NPS® PTC® Column

Ideal as a design component thanks to its numerous colour finishes, polishing or chrome plating. It is recommended exploit available space to the fullest, thanks the compactness of its sections given the same required performance.

With UNI EN 13225 CE marking, the patented NPS® PTC® Column is realised using spun concrete for high performance, up to class C70/85.

The spinning treatment allows a reduction in the structural section, with resulting benefits in terms of usability of space, a greater bearing capacity compared to traditional structures and extremely homogenous surfaces.
