Industrial Plant Ladder Cable Tray Long Span Hot Dip Galvanized ISO 1461 900mm Width

Long Span cable ladder for Industrial Plants is engineered for the long straight runs that dominate heavy industry: from the main substation down a pipe rack, across a mill bay or along a tunnel wall, where support points are far apart and the ladder has to carry dense feeder bundles without visible sag between hangers.

The section uses S235JR or S275JR steel rails of 2.5 mm to 3.0 mm with 100 mm to 150 mm height, welded rungs at 225 mm or 300 mm pitch, and 3 m or 6 m lengths that reduce the number of joints on a long run. The deep rail is what delivers the moment of inertia needed when support spacing stretches to 4 m, 5 m or 6 m.

Hot dip galvanizing to ISO 1461 after fabrication coats the inside of the rail profile as well as the outside, so a plant atmosphere with sulphur, dust and humidity does not attack the section from within. Zinc thickness of 65 to 85 micrometres gives a maintenance free life well beyond the usual refurbishment cycle of a production line.

For spans beyond the standard tables we issue a project specific calculation: cable load, ladder self weight, wind and seismic case, allowable deflection of span over 200, and the resulting hanger schedule. Bends, tees, expansion joints and sliding supports are supplied so thermal movement along a long route does not load the structure.

BENDIN fabricates 20000 m of this ladder per week with 180 staff and thirty years of heavy duty cable route experience, exporting 60 to 70 percent to construction, power and industrial contractors. Each order is dimensionally checked against the approved drawing and the coating is gauge tested before dispatch.

Minimum order 100 m, delivery 5 to 30 days by size, 2 to 50 USD per metre, packing in pallet or bulk, terms L/C, D/P, T/T, D/A. Share the route drawing and cable weights and we will return hanger spacing, expansion joint positions and a full material take off.

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.

• Steel mills, cement and heavy manufacturing bays
• Pipe racks and tank farms
• Power plant and substation main runs
• Tunnels, conveyor galleries and utility corridors
• Mining and material handling plants

Q: How do you justify a 6 m support span?
A: We calculate cable load, self weight, wind and seismic cases against an allowable deflection of span over 200, then issue the hanger schedule and splice details for approval.

Q: Are expansion joints needed on long runs?
A: Yes. On exposed runs we supply expansion joints and sliding supports so thermal movement does not buckle the ladder or load the anchors.

Q: What coating is used?
A: Hot dip galvanizing to ISO 1461 after fabrication, typically 65-85 um, with a duplex powder coat option for C5 atmospheres.

Q: What is the minimum order?
A: Minimum order is 100 m, delivery 5 to 30 days by size, prices from 2 to 50 USD per metre.
