Import Blue Limestone — Buy in Bulk from Supplier in China

Blue limestone is a dense, fine-grained sedimentary rock quarried in China, valued in B2B markets for its compressive strength of 60-180 MPa (typical for this grade) and distinctive blue-grey colouration caused by iron and organic impurities. Xiamen Zexian Trade Co., Ltd. offers this material in slab, tile, and block forms, with finishes including honed, polished, and bush-hammered surfaces. The stone's bulk density typically ranges 2.5-2.7 g/cm³, and it absorbs 0.5-3.0% water by weight, depending on porosity and finish treatment. These figures are standard for Chinese blue limestone and should be confirmed with the supplier for the specific lot.

The material composition is primarily calcite (CaCO₃) with minor dolomite and trace minerals that produce the characteristic blue tone. Chinese blue limestone typically contains 95-97% calcium carbonate, with the balance comprising magnesium carbonate, silica, and iron oxides. Finishes affect performance: honed surfaces offer moderate slip resistance (typical friction coefficient 0.4-0.6), while polished surfaces reduce porosity and enhance colour depth but become slippery when wet. Bush-hammered finishes create a textured, anti-slip surface suited to external paving. The stone's natural variation in veining and fossil content means batch consistency requires specification at order stage.

Primary buyers include landscape architects, commercial developers, municipal contractors, and stone fabricators serving residential and hospitality projects. Typical applications cover external paving, pool surrounds, stair treads, wall cladding, copings, and memorial stonework. The supplier's location in Xiamen, Fujian Province, places it near China's major stone processing hub and export port infrastructure. Buyers should confirm MOQ, slab sizes, thickness tolerances, and Incoterms directly with Xiamen Zexian Trade Co., Ltd., as these are not specified in the source data.

Xiamen Zexian Trade Co., Ltd. is located at Unit 210, No. 297-2, Jiahe Road, Siming District, Xiamen, Fujian Province, China, 361012.
