What are the different types of sheet metal finishing and coatings?

Havant Sheet Metal specialises in transforming raw metalwork with custom surface coatings and finishes to amplify not only their durability, but aesthetic appeal too. As experts in transformative finishing options for metal, we have put together a definitive guide to the different finishes for metal. 

Want to know which coating will protect metal from rust, which paint won’t peel off metal, what the most durable coating for metal is or which finish is best suited for the marine industry? Read on to discover exactly what they are and which coating may suit your requirements.

Powder Coating for Sheet Metal 

Can you powder coat metal yourself?

The short answer is yes, but the long answer is that it requires a lot of specialist equipment, preparation and care. We’d recommend using a professional and experienced powder coating metal service provider to ensure the best results that last and are guaranteed. 

What are the benefits of powder coating?

• Exceptional Corrosion Protection: Powder coating on metal forms a durable barrier against moisture and chemicals, helping prevent wear in demanding environments, which we have found especially beneficial for the marine industry.
  
  

• Outstanding Durability: Engineered to resist chipping, scratching and fading, delivering a tough, long-lasting finish.
  
  

• Design Versatility: Powder coating is available in a wide range of colours and finishes and textures including matte, gloss, metallic, providing customisation options beyond traditional stainless steel.
  
  

• Low Maintenance & Environmentally Responsible: Easy to clean and maintain, with a coating process that is typically more eco-friendly than solvent-based alternatives.
  
  

• Structural Longevity: Powder coating helps extend the service life of components, minimising repair and the need for replacement.

Are there any downsides to powder coating metal?

If powder coating is done without adequate preparation or curing, discolouration, poor adhesion and warping of the metal component can occur. This is why we always recommend using an experienced provider of powder coating to ensure the best results. 

How long does powder coating on metal typically last?

When proper surface preparation, professional application and routine maintenance are followed, powder coating on metal can provide durable protection for up to 40 years.

What application is powder coating for metal best used for?

As powder coating creates a highly durable and weather resistant coating, it is ideal for protecting steel and aluminium in a range of applications and industries including defence, aerospace and marine equipment and components, pharmaceutical parts, industrial machinery and a range of electronics parts.

Wet Spray for Sheet Metal

Can you spray paint metal yourself?

You can, but using a skilled company with advanced equipment and experienced operatives will offer much more durable and consistent results that will last longer and give a superior finish.

What are the benefits of wet spray on metal?

• High-Quality Finish: Delivers a smooth, uniform and consistent surface, free from brush marks, with the flexibility to apply ultra-thin or heavier coatings as required for your project.
  
  

• Ideal for Complex Shapes: Perfect for large, intricate or irregular shapes and for materials that cannot tolerate the high temperatures of powder coating.
  
  

• Rust Protection: Forms a durable barrier against moisture, rust and chemical exposure.
  
  

• Cost-Effective & Customisable: Often more economical for smaller production runs, with a broad and precise range of colours, finishes, designs and textures available.
  
  

• Thorough Coverage: Effectively penetrates edges and crevices to ensure complete coverage.
  
  

• Flexible Curing Options: Can be air-dried or oven-baked, providing flexibility within different production schedules.

Are there any downsides to spray painting metal?

Wet spray painting is generally less durable than powder coating alternatives. Wet spray is also less eco friendly due to the high levels of VOCs in the paint and wet spray wastage due to overspray. Wet spray also takes longer to dry and cure compared to powder coating and the need for multiple coats increases lead times and sometimes, cost. 

How long does spray painted metal usually last?

When sufficient preparation and optimum adhesion has been achieved, wet spray paint on metal can last for up to 10 years. With poor prep, the lifespan can be as little as 1 month in an outdoor environment. 

What application is spray painting for metal best used for?

Wet spray paint on metal is generally recommended for:

• Large and heavy items

• Heat sensitive materials

• When intricate or custom designs are required

• Complex shapes with nooks and crevices

• Furniture and architectural items for indoor use such as railings and furniture 

• Automotive machinery and car parts 

• On-site applications

Stove Enamel Coating for Metal

What are the benefits of stove enamelling?

• Exceptional Durability: As the enamel is fused to the metal through high-temperature curing, this results in a strong, resilient finishing option.
  
  

• Creative: A wide range of colour and finishes allow for versatile results that can be customised to enhance the visual appearance of metal. When design and aesthetic appeal is crucial, stove enameling is the best choice.
  
  

• Environmental Protection: The enamel coating creates an effective barrier from rust, chemicals and preserves the structural integrity of components.
  
  

• Eco Friendly: Unlike some stove enamel applicators, here at HSM, we prioritise using low VOC enamel formulations and our curing process uses high temperatures opposed to chemical catalysts. We have taken these steps as part of our mission to minimise our carbon footprint while still delivering superior results. 

Are there any downsides to stove enamelling?

Stove enamelling can be susceptible to chipping as it is essentially a glass coating. While the coating is heat resistant, it is sensitive to rapid changes in temperature which can cause the enamel to crack. 

How long does stove enamel finishing last for?

Stove enamelling is very durable and can last for decades or even a lifetime, making it a cost effective choice for many applications. 

What application is spray painting for metal best used for?

Stove enamelling can be used for a wide range of applications including appliances, architectural features and automotive parts.
