As essential components of electrical infrastructure in modern buildings, cable trays play a critical role in organizing and supporting cables. However, they also pose potential fire hazards if not properly managed. Combustible cable jackets, accumulated dust, and material flammability can turn cable trays into pathways for fire spread.

Shanghai Qiongkai Industrial Co., Ltd. has launched a new reinforced perforated cable tray designed to resolve a longstanding tradeoff in cable management: maintaining the ventilation benefits of perforations while preserving structural integrity.

As data centers evolve to support higher densities and more complex architectures, the critical infrastructure that supports them must keep pace. Among these essential components, cable trays and Unistrut channels (C-type steel) form the backbone of a data center's physical layer. A new comprehensive guide highlights the key considerations for selecting these components, focusing on mainstream types, performance requirements, and emerging industry trends.

Shanghai Qiongkai Industrial Co., Ltd., a specialized manufacturer of cable support systems and installation tools, has announced the successful completion of a shipment of high-performance wire rodders to a key client in Armenia in June 2025. This delivery complements the company’s existing supply of cable trays and seismic supports to the region, further strengthening its role in supporting local infrastructure development.

Shanghai Qiongkai Industrial Co., Ltd., a leading manufacturer specializing in the production of cable support systems including cable trays, ladders, and related accessories, today announced the successful completion of a major strategic initiative. The company has consolidated its corporate headquarters and manufacturing operations into a new, integrated facility located at No. 86 Dujiabang Road, Songjiang District, Shanghai.

Conventional cable ladders are often assembled by welding the rungs between two separate side rails. This method creates inherent vulnerabilities at the weld points, which can become sites for corrosion, micro-fractures, and structural failure over time. The One-Piece Galvanized Cable Ladder addresses this fundamental flaw.

Molded Galvanized Perforated Cable Trays are manufactured through a precision molding process, where high-quality steel sheets are shaped to create uniform perforations and a robust frame structure, followed by a galvanization treatment. This dual manufacturing approach is the cornerstone of their performance advantages. The molding process ensures consistent hole patterns—typically round, square, or slotted—that facilitate optimal ventilation, preventing heat buildup in bundled cables. Excessive heat is a major cause of cable insulation degradation and signal interference, making ventilation a critical factor for maintaining the longevity and reliability of electrical systems, especially in high-load industrial settings.

In an era where industrial sustainability is growing increasingly crucial, Shanghai Qiongkai Industrial Co., Ltd. is taking the lead through product system transformation, striving to address the significant environmental impact caused by traditional steel production. While steel manufacturing serves as the core pillar of modern infrastructure development, it also imposes a heavy ecological burden, and the company is committed to alleviating this issue through innovative initiatives.

A cable tray elbow is a critical component in cable management systems. It enables cable trays to make directional changes (horizontal or vertical bends) while maintaining a continuous path for cables. Acting as a “bridge” in cable routing, it ensures cables can navigate corners, elevations, or depressions smoothly, without compromising the integrity or organization of the cable network.

SHANGHAI, [October 2025] – Shanghai Qiongkai Industry Co., Ltd. has successfully completed a project to supply custom-perforated hot-dip galvanized steel cable trays to a major client in Italy. This collaboration highlights Qiongkai's expertise in delivering tailored solutions that meet specific technical and performance requirements for sophisticated European industrial markets.
