2. Design of U-shaped glass

1,U-shaped glassThere are many ways to deal with the surface, common fine lines, transparent, color, etc. In addition to ordinary fine lines, the other models need to be marked during design.

2, U-shaped glass is a non-combustible material, we can achieve a very good fire rating, if there are special requirements, design and label according to relevant specifications.

3 For the installation method of U-shaped glass, please refer to the installation combination method. It is commonly used that the double-row wings are arranged in pairs in the hollow at the seam, or the single-row wings are installed inward or outward.

4 The U-shaped glass used for the external wall, the installation length depends on the local wind load, the height of the glass from the ground, etc.
