FRP Cable Trays

Ladder & Perforated type Cable Tray provides reliable cable support in corrosive application. Both Polyester & Vinyl ester resin systems are available & all components incorporating U.V. Stabilizer & a surfacing veil to resist corrosive atmosphere. Above all durability & resistance to corrosion lead to lower costs during the life of installation.

Features

• Corrosion resistance
• Strength & durability
• Fire Redundant
• U.V. Stabilized

Applications

• Chemical Plants
• Power Plants
• Effluent Treatment Plants
• Offshore Platforms
• Paper Plants
• Refineries

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 acid ] , strong alkalies [ 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.
