EN 39 Scaffolding Pipe
At UNIACERO, we proudly offer steel pipes that adhere to the European norm EN 39, a standard that specifies the requirements for unalloyed carbon steel welded round tubes. These tubes are primarily intended for use in the construction of scaffolding, ensuring robustness and safety in construction projects. Originating from Europe, the EN 39 standard has been recognized and adopted globally, reflecting its high quality and reliability. Our steel pipes are not only compliant with this standard but also resonate with the dedication and expertise that UNIACERO brings to the international trading arena.
EN 39 Specification
Our EN 39 steel pipes are meticulously crafted, ensuring they meet the stringent requirements of the standard. These tubes are designed for use with EN 74 couplers in the construction of falsework and working scaffolds. They come with a specified outside diameter of 48,3 mm and thickness options of 3,2 mm or 4,0 mm. The protective coating on our pipes is in line with European and International Standards, ensuring longevity and resistance to environmental factors. Moreover, our pipes undergo rigorous inspection and testing to guarantee their quality and durability.
