Sungai buaya: Metal roofing and wall cladding solutions provider United Seasons Sdn Bhd (UniSon) today was officially recognised by Malaysia Book of Records for achieving the longest roofing sheet, measuring 166.49 metres installed at the YLL Supply Chain Hub in Sungai Buaya, here.
According to BERNAMA News Agency, the YLL Supply Chain Hub was designed to support high-volume logistics operations which require a roofing solution capable of long spans, durability, and operational efficiency.
UniSon General Manager (Projects) Zaidi Semail mentioned that the roofing sheets are produced as single and seamless units without any joints, designed to address technical challenges posed by Malaysia's weather such as increased rainfall intensity over the past decade. He emphasized that these single-piece roofing systems reduce the risk of leakage and simplify maintenance, particularly for buildings housing sensitive equipment like electronic manufacturing facilities.
Zaidi noted, "Today's certificate is for the longest roof in one piece. (Previously), people made long roofs but there were joints. So the Malaysia Book of Records company knew that our roof was produced in one piece, there were no joints." He added that the system is rarely used for large projects, which is why the certificate was awarded.
The record was achieved using the KAWA KZ400 Standing Seam Roofing System made from COLORBOND steel by NS BlueScope Malaysia, marking a significant milestone for Malaysia's construction industry and highlighting strong collaboration, technical expertise, and innovation in large-scale roofing solutions. Besides NS BlueScope Malaysia, the project involved a strong ecosystem of partners including Akitek Akiprima Sdn Bhd, CK Building Solutions Sdn Bhd, WBL Perunding Sdn Bhd, JQS International Sdn Bhd, and HL Roofing Sdn Bhd, working closely from design and planning through to execution.
UniSon supports various designs with a comprehensive range of metal roofing and wall cladding profiles, using materials such as COLORBOND, ZINCALUME, VERMOE, and PRIMAMAJU, catering to conventional applications and complex architectural requirements.
UniSon Managing Director P. Dhanabalan remarked that the achievement was also distinguished by the installation method, where the roofing sheets were roll-formed directly at roof level, enabling greater precision, efficiency, and installation quality while minimizing handling and the risk of damage. He noted, "This achievement by UniSon has been recognised by the Malaysia Book of Records, marking the success not only for our company, but also for Malaysia alongside our partners and customers in advancing roofing sheet development."
The Malaysia Book of Records recognition underscores the industry's growing capability to deliver complex, large-scale projects while reinforcing the importance of collaboration, quality workmanship, and trusted partnerships across the construction value chain.
