1. Product Overview
────────────────────────────────────────────────────
Insulated Metal Panels (IMPs), also known as Sandwich Panels, are the premier choice for the building envelope of modern steel structures. They consist of a rigid insulation core sandwiched between two facings of coated steel.
As a “All-in-One” solution, IMPs provide superior thermal insulation, water resistance, and architectural finish in a single component. Compared to traditional multi-layer wall systems, our factory-prefabricated panels enable 50% faster installation, reducing construction timelines while delivering a sleek, modern aesthetic.
2. Key Advantages
────────────────────────────────────────────────────
- High Thermal Efficiency: Featuring high R-values (especially PU/PIR cores), our panels eliminate thermal bridging, significantly reducing heating and cooling costs for your facility.
- Rapid Installation: The modular tongue-and-groove interlocking system allows for quick assembly. One panel acts as the structure, insulation, and exterior finish.
- Architectural Flexibility: Available in various profiles (Flat, Micro-rib, Embossed) and connection types (Concealed or Exposed fasteners) to meet your aesthetic vision.
- Fire Resistance: Rockwool core panels achieve Class A non-combustible rating, meeting strict international fire codes.
- Durability: Coated with premium paints like PVDF or HDP, the steel skins resist corrosion and fading, ensuring a lifespan of 20+ years.
3. Core Material Selection Guide
────────────────────────────────────────────────────
- PU / PIR (Polyurethane): The best for thermal insulation. Ideal for cold storage and controlled environments.
- Rockwool: The best for Fire Safety (Non-combustible). Essential for hazardous industrial workshops and public buildings.
- Glass Wool: Good sound absorption and cost-effective.
- EPS (Polystyrene): Lightweight and budget-friendly for general applications.
4. Applications
────────────────────────────────────────────────────
- Industrial: Warehouses, manufacturing plants, distribution centers.
- Cold Storage: Refrigerated warehouses, food processing facilities (PU core recommended).
- Commercial: Office buildings, showrooms, shopping malls.
- Clean Rooms: Pharmaceutical and electronics manufacturing.
5. Installation Guide
────────────────────────────────────────────────────
- Orientation: Panels can be installed vertically or horizontally. Horizontal installation requires specific flashing details for a modern strip look.
- Connection: Panels interlock via a male-female (Tongue & Groove) joint.
- Fastening:
- Hidden Joint: Screws are driven through the joint tongue and covered by the next panel.
- Visible Joint: Screws penetrate through the panel face into the sub-structure (girts).
- Sealing: Butyl tape and silicone sealants are applied at joints and trims to ensure a weathertight seal.
6. Maintenance
────────────────────────────────────────────────────
- Cleaning: Annual washing with mild detergent and low-pressure water keeps the coating fresh.
- Inspection: Check sealants at base flashings, corners, and window openings regularly.
- Touch-up: Repair any deep scratches immediately with matching touch-up paint to prevent corrosion.
7. Packaging & Shipping
────────────────────────────────────────────────────
- Protection: Each panel is covered with a PVC protective film (peel off after installation).
- Bundling: Stacked flat on EPS foam blocks and wrapped in plastic film to prevent moisture damage during sea transit.
- Loading: Loaded into 20GP or 40HQ containers. We utilize optimized stacking plans to reduce freight costs.
