Powder Coating

At Alini Metals & Plastics, we’re passionate about providing long-lasting, beautiful finishes for all your metalwork and custom projects. We are proud to offer a high-quality powder coating service, delivering a durable and aesthetically pleasing finish to a wide variety of metals and materials. Powder coating is a process that provides a robust, weather-resistant coating, enhancing both the appearance and the longevity of the product. Whether you’re working on an architectural masterpiece, an industrial project, or something more personal, powder coating is a perfect way to protect and enhance your materials.

What is Powder Coating?

Powder coating is a method of applying a protective, decorative finish to metals and other materials. Unlike traditional liquid paint, powder coating uses a finely ground, dry powder made from resin, pigments, and specialised additives. The powder is applied electrostatically, meaning it is charged with electricity and sprayed onto the surface of your metal. Because the metal is grounded, the powder sticks to it evenly. Once applied, the coated material is baked in a curing oven, where the powder melts and forms a smooth, solid layer. This creates a durable, tough finish that’s both beautiful and long-lasting.

The Powder Coating Process

When you choose powder coating at Alini Metals & Plastics, you’re not just getting a colour – you’re getting a process that’s designed to stand the test of time. Here’s what happens step by step:

Surface Preparation: Before applying the powder, the surface of the metal is carefully cleaned and pre-treated. This ensures any oils, rust, or contaminants are removed, allowing the powder to bond effectively to the material.
Application of the Powder: Using advanced electrostatic spraying equipment, we apply the powder to the metal’s surface. The charged powder particles are attracted to the metal, coating it evenly.
Curing: The coated metal is then placed in a specialised curing oven. As the powder heats up, it melts and chemically bonds to the surface, forming a tough and protective layer.
Final Inspection: Every piece is thoroughly checked to ensure the finish is perfect, uniform, and meets the high standards we uphold.

What Materials Can Be Powder Coated?

Our powder coating service is versatile enough to be applied to a variety of materials, including:

Aluminium and steel for architectural and construction applications.
Stainless steel, which is often used in furniture, railings, and decorative metalwork.
Copper and brass for more specialised finishes, often seen in bespoke projects.
Non-metallic surfaces such as plastics and composites can also be powder coated, expanding the possibilities for your designs.

Vast Colour Range

We understand that aesthetics are just as important as functionality, which is why we offer powder coating in any colour from the RAL colour chart, giving you limitless possibilities to match your project’s design. From classic neutrals to bold, bright shades, we have the perfect colour to meet your specifications. The powder coating process ensures that the colour is evenly distributed and remains vibrant for years, even in demanding outdoor environments.

Thickness and Lifespan of Powder Coating

Powder coating offers not only visual appeal but also serious durability. The thickness of the powder coating layer is typically between 60 to 80 microns (0.06 to 0.08 mm), though we can adjust this based on the specific requirements of your project. This thickness is more than enough to provide a tough barrier against wear and tear, corrosion, and the elements.

When properly applied and maintained, powder coating can last up to 20 years or more, making it one of the most durable finishes available. It offers excellent protection from UV rays, weathering, and chipping, and it’s far less likely to fade or degrade over time compared to traditional paint finishes.

Customisation and Finishes

One of the most exciting aspects of powder coating is the vast array of customisation options we offer. We can create any colour you desire, thanks to our extensive selection from the RAL colour chart. Whether you need a sleek, modern black or a bold, eye-catching red, we’ve got you covered.

To further tailor the look of your final coating, we offer three distinct finishes:

Matte: A smooth, understated look that offers a soft, non-reflective surface.
Satin: Slightly shinier than matte, this offers a delicate sheen that strikes a balance between gloss and matte.
Gloss: For those looking for a striking finish, our gloss option creates a highly reflective surface that adds a polished, premium look to any material.

Industries and Applications

Powder coating is widely used across many industries thanks to its durability and flexibility:

Architectural: Powder-coated metal is a favourite for cladding, façades, and window frames, offering both protection and a modern, sleek finish.
Construction: It provides excellent corrosion resistance, making it perfect for external metal structures such as fences, gates, and railings.
Automotive: It’s commonly used for vehicle parts and accessories, providing a tough, durable coating that stands up to road wear.
Interior Design: From furniture to fixtures, powder coating can add a vibrant and durable finish to your design projects.

Technical Information

For those who need the technical details, our powder coating process is compatible with most industry-standard materials. The powders we use are primarily composed of epoxy, polyester, or hybrid resins, each providing specific properties depending on your project’s needs:

Epoxy-based powders: Ideal for interior applications due to their toughness and chemical resistance.
Polyester-based powders: Perfect for outdoor applications, offering superior resistance to UV rays and weathering.
Hybrid powders: A combination of epoxy and polyester for a balance of strength and flexibility.

Each finish is applied with precision to meet your aesthetic requirements while maintaining the coating’s durability and protective qualities.
