Used pieces of galvanized "C channel". They have bolt holes to make them continuous if you desire. Measures channel depth is 6 inches, leg height is about 2 inches, web thickness is 3/16 thick.. 12.5 feet long and weight is 9 lbs per foot so each section is around 112 lbs.
The price is $40 per stick but If you buy a "bundle" of 49 pieces we will offer a discounted price of $1800.
