HL black limestones are Hard Limestones whose color are dark blue to black, which are exclusive exporting products of SHA Vietnam Co., Ltd in cooperation with Anh Thang Co., Ltd. The hardness of HL dark stones is so high that we can produce large 1.5mm thick flamed stone products such as 40 x 40 cm, 50 x 50 cm, 60 x 60 cm with low broken rate in the production process. The hardness of the product was also demonstrated during the completion of the Black Honed Gothic stones, sizes of 40 - 60 x 8 x 1.5 cm, 60 x 60 x 1.5 cm with a low broken rate during vibrating process. HL black limestones are especially suitable for production of black polished, black honed when achieving extreme black. HL black limestones are also particularly suitable for Black Honed Gothic products while retaining the black background combined with the white scratches generated by the Vibrating process for perfect product surface.
