Since then, the company has evolved to undertake challenges in a range of industries to become a leading manufacturer of high quality tension lorry curtains, since the product was first invented. The company has continued to provide an increasing range of innovative technical products for the commercial vehicle industry as well as wide-format digital printing, proof load test bags for weight-bearing equipment such as cranes, and air lift bags for the diving industry.
