PTI envisions a future in which post-tensioning is the first choice for reinforcing all structures.

PTI will promote and advance the post-tensioning industry through education and technical leadership.

Members of the Institute include major post-tensioning material fabricators in the U.S., Canada and Mexico, and manufacturers of prestressing materials in the U.S., Canada, Mexico, Asia and Europe, and companies supplying materials, services and equipment used in post-tensioned construction. In addition, PTI has more than 500 professional engineers, architects and contractors.

PTI has engineering staff available to assist you with any post-tensioning related technical questions you might have about a document or a project. All technical inquiries must be submitted by e-mail. Questions will be answered via e-mail, in the order received, with PTI Member questions having priority.
