BA Surface Finish Stainless Steel Pipes & Tubes — AISI 310S/316L Square & Rectangular Profiles
2026/07/16
Introducing Premium BA Surface Finish Stainless Steel Pipes and Tubes
We are pleased to announce our comprehensive range of BA (Bright Annealed) surface finish stainless steel pipes and tubes, available in square, rectangular, and round profiles. Featuring premium grades including AISI 310S and 316L, this product line delivers superior corrosion resistance, exceptional surface quality, and versatile dimensional options for architectural, industrial, and decorative applications worldwide.
Manufactured under controlled atmosphere annealing, the BA surface finish achieves a bright, mirror-like appearance without additional polishing. This makes our pipes ideal for visible installations where aesthetics matter as much as performance — from luxury elevator interiors to high-end architectural façades.

Why Choose BA Surface Finish?
The Bright Annealed (BA) finish is produced through heat treatment in a controlled atmosphere furnace, resulting in a highly reflective, smooth surface that requires no additional polishing. Key advantages include:
- Superior reflectivity — mirror-like appearance ideal for decorative and architectural use
- Enhanced corrosion resistance — uniform passive layer formed during controlled annealing
- Excellent cleanability — smooth, non-porous surface resists dirt and bacteria accumulation
- Consistent aesthetics — uniform finish across full coil length without polishing variations
Featured Grades: AISI 310S & 316L
AISI 310S offers outstanding oxidation resistance up to 1100°C with high chromium (24–26%) and nickel (19–22%) content, making it the preferred choice for high-temperature architectural elements, furnace components, and heat treatment equipment. Its low carbon content minimizes carbide precipitation and intergranular corrosion in welded structures.
AISI 316L provides excellent resistance to pitting and crevice corrosion in chloride environments thanks to its 2–3% molybdenum addition. With low carbon for improved weldability, 316L is widely specified for marine architecture, coastal building projects, chemical processing equipment, and food-grade installations where hygiene is critical.
