Three-dimensional grooved painted keel light steel anti-rust ceiling for shopping malls and factory buildings
Application scenarios
Our company's painted keel takes "high quality, strong adaptability and easy installation" as its core, and has formed differentiated advantages in terms of materials, craftsmanship and structural design. The material is made of high-purity light steel or aviation-grade aluminum alloy. The light steel version is galvanized, with a load-bearing capacity of up to 80kg/㎡, suitable for accessible ceilings. The aluminum alloy model has a natural anti-rust property and is especially suitable for damp or high-traffic scenarios such as kitchens, bathrooms, and shopping malls.
The process adopts an automated "three-coat and two-bake" procedure. The coating is made of environmentally friendly epoxy resin, with adhesion reaching grade 0 standard, scratch-resistant, anti-yellowing, and has passed the GB 18581-2021 environmental protection test, with no formaldehyde release. The structure is mainly T-shaped, covering two major series: flat and grooved, with multiple specifications such as 32-type and 38-type. It can precisely adapt to mainstream boards like 600×600mm gypsum board and mineral wool board, and is equipped with accessories such as hangers and corner strips. The installation efficiency is 30% higher than that of traditional keel.
The product also features strong weather resistance, remaining unchanged in shape in an environment ranging from -30℃ to 60℃, with a service life of over 15 years. It is widely applicable to commercial projects such as hospitals, schools, and office buildings, as well as home ceiling decoration scenarios, balancing practicality and aesthetics.
Differentiation advantage
div容器
| Comparison Dimension | Our Company's Products | Common Products of Other Companies |
| Basic Material | High-purity light steel/aerospace-grade aluminum alloy, with sufficient wall thickness (0.6-1.2mm), high rigidity and not easy to deform. | Ordinary steel/recycled materials, uneven wall thickness, light in hand and easy to bend with a little force. |
| Baking Enamel Process | Automated "three coats and two bakes" process, coating thickness over 50μm, strong adhesion, no paint peeling or yellowing after long-term use. | "Two coats and one bake" or thin coating, coating thickness less than 20μm, easy to have paint sagging and blistering, may fade within 1 year. |
| Rust Resistance & Durability | For light steel models: galvanized first then baked with enamel, salt spray test reaches 500 hours, usable in humid environments, service life over 15 years. | Simple galvanization or no galvanization, salt spray test less than 200 hours, easy to rust in humid places, needs replacement in 3-5 years. |
| Ease of Installation | Dimensional error ≤ 0.5mm/m, accurate snap-fit for main and secondary keels, complete set of accessories provided, 100㎡ ceiling can be installed in one day. | Large dimensional deviation (over 2mm/m), incomplete accessories, on-site cutting required, installation efficiency 40% lower. |
| Environmental Protection & Safety | Uses environmentally friendly epoxy resin coating, passes GB 18581-2021 test, no formaldehyde emission. | Mostly low-cost coatings, may contain formaldehyde and other harmful substances, pungent odor when smelled closely, fails environmental protection standards. |
Production Description
Our company's painted keel is widely applicable in various scenarios, covering the core demands of both commercial and residential decoration. In the field of industrial decoration, its T-shaped structure is often used in combination with mineral wool boards for the ceilings of office buildings and shopping malls. It is compatible with standard 600×600mm boards, ensuring efficient installation and a neat appearance. For hospital and school projects, it is recommended to give priority to its eco-friendly models, which do not release formaldehyde and meet fire safety standards. For damp areas, the aluminum alloy model can prevent rust and its durability meets the long-term usage requirements of public Spaces.
In home decoration scenarios, the moisture-proof and rust-proof version is used for kitchen and bathroom ceilings, paired with aluminum ceiling panels or waterproof gypsum boards, suitable for 300×600mm specifications. The living room and bedroom ceilings can be chosen in flat or recessed styles. The white coating can easily blend into various decoration styles. Moreover, the complete set of accessories is available, making self-installation or installation by professionals convenient. The balcony ceiling can also rely on its weather resistance to cope with temperature differences.
