ZLINE's RGB Gas Range is made of a proprietary black stainless steel that is sure to ignite your culinary experience. Every piece of 304 grade stainless steel is hand cut and crafted, where it then undergoes a technique called bluing to achieve a sophisticated, ‚Äúpiano black‚Äù finish. This unparalleled technique involves hand soaking the proprietary black stainless steel finish to a specific ratio that depicts the final and exact result of the black stainless hue. 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 grill 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.
