Overview
Alumex is a Sri Lankan aluminium-profile manufacturing company and a subsidiary of Hayleys PLC. It is described as Sri Lanka's leading fully integrated aluminium-profile producer, with activities spanning extrusion, anodizing, powder coating, wood-finish treatment, fabrication, and value-added manufacturing for export markets. The company was established in 1986 as a South Korean–Sri Lankan joint venture and began commercial operations in 1988 with a six-inch extrusion line and an anodizing plant. Its manufacturing base subsequently expanded through larger extrusion capacity, surface-treatment facilities, automated production, and dedicated plants. The business primarily supplies aluminium profiles and related products for architectural, construction, interior, and industrial applications. Its capabilities include standard and customized extrusions, anodized profiles, powder-coated profiles, and wood-finish profiles. The company reports certifications and accreditations associated with quality, environmental management, occupational health and safety, powder coating, and anodizing. It states that its finished profiles can carry warranties of up to 30 years, subject to the applicable product and finish. Ownership changed materially over time. In 2006, the Sri Lankan partners acquired the South Korean partner's interest. Hayleys acquired 95 percent of Alumex for approximately LKR 2.2 billion in 2010, marking Hayleys' first major acquisition of a manufacturing company focused primarily on the domestic market rather than overseas production. Alumex was re-registered as a public company in 2013 and completed an initial public offering in 2014. It became one of the Hayleys subsidiaries listed on the Colombo Stock Exchange. Alumex has continued investing in capacity and automation. A large extrusion plant was established at Makola in 2000, a modern anodizing plant was installed in 2008, and a horizontal automated powder-coating and wood-finish facility was added in 2015. In 2018, the company commissioned an automated plant at Ekala with reported production capacity of approximately 1,000 metric tonnes per month. Capacity expansion at Sapugaskanda and a second wood-finish plant followed. In 2021, Alumex began value-added manufacturing for export markets, broadening its role beyond domestic supply. Sustainability has become part of the company's product and operating narrative. Alumex reports that approximately half of its raw-material input is sourced from recycled aluminium beverage cans. In 2022 it introduced Ozon, presented as Sri Lanka's first low-carbon aluminium brand, using environmentally oriented manufacturing technologies. The company has also described an Elevate ESG roadmap covering sustainability-related priorities. Alumex serves the Sri Lankan construction and building-products market while exporting to a range of countries in Europe, North America, Oceania, and Asia. Reference material identifies it as holding about 46 percent of Sri Lanka's aluminium market and as appearing in the LMD 100 ranking of Sri Lankan companies; the 2020/21 edition placed it at number 88. The company received a gold award at the 29th National Chamber of Exporters Awards in 2022. Its principal competitive proposition is a combination of local manufacturing scale, integrated finishing capability, certified production, customized architectural profiles, and increasing emphasis on export readiness and lower-carbon materials.
History
Alumex was incorporated in 1986 as a private company formed through a South Korean–Sri Lankan joint venture. Stanley William, identified as a founding director of Sampath Bank, served as the company's first chairman. Commercial operations began in 1988 at a facility equipped with a six-inch aluminium extruder and an anodizing plant. These initial capabilities established the foundation for an integrated profile-manufacturing business serving Sri Lanka's developing construction and building-products sectors. The company expanded its production infrastructure during the following decade. In 1999, it installed its first powder-coating plant, adding a coloured and protective surface-treatment capability to its extrusion and anodizing operations. In 2000, Alumex commissioned a seven-inch extrusion plant at Makola. The facility was described as the largest extrusion plant in Sri Lanka at the time. A modern anodizing plant was added in 2008, strengthening the company's ability to offer finished architectural profiles rather than only mill-finish extrusions. Control of the business shifted in 2006 when the Sri Lankan partners acquired the South Korean partner's stake. Hayleys PLC later acquired 95 percent of Alumex in 2010 for approximately LKR 2.2 billion. The transaction was strategically notable because Hayleys had historically concentrated much of its manufacturing activity on overseas markets, whereas Alumex was substantially oriented toward Sri Lankan domestic demand. The acquisition was funded through debt facilities, and Fitch Ratings placed Hayleys on negative rating watch in connection with the transaction. Alumex was re-registered as a public company under the name Alumex Limited in 2013. In March 2014, it announced an initial public offering of approximately LKR 839 million and became one of the Hayleys subsidiaries listed on the Colombo Stock Exchange. The listing gave the company access to public-market capital while maintaining its position within the Hayleys Group. Manufacturing modernization continued through the 2010s. In 2015, the company installed a horizontal fully automated powder-coating and wood-finish plant. In 2018, it launched an automated plant at Ekala, reportedly built at a cost of LKR 2 billion and designed for output of about 1,000 metric tonnes per month. Further investment was made at the Sapugaskanda facility, including reported spending of LKR 1 billion to increase capacity. Alumex also installed a second wood-finish plant in 2022. The company's business developed from domestic architectural supply toward a broader export proposition. In 2021 it commenced value-added manufacturing for export markets, with international destinations identified in the United Kingdom, United States, Canada, Australia, New Zealand, Germany, Italy, Singapore, and India. Its product portfolio includes extruded, anodized, powder-coated, and wood-finish aluminium profiles, including customized sections for construction and industrial uses. Sustainability and resource efficiency became more prominent in the company's public positioning. Alumex reports obtaining about 50 percent of its raw materials from recycled aluminium beverage cans. In 2022 it launched Ozon, described as Sri Lanka's first low-carbon aluminium brand and associated with environmentally friendly production technologies. The company has also presented an Elevate ESG roadmap. Its stated quality and sustainability framework includes ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications, together with Qualicoat, Qualanod, and Qualicoat Seaside accreditations. Alumex remains an active Hayleys Group company and a significant participant in Sri Lanka's aluminium market. Reference material attributes approximately 46 percent market share to Alumex and identifies related company Swisstek as holding a further share of the market. Alumex has appeared in the LMD 100 ranking of Sri Lankan companies and was ranked 88th in the 2020/21 edition. In 2022, it received a gold award at the National Chamber of Exporters Awards, reflecting its continuing emphasis on manufacturing and export performance.
