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 Perforated Cable Tray Manufacturer Factory Direct Custom Steel Cable Tray Bulk Supplier

Product Overview

The characteristic of perforated cable trays is their excellent heat dissipation performance, which can meet the installation environments with high heat dissipation requirements. Ventilation and load capacity are both important aspects to be concerned will selecting cable trays. Comparing with cable trunkings, the perforated cable trays are more suitable for indoor installation.

Usually we follow the pill shape slotting pattern on all sides of our cable trays. 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.

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.
