NERC has conducted systematic in-depth research and extensive experimental verification on building structures, material selection, and overall fire resistance performance to ensure full compliance with the requirements of the national “Code for Fire Protection Design of Buildings” (GB50016).

In structural design, a combination of multiple air layers and fireproof linings creates independent fire compartments within each unit, significantly enhancing overall fire resistance. Key components achieved a 1.5-hour fire rating through TUV PSB testing. In accordance with Clause 5.1.2 of GB50016, the fire resistance ratings for each component meet the following standards: steel columns (2.5 hours), steel beams (1.5 hours), floor slabs (1 hour), non-load-bearing exterior walls (1 hour), partition walls on both sides of evacuation corridors (1 hour), and room partition walls (0.5 hours). This comprehensive coverage addresses critical aspects of building fire safety, providing clients with reliable technical assurance.
