Building Anchor Bolt/ Fastener Testing

Building anchors and fasteners are critical connecting components in the construction field, essential for structural stability and construction safety. The market size has shown steady growth, exceeding RMB 10 billion in 2019. With the development of the construction industry and the release of demand for old building renovation, the market is expected to reach RMB 20 billion by 2025. The product range is rich. By material, they can be metal, plastic, composite, etc., suitable for different scenarios. By structure, there are expansion type, undercut type, chemical (adhesive) type, etc., meeting diverse connection needs. Application scenarios are extensive, covering building structural connections, interior and exterior decoration fixing, and various equipment installations, making them indispensable basic components in construction engineering.
