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.

Stainless through cable trays are also divided into perforated and non-perforated types. The non-perforated ones have better sealing performance and are suitable for outdoor installation, while the perforated ones are suitable for indoor installation. The characteristic of perforated cable trays is their excellent heat dissipation performance, which can meet the installation environments with high heat dissipation requirements. Our company is equipped with laser cutting machines and can provide various perforated cable trays. If you have requirements for the shape and arrangement of the perforations, we support customization.

In terms of materials, stainless-steel materials are divided into 316L, 304, and 201. Among them, 316L has the best anti-corrosion performance and is the most expensive, while 201 has the worst anti-corrosion performance but is the cheapest. Our company can provide stainless-steel cable trays with different standards.

Key Product Features

1. Excellent Corrosion Resistance

Stainless steel contains chromium and nickel, forming a dense and stable passivation film on the surface. This effectively shields the tray from moisture, acids, alkalis, and salts. Grades like 316L provide exceptional durability in coastal areas and chemical facilities.

2. High Strength & Durability

Highly strong and rigid structure allows the trays to bear significant loads without deformation or structural failure. Exceptional resistance to vibration and mechanical impact ensures secure and reliable cable management.

3. Good Heat Resistance

Maintains structural stability across broad temperature ranges. It easily withstands elevated operating temperatures generated by running power cables, preventing high-temperature warping and securing power system longevity.

4. Modern Aesthetic Property

A bright, smooth metallic finish integrates seamlessly into open-ceiling concepts. Highly resistant to rust and discoloration, making it an optimal choice for architectural, office, and commercial environments.

5. Good Fire Resistance

Constructed from completely non-combustible raw materials. In emergency scenarios, it impedes fire spread along cabling runs, helping mitigate secondary hazards and damage.

6. Easy Installation & Maintenance

Engineered for straightforward assembly, handling, and modifications. The sleek surface discourages particulate accumulation, reducing cleaning frequency, labor overhead, and ongoing maintenance costs.

7. Good Electrical Performance

Delivers dependable conductivity alongside built-in electromagnetic shielding. Isolates electromagnetic interference (EMI) to protect adjacent instrumentation and support signal clarity.

Frequently Asked Questions (FAQ)

Q What materials are used to manufacture the through cable tray?

The cable trays can be manufactured using steel, stainless steel (such as 316L), alloy, and FRP (Fiberglass Reinforced Plastic).

Q Are customized dimensions and OEM services available?

Yes. Both OEM and ODM are fully supported. Widths (50–1000mm), heights (25–600mm), lengths (1–10m), thickness (0.5–2.0mm), and perforable patterns can be customized.

Q What surface finishes and coating options are available?

We offer Raw, Galvanized, Hot-Dip Galvanized (HDG), and Powder Coated surface finishes with color options including Silver, Black, Green, and custom designs.

Q What are the standard order terms, MOQ, and lead times?

The minimum order quantity (MOQ) is 50 meters. Standard delivery takes approximately 25 days with price terms available in EXW, FOB, CIF, and CFR via Shanghai or Tianjin ports.

Q Can I request a product sample before placing a bulk order?

Yes, free samples are provided upon request, and online technical support is available for product assessment and post-purchase needs.

Q What makes stainless steel cable trays suitable for harsh environments?

Stainless steel naturally develops a passivation layer that resists acids, alkalis, salts, and moisture. Combined with superior fire resistance, mechanical load strength, and EMI shielding, it excels in chemical and coastal facilities.
