Cable trays – fiberglass

GRP CABLE TRAYS (GRP – CFRP), reinforced with fibreglass and/or carbon, represent one of the pultruded profiles made by Top Glass.
These composite products are designed and manufactured to meet stringent technical requirements with regard to mechanical properties and fire resistance.

The main advantage of these types of cable trays and ladders are their excellent electrical insulation (does not require grounding) and their fire behaviour (self extinguishing with an absence of toxic fumes).
They are extensively used for the installation and protection of cables inside tunnels and wherever higher safety standards are required.
