A Comprehensive Guide To Metal Fabrication Coating Types And Their Differences

At ABC Metalworks, we pride ourselves on providing top-quality metal fabrication services for a diverse range of industries. In this article, we discuss the different types of coatings available for metal fabrication, their unique characteristics and their respective applications.

Powder Coating: A Durable And Attractive Finish

Powder coating is a popular choice for metal fabrication projects due to its durability, environmentally-friendly nature and wide range of available colours. The process involves applying a dry powder, usually made of polyester, epoxy, or a blend of both, to the metal surface using electrostatic spray deposition. The coated metal is then cured in an oven, creating a strong and even finish.

Key Benefits Of Powder Coating

• Exceptional durability: Resistant to chipping, scratching and fading
• Environmentally friendly: Almost no VOC emissions and excess powder can be reused
• Versatile: Available in a vast range of colours and finishes, including gloss, matte and textured
• Corrosion resistance: Provides an extra layer of protection for metal components
• Galvanisation: Long-Lasting Corrosion Protection

Galvanisation is the process of applying a layer of zinc to steel or iron components to prevent rust and corrosion. This coating is achieved through hot-dip galvanising or electro-galvanising, depending on the desired thickness and application requirements.

Key Benefits Of Galvanisation

• Proven corrosion resistance: Protects the metal from rust and environmental factors
• Low maintenance: Requires minimal upkeep, saving time and money
• Longevity: Can last up to 50 years or more, depending on the environment
• 100% recyclable: Zinc and steel can both be recycled without losing their properties

Anodising: A Superior Finish For Aluminium Components

Anodising is a specialised electrochemical process that forms a protective oxide layer on aluminium surfaces. This process not only increases the metal's resistance to wear and corrosion but also allows for colouring and sealing.

Key Benefits Of Anodising

• Enhanced durability: Improves wear resistance and prevents corrosion
• Aesthetic appeal: Allows for colouring and various finishes
• Environmentally friendly: Produces less waste and fewer emissions than other coating methods
• Non-conductive: The anodised layer acts as an electrical insulator, preventing short circuits
  

Plating: A Versatile Coating Solution

Plating involves depositing a thin layer of metal onto a substrate, typically through electroplating or electroless plating. Common plating materials include gold, silver, nickel, and chrome, each offering unique properties for specific applications.

Key Benefits Of Plating

• Improved appearance: Provides a shiny, polished finish to metal surfaces
• Enhanced durability: Increases wear resistance and reduces the risk of corrosion
• Electrical conductivity: Can improve conductivity in electrical components
• Customisation: Offers a wide range of plating materials to suit specific needs
