The JWF Defense Difference

JWF Industries


In 1957, John Polacek, Sr. found himself working for Bethlehem Steel and struggling to provide for his nine children. To help ends meet he put a welding machine on the back of his pick-up truck and started Johnny’s Welding. When John Polacek, Sr. passed away in 1987, his welding company was located in a two-car garage and had one employee — his son, Bill Polacek. Bill bought the company from his mother and started Johnstown Welding and Fabrication.

As the company grew in size and reputation the name was changed to JWF Industries. Almost 30 years later, JWF Industries has grown into one of the largest metal fabricators in the east with a wide array of capabilities and an excellent reputation in the industry. JWF’s commercial customer base includes some of the biggest OEMs in the United States, Canada, and Europe.

News & Events

JWF Employees Fabricate Strank Memorial


The raising of the flag atop Mount Suribachi during the Battle of Iwo Jima is an iconic photograph from World War II. It became a symbol of the Pacific war zone and is the centerpiece of the U.S. Marine Corps War Memorial in Arlington, VA. The photo was first published in February 1945. Sargent Michael Strank, a native of nearby Franklin Boro. is one of the five Marines depicted in that notable event. Strank’s Franklin Boro. hometown recently was the scene of a Remembrance Ceremony commemorating the 75th anniversary of the flag raising.

The steel sculpture that recreates the infamous scene atop Mount Suribachi was fabricated at JWFI’s Iron Street facility thanks to the design work of Keith Douglas who converted a photo of the event into an AutoCad drawing. The drawing was divided into three pieces and laser cut from 3/16 inch steel and powder-coated.  Bob Rummel was responsible for the fabrication that included building the mounting frame and brackets needed to support the structure from behind.  A concrete footer was  poured at the site with a slot to mount the three pieces. Local artist Richard Hower made the sculpture come alive by painting shading over the top of the powder-coated structure.

Unfortunately Sargent Strank never knew that he would have a place in local and national history. He was killed during heavy artillery fire with the Japanese six days after helping to raise that flag



Environmental Tank & Container

JWF is located in the heart of natural gas drilling on the Marcellus and Utica Shale formations. In response to changing drilling regulations by Pennsylvania’s Department of Environmental Protection office in 2010 that limited the amount of total dissolved solids that could be discharged in waterways, JWF saw an opportunity to develop and manufacture its own products—above ground containment vehicles to temporarily house the fluid while transporting it to water treatment plants. In 2011, JWF began manufacturing a variety of products for the oil and gas industry through a newly created division, Environmental Tank & Container (ETC).

As a manufacturer of Above Ground Impoundments, Frac Tanks, Mud Tanks, Gas Busters and other equipment for the oil and gas, power generation, gas processing, and industrial environmental market, ETC has grown to become one of the biggest names in fluid storage and oilfield equipment.
