Apache Stainless Equipment Corporation is a commercial manufacturer of capital equipment for other manufacturing businesses. We have five synergistic product groups: Stainless ASME Tanks, Carbon Steel Tanks and Equipment, Small / Portable Vessels, Contract Manufacturing and Mepaco Food Processing Equipment. Founded in 1975 in the growing community of Beaver Dam, Wisconsin, Apache employs over 180 dedicated people who are experienced craftsmen, technicians, engineers or managers. Many of whom are cross-trained to move fluidly between fabrication processes, welding and assembly, as well as having the ability to work across different product lines, which elevates the expertise of our craftsmen and allows our production capabilities to be more agile to meet delivery schedules. As a 100% employee-owned company, Apache's employee-owners are fully empowered to collaborate, innovate, improve processes and create efficiencies because every employee-owner knows that a positive experience for our customer affects our company in a positive way.

Core Competencies / Capabilities Our customers come to us because of our quick response time, on-time delivery, capacity and breadth of capabilities in stainless and carbon fabrications. We specialize in offering custom solutions to our customer's applications in a variety of markets. We service commercial building, water purification, food service, power generation and the tool storage industries. We also supply high- quality, value-added fabrications to the agriculture and heavy-duty truck markets. Materials - Stainless and other high alloy materials - 304 / 316, Hastelloy, and carbon steel from 0.024" (24 gauge) to 0.750" thicknesses. Welding - Our ASME certified welders are specially trained to ensure overall quality, uniform welding and full traceability of certified materials. Material Polishing - We are capable of mechanically polishing to ASME surface designations of 2B-320 grit. We also specialize in electropolishing to ASME surface designations of SPW4-SFW6. Secondary Finishing - We are one of only a handful of companies that maintains an Electropolishing System within its facility. This advanced finishing process gives materials a microscopically smooth surface for improved cleaning, sterilization and corrosion resistance. We also specialize in and offer Pickle Passivation; a finishing process that improves and enhances the formation of the natural corrosion-resistant molecular layer found within stainless steel. Laser Cutting - Our facility uses two 4000 watt laser cutting systems. Specifically designed to handle 3/4" thickness capacity and pattern sizes up to 120" x 156", we offer one of the largest cutting tables in the area. One system features a rotary axis which can be employed to meet several tube and bar cutting requirements. Turret Punch Press - 60" x 100" with work-piece reposition capability, 33-ton punching capacity and up to 5/16" mild steel. Brake Presses - We have three brake presses on site. Our 350-ton and240-ton presses can each handle jobs up to 168" long and our 150-ton press has a maximum working length of 120". Gantry Drill - Our Gantry Drill is used specifically for the manufacture of heat-exchange tube sheets. Table size is 96" x 96" with a 20" z-axis travel and through-spindle coolant delivery. Custom Fabrication - Our team of professionals create exceptional value within the stainless and carbon steel fabrication markets by producing a variety of high-quality components, sub-assemblies and complete final assembly work. We offer wet paint and powder coated surface finishes. Our specialty is low volume production in a wide range of applications.
