• Available in a range of colours and textures
• Able to provide extended durability for steel.

Where to get a duplex coating

Whilst we do not offer duplex coatings from our Widnes plant, our sister Joseph Ash Medway plant offers a 40-year guarantee on duplex coatings (subject to T&Cs). They also offer a wide variety of durable powder coating finishes from metallic to textured, in a huge range of bright colours with varying matt, satin and gloss levels.
