What CSR does

CSR Limited is an Australian and New Zealand building materials manufacturer founded in 1855/1856 and headquartered in North Ryde, Sydney. The company operates a multi-brand portfolio of 12 wholly-owned subsidiaries plus a joint venture interest in the Tomago Aluminium Smelter, producing integrated building solutions across six application categories: exterior facades (Cemintel fibre cement, Hebel AAC panels), interior solutions (Gyprock plasterboard range including acoustic, fire, moisture, and impact variants), flooring (Hebel PowerFloor), roofing (Monier terracotta and concrete tiles), insulation (Bradford thermal and acoustic products), and structural systems (AFS permanent formwork, Rediwall). The portfolio is sold under long-established brands that, per company disclosure, are specified in 90% of Australian homes, supported by 170+ manufacturing, distribution, property, and office sites and approximately 2,550 employees serving 18,000+ customers across Australia and New Zealand.

The business model combines B2B specification-driven enterprise sales targeting architects and designers (via CPD programs, the System Selector tool, and the iDesign visualization platform) with B2B trade sales to builders and contractors through Trade Credit Accounts, Trade Cash Accounts, the CSR Connect B2B portal, Gyprock Trade Centres, and brand-specific e-commerce storefronts. Reported revenue across FY2020–FY2024 ranged from approximately $1.36B to $1.75B, with FY2024 revenue near $1.71B, and the company delivered 50-year colour guarantees on Monier terracotta tiles and energy-efficiency outcomes through Bradford insulation as documented value propositions. Following a 2025 strategic alternatives review driven by a 30% NAV discount, CSR was acquired by Saint-Gobain for approximately $4.3 billion (AUD) in 2025, becoming a wholly-owned subsidiary of the global light and sustainable construction group.
