Reinforced Span Ladder Type Cable Tray Galvanized Steel 150mm-900mm Width Build

Long Span Cable Ladder Reinforced is the heavy section for routes that have to cross wide bays with few supports: turbine halls, mill buildings, hangars, warehouses and plant rooms where the structure provides hanger points at 4 m, 5 m or 6 m and the ladder has to carry a dense bundle between them.

The ladder is formed from galvanized steel, stainless steel or powder coated steel, with 150 mm to 900 mm width, 75 mm to 250 mm rail height, side rails of 1.5 mm to 3.0 mm and rungs of 2.5 mm to 5.0 mm at 225 mm, 300 mm or 450 mm pitch. Support spans reach 9 m with engineered brackets and a verified load case.

Reinforcement is achieved through the rail section and the connection detail: a deeper formed channel raises the moment of inertia, rungs are welded rather than clipped so the load path is continuous, and splice plates transfer bending moment at joints so a long run behaves as a continuous beam rather than a chain of short ones.

The ladder also has to perform under fire and fault conditions. The all steel construction is non combustible, the fire rated coating option meets BS 476, EN 1363 and IEC 60331 test protocols for circuit integrity, and the earthing path is maintained through couplers and bonding jumpers at every joint.

BENDIN produces this ladder at up to 50000 m per week with 180 staff and thirty years of heavy duty fabrication experience, exporting 60 to 70 percent of output to power, industrial and infrastructure contractors. Weld quality, coating thickness and dimensional accuracy are checked on every batch.

Minimum order 100 m, 15 to 25 working day delivery, 10 to 20 USD per metre, carton, box or wooden case packing, terms L/C, D/P or T/T. Send the span, the cable load and the fire requirement and we will return the rail height, the splice arrangement and the calculation package.

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.

• Turbine halls and power plant bays
• Steel mills and heavy manufacturing
• Warehouses and hangars
• Tunnels and large utility corridors
• Fire rated essential circuit routes

Q: How is a 9 m span achieved?
A: With a deep formed rail, welded rungs, moment transferring splice plates and engineered brackets, all supported by a project specific deflection calculation.

Q: What fire performance is available?
A: A fire rated coating system tested to BS 476 and EN 1363, with circuit integrity data to IEC 60331 for essential circuits.

Q: Is the earthing path continuous?
A: Yes. Couplers and bonding jumpers maintain continuity at every joint, and readings are recorded for handover.

Q: What is the minimum order?
A: Minimum order 100 m, delivery 15 to 25 working days, prices from 10 to 20 USD per metre.
