We build to order ASME tanks for diversified industries.
Those industries include rail, oil and natural gas, air drying, filtration and purification, and abrasive blast and paint.
What We Do
Where We Are
We are located in Reading Mines, a mining village built for employees of the Philadelphia & Reading Coal and Iron Co. The nearby bituminous coal mine was in operation from the 1890s to the late 1940s.
Our original fabrication shop, the "upper shop" as we say, is three bricks thick and the only structure remaining from the mine's heyday.

Who We Are
Our company was originally established in 1958 by Calvin Zufall and partner Clifford Sible as Z & S Manufacturing Co. In 1960, Z & S Manufacturing Co. was reincorporated as Stoystown Tank & Steel Co.
Initially, the company built oil storage tanks for homes in the surrounding area. By the mid-1960s, it had ventured into manufacturing ASME tanks for EMGLO.
Upon the death of Calvin Zufall in 1980, his son and partner Stephen Zufall, assumed full ownership. During his tenure, the company developed expertise in custom ASME tank design and fabrication.
In 2017, Stephen Zufall retired and Stoystown Tank & Steel Co. became a third generation company as ownership passed to his son Zachary Zufall.
