UL 94 V0 FRP Cable Ladder Isophthalic Polyester 50mm-200mm Depth Pultruded

UL 94 V-0 FRP Cable Ladder for Data Center removes the two constraints steel ladders impose on a data hall: it conducts no current and it weighs roughly a quarter of galvanized steel. For overhead routes above live racks that combination means no bonding requirement, no risk of a dropped section bridging across a busway, and a ceiling structure carrying far less dead load.

The ladder is pultruded from E glass roving in an isophthalic or vinyl ester resin system with UV stabilizers and a fire retardant package, then assembled into rails and rungs with stainless fasteners. Widths span 50 mm to 1200 mm, rail heights 50 mm to 200 mm, rung pitch 225 mm, 300 mm or 450 mm, and support spans reach 1.5 m to 9 m depending on the load case.

Glass reinforced polyester does not rust, does not accept induced currents and is transparent to radio signals, which is why it is specified where WiFi, DAS or small cell antennas sit close to the cable route. Thermal conductivity is low, so the ladder does not act as a cold bridge in a chilled hall and condensate does not form on the rungs.

Fire behaviour is engineered rather than assumed. The resin package is formulated for low flame spread and low smoke emission, and the finished ladder remains non conductive even when wet, protecting maintenance staff working near energised equipment during fault finding or reconfiguration.

BENDIN pultrudes and assembles FRP ladder in house with 50000 m weekly capacity, three decades of composite and steel cable management experience and ISO 9001 controlled processes. 60 to 70 percent of output ships to overseas data centre, chemical and marine projects, and our engineers review each route for span, load and fire class before release to production.

Minimum order 100 m, 15 to 25 working day delivery, carton, box or wooden case packing, L/C, D/P or T/T terms, accessories included. Give us the load per metre, the support grid and the fire class required and we will return a sized ladder with spans, deflection and a complete fitting list.

BENDIN holds ISO 9001 quality certification and issues CE Declarations of Conformity. The standards above state the design and test basis of this product; third party test reports or national approvals are supplied on request and are not implied unless confirmed in the contract.

Dimensions, rung spacing and surface treatment are produced to project drawings. Load and deflection calculations are issued for spans above 3 m.

Q: Is the FRP ladder fire rated?
A: The resin package is formulated for low flame spread and low smoke, and we supply test data to ASTM E84 or EN 13501-1 so the fire class can be verified for the project.

Q: Does fiberglass need earthing?
A: No. The composite does not conduct, so no bonding is required. This is one reason it is chosen above live racks and near electrolytic equipment.

Q: How far apart can supports be?
A: Spans from 1.5 m to 9 m are achievable depending on cable load and rail height. We issue a deflection check for the specific load case.

Q: What is the minimum order?
A: Minimum order is 100 m with 15 to 25 working day delivery, packed in carton, box or wooden case on L/C, D/P or T/T terms.
