German Hardware GU
We install premium quality UNI-JET hardware made by German manufacturer GU (Gretsch-Unitas).
Gretsch-Unitas has more than 100 years of experience in designing and manufacturing high quality furnishing. The first window hardware produced by our company appeared in 1907!!
Patented Ferguard Silber coating improves the anticorrosive properties of hardware by up to 10 times compared to standard metal. GU window hardware is capable to withstand 500 hours of immersion in brine without showing signs of rust – this is a convincing indicator of high quality. The average service life of Ferguard Silber coated hardware is 20 years.
All GU hardware come with mushroom studs, allowing you to increase the security of your windows easily and at no cost by installing anti-theft locking straps.
