Extra Large Characters

Custom Large Character Marking: High-Visibility, Permanent Solutions for Heavy-Duty Manufacturing

In heavy industries like steel fabrication, oil & gas, construction equipment, and large-diameter pipe manufacturing, identification marks must be bold, readable from afar, and withstand extreme conditions—sandblasting, painting, weathering, and decades of service. Faded inkjet codes or shallow laser marks often fail these tests, leading to compliance issues, rework, and traceability breakdowns.

At Numberall Stamp & Tool Co., a family-owned American manufacturer since 1930, we deliver non-automatic large character marking heads engineered for deep, indestructible indent marking.

Our Model 270P stands out as the rugged, manual-indexing solution for applications demanding massive 3/4″ (and larger custom) characters without the complexity or maintenance of automated systems.

The Model 270P: Built for Real-World Shop Demands

Unlike competitors’ high-tech alternatives, the Model 270P offers pure mechanical reliability in dirty, oily, high-heat environments:

• Extra-Large 3/4″ Characters — Standard five-wheel design delivers bold, high-visibility marks on oversized parts like valves, pipes, and heavy machinery.
• Custom Insert Capacity — Room for up to four static inserts to add logos, safety symbols, or fixed data alongside variable serial numbers—perfect for branding and compliance.
• Manual Pin-Index Rotation — Simple tool-based wheel advancement locks characters securely—no accidental shifts during heavy strikes.
• Hot Stamping Compatibility — Mount in a hot stamp press with foil for color-filled impressions that stand out in low-light conditions.

These features ensure deep, permanent indentation that survives post-processing and harsh field use—critical for DOT/OSHA compliance on gas cylinders, structural steel, or heavy equipment.

Why Choose Numberall Over Competitors?

Many manufacturers turn to inkjet (e.g., Matthews Marking Systems’ DOD printheads like 8000+ series for large characters), dot peen (e.g., MECCO’s N-34 deep markers, Pryor’s InDot systems), or automated solutions from GT Schmidt, Columbia Marking Tools, or Pryor. While these excel in speed or automation, they often fall short in rugged permanence and simplicity:

Numberall’s indent marking provides unmatched permanence—no fading after painting or exposure—while eliminating downtime from tech failures. It’s the ideal choice when reliability trumps automation speed.
