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 Split Cable Trunking with Partition Manufacturer Two Compartment Cable Duct Factory Direct B2B 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)

Q: Why choose cable trunkings over perforated cable trays?

A: Cable trunkings feature a non-perforated design with an enclosed cover that creates an isolated interior space. This provides superior sealing to protect wiring against outdoor elements like rainwater and interference from animals.

Q: What surface finish options are available for the cable trays?

A: Surface treatment options include Pre-galvanized, Hot-dip galvanized (HDG), and Powder Coated finishes, allowing optimal corrosion resistance tailored to specific indoor or outdoor environments.

Q: Can dimensions and perforation patterns be customized?

A: Yes, with in-house laser cutting machinery, customization is fully supported for custom widths, side rail heights, overall lengths, and tailored perforation shapes and patterns.

Q: What is the Minimum Order Quantity (MOQ) and production capacity?

A: The standard MOQ starts at 50 meters/pieces. Our manufacturing facilities maintain a capacity between 10,000 to 40,000 meters depending on the product specifications.

Q: Are product samples available before placing bulk orders?

A: Yes, free samples can be arranged upon request to allow quality evaluation of the materials and surface finishing.
