Quality Inspection for Black Gloss Quartz Countertops - Beautiful Black Mirror Quartz Surface Kitchen worktop China Factory Artificial Stone 2014 – Granjoy

Black mirror color artificial quartz slab, model 2014. Artificial quartz is made of 93% natural quartz, with high-quality resin and pigment. Polished surface, Mohs 7.0, hard and non-porous, worktops or splashback made of quartz is bright and smooth, easy to clean, and anti-virus. Unlike marble or granite, you do not need to seal your quartz tops every year, easy to maintain, save the maintain fee for you. Quartz has been a very popular material for household kitchens, office, and shopping malls, airports, etc.

We are a comprehensive group enterprise with more than ten years of experience in quartz product production and R & D. at present, the company’s main business includes the R & D, production and sales of quartz plate; R & D, production and sales of quartz stone deep-processing products; R & D and production of high-end quartz processing equipment. The products sell well in more than 40 countries and regions nationwide and overseas, and have successively passed ce nsf ISO900ISO14001 and other professional organizations. At present, the group has three major plate production bases: domestic, export and intelligent production, with an annual total output of more than 20million m2.

In recent years, the group has increased investment in scientific research and made breakthrough progress in high-end intelligent equipment and processes in the field of plate production and deep processing. In particular, the new intelligent plate production line not only greatly reduces labor, but also produces quartz stone plates with indicators that exceed those of similar products at home and abroad.

By 2019, the group had obtained 17 invention patents, 23 utility model patents and 32 appearance patents, which had a far-reaching impact and drive in the industry.
