GLS 100R® is the PROVEN solution when complete electrical insulation protection is needed.GLS100R

As a Network Rail Approved Supplier, GLS Coatings' PTS-trained technicians, using self-contained mobile coating rigs, can coat and encapsulate ANY steelwork – whether it is the metal railings surrounding a sub-station, or the steelwork of a pole-mounted distribution transformer

Since our successful initial project, when we coated all the Signalling Location Cases in the public domain for Wessex Route, through to our collaboration with Network Rail and Southampton University, ONLY our GLS 100R® is providing the solution to the many diverse problems.

Increasingly, Network Rail Routes are encountering problems when the clearance between the OLE and the substrate of the bridges is significantly reduced. We have worked with Richard Stainton, Professional Head of Electrification at Network Rail, and Southampton University, in testing our GLS 100R® at 195kV in both AC and DC currents, in conjunction with surge protectors, to provide a solution.

ONLY GLS 100R® - insulates up to 35,000 Volts.


GLS100R® is the long term cost effective guaranteed solution and offers the following benefits:

  • Insulates steelwork up to 35,000 Volts
  • Insulates against the risk of touch-potentia
  • Network Rail approved
  • TOUCH-DRY in UNDER 10 SECONDS

From start to finish GLS Coatings’ Projects have complete traceability through our bespoke iPad Digital Reporting System

GLS Coatings Ltd are the ONLY Approved Framework Supplier to Network Rail for the application of Electrically Insulating Coatings.

Faster return to service

Our rail coatings provide a fast return to service, allowing work to be completed during off peak hours.

GLS 100R® coatings are applied by our PTS trained technicians. GLS Coatings’ mobile rigs include a spray machine, a portable generator and an air-compressor. Completing the kit is a collapsible spray-tent, with GRP mechanics. This ensures it complies with Network Rail’s safety requirements.

Case Study

Wessex Routes

Wessex Routes have insulated ALL of their Location Cases covered by the ORR Notice I/20121220/JSM (SIN 119)

Using the GLS 100R® Coating, which is certified by ERA Technologies, (developed jointly with FT Transformers and GLS Coatings Ltd), we were able to coat the Location Cases from Waterloo to Southampton while they were still ‘live’, meaning there was no interruption to the network.

GLS Coatings Technicians, with their fully mobile, self-contained spray units, travelled over 1,000 miles in two weeks to prepare and insulate ALL of the platform-sited Location Cases to over 35,000 Volts.

Using top-of-the range coating units, complete with generators and compressors, our PTS-trained Technicians tackled the diversity of the work head-on. From Locs under stairs at Waterloo to some set into embankments on the more rural stations, the work was completed in just TWO WEEKS.
