What materials are used for ductwork panels?
Source:
Metal sheets: galvanized steel sheet (most commonly used), ordinary thin steel sheet, stainless steel sheet, aluminum and aluminum alloy sheet, and plastic‑composite steel sheet (such as PVC‑laminated steel sheet).
Non-metallic panels: rigid polyvinyl chloride (PVC) sheets, fiberglass-reinforced plastic (FRP) sheets, and inorganic glass–magnesium composite panels.
Composite panels: color‑steel sandwich panels (e.g., with polyurethane or rock wool cores), and aluminum‑foil composite insulation panels (commonly used in flexible ductwork or thermal insulation systems).

Characteristics and Applications of Glass-Magnesium Purification Panels
Outstanding fire performance: The core material is Class A1 non-combustible (GB 8624-2012), remaining non‑combustible and producing no toxic smoke when exposed to fire, making it suitable for high‑fire‑safety areas such as operating rooms, P2/P3 laboratories, and electronic manufacturing facilities.

What are the advantages of steel fire door core panels?
Robust construction and excellent impact resistance: Cold-rolled steel door frames (≥1.2–1.5 mm) and door leaves (0.8–1.2 mm) deliver exceptional mechanical strength, resisting deformation and external forces, making them ideal for high‑frequency use or high‑risk environments such as industrial facilities, stairwells, and utility shafts.

What are the main functions of fireproof panels?
Fire‑retardant and flame‑resistant: Complies with Class B1 (decorative HPL) or Class A1 (inorganic fire‑proof board) non‑combustible/low‑flammability standards; does not promote combustion when exposed to fire and emits low smoke and toxicity. When used for partition walls, suspended ceilings, countertops, and other applications, it can effectively inhibit the spread of flames.
