The core highlight of this product is the dual C-shaped cross-sectional structural design, which improves the bending strength and load-bearing performance by superimposed C-shaped keels, improving the load-bearing performance by 60% compared with conventional single C-shaped keels. Q355 high-strength steel ensures that the keel . The standard 4m length reduces the need for on-site splicing and improves construction efficiency. The hot dip galvanized surface treatment can resist humidity and corrosive gases in the office environment, extending the service life of the product. Pre-installed heavy-duty connector interfaces adapt to the installation needs of large-scale partitions, and can be used as the main keel of office partitions to support higher partition heights and heavier panel weights.
Manufactured from Q355 high-strength cold-formed steel, this keel has a thickness of 1.0mm and a standard length of 4000mm (13.1ft). It features a double C-shaped composite cross-section with a flange width of 35mm and a web height of 100mm. The surface is treated with hot dip galvanizing, complying with GB/T 11981-2008 and EN 13964 European light steel keel standards. It weighs 1.68kg per meter and has a single-piece load-bearing capacity of up to 2200N/m. The connector interface uses standardized bolt holes, compatible with heavy-duty partition connectors. The dimensional tolerance is controlled within ±0.2mm, ensuring the verticality and stability of the installed partition, and can support a maximum partition height of 6 meters.
It is mainly applicable to the load-bearing partition construction of office buildings, commercial complexes and large exhibition halls, compatible with heavy partition panels such as high-density gypsum board, fiber cement board and metal panels. It can be used as the main keel of office partitions, supporting a maximum partition height of 6 meters, meeting the regional division needs of large office spaces. It can also be used for non-load-bearing partition construction of industrial workshops, and is one of the core support materials for large commercial space decoration. It meets domestic Chinese and European construction standards, adapting to foreign trade and domestic large-scale construction projects.
