The company operates through three principal product lines: Granite, including crushed granite stones of assorted aggregate gradations, stone dust, railway ballast, and riprap armor stones for coastal and riverbank reinforcement; Limestone, comprising crushed limestone aggregates, base course materials, and fine-grade limestone used in ready-mixed concrete production, asphalt mixing plants, and cement manufacturing; and Dolomite, supplying crushed and pulverized dolomite minerals utilized in float and container glass manufacturing, iron and steel smelting, agricultural soil pH adjustment, and wastewater treatment processes. In addition to quarrying and mineral processing, Stone One provides integrated logistics and transportation solutions, delivering industrial stone, aggregate, and sand directly to client job sites, ready-mix batching plants, and industrial processing facilities. The company conducts extraction and processing operations across major strategic sites, including the Nong Kha Quarry in Chonburi Province, serving infrastructure, civil engineering, and commercial developments across the Eastern Economic Corridor (EEC); and the Chom Bueng Quarry in Ratchaburi Province, operated in conjunction with subsidiary Ratchaburi Enterprises Co., Ltd., supplying limestone and dolomite across western and central Thailand. Founded in 1996, Stone One Public Company Limited is headquartered in Bangkok, Thailand.
In recent developments, the company successfully completed its initial public offering (IPO) and commenced trading on the Market for Alternative Investment (mai) of the Stock Exchange of Thailand under the ticker symbol STX on April 26, 2024. Proceeds from the offering have been deployed toward expanding mineral extraction concessions, acquiring advanced crushing and screening equipment, upgrading logistics capabilities, and funding working capital requirements. To support long-term revenue growth and secure mineral reserves, Stone One has advanced the commercial development of its Khao Yoi quarry project in Phetchaburi Province to expand production capacity for civil infrastructure and industrial consumers. Additionally, the company has broadened its sustainable mining frameworks, securing Green Industry Level 3 certification from the Thai Ministry of Industry and implementing emissions-reduction initiatives in alignment with long-term corporate governance and environmental standards.
