Cable Tray Cost Estimation, BOQ Preparation and Procurement Guide in Saudi Arabia

Author : Hitech Fence | Published On : 29 Oct 2026

Introduction

Electrical infrastructure projects require accurate material planning to support organized cable distribution and efficient installation.

Across Saudi Arabia, industrial facilities, commercial buildings, oil and gas plants, and infrastructure developments use cable management systems to support power and communication networks.

One commonly used solution is the cable tray, which provides a structured pathway for electrical cables.

However, preparing an accurate cable tray quotation involves more than calculating the total length of straight trays.

Engineers and cost estimators must consider tray dimensions, material thickness, protective coatings, fittings, supporting brackets, and installation requirements.

Incomplete quantities or unclear specifications can lead to additional procurement costs and construction delays.

This guide explains cable tray cost estimation, BOQ preparation, material selection, and supplier evaluation for electrical projects in Saudi Arabia.

1. What Is a Cable Tray System?

A cable tray is a structural support system designed to carry and organize insulated electrical and communication cables.

It provides an accessible pathway for cable routing in industrial and commercial installations.

Cable trays are available in several configurations, including perforated trays, ladder trays, wire mesh trays, and cable trunking.

Contractors looking for a suitable cable tray should evaluate the complete system rather than purchasing straight sections alone.

Common Cable Tray Applications

  • Industrial manufacturing facilities.

  • Oil and gas installations.

  • Electrical substations.

  • Commercial buildings.

  • Data centers.

  • Warehouses and logistics facilities.

  • Infrastructure and utility projects.

The correct system should be selected according to the project's electrical design, load requirements, and environmental conditions.

2. Why Cable Tray Cost Estimation Matters

Accurate cost estimation helps contractors prepare realistic project budgets and purchasing schedules.

Cable tray systems include several material categories that can influence the final project cost.

For example, two cable tray systems with the same overall length may have different costs because of their widths, material thicknesses, protective finishes, and accessory requirements.

Main Cost Factors

Material Type: Steel grade and manufacturing requirements influence cost.

Tray Dimensions: Width, height, and thickness affect material consumption.

Protective Finish: Pre-galvanized, hot-dip galvanized, and powder-coated options may have different manufacturing costs.

Accessories: Bends, tees, risers, and couplers add to the material scope.

Supporting Components: Brackets, hangers, and anchors require separate consideration.

Delivery: Transportation and packaging requirements affect the overall quotation.

A detailed BOQ helps contractors identify these items before placing orders.

3. Understanding Cable Tray Dimensions

Cable trays are manufactured in different sizes to accommodate varying cable quantities and structural requirements.

Hitech Fence's main cable tray product range includes widths from approximately 50 mm to 1,000 mm and material thicknesses from 1.2 mm to 3.0 mm.

Individual products may have different size ranges.

Important Dimensions

Width: Determines the available cable routing space.

Side Height: Helps define the tray's section geometry and accommodation of cable arrangements.

Material Thickness: Influences structural characteristics and material consumption.

Standard Length: Determines the number of straight sections required.

Support Span: Influences structural loading and must follow the approved design.

Contractors should confirm these dimensions through technical datasheets and approved project drawings.

4. How to Calculate Straight Cable Tray Quantities

The first stage of quantity estimation involves determining the actual cable tray routes.

Engineers should review approved electrical layouts and identify each route's length, dimensions, and installation elevation.

For straight sections, a preliminary calculation can be made using:

Required Straight Pieces = Total Straight-Run Length ÷ Standard Piece Length

Example Calculation

Consider a project requiring 300 meters of straight cable tray.

If the selected standard tray length is 3 meters:

300 ÷ 3 = 100 pieces.

Therefore, the preliminary requirement is 100 straight tray pieces.

However, this calculation assumes a total straight-run length of 300 meters.

Actual procurement quantities must consider fittings, route changes, special pieces, cutting allowances, and manufacturer dimensions.

The final quantity should be established from the approved routing schedule.

5. Estimating Cable Tray Accessories

Accessories are important components of cable management installations.

They accommodate directional changes, vertical transitions, and connections between straight sections.

Common Accessories

  • Horizontal bends.

  • Vertical inside risers.

  • Vertical outside risers.

  • Tee fittings.

  • Cross fittings.

  • Reducers.

  • Straight couplers.

  • End plates.

  • Covers where specified.

  • Connecting bolts and fasteners.

Each accessory should be counted according to the cable tray layout.

For example, a routing plan involving several changes in direction may require multiple horizontal bends.

The required dimensions and protective finishes should match the adjoining tray sections.

