Precision Tolerance (Cold Drawn)
Unlike Hot Rolled bars, Cold Drawn bars typically hold a negative tolerance (Undersized) to ensure they fit into standard slots/keyways.
Typical: +0.000" / -0.004"
Corners: Sharp / Square
Select Your Grade
Both grades are Dual Certified (Low Carbon) for better weldability.
304 / 304L
The StandardThe most versatile stainless steel. Ideal for indoor applications, machining parts, and dry environments where extreme corrosion resistance is not required.
- ✓ Lower Cost: Budget-friendly choice.
- ✓ Formable: Excellent for bending.
- ✓ Use For: Indoor Brackets, Machinery.
316 / 316L
Marine GradeContains Molybdenum for superior resistance to pitting. Essential for environments exposed to salt water, chlorides, or harsh chemicals.
- ✓ Max Protection: Resists rust/pitting.
- ✓ Durable: Best for long-term outdoor use.
- ✓ Use For: Marine, Lab, Outdoor Trim.
Edge Condition Matters
For precision fitment, the edge profile makes all the difference.
Cold Drawn (True Bar)
Extruded and cold finished through a die. This creates perfectly square corners and precise dimensions.
Sheared & Edged
Slit from a wider plate and edge-conditioned. Results in slightly rounded edges and looser tolerances.
Small Profile, Big Utility
Common applications for 3/8" x 1/2" stainless steel bar.
Machine Key Stock
The cold-drawn "True Bar" finish provides the tight tolerances and square corners needed for machine keys and shaft locking.
Mounting Brackets
Ideal for creating small, corrosion-resistant brackets for sensors, instruments, or shelving in food processing areas.
Lab & Medical
Grade 316 provides the necessary resistance to harsh cleaners and chemicals found in pharmaceutical and laboratory settings.
Architectural Trim
Often polished and used as separation strips in tile work, cabinetry inlays, or furniture accents due to its sleek profile.
Customization Services
We tailor our 12' random length bars to your exact project requirements.
Production Saw Cutting
Don't have a band saw? We can cut full 12' bars down to your specific shipping or production lengths. No minimum piece count.
- Tolerance +/- 1/16" (Standard)
- Method Band Saw Cut
- Edge Deburred / Clean
Polishing & Finishing
Standard bars come in a matte "Mill Finish". For decorative applications (trim, architecture), we offer enhanced finishes.
- #4 Finish Brushed / Satin
- #8 Finish Mirror Polish
- Packaging Fiber / Vinyl Protected
Logistics Advisory
Standard 12-foot bars must ship via LTL Freight. To qualify for UPS/FedEx Ground shipping (and save on freight costs), request your bars be cut to lengths of 6 feet or less.
