With a reputation for innovation, quality and responsiveness, HL Plastics is one of the UK’s leading PVCu extrusion companies. Its premises consist of a purpose-built extrusion plant, warehouse and offices in Denby, Derbyshire, together with one of the biggest PVCu mixing plants in Europe.

A workforce of over 400 keeps HL Plastics’ operations running throughout the year, and the company has a history of developing young talent; offering apprenticeships and promoting from within wherever possible.

The Liniar brand was created by HL Plastics, with the range consisting of three distinctly different types of product serving different markets:

  • Window, door and conservatory fabricators and installers
  • Caravan owners, holiday parks and gardeners
  • Construction, waterways, retention and flood prevention

Prime Minister David Cameron visited the factory in 2014 to host a PM Direct session with 150 of the workforce, praising the company for its growth in the manufacturing sector.

The Flamstead Group was featured in the London Stock Exchange’s inaugural 2013 book: “1,000 Companies to Inspire Britain” and was included again in the second, 2015 edition.
