Natina Steel Solution reacted with the minerals in the galvanized steel and enhanced the appearance of the shiny galvanized guardrails. Natina's rich, earthy brown finish blends in fantastically on this project in St. George, Utah. Natina requires little to no maintenance and lasts longer than the other alternatives like power coating, paints or weathering steel (A588). All our solutions are natural, environmentally safe and non-toxic.
