Fiberglass Cable Trays

Our perforated type Cable Tray provides reliable cable support in the corrosive application. Both Polyester & Vinyl ester resin systems are available & all components incorporating U.V. Stabilizer & a surfacing veil to resist corrosive atmosphere.

From power plants to fertilizer industries, paper mills to refineries to laboratories, the sound electrical design requires an adaptable cable support system that is reliable. Above all, durability & resistance to corrosion lead to lower costs during the life of the installation.

Corrosion resistance of resin system

Two standard composites resin system are available. For most of the application isopthlic Polyester fire retardant [FR-P] is widely used. A vinyl ester composites fire retardant resin system [FR-VE] is used where strong acid [ like hydrochloric acide] , strong alkalis [ Caustic Soda], organic solvent and halogenated organic conditions exits. Sumip fiberglass cable tray incorporates a synthetic veil on the surface of all structural shapes which causes a resin rich layer which enhances corrosion protection. A abbreviated guide can be provided on request to assist in the selection of the proper resin system for individual application.
