Quality Guaranteed

The plugs we sell are made from polyethylene which offers universal appeal and a number of application possibilities. Polyethylene is known for its low abrasion and resistance to corrosion from environmental stress. It’s also got high dimensional stability at low temperatures, good chemical resistance, low water absorption and is resistant to changing weather conditions and UV radiation.

A Variety of Uses

Our rectangular plastic end caps have been designed and tested to accommodate steel profile structures, steel tubing, pipes, and box sections, hollow section, tubes, chair legs, chair foot, bench foot, fencing systems, some machines and devices, workshop furniture, playground equipment and other elements of garden architecture. They are used in the furniture, machinery, electrical engineering and construction industries.
