Our unidirectional chain stitch is the strongest stitch for horizontal seams in the market today. This stitch will flex and resist breaking for a longer period of time than other manufacturing techniques. Our poly sateen heading is the whitest, strongest in the industry, we use a heavy nine ounce polyester sateen material. On flags 15'x25 and larger, we use webbing that is 3 times as strong as any seat belt. Construction begins with finest fabrics and color-matched threads available. We then carefully assemble each flag using a full  turn on all seams, a unidirectional chain stitch for all horizontal seams (it makes the flag stronger), and a lock stitch for all edge hems. Fly hems are finished with 4 rows of lock stitching and a 102 stitch X-Box reinforcement at the top and bottom of flags up to 6'x10. Flags 8'x12 and larger feature an X-box at each horizontal seam. Sizes 10'x15 and larger have 6 rows of stitching on the flyend with double X-box reinforcement on every seam.
