How can steel structures be divided into general steel structures, large steel structures and other steel structures?
There is no standard and strict definition of steel structure division.
For the general structure (such as general plant, Party A has no special requirements), tend to use more saving, anti rust effect is not very high iron red or red lead; but for the steel structure anticorrosive effect of higher requirements (such as bridge or country of some important buildings), have good anti rust effect of fluorocarbon paint, for example paint.
Specification for design of steel structure GB50017-2003 is not defined, only in 8.6.1 said a cross over 60m calculation of large span steel roof. In civil engineering, general light plant "steel structure", "medium factories steel structure, heavy plant" steel structure "and" other steel structure ";" according to the structure type of frame structure, frame structure, frame structure, frame structure, "" other structures".
