Where the application or specification demands, glass reinforced plastic can be applied to PVC ductwork with a chemical etching process and in the case of Polypropylene a special fabric backed version is available to ensure mechanical bonding. We have the design experience and technical knowledge to cater for all types of application, including exhaust stacks and structure subject to wind loading calculations.
Fabricated from any combination of plastics but usually PVC, Polypropylene and supplied with or without Fibre Glass Reinforcement.
We offer a very quick turn around on all fabricated ductwork transitions, from simple spigot adapters to square to rounds, special reducers etc.
All production information is kept on digital files so that should you ever need to know a specific bolt hole, or require an identical / replacement we can confirm or start production without any delay.
