In 1970 Portland Stone Ware began fabricating the Portland concrete filled column. After being approved by ICC-Evaluation Service Inc in 1993, the 16 gauge Portland Columns and caps have been code compliant. Since the year 2000, 16 gauge Portland Columns have undergone a physical plant inspection and certification annually from an independent auditing company hired by ICC-Evaluation Services. Please “See ICC-ES Legacy Report No. 93-36.02” for details, installation information, and compressive strengths for 3½” and 4” diameter 16 gauge steel columns and plates.
Portland Columns are used as structural members to transfer axial compressive loads, from steel or wood beams, to footings. Please note Portland Columns strength is copied below in Table 1 from our ICC-ES Legacy Report No. 93-36.02. The unit of measure is in kips which is a unit of force used by architects and engineers to measure engineering loads. One kip is about 1000 pounds.
