UL Listed Flexible Metal Conduit for Building & Data Center Wiring

In a large-scale commercial building and data center wiring project, the client selected our PRWG Series UL1 Listed Flexible Metal Conduit to ensure safe protection for lighting circuits, office OA systems, and power distribution. The project demanded extremely high reliability and safety for the wiring infrastructure, as any failure could cause significant operational risks in both commercial offices and data centers. Therefore, the client focused on products that offered UL1 certification, fire resistance, flexibility, and long-term stability.

1. The PRWG series features a galvanized steel thin-wall construction, combining lightweight design with high strength to provide excellent mechanical protection during installation and operation. Its pull strength and impact resistance fully comply with ANSI/UL 1 and CSA 22.2 No.56 standards, ensuring that wires remain intact even under mechanical stress or impact. The conduit’s high flexibility allows for easy bending and routing during installation, even in complex pathways. This combination of flexibility and strength makes the PRWG series highly reliable across various building wiring and equipment installation scenarios.

   
   

2. To adapt to different environmental conditions, the PRWG conduit has an operating temperature range from -50℃ to +350℃ and an IP40 protection rating, capable of withstanding typical indoor temperature fluctuations and dust exposure, ensuring long-term performance of the wiring. This protective performance is particularly valuable for wiring in commercial building ceilings, server racks, and data centers, significantly reducing the risk of cable failures and maintenance needs.

3. For this project, the client specifically chose the Extra Reduced Wall type for office OA systems and overhead wiring. The ultra-thin wall design not only reduces material thickness and weight but also enhances flexibility in tight and complex spaces, significantly improving installation efficiency. Additionally, for space-constrained applications such as light fixtures, elevators, and control panels, the small-diameter PXRWG series (5/16" and 9/16") offers a smaller bending radius, allowing smooth routing through tight corners and intersecting conduits. Installation teams reported that these small-diameter conduits were far easier to work with compared to traditional rigid conduits, especially in high-density wiring environments.

   
   

4. Beyond mechanical performance and ease of installation, the PRWG series strictly adheres to RoHS environmental standards, ensuring environmentally friendly materials free of harmful substances. While meeting UL certification and low fire hazard requirements, the product also supports sustainable development and green building initiatives. This is particularly important for modern commercial buildings and data centers, where environmental compliance and certification requirements are increasingly stringent, especially in North America.

By adopting the PRWG and PXRWG series conduits in this project, the client successfully achieved faster installation, enhanced wiring safety, and long-term system reliability. The combination of flexibility and strength in high-density wiring scenarios allowed installation teams to complete tasks quickly while minimizing potential maintenance risks. Furthermore, the comprehensive UL and CSA certifications provided full confidence in regulatory compliance, ensuring smooth project execution.

Overall, the PRWG series flexible metal conduits not only meet stringent UL certification requirements but also excel in flexibility, durability, installation convenience, and environmental compliance. Whether for large commercial buildings, modern office spaces, or high-demand data centers, the PRWG series delivers high-performance, low-risk, and sustainable wiring solutions. This case further validates the product’s reliability in complex environments and provides a mature, efficient, and compliant solution for future projects of similar scale.
