ZLINE 48” Professional Porcelain Rangetop in Black Stainless with 7 Gas Burners - RTB-48

ZLINE's professional black stainless steel is truly unique in the industry. Each piece is hand cut and crafted utilizing 304 grade stainless steel which accomplishes a sophisticated, black finish through a technique called bluing. The technique of bluing has been used historically to change the finish of gun barrels.

The proprietary black stainless steel finish is hand soaked to a specific ratio which depicts the final and exact result of the black stainless hue. The industrial design of the RTB is executed through precise lines and detailing done with a precision laser. Each model includes Italian burners delivering over 65,000 BTU's, including a durable, solid-piece Cast Iron Grill.


  • Handcrafted, high quality Italian burners imported directly from Italy with premium alloy to ensure efficient and clean-burning flames
  • Italian burners are durable and easily detach for a simple clean
  • Heavy duty Italian made porcelain one-piece cook top allows for an easy to clean surface - no crevices that can hold residue
  • No-scratch ceramic designed to handle every cooking environment
  • Solid-piece cast iron grill - heavy duty and built to last
  • Cast iron is extremely durable, with an exceptional strength-to-weight ratio

Love it...

Glad I decided on this... Love it

Steven W.
Pleased with my purchase

Was easy to install and so far so good. I have an older home so finding appliances that "fit" closely to older standards has been an issue. With a little adjustment this cooktop dropped in and installed easily. I had to get some secondary fittings and longer gas line but was part of the upgrade process. My old cooktop was probably 45 years old, so this was a nice addition. Worth buying one im my opinion.

Love our ne cooktop!

Both my wife and I cook and host many large parties and worked in the service industry and are always looking for quality and durability. We were hesitant to buy a stainless cooktop but couldn’t be more happy with this appliance. I was concerned that maybe the BTU’s wouldn’t be adequate for our needs but I was wrong. Very easy to use, quality stainless top is even easier to clean. Love the layout burners which maximizes the cooktop space. Just hosted a party of 25 that went off without a hitch. It is now the center piece of our newly renovated chef kitchen. Highly recommend.
