EN 10219 Steel Pipe

EN 10219 Steel Pipe
At UNIACERO, we proudly offer the European Standard EN 10219, a hallmark of quality and precision in the steel industry. This standard, often referred to as Euronorm, is ratified by European Standards Organizations, ensuring its credibility and reliability. EN 10219 is meticulously designed by experts through a transparent and consensual process, making it a model specification in the Single European Market. By choosing our EN 10219 steel pipes, clients are assured of a product that meets the highest European standards, facilitating easier access to European markets.
EN 10219 Specification
Our EN 10219 steel pipes are cold-formed welded structural hollow sections, crafted from non-alloy and fine-grain steels. These pipes undergo electric resistance welding (ERW) or submerged arc welding (SAW) to ensure durability and strength. They are delivered cold-formed, eliminating the need for subsequent heat treatment. This ensures the preservation of the steel’s inherent qualities. With UNIACERO, clients receive products that not only meet but exceed the EN 10219 specifications.
