Structural tubes

Tuflesa manufactures hollow-section welded structural tubes for construction, cold formed from non-alloy and fine grain steel, according to the EN 10219 standard part 1 and 2, in S235JR, S275J0H and S355J2H grades and special highly-resistant steels.

For their application in the different solutions of the customer, these materials require great resistance and reliability of the tubular structures. With regard to the technical specifications, they may be round, square and rectangular. In turn, the surface finishes must be highly resistant to corrosion.

We are the most flexible tube factory on the market thanks to the total efficiency of our manufacturing process, logistics and the commitment of our employees.
