Calcium steel plate is one of the metal calcium series, by the high density calcium silicate board surface by chemical method, or inorganic enamel will be high weatherability fluorocarbon aluminium zinc steel plate and their organic combination, supplemented by high temperature and pressure, static pressure curing process, and at the back with a layer of a closed, moisture, strengthening the role of aluminium coated fabric. Steel calcium plate unique structure, obtained a number of national patents, is a kind of environmental protection, energy saving new material.
