Sealing Treatment Methods for GRC Panel and Metal Component Connections — Anti-Seepage and Anti-Rust Technology for Durability Assurance

Sealing treatment for the connection between GRC panels and metal components is key to preventing water seepage and corrosion, and must be addressed through material selection, structural design, and construction control systems. Qinglong Group recommends a combination of silicone sealant (movement capability ≥25%), backing rods, and waterproof gaskets, achieving a seal service life of ≥20 years. Through multiple layers of protection, the long-term reliability of connection points is ensured.

The sealing materials offer excellent weather resistance; after curing, the silicone sealant has a Shore A hardness of 20-30, accommodating deformation caused by temperature differences. In Qinglong Group's coastal projects, the sealing systems underwent 3,000 hours of aging without failure. The structural design incorporates drainage cavities to avoid water accumulation. Construction controls the sealant joint width (8-15mm), ensuring fullness and continuity. These treatments safeguard connection safety.
