Rust Prevention Treatment Methods for GRC Curtain Wall and Steel Structure Connections? — A Guide to Anti-Corrosion Technology and Engineering Applications

The anti-rust treatment for connections between GRC curtain walls and steel structures directly affects durability and safety, and differentiated measures must be taken according to environmental conditions. Based on experience from coastal projects, Qinglong Group believes that high-quality rust prevention should be achieved through material selection, surface treatment, and electrical insulation, ensuring that connection points remain rust-free for 50 years.

Material selection is the foundation. 316 stainless steel or hot-dip galvanized steel is used, with a zinc layer thickness of ≥85μm. In Qinglong Group's projects, the anchor fittings passed 3000h salt spray tests without red rust. Surface treatment enhances corrosion resistance, using Dacromet coatings or epoxy resin sealing. Insulating gaskets prevent galvanic corrosion and extend service life.

Regular inspection and maintenance are essential. Annual inspections are recommended, with any issues addressed promptly. Through scientific corrosion prevention, Qinglong Group ensures safe and reliable connections.
