Price of piping with openings at the bottom of cable trays

Cable trays with openings at the bottom typically cost between $20 and $100 per meter, depending on material, size, and design.Cable trays with perforated or slotted bottoms are often used to allow ventilation, drainage, and easier cable management. The price depends on several factors: Material: Stainless steel, galvanized steel, aluminum, and fiberglass (FRP/GRP) are common. Stainless steel and aluminum are more expensive due to durability and corrosion resistance, while fiberglass is lighter and often mid-range in cost . Tray Type and Design: Ladder trays are generally more economical than solid bottom trays because they use less material and allow easier cable access. Solid bottom trays with openings or perforations are slightly more expensive than standard ladder trays due to additional fabrication . Size and Dimensions: Wider and deeper trays that accommodate more cables cost more. Standard lengths are usually around 2.4 meters, and prices scale with width and depth . Installation Complexity: Labor and accessories (brackets, connectors, supports) add to the total cost. Open-bottom trays may reduce labor time compared to conduit piping because cables can be laid directly without pulling through enclosed pipes, saving up to 40–60% of installation costs . Estimated Price Range:Fiberglass or aluminum perforated trays: $20–$50 per meterGalvanized steel perforated trays: $30–$70 per meterStainless steel perforated trays: $50–$100 per meter Additional Considerations: Accessories like bends, tees, and supports are priced per piece and can add 10–20% to the total project cost. For large-scale installations, using open or perforated trays is generally more cost-effective than conduit piping due to reduced labor and material requirements . In summary, the exact price depends on material, tray dimensions, and installation requirements, but perforated or open-bottom cable trays are typically more affordable and easier to install than traditional conduit piping, making them a practical choice for commercial and industrial projects.
