Why Piranha

Why Structural Steel Shops Choose Piranha

Three reasons structural fabricators run Piranha on their shop floor.

P-Series Ironworker · The Structural Flagship

Made in the USA. The P-Series ironworker punches, shears, copes, and notches bolt patterns, base plates, splice plates, and connection plates — the daily-bread work of every structural shop. One station, one operator, six tools.

Heavy Plate That Holds Tolerance

Gussets, splice plates, moment plates, shear tabs, doubler plates — the connection plate work that holds a building together. Piranha LASER and HD plasma deliver weld-ready edges and bolt-pattern precision the inspector signs off on.

One Source for the Whole Shop

Ironworker, Flex Series LASER, Whitney HD plasma, press brake, shear — every machine from one manufacturer, with one quote, one install team, and one parts catalog. U.S.-based phone support that answers.

Shop-Floor Wins

How Piranha Speeds Up Your Shop

Four ways Piranha equipment changes the math on structural steel fabrication.

P-Series · USA
Made-in-USA ironworker — six tools, one station. The daily workhorse of the structural shop floor.
3″ Plate
Whitney HD plasma cuts up to 3″ mild steel — base plates, moment plates, column splices in one setup.
AISC-Ready
Bolt-hole precision and weld-ready edges the inspector signs off on. Built for AISC-certified shop quality programs.
One Setup
Punch bolt patterns and shear blanks on the same ironworker. Cut and bolt-hole plate connections on the same LASER.

Frequently Asked Questions

Common questions from structural fabricators, erection shops, and procurement teams.

How does the P-Series ironworker support an AISC-certified shop quality program?

The P-Series produces consistent, repeatable bolt patterns and clean cope cuts — the kind of work that holds tolerance for AISC inspection. Operators can run base plates, splice plates, and shear tabs to spec without bouncing between stations, which simplifies the quality trace.

What plate thickness can Piranha equipment handle for heavy column base plates and moment plates?

Whitney HD plasma cuts up to 3″ mild steel in one pass — suitable for heavy base plates, column splice plates, and moment connections on big-box, mid-rise, and industrial work. For thinner plate (under 1″), the Flex Series LASER delivers cleaner edges and tighter bolt-hole accuracy.

When does LASER cutting make more sense than plasma for structural connection plates?

LASER wins for gussets, shear tabs, fin plates, and other connection plate work where bolt-hole position and edge quality matter for welding. HD plasma on the Whitney Combo handles thicker plate (1″ to 3″) at faster speeds and lower per-part cost — base plates, large moment plates, doubler plates.

Does Piranha equipment work for a misc-metals shop running stairs, rails, and embeds?

Yes — this is one of the most common structural shop configurations Piranha is built for. Press brake + ironworker + LASER covers stair stringers, stair pans, handrail brackets, embed plates, anchor plates, and ladder components — without the bottlenecks of outsourcing plate work.

What about big-box / pre-engineered building shops — high-volume column and beam runs?

Production LASER + automation + Whitney HD plasma is the configuration most pre-engineered and big-box shops run. Automated material handling on the LASER, plus Whitney HD for thicker base plates, lets a small crew run multi-shift production with consistent quality.

How does this fit alongside a beam line / drill line for full structural production?

Piranha handles the plate prep and connection plate work that feeds the beam line — base plates, splice plates, gussets, moment plates, stiffeners. The combination of Piranha plate equipment + a beam line covers the full structural shop scope. Application engineering will scope the right plate-side configuration for your beam line and part mix.

What's the install timeline for a complete structural fab line?

From signed order to first part: typically 12–20 weeks depending on automation scope, machine count, facility readiness, and electrical/utility prep. Piranha application engineering coordinates with the customer's plant team through every stage.

Do you offer financing for capital equipment?

Yes. Piranha offers flexible financing options for capital equipment purchases — useful for managing structural shop investments across multiple machine orders or staged automation rollouts.
