Your Stainless Steel Supply Partner in Northern California
As a steel and aluminum metal supply company for the Bay Area, Reliance Metalcenter specializes in processing and distributing stainless steel materials for OEMs and Tier 1 suppliers. Our stainless steel product offering includes:
304 Stainless Steel
304 is the most commonly used stainless steel alloy due to its excellent corrosion resistance, formability, and weldability. It is suitable for a wide variety of commercial and industrial applications.
We offer:
- 304 stainless steel sheet
- 304 stainless steel plate
- 304 stainless steel coil
- 304 2B coil and 304 2B sheet (cold rolled, smooth matte finish)
- 304 #4 coil and 304 #4 sheet (brushed finish for architectural use)
These materials are commonly used in food handling equipment, kitchen appliances, structural fabrication, tanks, enclosures, and marine components.
Stainless Steel Finishes: 2B and #4 Options
304 stainless steel is available in two popular finishes that serve distinct purposes:
304 2B Sheet and Coil
This cold-rolled finish features a smooth, matte surface that is ideal for forming and fabrication. 304 2B sheet and 304 2B coil are used widely in industrial, structural, and enclosed applications.
304 #4 Sheet and Coil
This brushed finish is often used in architectural, kitchen, and decorative applications where appearance and scratch resistance are important. 304 #4 coil and 304 #4 sheet provide a sleek, directional grain that enhances visual appeal while maintaining durability.
Reliance Metalcenter offers both finish types in coil, sheet, and plate form and can apply protective PVC coatings to preserve surface integrity during handling or fabrication.
316 Stainless Steel
316 stainless steel is an austenitic chromium-nickel stainless alloy with added molybdenum. The molybdenum content enhances corrosion resistance, particularly in chloride or saltwater environments. It is the preferred choice for applications exposed to moisture, chemicals, or high purity conditions. We stock:
- 316 stainless steel sheet
- 316 stainless steel coil
All grades are available in multiple finishes and thicknesses, with full traceability and documentation available for DFAR and industry-specific compliance.
