Price of making a box for cable trays

The cost of making boxes from cable trays depends on material type, size, fabrication method, and labor, typically ranging from $10 to $50 per small custom box using standard steel or aluminum trays.

Material Costs

Cable trays are available in galvanized steel, stainless steel, aluminum, and wire mesh, with prices per meter ranging from $2 to $25 depending on material, type, and finish . For small boxes, the required tray length is usually 1–2 meters, so raw material costs can range from $5 to $50 per box depending on the metal and thickness . Steel is the most cost-effective, while aluminum and stainless steel are pricier but lighter and corrosion-resistant .

Fabrication and Labor

Transforming a cable tray into a box involves cutting, bending, welding, and finishing. Labor costs vary by region and complexity:

• Cutting and bending: Simple hand tools or small machinery can be used for wire mesh or perforated trays, reducing labor costs .
• Welding and assembly: For steel or aluminum trays, welding adds to labor and energy costs. Skilled labor may charge $15–$50 per hour, with a small box taking 1–2 hours to fabricate .
• Finishing: Powder coating or galvanizing adds durability but increases cost by 10–20% .

Additional Cost Factors

• Tray type: Ladder trays are heavier and more expensive than wire mesh trays, which are easier to cut and assemble .
• Box size: Larger boxes require more material and labor.
• Bulk production: Producing multiple boxes at once reduces per-unit cost due to economies of scale .
• Shipping and handling: Heavier metals increase transport costs, especially for large-scale projects .

Estimated Price Range

For a small to medium-sized box made from standard steel or aluminum cable trays:

• Wire mesh tray box: $10–$20 per unit
• Galvanized steel tray box: $15–$35 per unit
• Aluminum tray box: $25–$50 per unit Custom sizes, thicker metals, or additional finishing can increase costs further. For large-scale production, bulk orders and modular designs can reduce costs by 20–40% .

Conclusion

The total cost of making boxes from cable trays is influenced by material choice, fabrication complexity, labor, and finishing. Using wire mesh or pre-cut modular trays is the most cost-effective approach, while aluminum or stainless steel provides durability at a higher price. Planning for bulk production and efficient cutting can significantly reduce per-unit costs.
