Channel steel theoretical weight table and channel steel specifications

Channel steel is the most commonly used type of steel in engineering construction. Like angle steel, they are mainly used for corrosion resistance and weight requirements. The theoretical weight calculation of channel steel is also a basic knowledge that engineers must know. This article focuses on the specification of the channel steel and the theoretical weight table of the channel steel.
a) theoretical calculation method of channel steel
The calculation formula of the channel steel (kg/m) W=0.00785x[hd+2t(b-d)+0.349(R^2-r^2)], where:

• h= high
• b= leg length
• d= waist thickness
• t= average leg thickness
• R= inner arc radius
• r= end arc radius

Note: R^2 represents the square of R
