The core advantages of this U-shaped ceiling light steel keel lie in its material and structural design. First, it uses 0.6mm thick hot-dip galvanized cold-formed steel sheet with G90 galvanizing grade, ensuring a galvanized layer thickness of about 85μm, which provides excellent anti-rust and anti-corrosion performance, even in slightly humid environments. The U-shaped cross-section with 50mm web height and 15mm flange width maximizes the structural stability and load-bearing capacity of the keel, reaching 80kg per linear meter, which can meet the load requirements of most conventional ceiling lamps and auxiliary facilities. In addition, the surface treatment adopts standard hot-dip galvanizing, which eliminates the need for secondary painting during construction, saving construction time and cost. Compared with traditional wooden keels, this product has a longer service life, lower maintenance cost, and meets the fire protection requirements of modern construction, making it a high-quality choice for ceiling engineering.
This product has complete technical parameters: the thickness of the steel plate is 0.6mm, the cross-section is standard U-shaped, the web height is 50mm, the flange width is 15mm, and the standard length is 3000mm. The galvanizing grade is G90, and the surface treatment is pure hot-dip galvanizing, which complies with the ASTM C645-19 standard. The load-bearing capacity per linear meter is 80kg, which can meet the support needs of most conventional ceiling systems. Each box is packed with 20 pieces, which is convenient for transportation and storage. The dimensional error of the product is controlled within ±0.5mm, ensuring that it can be perfectly matched with standard ceiling accessories during construction, reducing the problem of uneven installation gaps caused by dimensional errors.
This general-purpose U-shaped ceiling light steel keel is suitable for a variety of light ceiling scenarios, including residential living rooms, bedrooms, study rooms and other home decoration ceiling projects, small commercial shops, boutique stores and other local ceiling decoration, as well as office areas, meeting rooms and other public space ceiling matching. It can be used with light steel keel ceiling systems, and is suitable for construction scenarios with requirements for fire protection, moisture resistance and structural stability. Compared with wooden keels, it has better weather resistance and longer service life, and can meet the current market's demand for green and environmentally friendly building materials.
