Inquiry (采购产品): Steel I beam. I want to use a steel I bean system to finish off a New cement patio. The support lenght will be approx 120ft in linear measurements and up to 1 to 4 ft exposed on a slope terrain. I want to basically figure cost for a post and lental system which I will bring a corrigated steel with a Cenemt pour. I am trying to avoid digging a trench building and pouring a cement retaining wall for the patio to meet. The reason is that there is no access for a truck and I am mixing (with the help of a small mixer) a 120 30 foot cement patio. Can you help with maximum span I can go with the least amount of post going into the ground. The "guestament" of material cost and nearest location to get the material. Thank you in advance.
