Hailong Prefab

Shenzhen Hailong (深圳市海龙绿建科技有限公司, also presented in English as Hailong Prefab) is a Chinese building-products manufacturer specializing in prefabricated steel structures, metal roofing and building envelope systems. According to its official website, the company was established on 3 November 2004 as 深圳市海龙钢结构材料有限公司, with registered capital of RMB 10 million and a factory area of 25,000 square metres at 305 Xinsheng Road, Longgang District, Shenzhen. It describes itself as one of the larger steel-structure enterprises in South China, operating two production bases — Shenzhen Longgang and Foshan Sanshui — with an annual capacity of 100,000 tonnes of steel structures and 6 million square metres of panels and profiles, and close to 150 employees. The company's product range is organized into several series: aluminium-magnesium-manganese (Al-Mg-Mn) roofing, profiled steel sheets, metal envelope systems, purlins, and steel bar truss decking, together spanning hundreds of product varieties. Its website showcases roof systems (HL75, Al-Mg-Mn roof, 788-type, HL38 flexible waterproof roof, HL30-287-860, 伯爵板, HL58-311, HL38-315, HL35-130-780, HL22-350), wall systems, floor decking (open and closed decking, steel bar truss decking), accessory systems (edge flashing, downpipe systems, purlins) and BIPV photovoltaic systems. The company positions itself as a one-stop supplier with a standing inventory of about 3,000 tonnes, a 98% sampling inspection rate, ISO9001 quality certification, and 24-hour after-sales service. Hailong's customer base and partnerships include major Chinese construction and steel groups such as China Railway, China State Construction, Huaxi, Baosteel and Yieh Phui, and it states it holds a Grade-1 qualification as a steel-structure specialist contractor and is a council member of the Guangdong Provincial Steel Structure Association. Its stated goal is to build leading advantages in building steel structures and become a large-scale, quality-focused Chinese steel-structure manufacturer. The group has expanded through affiliated entities: Foshan Hailong Green Building Technology (佛山市海龙绿建科技, established 2018 in Sanshui Leping Industrial Park, 15,000 square metres, 30,000 tonnes steel and 3 million square metres panels capacity) and Shenzhen Hailong New Energy Engineering Technology (深圳海龙新能源工程科技有限公司, founded 2021, based in Vanke Building, Longgang, Shenzhen), which focuses on building-integrated photovoltaics (BIPV), EPC construction and investment/operation of industrial rooftop solar. The company describes itself as an "internet + smart energy" new-energy building enterprise and says its basic manufacturing system has focused on building manufacturing for eighteen years.

Shenzhen Hailong traces its origins to 深圳市海龙钢结构材料有限公司, established on 3 November 2004 with registered capital of RMB 10 million. In 2005 the company put its Shenzhen steel-structure facility into operation on a site of about 20,000 square metres. For its first decade the business focused on steel-structure materials and metal building products for the South China construction market. A significant turning point came in 2016, when the company introduced an aluminium-magnesium-manganese (Al-Mg-Mn) metal roofing production line and formally entered the Al-Mg-Mn roofing market. This expanded its offering from basic steel structures and profiled sheets into higher-value architectural metal roofing and envelope systems. In 2018 the group extended its manufacturing footprint with the establishment of 佛山市海龙钢结构材料有限公司 (Foshan Hailong Steel Structure Materials Co., Ltd.) in the Sanshui Leping Industrial Park, Foshan, covering 15,000 square metres. The Foshan base added capacity for steel structures and panels, complementing the Shenzhen Longgang base. Together the two bases gave the company an annual capacity described as 100,000 tonnes of steel structures and 6 million square metres of panels and profiles, with close to 150 employees. In 2021 the group moved into new energy with the founding of 深圳海龙新能源工程科技有限公司 (Shenzhen Hailong New Energy Engineering Technology Co., Ltd.), based in Vanke Building, Longgang, Shenzhen. This entity focuses on building-integrated photovoltaics (BIPV) for industrial buildings, EPC construction, and investment and operation of solar installations. The company presents itself as an "internet + smart energy" new-energy building enterprise, developing lightweight, high-efficiency BIPV technologies, and states that its basic manufacturing system has focused on building manufacturing for eighteen years. Over its history the company has built a product portfolio spanning Al-Mg-Mn roofing, profiled steel sheets, metal envelope systems, purlins, and steel bar truss decking — hundreds of varieties in total — and has positioned itself as an integrated producer, seller and developer. It reports partnerships with major construction and steel groups including China Railway, China State Construction, Huaxi, Baosteel and Yieh Phui, holds a Grade-1 steel-structure specialist contractor qualification, and is a council member of the Guangdong Provincial Steel Structure Association. Its stated goal is to build leading advantages in building steel structures and become a large-scale, quality-focused Chinese steel-structure manufacturer.