Accurate accessory estimation reduces the risk of missing materials during installation.

6. Ladder Cable Tray Cost Considerations

Ladder cable trays use longitudinal side rails connected by transverse rungs.

These systems provide an open structure suitable for specified cable loads and industrial applications.

Hitech Fence offers ladder cable tray systems in light-, medium-, and heavy-duty configurations.

Its published range includes widths from 50 mm to 900 mm and sheet thicknesses from 1 mm to 2 mm.

Important Cost Considerations

Load Rating: The selected configuration must satisfy the required cable loads.

Rung Arrangement: Different structural configurations can affect manufacturing requirements.

Material Thickness: Influences material consumption.

Protective Coating: Must suit the project environment.

Supporting Span: Affects the support system design and quantities.

Fittings: Bends, risers, tees, and crosses require separate pricing.

Cost estimation should reflect the approved structural configuration rather than assuming all ladder trays have the same load capacity.

7. Cable Tray Supporting Systems and Cost

Supporting components are sometimes overlooked during early material estimation.

However, a complete cable tray installation requires suitable structural support.

Common Supporting Arrangements

Wall Brackets: Used for trays installed along suitable walls or structural members.

Cantilever Arms: Provide support from an approved structure.

Trapeze Supports: Use suspended arrangements to support trays below ceilings or structures.

Threaded Rods: May be used with suitable suspended support assemblies.

Anchors and Fasteners: Secure supporting components to approved structures.

Support quantities depend on the installation layout, permissible spans, cable loads, and structural design.

Estimators should avoid applying a universal support spacing without manufacturer load information.

8. Galvanized Cable Tray Pricing Factors

Protective coatings influence both initial cost and long-term maintenance considerations.

Saudi Arabia includes inland, coastal, and industrial environments with different corrosion exposure conditions.

Common Coating Options

Pre-Galvanized Steel

Manufactured from previously zinc-coated sheet material and commonly considered for suitable indoor environments.

Hot-Dip Galvanized Steel

Suitable fabricated steel components receive zinc coating after fabrication, providing protection on accessible surfaces.

Powder-Coated Steel

An organic coating provides a decorative and protective finish when properly specified and applied.

Selection should reflect the approved project requirements.

Contractors should not compare material prices without confirming that the proposed finishes offer the required protection.

9. Preparing a Detailed Cable Tray BOQ

A complete Bill of Quantities should separate the different material categories.

This helps suppliers prepare accurate quotations and allows procurement teams to compare proposals consistently.

Recommended BOQ Format

Item Description Unit
1 Straight cable tray sections m / pcs
2 Horizontal bends pcs
3 Vertical risers pcs
4 Tee fittings pcs
5 Cross fittings pcs
6 Reducers pcs
7 Straight couplers sets
8 Supporting brackets pcs
9 Threaded rods and hangers sets
10 Covers where required m / pcs
11 Fasteners and accessories sets

The BOQ should also identify the tray type, width, height, thickness, protective finish, and applicable specifications.

Consistent measurement units are important for accurate supplier comparisons.

10. Common Cable Tray Estimation Mistakes

Several mistakes can affect cable tray procurement.

Common Errors

Incorrect Dimensions: Ordering the wrong tray width or height can create installation problems.

Missing Fittings: Bends, tees, and risers may be overlooked.

Incomplete Supports: Brackets and hangers may not be included.

Wrong Coating: A finish may not meet the environmental requirements.

Unverified Loading: Tray dimensions alone do not establish load capacity.

Duplicate Quantities: Fittings and straight-route lengths may be counted incorrectly.

Incomplete Delivery Scope: Transportation and unloading may be excluded.

These problems can be reduced through careful drawing reviews and complete BOQ preparation.

11. Relevant Standards and Technical Documents

Cable tray procurement may involve international technical standards.

IEC 61537:2023 covers cable tray and cable ladder systems, including mechanical requirements and testing methods.

NEMA VE 1 may also apply to specified metal cable tray systems.

However, cable trunking is outside the scope of IEC 61537.

Important Technical Documents

  • Product technical datasheets.

  • Manufacturing drawings.

  • Material specifications.

  • Safe working load information.

  • Protective coating specifications.

  • Applicable test reports.

  • Installation instructions.

  • Accessory drawings.

The required documents should be identified before material approval.

12. Evaluating Cable Tray Suppliers in Saudi Arabia

Supplier evaluation should begin with technical compatibility.

A lower quotation may not include the same material thickness, coating, fittings, or support components as another proposal.

Supplier Evaluation Checklist

  • Availability of the specified tray type.

  • Required dimensions and thickness.

  • Material and coating options.
