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 Powder Coated Cable Trunking Factory Direct Heavy Duty Metal Cable Raceway Manufacturer Custom OEM Industrial Wiring Duct Supplier

Product Overview

Cable trunkings are non-perforated cable trays designed with superior sealing capabilities. Once covered with the trunking lid, the interior transforms into a completely isolated protective space, effectively safeguarding cables from rainwater, moisture, stray animals, and other environmental hazards. Compared to standard perforated designs, cable trunkings provide an optimal solution for rigorous outdoor routing.

Standard configurations feature limited connection slots on side plates. Equipped with advanced laser-cutting machinery, custom perforated layouts, specialized patterns, and bespoke side-wall hole designs are fully supported to match specialized engineering requirements based on standard trunking structures.

Key Features

Strong Corrosion Resistance Forms a dense oxide protective layer with self-repairing properties, resisting corrosion from moisture, acids, alkalis, and salts.

High Wear Resistance Hardened zinc coating withstands friction, transport wear, and direct surface impact throughout structural lifespans.

Aesthetic Appearance Provides a consistent, reflective silver-white finish with high gloss that prevents discoloration and fading over time.

Superior Processing Performance High plasticity ensures the zinc protective layers do not peel, flake, or crack during bending, punching, or cutting.

Cost Efficiency Streamlined manufacturing delivers an economical solution with long-term durability, minimizing maintenance and life-cycle costs.

Eco-Friendly Manufacturing Clean production techniques eliminate toxic release during fabrication and operational service, meeting strict environmental compliance.

Common Parameters

Zinc Layer Thickness Anti-corrosion grades depend directly on coating thickness. Available variations include 10μm, 20μm, 30μm, 40μm, 45μm, 50μm, 60μm, and 65μm. Custom coatings beyond 65μm are manufactured on request.

Width Specifications Standard sizes range from 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm, up to 800mm and higher.

Height Dimensions Engineered in uniform profile heights of 50mm, 60mm, 100mm, and 150mm.

Material Thickness Guidelines Wall and cover thickness adjust based on structural load ratings. For galvanized steel units under 300mm width, the body maintains ≥1.2mm and cover ≥1.0mm. For spans 300mm ≤ Width < 500mm, body thickness is ≥1.5mm and cover is ≥1.2mm.

Standard Lengths Standard runs are fabricated in lengths of 2m, 3m, 4m, and 6m, with full custom lengths cut per job site conditions.

Application Scenarios

Cable trunkings are essential across civil infrastructure, industrial plants, energy production, telecommunications, petrochemical facilities, and metallurgical processing. They guarantee safe, clean power and signal distribution within high-density environments like building shafts, service corridors, basements, production workshops, electrical substations, and centralized control hubs.

Frequently Asked Questions

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

The non-perforated design paired with a secure top cover creates a tightly sealed channel, shielding internal cables from rainwater infiltration, direct sunlight, corrosive elements, and small animals.

Can perforated slots be customized on the cable trunking?

Yes. Using industrial laser-cutting machinery, hole shapes, sizes, and layout patterns can be fully customized along trunking side rails or bases to match engineering needs.

What materials are available for your cable trunking systems?

We supply profiles manufactured in carbon steel, marine-grade stainless steel (SS304, SS316L), and lightweight aluminum alloys.

What surface finishes do you offer to prevent corrosion?

Depending on application environments, you can choose pre-galvanized, hot-dip galvanized (HDG), or electrostatic powder-coated finishes across various zinc layer thicknesses.

Do you support product samples and OEM orders?

Yes, free samples are available for validation, and we provide end-to-end OEM and ODM production capabilities supported by ISO and CE certifications.
