. It is a great option for colour coding/matching items, such as pipe clamps for different types of pipe or cable trays/ladders for organisation. However, it is also now becoming a popular choice for architectural work if a specific colour for the cable or pipe management services is considered important from a visual design point of view in a construction project.
