304 Stainless Steel Connector Seismic Test for Prefabricated Buildings

1. Introduction: Seismic Safety Demands of Prefabricated Buildings

Prefabricated building construction grows rapidly in modern architecture.

All structural components are factory-produced and on-site assembled.

Connectors are the key load-bearing and linking parts of the whole frame.

Traditional carbon steel connectors face rust and aging risks.

304 stainless steel connectors feature corrosion resistance and high toughness.

Seismic performance tests verify their safety in earthquake-prone areas.

Test data supports standardized application of building connectors.
