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 Pre Galvanized Cable Trunking Manufacturer Factory Direct Custom GI Metal Electrical Wire Cable Duct Trunking Supplier

Product Overview

Cable trunkings are the non-perforated cable trays, which have better sealing performance. After covering the trunking’s cover, the interior of the cable trunking will become a isolated space. It can will protect the cables been away from rainwater, stray animals and etc. Comparing with perforated cable trays, cable trunkings are better choices for outdoor installation.

Usually there are some limited slotts on the side plates of our cable tray for connections. Our company is equipped with laser cutting machines and can provide various perforated cable trays. If you have unique requirements for the shape and arrangement of the perforations, we support customization and provide them base on a cable trunking.

Key Features

Strong Corrosion Resistance

It can form a dense oxide film and has self - repairing ability, resistant to corrosion from moisture, acids, alkalis and salts.

Good Wear Resistance

The zinc layer has hardness and toughness, capable of withstanding friction and collision, reducing wear.

Good Aesthetic Property

It presents a uniform and bright silver - white appearance with high gloss, and is not prone to fading or color - changing.

Excellent Processing Performance

It has good plasticity and workability. The galvanized layer is not likely to peel off or crack during processing.

Good Economy

The process is simple and low - cost. With a long service life, it can reduce the overall cost.

Relatively Good Environmental Friendliness

There is less pollutant generated during production, and no harmful substances are released during use, meeting environmental requirements.

Common Parameters

Zinc layer thickness: The anti - corrosion grade of galvanized cable trays depends on the thickness of the zinc layer. Our company can provide cable trays with zinc layer thicknesses of 10μm, 20μm, 30μm, 40μm, 45μm, 50μm, 60μm, 65μm, and even thicker ones. If the thickness exceeds 65μm, customization is required.

Width: Common widths include 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm, 800mm, etc.

Height: General heights are 50mm, 60mm, 100mm, 150mm, etc.

Thickness: The thickness of the trough body and cover plate varies according to the specifications and load - bearing requirements of the cable tray. Taking steel galvanized cable trays as an example, when the width of the cable tray B < 300mm, the thickness of the trough body is generally not less than 1.2mm, and the thickness of the cover plate is not less than 1.0mm. When 300mm ≤ B < 500mm, the thickness of the trough body is not less than 1.5mm, and the thickness of the cover plate is not less than 1.2mm, etc.

Length: The standard lengths are usually 2m, 3m, 4m, 6m, etc., and can also be customized according to actual needs.

Application Scenarios

It is widely used in industries such as construction, power, communication, petrochemical, and metallurgy for the laying of indoor and outdoor cables. Specific application sites include electrical shafts, corridors, basements in buildings, as well as workshops, substations, and distribution stations in factories.

Frequently Asked Questions (FAQ)

What is the main advantage of cable trunking over perforated trays?

Cable trunkings are non-perforated and come with covers that form an isolated, sealed space. This provides superior protection against rainwater, dust, and stray animals, making them ideal for outdoor and sensitive environments.

Can the perforation patterns and dimensions be customized?

Yes. Equipped with high-precision laser cutting machines, we can customize unique hole shapes, perforation arrangements, width, height, and body thickness based on your project requirements.

What surface treatment options are available?

We offer Pre-galvanized, Hot-dip-galvanized (HDG), and Powder Coated finishes. Zinc coating thicknesses can range from 10μm to over 65μm depending on the required corrosion resistance.

What is the Minimum Order Quantity (MOQ) and sample policy?

The standard MOQ is 50 meters/pieces. We also provide free samples for quality inspection before proceeding with bulk orders.

Do you support OEM and ODM services?

Yes, we offer both OEM and ODM manufacturing services to meet custom branding, dimensional, and installation requirements under ISO and CE certified standards.
