New steel microwave tower put forward in this thesis is a tower structure which cross section is triangle and the legs are cold-formed 60° single angles, the rest members all are cold-formed single angles.

The varied types of horizontal plane, vertical plane and branch member of the steel microwave tower are compared to find their influences on the standardized design and cost.

It introduces the lectotype of the steel structural microwave communication tower from three aspects of plane lectotype,elevation lectotype and web-member lectotype,represents the economical influences of the lectotype,and discusses the economical influences of foundation design and selection to the steel structural microwave communication tower,which will supply reference to designers.

The corrosion resistance of JT245 tower structural steel was tested through interior accelerated corrosion test, electrochemical corrosion test, outside atmospheric corrosion test and surface rusty scale analysis.
