Rheinzink®

OCM is an official distributor of Rheinzink in the western US. We have inventory from 0.7mm(24ga) - 1.5mm(16ga) in Pre-Weathered Blue/Gray and Graphite Gray. We also carry these items with a pro-backer, which is a moisture protective barrier coating.

What is RHEINZINK®?

RHEINZINK® is the trade name for a titanium zinc alloy, manufactured in the form of thin gauge sheet metal, used for roofing, facade cladding, and roof drainage. RHEINZINK® is 99.995% pure electrolytic special high-grade zinc alloyed with small quantities of titanium and copper. These additional alloying elements are necessary for modifying the mechanical and technological properties of zinc in a way that the material can be used for exterior architectural projects.

RHEINZINK® is a monolithic alloy, not a coating on top of some other base metal. RHEINZINK® is environmentally friendly and fully recyclable, and with proper design and installation, the lifespan of RHEINZINK® as a roofing material ranges between 100 and 120 years while a wall application ranges between 200 and 300 years. The self-healing zinc carbonate that RHEINZINK® forms through exposure to air and water offers great resistance to corrosion and wear.

 

RHEINZINK® is available in three natural colors, Preweathered Blue Gray; Bright and Rolled; and Preweathered Graphite Gray.
