What Dong Tam Group does

Dong Tam Group (Công Ty Cổ Phần Đồng Tâm) is a 57-year-old Vietnamese building materials conglomerate founded June 25, 1969 by Võ Thành Lân and headquartered in Tây Ninh, Vietnam. The company manufactures and distributes a comprehensive ecosystem of construction and finishing products — ceramic and porcelain tiles, handcrafted mosaic tiles, sanitary ware, uPVC and aluminum doors, water-based paints, ready-mix and precast concrete, and colored roof tiles — serving individual homeowners through company showrooms and dongtamshop.com, and construction contractors through a nationwide authorized dealer network.

Technically, Dong Tam applies differentiated manufacturing processes including Nano Coating Technology (a 1-nanometer surface layer applied during polishing for stain and micro-scratch resistance), Double Charge Technology (two-layer simultaneous pressing for decorative porcelain tiles), and Multi-Face surface technology for design variation. Product lines meet international standards including ISO 13007-3:2010 (GROUTEX grout) and JIS K 5663:2003 (paint). The core manufacturing portfolio is supplemented by affiliated distribution (e.g., Indonesian glass tiles) and branded installation accessories — Gecko tile adhesive, Aquaseal waterproofing, and Assure wall putty.

The business model spans three revenue streams: (1) building materials manufacturing and sales through retail showrooms, dongtamshop.com, and wholesale dealer channels; (2) industrial real estate and port operations via wholly-owned subsidiary Cảng Quốc tế Long An (Long An International Port) and the Đông Nam Á Long An Industrial Zone, which lease land and provide logistics services to manufacturing tenants including Hòa Phát Steel and QuickPack Group; and (3) education through Vietnam-Japan Vocational College. The group leverages brand heritage (Vietnam National Brand, Top 5 most reputable VLXD company for 6 consecutive years, HVNCLC 2026) across multi-channel marketing — content/e-catalogue, social media, Vietbuild trade shows, and PR — with pricing administered through retail (niêm yết) and dealer programs without public disclosure.
