Hot Zinc Metal Spraying

Our Thermal Spraying Services

Hot zinc thermal spraying is being increasingly used as an alternative to the hot dipped galvanizing process

Thermal Spraying is not a new process. It has proved itself to be extremely effective in the 90 years of its existence in all manner of applications ranging from coatings in gas turbines to corrosion protection on park benches.

Unsurpassed protective system

As a protective system for structural steelwork it is unsurpassed being the only system, recommended by International and European standards EN ISO 14713 as giving greater than 20 years to first maintenance in very aggressive environments such the marine splash zone (category lm2) as well as all other categories.

Anti-Corrosive Coatings

Metal or thermal spraying is a technology, which protects and greatly extends the life of a wide variety of products in the most hostile environments and in situations where coatings are vital for longevity. The variety of metallised coatings is vast but can be broken down into two main categories. These include finishing coatings, such as anti corrosion or decorative coatings.

Metal spraying

Metal spraying is a very flexible process. The range or materials that can be sprayed is almost limitless. The range of applications that Hot Zinc Spray can be used for has mainly developed because of the limitations of hot dip galvanising, as many items are too large for the average hot-dip galvanising also the side effects of heat transfer and potential distortion.

Metal spraying is carried out in a wide range of anti-corrosion and engineering markets, including oil and gas, construction, petrochemical and marine. Corrosion is a major problem for these industries.


This is a very short summary of a virtually endless list of applications.:

  • Balustrading / Balconies
  • Structural Steelwork
  • Gates / Railings
  • Architectural Fabrications
  • Bridges / Platforms
  • Chassis & Components
