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.
Galvanizing protects in two ways: 1  It forms a coating of corrosion-resistant zinc which prevents corrosive substances from reaching the more delicate part of the metal. 2  The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
