Cold Rolled Stainless Steel Coil (2B Finish) at Factory Price

Cold Rolled Stainless Steel Coils are produced by further reducing the thickness of hot-rolled material at room temperature. This specific manufacturing process creates a denser metal structure with a smooth surface and extremely tight thickness tolerances, making it the perfect choice for high-precision manufacturing and high-end industrial products.

The Excellence of 2B Finish

The 2B finish is the most widely used cold-rolled surface in the industry. It features a smooth, greyish-matte, and semi-reflective appearance. It is ready for immediate industrial use or can be easily and cost-effectively polished to higher aesthetic finishes such as Hairline (No.4) or Mirror (No.8) due to its superior base smoothness.

Why Source Your Coils from Trinity Dynamic?

To optimize your material costs and production efficiency, we operate as a full-service steel center offering more than just raw materials:

Custom Processing (Shearing & Cutting): We provide precision shearing and cut-to-length services based on your exact dimensions, significantly minimizing your material scrap and waste.
Optimized for Automation: Purchasing in coil form is ideal for factories utilizing continuous stamping, punching, or roll-forming machines. It reduces machine downtime and lowers labor costs compared to feeding standard sheets.
Nationwide Transportation: We offer reliable delivery services directly to your manufacturing facility or project site anywhere in Thailand.
Certified Quality: Every coil comes with a Mill Test Certificate (MTC) ensuring compliance with ASTM and JIS standards.

Frequently Asked Questions (FAQ)

Trinity Dynamic supplies 2B finish coils in various grades to meet your specific needs: Grade 304/304L for durable general use, Grade 316L for excellent corrosion resistance against chlorides and marine environments, and Grade 430 for cost-effective indoor applications. We stock thicknesses from 0.4mm to 3.0mm.

Yes, we do. As a comprehensive steel service center, we offer slitting, shearing, and custom cut-to-length services. This allows you to receive the exact dimensions required for your production, eliminating unnecessary material waste.

Absolutely. The cold rolling process gives the 2B finish an extremely tight thickness tolerance and a uniform surface. This ensures smooth feeding into automated stamping and pressing machines without jamming, making it highly popular for kitchenware and automotive parts manufacturing.

2B finish is slightly more expensive than No.1 because it undergoes additional cold rolling processes. You should choose 2B for thicknesses under 3.0mm, applications requiring precise dimensions, or if you plan to polish the surface. No.1 finish is rougher, thicker (3.0mm+), and better suited for heavy structural support.

Yes, 100%. Every batch of stainless steel supplied by Trinity Dynamic includes a Mill Test Certificate confirming its chemical composition and mechanical properties according to ASTM A240 and JIS G4305 standards.

Yes! We provide reliable metal transportation services nationwide across Thailand. Whether your factory is located in an industrial estate or a remote project site, our logistics team ensures your materials arrive safely and on time.
