SIAM-INDO

What SIAM-INDO does

SIAM-INDO is an Indonesian building materials manufacturer established in 1996, operating through two legal entities — PT. Siam-Indo Gypsum Industry (gypsum products) and PT. Siam-Indo Concrete Products (fiber cement products). The company runs manufacturing facilities in Cibitung/Bekasi (gypsum boards and plasters) and Karawang, West Java (fiber cement planks), with a headcount in the 251–500 range. Its primary commercial brand is ELEPHANT®, supported by sub-brands STAR BRAND® (export line), E'FRAME® (metal framing), QUICKWALL™ (drywall systems), and ELEPHANT WOODPLANK® (fiber cement wood alternatives). The portfolio also includes SMARTFLOOR fiber cement flooring and a SAFEZONE system solution category.

The company's core technology centers on gypsum board and fiber cement manufacturing with proprietary product-level features: Sag Resistant Technology, Mold Inhibitor (ASTM G21 grade 1), fiberglass-reinforced fire-resistant cores, ECHOBLOCK perforated acoustic boards with fleece backing, and the QUICKWALL™ bonding plaster systems. Product breadth spans Standard, Premium, Fire Resistant, Moisture Resistant, Mold Resistant, and acoustic gypsum boards; casting, joint-cornice, and bonding plasters; concealed and exposed-grid ceiling systems; single-layer, double-layer, and party-wall partition systems (with certified fire resistance up to 120 minutes and STC ratings up to 55 dB); plus a complete accessory line (screws, tape, corner beads, access panels, shadow lines). The fiber cement line includes textured, plain, and DEEP COLORED woodplank variants designed as termite-resistant, weather-adaptive alternatives to natural tropical hardwood.

SIAM-INDO operates a sales-led, direct-to-project go-to-market model in Indonesia, supported by long-standing distribution partners (e.g., PT. Gipsindo Grahatama since 1996, PT. Decoplaster Larastama) and WhatsApp consultation channels. Enterprise customers include major Indonesian developers and operators — PT. Summarecon Agung, PT. Agung Sedayu Group, PT. PP Property, PT. Trans Property, PT. Elite Prima Hutama, Kawan Lama Group, PT. Pakuwon Jati, and PT. Bumi Parama Wisesa — across residential, hospitality, retail, and industrial use cases. International distribution under STAR BRAND® targets Southeast Asia and the Middle East. Pricing is project-based and not publicly disclosed; the company has not raised external funding rounds and remains privately held under founder/management control.
