Laboratories

The main role of our in-house laboratory teams is, of course, to ensure our products are of a consistently high quality. Quality control experts inspect materials on arrival, and approve them before shipping to ensure that standards, material specifications and customer requirements have all been met. The results of these tests are fed back to the production team, enabling ongoing improvements to be made to our processes and products.

The second key area of their work is assisting our customers with any technical queries they may have. This is often done by carrying out analyses of samples, and by providing specific material data.
