The self-cutting bolt of suspended ceiling is a special connecting piece which can realize high efficiency and stable fastening in suspended ceiling engineering, and provides a reliable solution for the safe construction of suspended ceiling structure. Core advantages of materials and technology: high-quality metal materials and galvanized treatment, with good anti-rust performance and mechanical strength, in the ceiling construction environment to maintain a long-term tightening effect. Self-cutting fastening design: The unique self-cutting thread structure can cut and bite the base material independently during installation, which can realize fast and stable connection and greatly improve the ceiling construction efficiency. Connection reliability: After connection, it can bear large tensile force and shear force, effectively prevent the ceiling components from loosening and falling off, and ensure the overall stability and use safety of the ceiling structure. Application Scenario: Widely used in ceiling construction of various buildings, it is a key component to realize fast and stable fixation of ceiling keel, decorative panel and other components, which helps the ceiling project to be advanced efficiently and safely.
