Hollow sections

The shape, excellent strength properties and good weldability of structural hollow sections provide durable and light steel structures without limiting the freedom of design.

The excellent galvanising properties of structural hollow sections allow them to also serve in corrosive atmospheres.

Our special expertise includes materials for demanding applications in the boom and frame structures of lifting and transportation equipment.

Ruukki also manufactures special shapes and grades offering you a wide range of steels with beneficial zinc coating, forming, weather resistance and hardening properties.
