Two main problems of precoated steel sheet for selecting application in the field of architecture,  corro-sion resistance and durability of precoated steel sheet, are presented in this paper. Basing on the coating characteristic principle, the coating structured characteristic, corrosion resistance of substrate,  weathering properties of coatings and durability classification of precoated steel sheet are discussed.
Keywords: precoated steel sheet; coating structured characteristic; corrosion resistance; weathering property; durability
