GRK Fasteners revolutionary Climatek™ coating is available only on GRK products.
GRK's Climatek™ coating consists of a total of six layers of various materials, including three layers of zinc-polymer.
Climatek™ has been tested for salt spray resistance, and more importantly, for Kesternich durability. Kesternich cycles are a more advanced way of testing a coated material. Each Kesternich cycle simulates heat, cold, wind, water, salt as well as a variety of other elements, whereas salt spray merely uses salt water for its tests.
Climatek™ passed 29 Kesternich cycles, making it the most advanced coating of its kind.
