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.

Bulk Pre Galvanized Cable Trunking Manufacturer Wholesale GI Electrical Metal Trunking Factory Direct Supplier

Product Overview

Cable trunkings are non-perforated cable trays, engineered with enhanced sealing performance. Once secured with the trunking cover, the interior forms a completely isolated environment, effectively safeguarding cables from exposure to rainwater, stray animals, and surrounding contaminants. Compared to conventional perforated cable trays, cable trunkings provide exceptional protection, making them ideal for outdoor installation systems.

Standard configurations feature limited slots along the side plates to facilitate secure system connections. Utilizing high-precision laser cutting machinery, a comprehensive range of perforated cable trays can be manufactured to exact parameters. Custom perforated configurations regarding shape, spacing, and overall layout are fully supported directly on standard cable trunking designs.

Key Features

Strong Corrosion Resistance

Forms a dense oxide protective barrier with self-repairing capabilities, providing resilience against moisture, acids, alkalis, and salts.

Exceptional Wear Resistance

The specialized zinc layer exhibits superior hardness and toughness to withstand abrasion, mechanical friction, and heavy impact.

High Aesthetic Value

Delivers a bright, uniform silver-white finish with premium gloss levels that remain stable against fading or discoloration over time.

Reliable Workability

Exhibits excellent plasticity during fabrication, ensuring the galvanized layer prevents peeling, chipping, or micro-cracking during installation.

Cost-Effective Lifecycle

Features streamlined production efficiency and prolonged structural life, significantly lowering long-term maintenance and replacement costs.

Eco-Friendly Design

Engineered via low-emission processes with non-hazardous material finishes, adhering to strict sustainable building and safety regulations.

Standard Specifications & Sizing

Zinc Layer Thickness: The corrosion protection level depends directly on the zinc layer thickness. Standard selections include 10μm, 20μm, 30μm, 40μm, 45μm, 50μm, 60μm, and 65μm. Custom coatings beyond 65μm are available upon request.

Standard Widths: Available in 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm, and 800mm profiles.

Standard Heights: Available in 50mm, 60mm, 100mm, and 150mm system heights.

Thickness Configuration: Body and cover thickness adapt to physical specifications and load profiles. For galvanized steel systems with width B < 300mm, body thickness is typically ≥ 1.2mm with a cover thickness ≥ 1.0mm. For 300mm ≤ B < 500mm, body thickness is ≥ 1.5mm with a cover thickness ≥ 1.2mm.

Standard Lengths: Regular production lengths include 2m, 3m, 4m, and 6m, with custom sizing tailored to specific spatial layouts.

Application Scenarios

These cable management systems are utilized across modern building infrastructure, electrical power plants, telecommunication networks, petrochemical complexes, and metallurgical installations for structured indoor and outdoor cabling runs. Primary installation areas include:

Commercial & residential electrical shafts, risers, and utility corridors.

Underground basements, structured parking facilities, and transit centers.

Industrial manufacturing workshops, heavy substations, and power distribution hubs.

Frequently Asked Questions

What makes cable trunking better suited for outdoor installations than perforated cable trays?

Cable trunking features an unperforated structure fitted with a secure top cover. This configuration isolates internal wiring, shielding cabling from rainwater, harsh debris, and animals, whereas perforated designs leave cables more exposed to outdoor elements.

Can perforated patterns be customized on standard trunking profiles?

Yes. In-house high-precision laser cutting machinery enables customization of perforation patterns, hole dimensions, and spacing arrangements according to distinct structural or ventilation requirements.

What zinc layer thickness is recommended for corrosive environments?

Standard protective zinc thicknesses range from 10μm to 65μm. For highly corrosive, humid, or exterior chemical settings, a heavy-duty coating exceeding 65μm can be customized to maximize lifespan.

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

The minimum order volume is 50 meters (or pieces). Production capacity spans 10,000 to 40,000 meters depending on specified thicknesses, material selections, and customization complexity.

Are product samples available prior to full-scale ordering?

Yes, free product samples are provided to verify physical build quality, dimensional tolerance, and surface finishes before bulk dispatch.
