Anti-Rust Measures and Application Points for Top-Burst Screws in GRC Component Installation

The durability of architectural decoration begins with rigorous handling of every detail, and the anti-rust treatment of expansion anchor screws in GRC component installation is precisely the key factor determining overall project quality. As an industry leader with 28 years of dedicated expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group leverages full-chain technical strength to provide designers and owners with expert-level solutions from material selection to installation and maintenance, ensuring that every architectural detail stands the test of time.

Corrosion Risks of Expansion Anchor Screws in GRC Component Installation and Industry Pain Points

In GRC component installation projects, expansion anchor screws serve as the core load-bearing components connecting walls to components, and their anti-rust treatment directly affects the safety and durability of architectural decoration. In traditional installation, issues such as screw corrosion and component loosening caused by inadequate anti-rust treatment not only compromise the building's appearance but may also pose safety hazards. Especially in complex environments such as high humidity and heavy salt spray, metal connectors without professional anti-rust treatment are highly prone to electrochemical corrosion, shortening the service life of GRC components. Drawing on practical experience from thousands of projects across the country, Qinglong Group has developed deep insight into this industry pain point and established a systematic anti-rust solution framework.

Core Technologies and Implementation Points of Anti-Rust Treatment for Expansion Anchor Screws

The Qinglong GRC component installation team adopts a triple-barrier anti-rust process, achieving full-process quality control from material selection to construction techniques. First, at the screw selection stage, preference is given to components with composite anti-rust treatment of hot-dip galvanizing plus Dacromet coating, achieving over 5,000 hours in salt spray tests—an anti-rust capability three times that of ordinary galvanized parts. Second, at the installation stage, an innovative dual-protection sealant technology is introduced, combining pre-applied anti-rust grease on threads with silicone sealing after installation to form a physical isolation barrier. Finally, Qinglong's signature on-site anti-corrosion coating repair process provides immediate anti-rust treatment for machined areas such as cut or drilled sections, ensuring no corrosion blind spots. This process system has been successfully applied in landmark projects such as the Dongguan Women and Children's Activity Center and the Century Plaza on Nanjing East Road, maintaining intact performance after years of exposure to the elements.

Implementing Anti-Rust Craftsmanship with Qinglong's Full-Chain Service Guarantee

As a national-level high-tech enterprise integrating detailed design, manufacturing, construction and installation, and after-sales maintenance, Qinglong Group incorporates anti-rust craftsmanship into the full lifecycle management of GRC components. At the detailed design stage, engineers customize anti-rust plans based on the climate parameters of the project location (such as humidity and salt content); the production stage employs automated spraying equipment to ensure coating uniformity; the construction process is supported by a professional quality inspection team for torque testing and anti-rust process acceptance; and the after-sales stage achieves early detection and early resolution of corrosion risks through regular inspections and intelligent monitoring systems. This full-chain service model has enabled Qinglong GRC components to deliver durability far exceeding industry standards in strategic cooperation projects with property groups such as Poly and China Overseas.

From technology R&D to engineering practice, Qinglong Group has always upheld the principle of "meticulous rigor and constant pursuit of excellence," perfecting details such as anti-rust craftsmanship to the highest degree. As Vice Chairman Unit of the China GRC Association and a participant in formulating industry standards, Qinglong not only provides customers with high-quality UHPC/GRC/GRG/GRP products but also empowers the perfect unity of architectural aesthetics and structural safety through professional solutions. Choosing Qinglong means choosing the technical confidence built on 28 years of industry experience and a lasting commitment to building quality.
