THE BEST GRADE AND FINISH FOR YOUR PROJECT

Our broad range of austenitic stainless steels offers outstanding solutions for exterior building cladding, where strength and corrosion resistance are critical. Our ferritic grades make it easy to benefit from the advantages of stainless steel also in interior building applications. Furthermore, our wide offer of finishes and decorative options provides designers and architects with incomparable freedom and appealing results.

OUR OFFER FOR INNOVATIVE FACADES AND PANELS

Stainless steel panels and claddings are increasingly sought-after solutions to add an innovative touch that makes architectural projects stand out. Our range has thus developed to enhance your exterior project’s design and creativity with new special surface finishes – Vernest®, patterned or decorated – while building interiors and elevator claddings can increase their appeal with our antifingerprint finish Silver Ice® and Silver Ice® colored.

3 Indice di PREN Corrosion resistance index
The ability of stainless steel grades to resist pitting corrosion is expressed by a numeric indicator called PREN (Pitting Resistance Equivalent Number).
PREN can be calculated using a mathematical formula, which uses mass-percentage of selected chemical elements found in stainless steel grades as input variables.
PREN(Austenitic)=%Cr+3.3(%Mo)+16(%N) – PREN(Ferritic)=%Cr+3.3(%Mo)
4 The availability of the 0.35 mm thickness will be checked on request.
