Now Tier 1 Supplier to Network Rail

BCM GRC Ltd are now a Tier 1 supplier to Network Rail under Agreement No: 5847/01/386

BCM GRC Ltd have been supplying Network Rail and London Underground with troughing for signalling, communications and power for over 20 years and during this time have worked in conjunction with rail industry design engineers to develop the current fully approved system. The BCM GRC Ltd cable channel system includes all the channels, lids, stakes, brackets and accessories that are required on a modern railway network.

During the period 2009 to 2011 BCM GRC Ltd worked alongside senior Network Rail personnel to comprehensively upgrade our elevated systems overcoming issues that have been affecting E&P and S&T for a number of years. Issues such as finger trapping, lid “popping” and troughes dropping between posts where all discussed and dealt with.

This extensive upgrade has seen the BCM GRC Ltd system gain widespread acceptance by those who have used it.

In addition to offering a product that is easily installed and maintained, GRC is a material which has distinct advantages over other materials.
