From design through to manufacture and sales Manthorpe Building Products is an ambitious and dynamic company with over 30 years of experience within the building products industry.

Established in 1986, as part of the Manthorpe Group, Manthorpe Building Products allowed the company to branch out its manufacturing knowledge and experience into the area of plastic injection moulding, vacuum forming and extrusion. From its humble beginnings Manthorpe Building Products is now an ambitious and dynamic company in its own right producing its own range of market leading products for the building industry with particular emphasis on domestic new build. From design to sales we are very proud of our investment in new manufacturing equipment and staff, continually striving to improve every aspect of our business.

With over 30 years experience in the plastics industry we manufacture virtually all our products in-house and in recent years we have invested extensively in technology and cutting edge machinery. Using modern manufacturing processes we injection mould, extrude and vacuum form to a high standard. Our product portfolio is comprehensive and product development is ongoing through our in-house R&D Department and our state of the art IT systems help to support and grow every aspect of our business.
