Seamless galvanized square hollow section 180x180x12 is a heavy structural steel profile without weld seams, protected against oxidation by a layer of zinc. It is manufactured by hot deformation of solid cylindrical steel billets. The outer dimension of the product is 180x180 mm, and the wall thickness is 12.0 mm. Delivered in lengths of 4 to 12.5 m. The weight of one linear meter is 61.36 kg, meaning one metric ton contains 15.8 m.

This size is manufactured according to the DSTU 8940 ( ≈ EN 10210-2 ) standard, which in its technical requirements serves as a functional analogue to the European standard EN 10210-2 (for hot-finished structural hollow sections). The base material is structural steel grade 20 ( S235JRH ).

The absence of a weld seam guarantees absolute strength and resistance to high bending and torsional loads. According to the standards, the rolled product is designed for heavy structural components. The profile is used for constructing frames of large industrial warehouses, bridge foundations, structural piling systems, underground mine support arches, and high-strength load-bearing pillars.
