In the application of steel tower

Theoretical weight 1, tower steel
Unit length of theoretical weight certain specifications of steel per unit length or area of the steel weight called the specification of the steel. Angle steel, channel steel, steel, flat steel usually takes the theory of weight every 1 metres in length as the reference of theoretical weight, steel plate by theoretical weight per square meter of area as the reference of theoretical weight. Theoretical weight real according to the actual length of X per unit length of theoretical weight or the actual area of X unit area weight calculation theory.
2, the actual weight of steel tower
Refers to the actual weight weighing steel, known as the actual weight.
Contact between the 3, and the practical application of theoretical weight and the actual weight of the tower
Steel will appear deviation in the rolling process, usually, manufacturers will be the deviation control for negative deviation allowed by national standards, also has the control measures are not good, become a positive deviation. So there is a certain difference between actual and theoretical weight weight.
