Signs and Symptoms of Psoriasis. Psoriasis is a common autoimmune skin disorder which occurs when the skin cells replicate too quickly. The skin produces new cells at many times the normal rate, creating inflamed, scaly and red patches of skin, called plaques, where the old skin has not shed quickly enough.
Galvanization is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.
Galvannealed or galvanneal is the result from the processes of galvanizing followed by annealing of sheet steel. Galvannealed steel is a matte uniform grey color, which can be easily painted. In comparison to galvanized steel the coating is harder, and more brittle.
