Pt 20 – High Strength

PT 20 was designed for use in light commercial and industrial applications. PT 20 is ideal for private parks and schools, warehouses, auto dealerships/parking lots, sports facilities and a wide variety of other applications. It is also ideal for industrial gate framework.

Superior Corrosion Resistance – With our advanced coating process, we guarantee the highest degree of corrosion resistance available. PT 20 features the identical triple layer coating process of our PT 40. A triple layer of OD corrosion protection consisting of a zinc bath, an intermediate conversion coat and a clear vacuum sealed top coat is then added to provide the maximum in protection and durability. The ID is zinc coated prior to forming.

Strength – PT 20 is fabricated to conform to ASTM A 653 with a high yield strength of 50,000 PSI. And because its yield strength is 65% greater and 20% lighter than hot dip galvanized pipe, it is ideal for gate framework.

Made in the U.S.A. – All tubing product is manufactured in the USA meeting BuyAmerica(n) requirements.
