Mirror Polished Food Grade Stainless Steel Bar - 12mm Round, NSF
Standard Compliant
NSF-certified mirror-polished stainless steel bars (12mm round) are designed for hygienic and corrosion-resistant
applications in food processing, pharmaceutical, and beverage
industries. Crafted from premium 304/316 stainless steel, these
bars feature a flawless mirror finish (Ra ≤0.4μm) that minimizes
bacterial adhesion and simplifies cleaning. Compliant with NSF/ANSI
51 standards, they are ideal for direct contact with food, ensuring
safety and durability in high-moisture or acidic environments.
Precision-ground to 12mm diameter (±0.05mm tolerance), the bars
offer exceptional strength, heat resistance, and aesthetic appeal
for machinery, conveyor systems, and kitchen equipment.
