DETAILS OF STEEL TOWERS. Steel towers are commonly made with four columns, 

 although eight or twelve columns are sometimes used for large elevated tanks. The columns of 

 u commonly made of two channels, laced top and bottom; of two channels with top

 in.i.lo of rods with adjustable clevises or turnbuckles. 



EXAMPLES OF STEEL STAND-PIPES AND ELEVATED TANKS ON TOWERS. The
