About Us 

We are a diverse team of multidisciplinary professionals with over 50 years of collective business ownership, engineering, R&D, shop-floor fabrication experience driven to help customers solve their most challenging process and production issues on time and on budget.

Incorporated in 2009, P.W. Custom Fabrications was acquired in 2014 by George Foss, the former owner of 3L Filters, a highly successful Canadian custom fabrication company with North American reach. Key to 3L’s success was the assembly of a qualified and knowledgeable team and its reputation as an innovative, one-stop supplier for customers. This same approach has been implemented with the acquisition of PW and the integration in 2015 of Pro-Tech Manufacturing (general machining and fabrication).

Since acquiring PW, George has developed new markets by producing complete systems for customers in both the aviation and food Industries. PW’s ability to shear, form, polish, machine, weld and assemble metal products in its facility provides a significant advantage over many of its competitors.

Of key interest – George and the PW partner team have developed a highly innovative, patent-pending pressure vessel ‘quick-access’ closure which has significant market potential in multiple sectors, including: oil and gas, mining and water. While in its development, this innovation has garnered the attention of numerous field trial customers and has earned several new TSSA designations.

Meet The PW Team

George Foss, B. Admin, CMA


An inventor at heart, George combines his passion for innovating environmentally sustainable technologies with his desire to understand customer needs. George brings over 35 years management and ownership experience of Ontario-based engineering and manufacturing companies with global operations and customer markets. Leading the PW team, George excels at growing profitable manufacturing companies. Prior to taking over P.W. Custom Fabrications in 2014, George co-owned and operated 3L Filters, a global supplier of engineered filtration, separation and recovery technologies to nuclear, oil & gas, industrial water and aviation markets. Managing a team of 80 employees across three plants in both Canada and the US, George’s leadership resulted in the introduction of innovative filtration and separation technologies to some of the largest companies in the world.


P.W. Custom Fabrications has built its core business infrastructure on speciality fabrication – pipe, vessel and skid filtration, separation and recovery systems. We reinvest in our R&D programs and infrastructure to introduce new resource- and cost-saving technologies, processes and products to our valued customers.

PW’s pressure vessel and power piping business is complemented by a new line of speciality stainless steel pressure vessel ‘quick-access’ closures’, available in 18” to 36” diameters. We are capable of supplying complete vessels with internals for bag or cartridge media. In addition, we also offer quick-access closures as stand-alone ‘fittings’ for refurbishment of existing vessel head-lift closures.

An Advanced Water Technologies partnership in 2018, between Southern Ontario Water Consortium, PW and McMaster University has led to the development of innovative electrochemical-based technology for treating complex mixed-chemical industrial waste water streams. This technology, which will be branded under PW’s new subsidiary company – The Liquid Recovery Group (LRG) – is currently in field trial development with a major North American industrial customer, and will be available to the market in early 2020.
