PRODUCTS & APPLICATIONS
Our Approach to Every Project Makes a Difference Customers Can Count On
The Right Materials. The Right Fabrication. Reliable Performance
In corrosive industrial environments, equipment performance depends on more than the materials used. Material selection, weld integrity, fabrication methods, and an understanding of the operating application all contribute to equipment reliability and service life.
Application-Driven Material Selection
Different chemicals, temperatures, and operating conditions require different material solutions. We work with customers to understand their application requirements and determine appropriate fabrication materials and methods.
Skilled Welding & Precision Fabrication
The integrity of a fabricated tank depends heavily on the quality of its joints and construction. Our experienced fabricators apply specialized thermoplastic and metal welding capabilities to produce equipment built for demanding service conditions.
Custom-Built Around Your Requirements
Standard equipment doesn’t always meet the requirements of an industrial process. We manufacture custom tanks and components to accommodate specific dimensions, connections, process configurations, and installation constraints.
POLYFAB INDUSTRIAL SERVICES INC.
25 Years of Custom Fabrication in Kitchener, Ontario, Servicing Customers Across North America
Our established manufacturing facility in Kitchener, Ontario, brings in-house design, skilled fabrication, and specialized equipment together under one roof. For our customers, that means fewer handoffs, faster resolution of design and production challenges, and greater control over quality and delivery schedules.
Whether manufacturing a single custom tank or equipment for an entire process line, we have the experience, capacity, and flexibility to meet demanding specifications, control costs, and deliver equipment that’s ready to perform.
CUSTOMER TESTIMONIALS
When Equipment Performance Counts, Experience Matters.
For industrial operators, premature equipment failure can mean more than the cost of replacing a tank. It can interrupt production, increase maintenance requirements, and create unplanned operating expenses. Polyfab works with customers to address these challenges through material selection, custom fabrication, and practical solutions informed by real operating conditions.
