Over the years the type of products and the materials used, have changed in order to keep up with our customers' requests and market conditions. From 1976 on, Hinspergers (HPI) have been supplying a huge range of protective covers made from woven and extrusion coated polyethylene. Due to the tremendous strength, reduced weight, wide color range and relatively low prices, the fabric is now used worldwide in industry, agriculture, construction and consumer products.
