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.

Wholesale Non Perforated Powder Coated Cable Tray Manufacturer Solid Bottom Cable Trunking Direct Factory Supplier

Product Overview

Cable trunkings are non-perforated cable trays designed for superior sealing performance. Once the trunking cover is secured, the interior forms an isolated and protective environment, shielding cables from rainwater, stray animals, and harsh external elements. Compared with perforated trays, solid cable trunkings represent the optimal choice for demanding outdoor installations.

Typically, limited slots are incorporated on the side plates of our cable trays for connection purposes. Equipped with advanced laser cutting machinery, our company provides versatile perforated cable tray configurations. Unique requirements regarding hole shapes and layouts can be custom-manufactured based on our standard cable trunking design.

Key Features

Strong Corrosion Resistance

Forms a dense protective oxide film with self-repairing properties, offering excellent defense against moisture, acids, alkalis, and salts.

Good Wear Resistance

The robust zinc layer offers high hardness and toughness, built to withstand everyday friction and collision impacts.

Good Aesthetic Property

Presents an attractive, uniform, high-gloss silver-white finish that resists long-term fading and discoloration.

Excellent Processing Performance

Engineered with high plasticity and workability; the galvanized layer will not peel or crack under secondary processing.

Good Economy

Combines cost-effective manufacturing with an extended operational lifespan, driving down project lifecycle expenditures.

Relatively Good Environmental Friendliness

Manufactured with reduced pollutants and releases no harmful substances during practical use, meeting eco-standard compliance.

Common Parameters

Zinc Layer Thickness: The anti-corrosion grade of galvanized cable trays depends directly on zinc layer thickness. Standard offerings include thicknesses of 10μm, 20μm, 30μm, 40μm, 45μm, 50μm, 60μm, 65μm, and beyond. Tailored custom configurations are provided for requirements exceeding 65μm.

Width: Standard widths are available in 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm, 800mm, and other dimensional specs.

Height: General height options include 50mm, 60mm, 100mm, 150mm, and custom options.

Thickness: Trough body and cover plate thickness are determined by tray specifications and engineering load-bearing requirements. For galvanized steel cable trays: width (B) < 300mm requires body thickness ≥ 1.2mm, cover plate ≥ 1.0mm; width 300mm ≤ B < 500mm requires body thickness ≥ 1.5mm, cover plate ≥ 1.2mm.

Length: Available standard lengths include 2m, 3m, 4m, and 6m, customizable upon demand.

Application Scenarios

Cable trunkings are extensively deployed across construction, power distribution, telecommunications, petrochemical, and metallurgy sectors for routing both indoor and outdoor cabling. Typical installation environments include electrical shafts, service corridors, basements, production workshops, substations, and electrical distribution plants.

Frequently Asked Questions

Why choose cable trunking over perforated cable trays for outdoor projects?

Cable trunkings feature a non-perforated body and a fitted cover, producing an enclosed and sealed channel. This barrier effectively shields critical cabling from rainwater penetration, physical wear, debris accumulation, and wildlife damage.

Can the dimensions and perforation layout be fully customized?

Yes. Utilizing high-precision laser cutting equipment, perforation shapes, hole arrangements, side rail heights (25–600mm), and widths (50–1000mm) can be tailored to meet engineering blueprints.

What materials and surface finish options are supported?

We manufacture cable systems using Carbon Steel, Stainless Steel (304 / 316L), and Aluminum Alloy. Available protective finishes include Pre-galvanized, Hot-Dip Galvanized (HDG), and specialized Powder Coating.

What is the minimum order quantity (MOQ) and production capacity?

Our standard Minimum Order Quantity (MOQ) is 50 meters/pieces. With streamlined production lines, our monthly capacity ranges from 10,000 to 40,000 meters depending on the exact material and design.

Are product samples available prior to full-scale orders?

Yes, free product samples are offered upon request to allow technical evaluation of dimensions, materials, and surface quality before placing volume commitments.
