Sway Braces Custom Designed for a Mechanical Equipment Supplier

Type: Fig. 555 Sway Braces
Size: 34-7/8” to 42-1/4″
Material: A36 carbon steel | Hot-dipped Galvanized
Design: 17,827 lb. Ld. | 12″ Travel | 7,200 lb. Spring Rate

PT&P custom designed Fig. 555 sway braces for a mechanical equipment supplier in Canada. The sway braces are fabricated from carbon steel, hot-dipped galvanized and range in length from 34-7/8” to 42-1/4″. The largest sway brace was designed for an operating load of 17,827 lb., a design travel of 12″ in either compression or extension and a spring rate of 7,200 lb. per inch. The smallest sway brace was designed for an operating load of 200 lb., a design travel of 9″ in either compression or extension and a spring rate of 1,800 lb. per inch.

The specified loads and/or movements exceed those of PT&P’s standard sway brace; therefore, these sway braces required a custom design and fabrication. Each sway brace was configured with a unique combination of carbon steel, spring coils, housings and internal components to accommodate the non-standard loads and movements.
