Is Silestone the biggest quartz producer?

The question is Silestone the biggest quartz producer? is a relevant one. In fact many people discuss this topic. In truth to actually achieve the title of the biggest, we really need to breakdown all the information. Many engineered stone plants have several production lines, and some even have different engineered stone plant systems, so I've made a list based on my personal knowledge and all the available information.
I'm only going to evaluate the companies in the world that use Italian technology, as the Chinese brand has several plants in China which is difficult to give actual data about them.
Quartz Based Producer that use Italian technology:
  • Silestone: they publicize that their the biggest in the world, I figure they should have 11 or 12 production lines installed
  • Santa Margherita produces about 8.000 sqm every day, I assume it includes marble and quartz based material, as they have both plants operating in the same location.
  • Compac, The Surface Company has a marble based plant in Spain and a Quartz plant in Portugal assumes it has a capacity of 2.5 million sqm per year;
  • Quarella-Verona Italy, says it's the biggest agglomerate producer in the world with a yearly output of 4 million sqm, basically they have marble based plant and quartz based plant. Adding up the marble and the quartz capacity it's probably the biggest in the world, so they say. I have not mentioned Rover or Prestige, as I figure their productions are included in the numbers above.
  • Caeserstone - Israel - Says to have a 2 million sqm yearly capacity, they are the oldest company in Quartz based agglomerate, they started their plant in 1987.
  • Çimstone-Izmir Turkey, 2 lines, no quantity specified.

    • Stone Italiana: no available information about production capacity, but one thing I can tell you, their the most expensive in the market, but also the ones who have cutting-edge products.
    • Okite-Italy: no available information on production capacity
    • Diresco-Belgium: capacity to produce 4.000 sqm per day
    • Sidera - Romania: 100.000 sqm per year
    • Technistone - Czech Republic: 2 production lines and are negotiating to double their production capacity
    • Nexus-Germany: just re-started production ... 1 production line
    • Plaza Stone -Russia
    • TotemQuartz -Iran: 1.000 sqm per shift, needless to say that normal production lines work 3 shifts.
    • Gulf Stone- Oman: no available information regarding production capacity;
    • Zodiaq-USA: no available information
    • Vicostone-Vietnam: They currently have 2 production lines, no available information regarding production capacity
    • HanStone - South Korea: no online information available
    • RomaStone - Taiwan: 98.000 sqm per month although they have a block producing plant and mainly deal in marble based material;
    • RMC-Portugal: have a marble block plant and no available information on production capacity;
    • Yunfu Breton Stone Building Materials - China: 1 block plant to produce marble based material output not available
    • Pokarna - India: no available information regarding production output
    So this is about it, hope I didn't miss any Breton Plant for engineered quartz or engineered marble (which use polyester resin as a bonding agent). The answer to the question of this post is: if you just take the engineered quartz part of the business then Silestone is the biggest in the world, but if you add the engineered marble and look at engineered stone or composite stone as some usually call it, then we have Quarella in the top position.

    Hi nice blog. Just few plants are missing from the list.
    Kalingastone , according to my info., does not belong to the list since they have Chinese made machinery.

    Answer to Technical
    Thank you for the comment.
    Actually, I have to check on that, I met up with them in Marmomacc and have traded some e-mails with them. I have and idea that it was Italian technology. I've checked their catalogue and have not found any evidence. I will e-mail them and see what comes up.

    Hi,
    I have heard that in spain many silestone workers are getting silicosis, is it this truth?

    Dear Kotaro,
    I have not heard such thing, however they are at risk, but workers should follow specific safety measures to insure health standards.

    Interesting blog, sorry to say that you missed the only engineered stone producer in the USA (2 lines) and that HanStone has a new plant in Canada. CaesarStone has for lines that are capable of producing 400 slabs per day producing 6 to 7 days a week but more important in my opinion is the percentage of A, B and C grade slabs because that defines for a great part the quality of the proces and imho also of your organization. Companies may show off with their output figures, I wonder if they tell you about the numbers of B and C grade. Some sales people say........they don't have it at all! LOL
