The Southern Pressure Treaters’ Association (SPTA) was chartered in New Orleans, Louisiana in 1954. Our members supply vital wood components for America’s infrastructure.

The Pressure treated wood poles and wood crossarms form the backbone of the electrical and telecommunications system that delivers electricity, phone, cable and internet to our homes and workplaces allowing us to experience a standard of living unparalleled in the world.

Pressure treated timber piles continue to be the mainstay of foundation systems. Whether it’s a manufacturing plant, airport, commercial building, processing facility, home, pier, wharf, bulkhead or a simple boat dock, timber piles remain the economical and environmentally friendly choice.

 Manufacturers of  these and other industrial treated wood products are located on the About and the Sources of Supply pages.
