Sturdy Fire Rated Curtain Wall System Shockproof Exposed Frame Curtain Wall Glass System

This curtain wall system exhibits stable performance. The framework employs a boss structure, allowing the glass to directly bear the load on the bosses. This design eliminates the need for glass support brackets within the system, reducing the number of components. Additionally, the unique dovetail-shaped embedded sealant groove ensures that the sealing strips are securely locked in place, significantly minimizing the risk of detachment. This innovative approach lowers construction complexity and enhances the overall stability of the system.
