Weatherproof Cable Ladder 450mm Width ISO 1461 Hot Dip for Outdoor Installation

Outdoor Cable Ladder Weatherproof is the 450 mm eighteen inch route built for roofs, yards, car parks and coastal walkways, where rain, UV, frost and wind driven salt attack the support system long before the cable reaches its service life. The open rung design drains freely, so water never stands in the tray and ice does not split a coated surface.

Rails are S235JR steel with 2.5 mm wall and 100 mm or 150 mm height, hot dip galvanized to ISO 1461 after cutting and welding, in 3 m and 6 m lengths. Because the zinc is applied after fabrication, every drilled hole and sheared edge is protected, which is exactly where a painted ladder fails first on an outdoor route.

The 450 mm width carries mixed power and control bundles on a single route and still allows a two person lift onto a roof frame. Rung pitch of 225 mm or 300 mm keeps cable supported at regular intervals, and matching bends, tees and wall brackets mean the route can follow a parapet, drop down a riser and cross a plant room without on site welding.

For long outdoor runs we include expansion provisions and sliding supports so thermal movement between winter and summer does not buckle the ladder or load the anchors. Earthing continuity is maintained through couplers and bonding jumpers at every joint, which the standard requires and which inspectors check.

BENDIN runs its own galvanizing line and fabricates 10000 m weekly with 180 staff, exporting 60 to 70 percent of output to construction and infrastructure contractors. Thirty years of outdoor cable route work sit behind our coating control, and every batch is checked for zinc thickness, adhesion and straightness before shipping.

Minimum order 100 m, delivery 10 to 25 days, prices from 10 to 60 USD per metre, pallet or bulk packing, terms L/C, D/P, T/T or Western Union. Send the roof layout and the local corrosivity class and we will confirm coating system, anchor spacing and expansion joint positions.

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: How does the ladder handle standing water and ice?
A: The open rung design drains freely, so water does not pool in the tray and ice cannot split a coating. Post fabrication galvanizing also protects the drilled holes and sheared edges.

Q: What coating class suits a coastal roof?
A: For C4 and C5-M exposures we supply a duplex system, powder coat over hot dip galvanizing, with stainless fasteners and isolating washers.

Q: Are expansion provisions included?
A: On long exposed runs we supply expansion joints and sliding supports so thermal movement between seasons does not load the anchors.

Q: What is the minimum order and lead time?
A: Minimum order 100 m, delivery 10 to 25 days, prices from 10 to 60 USD per metre.
