We chose to work closely with Sigma EPD on various projects due to their highly efficient service and high quality products supplied. We procured on numerous occasions security/anti-vandal louvers which were to a high specification, the louvers were fitted in prisons, supermarkets, public buildings etc.

These louvers were supplied in various sizes and colours and our clients were impressed with the quality and service supplied by ourselves via Sigma EPD.

I am pleased to be associated with Sigma EPD and would have no problems in recommending/using them on future projects.
