Tailor-made solutions

OUR PROFILES ARE MUCH MORE THAN SPECIAL

Sipa Spa is specialized in the production of special cold-drawn profiles that are custom designed. It complies thoroughly with all supply requests and specifications, in terms of size, mechanical performance and surface quality.

Steel is by nature an environmentally friendly, recyclable and highly resistant material with excellent mechanical properties. It is processed using cold forming technology which strongly reduces waste and material surplus.
