The Truth About Marine Grade Powder Coating for Roller Shutters: What You Really Need to Know

 

The term “marine grade powder coating” is widely used in the construction and security shutter industry, but it can be misleading. In reality, there is no special or separate “marine grade” powder coating product available in the UK. Instead, the durability and corrosion resistance associated with marine environments are achieved by applying powder coating to a specific thickness and ensuring the process meets established British Standards.

The Key: Powder Coating Thickness

For a powder coated finish to be suitable for marine or coastal environments, the most important factor is the thickness of the coating. According to industry best practice and British Standards, the coating should be applied to a thickness of between 80 and 120 microns (μm). This level of coverage provides the necessary protection against salt, moisture, and harsh weather conditions found in marine and coastal locations.

- 80–120 microns: The recognised standard for corrosion resistance in challenging environments
- Consistent application: Ensures longevity, colour retention, and protection for aluminium and steel shutters

British Standards Guarantee Marine-Ready Protection

Any reputable UK powder coater working to the relevant British Standards—such as BS EN 12206-1 for aluminium or BS EN 13438 for galvanised steel—will automatically apply powder coating within the 80–120 micron range. This means that, as long as your roller shutters or doors are finished by a certified powder coater, you’re getting a finish that meets or exceeds what’s often marketed as “marine grade.”

Key British Standards for Powder Coating:
- BS EN 12206-1: Powder coatings for aluminium
- BS EN 13438: Powder coatings for galvanised steel
- BS 6496 & 6497: Architectural powder coatings for aluminium and steel

- No need for “special” marine grade powder: Simply ensure your supplier uses a qualified powder coater who works to British Standards.
- Ask for certification: Reputable manufacturers, like HVP Security Shutters, always provide documentation showing compliance with the relevant BS standards.
- Peace of mind: Your shutters and doors will be protected for years to come—even in demanding marine or industrial environments.
