What cable management products does Qiongkai manufacture?

Qiongkai manufactures wire mesh (basket) cable trays, perforated and solid-bottom cable trays, ladder trays, heavy-duty series trays, cable trunking, conduit, tray accessories, strut channel in 41x21, 41x41, 41x62 and 41x82 profiles, seismic brackets and light-gauge metal stud framing.

Which finish should I choose: pre-galvanized, hot-dip galvanized, stainless steel or FRP?

Pre-galvanized and electro-galvanized steel suit dry indoor areas. Hot-dip galvanized steel is the common choice for outdoor and industrial plants. Stainless steel 304 suits food and clean environments, while 316/316L and FRP are preferred for coastal, offshore and chemical exposure. Our engineers can review your site conditions before you finalize the specification.

Can Qiongkai produce custom sizes and non-standard profiles?

Yes. With 12 assembly lines and about 60 heavy-duty machines across 3 factories, we produce custom widths, side heights, thicknesses, hole patterns and profiled sections, including a custom profiled section solution for an offshore LNG project in Qatar.

Which projects and markets has Qiongkai supplied?

References include corrosion-resistant CT series cable trunking for Shanghai Hongqiao International Airport, FRP cable trays for extreme conditions in Qatar and Thailand, FRP-lined steel trays for an outdoor project in Thailand, a heavy-duty tray solution for a large pig farm in Paraguay and HDG cable tray shipments to Italy.

Product Description

Product Overview

Cable trunkings are non-perforated cable trays featuring superior sealing performance. Once covered with the trunking lid, the interior forms an isolated, highly secure environment that actively protects enclosed cables from rainwater, moisture, stray animals, and foreign intrusions. Compared to standard perforated cable trays, solid-bottom cable trunkings serve as a far more dependable solution for outdoor cable management and demanding environments.

Under standard production, limited connection slots are engineered onto the side plates for streamlined installation. With laser cutting technology in-house, we manufacture a comprehensive selection of cable routing solutions. Bespoke designs, distinct cutout shapes, and customized slot layouts based on specific project requirements are fully supported.

Key Features

Strong Corrosion Resistance Forms a self-repairing dense oxide passive layer offering robust defense against moisture, chemical vapors, acids, alkalis, and industrial salts.

Wear & Impact Resistance Toughened zinc metallurgical bonding withstands rigorous physical transit, pulling friction, and site-level collision without structural damage.

Clean Aesthetic Quality Provides a uniform, high-gloss silver-white surface finish designed to prevent fading, discoloration, and weathering over prolonged deployments.

Mechanical Ductility Offers high mechanical plasticity and precision workability; the protective surface layer does not peel, chip, or flake during secondary field cutting.

Economic Efficiency A dependable, low-maintenance protective solution that simplifies infrastructure operations and reduces whole-life maintenance expenditure.

Environmental Safety Manufactured through controlled low-emission engineering methods, creating a non-toxic channel that produces no off-gassing during operation.

Galvanized steel cable trunking structure

Common Parameters & Specifications

Zinc Layer Thickness: The ultimate anti-corrosion rating of galvanized cable trays depends on the thickness of the applied protective zinc layer. Standard offerings include zinc layer thicknesses of 10μm, 20μm, 30μm, 40μm, 45μm, 50μm, 60μm, and 65μm. Enhanced protective coatings exceeding 65μm are engineered on demand via heavy-duty hot-dip galvanization.

Standard Dimensions: Common tray widths range across 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm, and 800mm. Standard side rail heights include 50mm, 60mm, 100mm, and 150mm. Standard tray section lengths are supplied at 2m, 3m, 4m, and 6m, with tailored section profiles cut to custom site dimensions.

Material Thickness: The thickness of the trough body and its top cover plate corresponds directly to load ratings and span criteria. For galvanized steel systems with a width (W) < 300mm, minimum structural thickness requires ≥1.2mm for the trough body and ≥1.0mm for the cover plate. For 300mm ≤ W < 500mm, the body requires ≥1.5mm and the cover requires ≥1.2mm.

Frequently Asked Questions

What is the difference between cable trunking and perforated cable trays?

Cable trunking features an unperforated bottom and a fitted cover plate, creating an enclosed environment that shields wires against water, debris, and environmental wear. Perforated trays feature slotted bases to optimize heat dissipation, making them suited for indoor power distribution where ventilation is a priority.

Can cable trunking profiles be tailored to project specifications?

Yes. We support custom production runs covering specific widths (50–1000mm), side heights (25–600mm), gauge thicknesses, material grades, and connection slot geometries using CNC laser cutting machinery.

Which surface treatment is recommended for external installation?

Hot-dip galvanized (HDG) finishes with thicker zinc coatings (50μm to over 65μm) or stainless steel (304/316L) are recommended for external, seaside, or chemically aggressive environments due to their protective properties.

Are free evaluation samples available prior to full production runs?

Yes, free product samples are provided to help assess structural gauge, fit, finish, and engineering performance before placing bulk commercial orders.

What international export price terms and payment methods are supported?

We accommodate standard international trade conditions, offering EXW terms for less-than-container loads (LCL), as well as FOB, CIF, CFR, DDP, and DDU terms for full container shipments (FCL) managed via Shanghai or Tianjin ports.
