The B1 Fireproof Sandwich Panel segmentation by application reveals five primary end‑use categories that together constitute the total market volume. Industrial warehouses dominate with an estimated 35 % share, driven by large façade areas, stringent fire‑code compliance, and the need for rapid construction. Commercial buildings such as office towers and retail malls account for roughly 30 % of demand, reflecting the premium placed on fire‑resistant cladding in high‑occupancy environments. Infrastructure projects—including bridges, tunnels, and utility enclosures—represent about 20 % of the market, where the B1 rating satisfies public‑safety regulations for critical assets. Residential complexes contribute near 10 %, as developers adopt fire‑proof panels to meet evolving building codes for multi‑family housing. Finally, transportation facilities (railway stations, airports, and bus terminals) hold a modest 5 % share, limited by niche architectural requirements. These percentages are illustrated in the accompanying pie‑chart, underscoring each segment’s quantitative impact on overall market size.
