Mirror Stainless Steel Sheet | 8K, 10K, 12K, 14K Options

Sanmei Metal provides a full range of mirror-polished stainless steel sheets, from 8K (standard polish) to 12K (diamond-like brilliance) and 14K (hand-polished ultra-mirror). Each grade offers distinct surface clarity and reflectivity, allowing you to choose the perfect finish for your architectural, decorative, and appliance applications.

What make us stand out

Sanmei Metal's 8K Mirror vs. Typical 8K Sheets

Sanmei’s 8K mirror stainless steel sheet delivers premium visual clarity and surface consistency, achieved through advanced coil-to-coil polishing on cold-rolled 2B or BA substrates. Our sheets are widely used in architectural, decorative, and commercial interiors that demand not only aesthetics but also durability.

Why Choose Sanmei Metal

About Us

Verified Material Sources & Traceability

Material quality starts at the source. Verified mills and processors in Foshan ensure traceable, consistent supply.

In-House Color & Surface Processing

Coloring and processing under one roof. PVD, water plating, and surface finishing — all in-house.

Engineering Support Built on Material Understanding

Built on material understanding. Engineers review drawings to ensure profiles are manufacturable.

Integrated Processing & Project Coordination

Coordinated, not fragmented. Processing, fabrication, and finishing aligned end to end.

Mill Guarantee & Quality

Base coils come from our TOP partner mills (Lisco, Tisco, Jisco, Posco PZSS, Yongjin, Hongwang) before undergoing surface finishing and coating in-house at our Foshan facility.

Know More Our Top Resources →

Laser-Grade Film Protection

Every sheet and coil ships with protective PVC film from Polifilm (Germany) and Novacel (France). Adhesion level is matched to your downstream process — strong enough to stay in place through laser cutting or stamping without gas pressure lifting the film and causing edge blowout, but not so strong that it leaves residue when removed.

Global Logistics & Packing

Seaworthy packaging using sturdy wooden crates or steel frames to ensure 100% surface perfection upon arrival. Exporting directly to North America, Europe, Middle East, and Southeast Asia.
