Pultruded FRP Cable Ladder NEMA FG-1 Isophthalic Polyester UV Stabilized

FRP Cable Ladder NEMA FG-1 is the fibreglass ladder specified to the NEMA FG 1 designation used in North American projects: a pultruded composite route for corrosive and electrically sensitive areas where steel would need continuous inspection and where a conductive path is unacceptable.

The ladder is pultruded from E glass reinforcement in a fire retardant isophthalic polyester or vinyl ester resin, supplied in the characteristic green finish, with widths from 50 mm to 1200 mm, rail heights of 50 mm to 200 mm and rung pitch of 225 mm, 300 mm or 450 mm. Modules are 3 m or 6 m, with stainless fasteners at every joint.

NEMA FG 1 compliance is about performance rather than appearance: the section must carry its rated load at the specified span, resist flame spread, and remain non conductive. The pultruded profile achieves all three because the glass content is controlled through the die and the resin system is formulated for fire retardancy.

Composite construction removes the maintenance cost that dominates steel in a chemical plant: no repainting, no galvanizing repair, no rust staining on concrete, and no bonding or earthing required because the material does not conduct. It is also transparent to radio, which keeps wireless instrumentation working in the area.

BENDIN pultrudes and assembles FRP ladder at 10000 m per week with 180 staff and thirty years of cable support experience, exporting 60 to 70 percent of output to chemical, water and energy projects. Resin cure, rung pull out strength, colour and straightness are checked on every batch before packing.

Minimum order 100 m, 25 day delivery, 5 to 15 USD per metre, pallet packing, terms L/C, T/T or Western Union. Tell us the chemical exposure, the required load class and the span and we will confirm the resin system, rail height and rung pitch.

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: What does NEMA FG 1 require?
A: It covers fiberglass tray and ladder systems, including load performance, flame spread and non conductive behaviour, and we provide a submittal package for approval.

Q: Is the ladder non conductive when wet?
A: Yes. Resistivity is a property of the resin matrix and holds under wet contamination, which is why the route is used near live equipment.

Q: How is it cut on site?
A: With a diamond blade or carbide saw. The cut surface remains corrosion resistant because the material is homogeneous, so no coating repair is needed.

Q: What is the minimum order?
A: Minimum order 100 m, delivery 25 days, prices from 5 to 15 USD per metre.
