What is waterjet cutting?
Waterjet cutting uses a high-pressure stream of water, often combined with abrasive material, to cut through a wide variety of materials. Unlike heat-based cutting methods, waterjet cutting does not create a heat-affected zone, helping preserve material structure and appearance.
That makes it useful for thick materials, heat-sensitive materials, complex profiles, smooth curves, detailed patterns, beveled cuts, and large-format parts.
Large projects
Take on substantial material sizes with a 10-foot by 20-foot work envelope.
Material flexibility
Support metals, composites, glass, and other materials after project confirmation.
Custom applications
Ideal for prototypes, industrial components, signage, art, and architectural elements.
Steel and metal waterjet cutting in St. Louis
Metal is the core of most waterjet work. Because the cut is made with water and abrasive rather than heat, steel plate and sheet keep their original temper, edges stay free of hardening and slag, and parts come off the table flat and ready for welding, machining, or finishing.
That makes waterjet cutting a strong fit for thick steel plate, stainless steel parts that must stay corrosion resistant, aluminum that would distort under a torch, and any metal part where a heat-affected zone would cause problems downstream. Combined with the 10' x 20' table and 5-axis bevel cutting, it covers everything from small brackets to full-size plates.
- Carbon steel plate
- Stainless steel
- Aluminum
- Brass and copper
- Beveled weld-prep edges
- Thick plate and large blanks
Ideal waterjet cutting applications

Decorative panels, metal accents, building components, and large-format design features.
Intricate shapes, signage, displays, custom art, and one-off creative projects.
Accurate prototypes and early-stage components where flexibility and precision matter.
Thicker material projects where laser cutting may not be the best fit.
Beveled edges, curved components, and 3D-style cutting requirements.
Waterjet cutting questions
Can you waterjet cut steel and stainless steel?
Yes. Abrasive waterjet cutting handles carbon steel, stainless steel, aluminum, and other metals without heat, so edges are not hardened and parts do not warp. The practical thickness limit depends on the material and the edge quality you need, so send the material and thickness with your quote request and the team will confirm.
What makes waterjet cutting different from laser cutting?
Waterjet cutting uses high-pressure water and abrasive cutting power instead of heat, so it avoids a heat-affected zone and can be a strong fit for thick, complex, or heat-sensitive materials.
Can you cut large parts?
Yes. The waterjet cutting table measures 10 feet by 20 feet, allowing St. Louis Water Jet to support large panels, industrial parts, architectural elements, signage, and custom oversized work.
What project details help with a quote?
Material type, thickness, dimensions, quantity, drawings or CAD files, tolerance or edge requirements, and timeline all help the team review the project efficiently.
