UGIGRIP® 4311 introduction

In addition to their excellent corrosion resistance which ensures a long service life for structures over several decades, the UGIGRIP® range provides a guarantee of:

Higher mechanical properties than with conventional steel, which allows the use of smaller cross sections or a reduction in reinforcement (meaning weight and labour savings);

Mechanical properties – yield strength and elongation – meeting the requirements of Eurocode 8, class M for earthquake-resistant construction;

A selection of non-magnetic stainless steels for buildings where this property is required: hospitals, banks, airports, meteorological stations, etc.

Mechanical properties at high temperature – tensile and creep – exceeding those of conventional steels, giving improved fire resistance;

A very low thermal conductivity which gives this product exceptional properties for treating thermal bridges.

New ECISS harmonized European standard currently being prepared.
In accordance with European design codes in the construction field, the products of the UGIGRIP® range comply with Eurocode 2 (cf. prEN 1992-1-1 sub-section and Eurocode 3 (cf. prEN 1993-1-4).
