Stainless Steel Surface Finishes for Food-Grade Fitouts: 2B, No.4 & BA Explained
Blog | November 6th, 2025
Why Surface Finish Matters in Food-Grade Stainless Steel
Food-grade stainless steel requires smooth, non-porous surfaces to minimise contamination risks and meet strict health and safety standards. The right finish supports compliance with HACCP standards by preventing bacteria build-up and making surfaces easier to clean. Businesses should consider hygiene, visual appeal, and maintenance needs to ensure long-term efficiency and regulatory compliance.
2B Finish – Versatile and Easy to Clean
The 2B finish is a smooth, matte grey surface created through cold rolling and annealing. Its uniform texture makes it easy to clean, which is vital for food preparation and storage areas. This finish provides an ideal balance between hygiene and affordability, making it a popular choice across industries.
Common applications for stainless steel surface finishes like 2B include food processing equipment, benchtops, and storage racks. Their excellent corrosion resistance protects against moisture damage, which is common in commercial kitchens. This cost-effective option ensures dependable performance without compromising safety.
No.4 Finish – Durable with a Brushed Look
The No.4 finish has fine, brushed parallel lines that offer a professional and polished appearance. This makes it a preferred option for areas where both durability and visual appeal matter. It is commonly used in commercial kitchens and visible surfaces such as splashbacks and panels.
Key Benefits:
• Provides a contemporary, professional appearance suitable for front-of-house areas.
• Resistant to scratches, ensuring longevity in high-use zones.
• Easy to clean, supporting food safety standards and hygiene protocols.
• Offers excellent durability for continuous use in commercial environments.
• Cost-effective balance between function and visual appeal.
BA (Bright Annealed) Finish – High-End, Mirror-Like Shine
The BA finish is known for its smooth, reflective surface that resembles a mirror. It is produced through controlled heat treatment, resulting in a flawless and highly polished appearance. This finish is often chosen for premium food-grade environments where presentation and cleanliness are paramount.
Key Benefits:
• Creates a high-end aesthetic ideal for modern, premium kitchens.
• Simplifies cleaning, reducing bacteria build-up on surfaces.
• Highly reflective surface enhances lighting and visibility in workspaces.
• Resistant to corrosion, maintaining a pristine appearance over time.
• Ideal for decorative or showroom-style applications.
Choosing the Right Finish for Your Food-Grade Fitout
Selecting the most suitable stainless steel surface finishes depends on factors such as hygiene requirements, maintenance frequency, and design preferences. For back-of-house operations, 2B finishes offer reliable cleanliness and efficiency. No.4 finishes suit visible areas where durability and appearance are key, while BA finishes are ideal for premium or high-profile spaces.
