Product Description

Differences in Fire Protection Grades

The core distinctions among Grade A, Grade B, and Grade C fireproof doors are rooted in three critical aspects: fire resistance time, application scenarios, and material composition. Grade A boasts an impressive fire resistance of ≥ 1.5 hours, making it ideal for high-risk zones. Grade B offers a substantial ≥ 1 hour of protection, suited for medium-risk environments. Meanwhile, Grade C provides ≥ 0.5 hours of safety, fitting for low-risk areas. Each grade is meticulously designed to meet specific fire protection requirements.
