Overview

Plasma cutting is a fast, cost-effective way to cut metal plate and sheet using a high-temperature ionized gas (plasma) arc. Plasma cutting is especially useful for thicker material and general-purpose plate work where strength and productivity matter more than ultra-fine edge cosmetics.

As experts in plasma cutting and fabrication, we handle a wide range of plasma cutting jobs, from base plates and brackets to structural components that move into bending, welding, and machining. We frequently work with customers to refine material, plate thickness, hole sizes, and edge conditions so plasma cut parts perform well in the final assembly and stay within budget.

Advanced expertise & equipment

As a metal fabrication company, we use CNC plasma cutting systems and experienced operators to deliver consistent, repeatable plasma cut parts.

Our plasma cutting capabilities include:

  • CNC plasma cutting for plate, tabs, and structural components
  • Efficient nesting to maximize material usage and reduce scrap
  • Cutting profiles that feed directly into forming, welding, and machining
  • Ability to support both prototype quantities and production runs
  • Integration with in-house laser cutting, bending, welding, abrasive blasting, and powder coating

By combining CNC plasma cutting with our broader fabrication and finishing capabilities, we can take plate from raw stock to finished, ready-to-install parts with one partner.

We know the power of quality.

We synchronize our precision metal work with the highest quality of customer service, while using state-of-the-art technologies that provide customized metal fabrication solutions to fulfill our customer needs.

Frequently asked questions

What is plasma cutting?

Plasma cutting is a process that uses a high-temperature, electrically conductive gas (plasma) to cut through metal plate and sheet. In plasma cutting, an electrical arc forms between an electrode and the workpiece, creating a concentrated jet that melts and blows away the metal along a programmed path. CNC plasma cutting combines this process with computer control for repeatable, accurate cuts.

Plasma cutting is a good choice when:

  • You are cutting mild steel or similar materials in plate and thicker gauges
  • Edge appearance can be cleaned up or is less critical than strength and throughput
  • You want a cost-effective process for structural and general-purpose plate work
  • Parts will be welded, bolted, or assembled where minor edge cosmetics are acceptable

For thinner, highly cosmetic parts with very tight feature detail, laser or fiber laser cutting may be recommended instead.

We use plasma cutting to produce:

  • Base plates and mounting plates
  • Structural tabs, gussets, and connection plates
  • Brackets and stiffeners
  • Components that feed into structural steel fabrication and welding
  • General plate parts for agricultural, industrial, and structural applications

These plasma cut parts often move directly into our bending, welding, and finishing operations.

Plasma cutting is commonly used for:

  • Mild and carbon steel plate
  • Many structural steel profiles and plate products

If you have a specific grade or type of plate in mind, we can review it and confirm whether plasma cutting is the best process for your job.

Plasma cutting is typically used for medium and thicker plate where it is more economical than other processes. Exact thickness ranges depend on material and part geometry. When you submit your RFQ, include material and thickness so we can confirm current plasma cutting capacity.

Yes. We support one-off plasma cut parts, small batches, and full production volumes. Plasma cutting works well for both prototypes and repeat structural or industrial parts.

Preferred file formats for plasma cutting quotes are DXF, DWG, STP and PDF. 

Providing clean flat patterns or clearly defined profiles helps us quote plasma cutting work quickly and accurately.

Typical plasma cutting tolerances depend on plate thickness, feature size, and part geometry. Plasma cutting usually has looser tolerances and more edge taper than laser cutting, but it is very effective for many structural and general plate applications. When we review your drawings, we will confirm realistic tolerances for your specific project.

In general:

  • Plasma cutting is well suited for thicker plate and structural work where edge cosmetics and ultra-tight tolerances are less critical, and cost per part is a primary driver.
  • Laser and fiber laser cutting are often preferred for thinner material, very fine features, and applications requiring cleaner edges and tighter tolerances.

We can help you decide whether plasma cutting, laser cutting, or fiber laser cutting is the right fit based on material, thickness, and design.

Plasma cutting pricing is influenced by:

  • Material type and plate thickness
  • Total cut length and number of pierces
  • Part complexity and number of small internal features
  • Nesting efficiency and sheet/plate utilization
  • Any secondary operations such as beveling, grinding, forming, welding, or coating

We can often suggest small design or nesting changes that reduce cut time and material waste.

Yes. Plasma cut parts are frequently used in structural steel fabrication, frames, and welded assemblies. We can plasma cut plates and components, then move them directly into welding, machining, and finishing for a complete structural or fabricated solution.

After plasma cutting, parts can be:

  • Used as-cut for non-cosmetic applications
  • Welded into larger structures or frames
  • Cleaned and prepped for painting or coating
  • Abrasive blasted and powder coated in-house for a durable finish


If your project has specific coating, color, or surface prep requirements, include those details with your RFQ.
