Each grade offers distinct surface clarity and reflectivity, allowing you to choose the perfect finish for your architectural, decorative, and appliance applications.

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.

- 구매하기 전에 과부하를 피하기 위해 완성된 장식용 시트의 전체 무게와 적용 영역의 하중 지지 용량을 예상해야 합니다.
- 장식용 시트는 주로 미적 목적으로 사용되므로 더 얇은 두께로 충분하여 비용을 절감할 뿐만 아니라 요구 사항도 충족합니다. 실내 또는 실외 사용 여부에 관계없이 스테인리스 스틸 장식용 시트의 이상적인 두께 범위는 0.5mm에서 2.0mm 사이입니다.
- 0.5mm보다 얇은 시트는 너무 취약하여 취급 및 제조 중에 쉽게 손상될 수 있습니다.
- 2.0mm보다 두꺼운 시트는 가공하기 어렵고 실제 응용 분야에 사용하기도 어렵습니다.
