ZLIN's RGB Gas Range is made of a proprietary black stainless steel that is sure to ignite your culinary experience. Each piece is hand cut and crafted utilizing premium grade stainless steel which accomplishes its sophisticated piano black finish through a technique called PVD (Physical Vapor Deposition) Coating. Also known as sputtering, this technique utilizes a vaporization process to create an atom-bonded, strong ceramic layer in order to achieve its stunning black stainless shine and built-to-last quality. The PVD ceramic layer is composed of abrasion-resistant material, ensuring that its pristine finish will be enjoyed for years to come. ZLINE is synonymous with quality and craftsmanship, which is why each model includes Italian burners delivering over 44,000 BTU's and a durable, solid-piece cast iron grate finalizing its industrial design. Enjoy modern advancements with a highly efficient self-clean capability and a built in exterior timer to help keep you on track. ZLINE continues to revolutionize the industry by providing our customers with Attainable Luxury®. ZLINE proudly stands by the longevity and durability of their ranges alongside its 1 year manufacturer parts & service warranty. The RGB ships next business day when in stock.
