Zinc chromium alloy plate, using high-strength alloy substrate, integrates strength, aesthetics and sealing. The panel, reinforcement bars, and corner brackets are tightly connected through scientific structural design to form a highly rigid whole, ensuring long-term flatness and seismic resistance. Sharp and sharp R-corners are shaped into sharp lines, and the corners are welded free with edge sealing and glue injection technology to eliminate water leakage hazards. Empowering building facades with higher performance and superior performance through precision structure, excellent strength, and craftsmanship.
