Protecting method for coating surfaces of steel components

The invention relates to a protecting method for coating surfaces of steel components. The protecting method comprises the following steps of 1, after construction of painting of the components is completed, the parts, needing paint protection, of the whole bodies of the components are subjected to first-layer wrapping by using hollow material and then fixed before hoisting; 2, then second-layerwrapping is carried out at the outer sides of a first layers on the parts, needing paint protection, of the components by using thick cotton cloth or rubber leather; 3, before the components are transported, an iron frame or a jig frame is made, the one or more components are assembled and fixed by using a steel bar bolt, and then the components are bound and fixed by using a binding tape or a steel wrapping tape; and 4, before the packed components are transported, the components are fastened by using a fixing rope and fixed on a transport vehicle or a shipping container, so that the components are stable on the trans
