65 Years of Water Revolution

When the Nation chose to be content with GI pipes for their water needs, we were compelled in our spirit to stand out and so was the water revolution born in the year 1957 with the first Thermoplastic technology. S-lon Lanka (Pvt) Ltd, a subsidiary of the Capital maharaja Group which pioneered Thermoplastic pipes in Sri Lanka operated directly under the financial support of the parent company under the industrial division since 1957, ventured into independent operations in 1987.

Brand ‘S-lon’ had its origins in Japan by a company named Shikushi which was rejuvenated in 1957 by TCMOL. Having successfully introduced PVC to the market, in-house production commenced in 1958 through its factory which was situated in Ratmalana, with the need to upgrade technology and to meet the ever increasing demand, the factory was shifted to a 10 acre land in Singakkuliya, Pannala. Today, S-lon plays a pivotal role in the development of the nation at large. Being part of a country rooted with a captivating heritage and warm Sri Lankan hospitality, S-lon has touched the lives of Sri Lankans throughout the island for over six decades.

S-lon had been a part of some of our Nation’s most significant and prestigious construction projects to date. Amongst many successful projects in its 65 year journey, S-lon continued to be the preferred choice amongst some of the latest projects that caught fame. Colombo Racecourse, Independence Arcade, On Three 20 apartment complex, The Sands, Waskaduwa, Chaaya Bey, Hikkaduwa, the Defense Headquarters at Akuregoda, and the newly rehabilitated Jaffna Railway Station.

Today, S-lon manufactures and distributes a diverse portfolio of water management solutions that include a comprehensive range of pipes and fittings, rain water disposable systems, sewage pipes & fittings, hot water piping system, ball valves, ABS taps and water pumps. We have taken our expertise and gone a step further to provide solvent cement, garden mesh, chrome plated faucets & accessories and roofing sheets.
