Construction Products
UB Plastics supplies specialist injection moulded components to support a wide range of construction systems, from cladding and balcony assemblies to general-purpose site or structural applications. Our parts are designed to meet practical performance requirements while also supporting safety, ease of installation and a clean, finished appearance.
Working closely with construction product manufacturers, we produce durable, high-quality mouldings that hold up to the demands of real-world use. Whether it’s an end cap for installer safety, a spacer to improve assembly, or a functional detail in a building system, each component is manufactured with precision and consistency at scale.
All production takes place at our UK site in Burton upon Trent, with support available from design through to delivery.
