Recently I bid on a job that called for 15 concrete piers, each 30 in. high. The loads involved weren’t much — about 100 lb. per pier, so the job didn’t require the bearing or expense of a standard 10-in. column. In addition, large-diameter columns would have appeared too massive for the job.
I used corrugated metal siding to form these short columns. It’s available in various lengths, widths and gauges. The siding I used has 1-in. deep corrugations that are 2 in. wide, spaced 10 in. apart. When I rolled up a section of the siding, it formed a column about 8 in. in diameter with three 2-in. flutes. I held these sections fast by securing the overlapping metal with three short sheet-metal screws.
