A1 Fireproof Steel Structure Multi-layer Wall Panel
Steel-framed wall panels are suitable for use in factories, workshops, and modular buildings. Manufactured using a steel-composite process and paired with specialized fire-resistant core materials—available in rock wool or polyurethane foam—these panels feature a high-strength color-coated steel outer layer and a core material with a low thermal conductivity, delivering exceptional thermal insulation and energy-saving performance. The steel structure composite process involves multiple precision manufacturing steps, resulting in wall panels with a compact structure and high structural integrity, making them resistant to cracking and peeling. This ensures long-term, stable performance for buildings while balancing practicality, safety, and cost-effectiveness.
