Color steel plates are extremely common in the construction industry. How to choose color steel plates?
1. Observe the exposed edge of the color steel plate
When we buy color steel plates, we must check whether the exposed cross-section of the color steel plate is fine in crystals. If it is dark, dark and its existence in magazines and periodicals, it indicates that the quality is weak. If the cross-section crystals are fine, it indicates that the quality is excellent. .
2. Observe the thickness of the substrate and the thickness of the coating
The color steel plate is produced by the bottom thick steel plate and the colorful posterior layer of the peritoneum, so we need to pay special attention to the thickness of the base material and the thickness of the coating when purchasing. The thickness of the rear layer is below 0.15mm.
3. Listen to the sound
When purchasing color steel plates, we can also tap the color steel plates with fingers or hard objects, and listen to the sound sent. Usually, the sound effects of color steel plates with excellent materials are very bright and crisp.
