S355K2H structural hollow profiles are products under the EN 10210-1 standard and are part of the hot-rolled structural steel tubes of non-alloy and fine-grained steel. With good toughness and weldability, it is particularly suitable for structural applications that require high strength and good toughness. This material is mainly used in engineering fields such as construction and offshore platforms.
EN 10210-1 S355K2H structural hollow tubes have various specifications, including round, square, rectangular and oval, and can be customized in different sizes and shapes according to specific application requirements. In addition, it can also produce steel tubes with different wall thicknesses as needed to meet different load-bearing requirements.
