Durable & Safe Industrial Electrical Wiring Solution for KSA & Gulf
In today’s construction and industrial projects, electrical safety and durability are the main concerns. The uPVC Electrical Conduit – 40 mm (1¼″) – Class 4 Heavy Duty is designed to stand up to mechanical stress, corrosion, and the elements to the max.
It is a heavy-duty conduit that is very suitable for industrial, commercial, and high-stress residential applications in the KSA and the Gulf region, where the installations are affected by harsh climates, high temperatures, humidity, and even physical damage.
The unplasticized PVC (uPVC) that is used for making this conduit is of top quality, and it guarantees safety for a long time. The conduit not only protects your electrical wiring but also lowers your maintenance costs and installation difficulties.
The uPVC Electrical Conduit – 40 mm (1¼″) – Class 4 Heavy Duty is a premium, high-strength conduit designed to provide maximum protection and reliability for electrical wiring in industrial, commercial, and high-stress residential projects across the KSA and Gulf region. Manufactured from unplasticized polyvinyl chloride (uPVC), this conduit offers excellent insulation, corrosion resistance, and mechanical strength, ensuring that electrical systems remain safe, organized, and durable over time.
Unlike light or medium-duty conduits, the Class 4 Heavy Duty conduit is engineered for high-stress environments, where wiring may be exposed to mechanical shocks, physical impact, and environmental hazards. Its robust construction makes it the preferred choice for industrial installations, large commercial complexes, and critical residential wiring that demands long-term reliability.
