Light Steel Keel Selection Tips: Essential Insights for Optimal Construction

Maximize your construction's potential with our comprehensive guide to selecting high-quality light steel keels. Learn about key factors, such as strength, corrosion resistance, and design compatibility, to ensure your project stands the test of time. Get the inside scoop on finding the perfect solution for your building needs.

1. Choose the cross-sectional shape: When selecting light steel keels, first choose the corresponding shape based on your own purpose. Light steel keels come in several cross-sectional forms such as U-shaped, C-shaped, T-shaped, and L-shaped. U-shaped and C-shaped keels are both load-bearing and can be used as partition keels. U-shaped keels serve as main supports, while C-shaped keels are used as cross-bridging keels for clamping. T-shaped and L-shaped keels are generally used for non-load-bearing ceilings; T-shaped keels are for main and cross-bridging keels, and L-shaped keels are for edge keels.

2. Select the thickness of light steel keels: Light steel keels should not be chosen with a thickness lower than 0.6mm. When purchasing, you can check the product specifications for information such as length and thickness. You can also judge the thickness of the aluminum panel by eye and touch.

3. Check the galvanizing process of light steel keels: To prevent rusting, both sides of the light steel keel should be galvanized. When choosing, select those with a galvanized layer that is free of peeling and pitting. Only such qualified products can ensure moisture resistance.

4. Observe the "snowflakes" on the light steel keel: High-quality light steel keels have a snowflake-like surface after galvanizing. When purchasing ceiling materials, pay attention to whether the keel has a snowflake-like galvanized surface. If the snowflake pattern is clear, the touch is relatively hard, and the gaps are small, it belongs to a keel of good quality.

5. Choose the thickness of light steel keels: Generally, it should not be lower than 0.6mm.

6. Ensure that light steel keels have an advanced precision processing system: Because a precision processing system can help with: good product flatness and straightness, low internal stress, and ensure no stress deformation.

7. Require excellent corrosion resistance: The product should use high-quality continuous hot-dip galvanized sheets as raw materials, with strong zinc layer adhesion, and the double-sided galvanized quantity reaching or exceeding the national standard for first-class products.

8. The product has high-standard cross-sectional dimensions, meeting national related standards: High-standard cross-sectional dimensions, with flange heights higher than the national standard, greater moment of inertia, enhanced structural stability, and ease of construction. For example, the national standard stipulates that the flange height of partition wall U-shaped keels should be greater than 35 millimeters, while most keel manufacturers' products are less than 35 millimeters, and the flange height of U-shaped keels reaches 40 millimeters.
