Huuao Fireproof 50mm 70mm 100mm 150mm PU Insulated Sandwich Wall Panels with Insulated PU Sandwich Wall Panel Price for Building

This product is a range of Polyurethane (PU) foam core metal sandwich panels of varying thicknesses, marketed for general building construction with an emphasis on their insulating and claimed fire-resistant properties.

1. "Fireproof" is a Major Red Flag: This is an inaccurate and potentially dangerous marketing term. Always ignore it and demand the official fire safety classification. For building materials, this is typically the EN 13501-1 standard (e.g., Class B-s1,d0, Class C, etc.). The actual fire performance of a PU panel can vary significantly based on its specific formulation.
2. PU vs. PIR Clarification: While called "PU," many modern panels use PIR chemistry, which offers superior fire resistance and thermal stability. A serious buyer must confirm the exact core material and its properties.
3. Thickness is Key: The offered range (50mm to 150mm) makes the product suitable for a wide array of applications, from simple warehouses (50-100mm) to cold storage and highly insulated buildings (100-150mm).
4. Application is Broad: These panels are designed for constructing the walls (and often roofs) of buildings like warehouses, factories, workshops, and agricultural buildings.
5. Missing Critical Specifications: The description is purely marketing and lacks the technical data required for a professional purchase:
   • Fire Rating Certificate (The single most important missing spec).
   • Lambda ( λ) Value (Exact thermal conductivity of the core).
   • Facing Details (Type of steel, coating, thickness, and profile).
   • Load-Bearing Capacity (spanning capabilities).

• Good heat resisting
• Steel plate:Well-known big brand(Baosteel;Lantian)
• Core material,glue:The manufacturer is a listed group with good quality
• Supply ability:40000㎡
• Scale of company: 800 employees,6 factories,1billion sale.

Widely used in Hospitals, laboratories, pharmaceutical factories, electronics factories, new energy, aerospace, food factories, beverage factories, cosmetics and other purification fields.

It can be used as wall panel and ceiling panel.When it's used as ceiling panel,it's not walkable.
