Quality goes without saying at Staco. We place high demands on our gratings, stair treads and associated products, and you our customer naturally do the same. We also strive to optimise the price-quality ratio. We have ISO 9001 certification: our quality-assurance system complies with internationally recognised standards and is assessed annually. In addition, all our gratings and stair treads have the CE quality mark. So you can rest assured that Staco products comply with the strictest European directives and regulations and may be used in any European country. Moreover, Staco is the first grating manufacturer with the cradle-to-cradle certificate.
