II. Performance & Advantages

• 1. Fire‑retardant and Compliant with Fire‑safety Codes

  Rolled from galvanized steel strip, it is non‑combustible by nature. When combined with fire‑proof panels, it forms fire‑resistant partition and ceiling systems to easily pass commercial fire‑safety inspections, outperforming traditional wood keels.

• 2. High Strength & Deformation‑Resistant

  As steel structural frames, it features great bending resistance and load‑bearing capacity. It will not swell, warp or crack under changing temperature and humidity. Ceilings resist sagging and partition walls stay stable.

• 3. Moisture & Corrosion Resistance for Long Service Life

  Galvanized base material provides rust‑proof and moisture‑proof performance. Suitable for basements, shops and humid coastal areas. It avoids mildew and insect infestation issues common with wood keels.

• 4. Light‑Weight to Reduce Building Load

  Much lighter than red‑brick and concrete partition walls, it lowers load pressure on main buildings, ideal for high‑rise buildings and office renovation projects.

• 5. Modular Assembly for High Construction Efficiency

  Standard‑size profiles allow on‑site cutting and assembly. Dry‑construction method requires no mortar plastering, shortening construction time and keeping job sites clean.

• 6. Flexible Processing for Diverse Shapes

  Compatible with various panels to build straight walls, curved partitions and decorative ceilings. The cavity facilitates concealed installation of water and electrical pipelines.

• 7. Excellent Acoustic Compatibility

  The cavity can be filled with sound‑insulation cotton and vibration‑damping accessories. Together with sound‑insulating panels and felts, it forms complete sound‑insulation wall systems, widely used in KTV and home‑theater acoustic projects.

• 8. Eco‑Friendly & Recyclable

  Metal base contains no adhesive with zero formaldehyde emission. Disassembled keels can be recycled for reuse.

III. Detailed Application Scenarios

Indoor Residential Scenarios

1. Household spaces: Framing for home‑theater partition walls & ceilings, indoor dividers and basement sound‑insulation walls, acting as the main framework of acoustic systems.

Commercial Entertainment Venues

2. Commercial KTV, chess rooms, escape rooms, recording studios and live‑stream studios: Partition and ceiling frames paired with various sound‑insulating & sound‑absorbing panels to meet both fire‑safety and acoustic acceptance requirements.

Office & Public Buildings

3. Office buildings, offices, meeting room dividers and ceiling bases; wall frames for libraries and exhibition halls to guarantee structural stability.

4. Educational facilities: Partition and ceiling frames for classrooms, piano rooms and lecture halls, complying with fire‑safety standards for campus commercial projects.

Industrial & Equipment Noise‑Reduction Scenarios

5. Frames for equipment rooms, fan‑pump rooms and quiet operating booths. Noise reduction and fire protection achieved with filling materials.

Cultural‑Tourism & Other Scenarios

6. Wall and ceiling base frames for hotel guest rooms, homestays, hospitals and exhibition halls, suitable for large‑scale commercial renovation projects.

Note: Light‑steel keels serve as structural frameworks for walls and ceilings. Sound‑insulation and fire‑proof performance can only be achieved by forming a complete system together with sound‑insulating panels, sound‑insulation cotton and fire‑retardant boards.
