Light steel keel: Galvanized anti-rust, stable structure, setting a new benchmark for building decoration support systems
Application scenarios
Our company's light steel keel, with its core advantages of high strength, rust and corrosion resistance, and easy installation, is widely applicable to various building scenarios. In residential decoration, it can be used for the ceilings of living rooms and bedrooms as well as interior partition walls. It is environmentally friendly, free of formaldehyde, earthquake-resistant and stable, and meets the needs of modern home decoration. Commercial buildings such as office buildings, shopping malls and hotels, with their efficient installation features, shorten the decoration period. The optimized cross-sectional design meets the load-bearing requirements of large-area ceilings, facilitating the rapid implementation of commercial Spaces. Public facilities such as schools, hospitals and subways meet fire and earthquake resistance standards and are corrosion-resistant, conforming to public safety standards and reducing maintenance costs in the later stage. In industrial buildings such as industrial plants and warehouses, it can adapt to complex environments like humidity and high temperature, providing reliable support for workshop partitions and equipment brackets. In old house renovation and refurbishment projects, there is no need for large-scale demolition and modification. The snap-on installation can quickly refresh the base structure and solve the pain points of base support in different building scenarios in one stop.
Differentiation advantage
| Advantage Dimension | Our Company's Light Steel Keels | Competitors' Products |
| Raw Material Quality | Adopt Q235 high-grade cold-rolled steel strip with yield strength ≥305MPa, zero formaldehyde added, complying with EU RoHS environmental standards | Mostly use ordinary cold-rolled plates with low yield strength, some containing formaldehyde and heavy metal impurities |
| Rust Resistance | Hot-dip galvanizing process, zinc coating thickness ≥120g/㎡, adhesion grade 1, service life over 20 years in humid/coastal environments | Conventional galvanizing or painting treatment, zinc coating thickness 80-100g/㎡, prone to peeling and rusting, service life 8-12 years |
| Structural Strength | Optimized cross-sectional mechanical design + reinforcing rib structure, main keel bearing capacity 80kg/m, seismic resistance up to grade 8, no deformation at -30℃~80℃ | No reinforcing structure, bearing capacity ≤60kg/m, low seismic grade, easy to bend and sag in temperature difference environments |
| Process Precision | Fully automatic rolling production line, cross-sectional dimension tolerance ≤±0.3mm, cut edges with rounded chamfers, no burrs | Semi-automatic production, tolerance over ±1mm, sharp cut edges, easy to scratch accessories and constructors |
| Installation Adaptability | Snap-on quick-install design, compatible with mainstream finishes such as gypsum board/mineral wool board, 1 person can install 50㎡ per day, efficiency increased by 30% | Require welding/bolt fixing, single adaptability, complex construction, high labor cost |
Production Description
Our company's light steel keel adheres to the production philosophy of "craftsmanship as the core and quality as the soul", strictly controlling every detail from the source. Selected Q235 high-grade cold-rolled steel strips are used as raw materials. Strict composition testing is carried out to ensure that the tensile strength and toughness meet the standards, fundamentally guaranteeing the stability of the structure.
Adopting a fully automatic high-precision rolling production line and through a multi-pass continuous forming process, the cross-sectional dimensions of the keel are precisely controlled, with a tolerance of ≤±0.3mm, ensuring a tight and seamless installation and splicing. The key process is equipped with hot-dip galvanizing technology, with a uniform zinc layer thickness of ≥85μm, strong adhesion, effectively resisting oxidation and rust, and extending the service life.
The production process incorporates online straightening technology to ensure the straightness of the keel and prevent installation deformation. Each batch of products has undergone multiple tests such as compressive strength, flexural strength and rust prevention, and complies with the national standard GB/T 11981-2021. The fully automated production process reduces manual intervention, balancing efficiency and consistency, ensuring that each light steel keel serves as a reliable support for the building's base layer.
