High-Speed Industrial Garage Sliding Doors Lift Up Roller Shutter Insulation Door

For our heavy lift door, the door sheet is made of prepainted steel sandwich panel, PU sandwich panel with 1m height, and the doorframe is made of sealing door trim. It has better anti-wind performance, and sealing heat retaining properties than a normal lift door. This kind of door is suitable to be used as the big gate of a wide-span warehouse and workshop.

• Door Sheet: Made of prepainted steel sandwich panel. This type of panel typically consists of two steel sheets bonded to a core material, often polyurethane (PU) foam, creating a durable and insulating structure. The prepainted steel adds an additional layer of protection against corrosion and enhances aesthetics.
• PU Sandwich Panel: PU sandwich panels are known for their excellent thermal insulation properties. They provide insulation against heat transfer, helping to maintain consistent temperatures inside the building while also potentially reducing energy costs for heating or cooling.
• 1m Height: The height of the PU sandwich panel suggests that it’s designed for heavy-duty applications, providing structural integrity and stability for larger door openings.
• Doorframe: Made of sealing door trim. The doorframe is crucial for providing structural support and ensuring proper sealing when the door is closed. Sealing door trim indicates that it’s designed to provide a tight seal when the door is closed, enhancing the door’s weather resistance and preventing air infiltration.
• Anti-wind Performance: This indicates that the door is designed to withstand high wind loads, which is important for maintaining structural integrity and safety, especially in areas prone to strong winds or storms.
• Sealing Heat Retaining Property: The sealing properties of the door, along with the insulation provided by the PU sandwich panel, help retain heat inside the building, improving energy efficiency and creating a more comfortable working environment, particularly in colder climates.

Overall, this type of heavy lift door is well-suited for industrial applications where durability, insulation, weather resistance, and structural integrity are essential requirements. It’s particularly suitable for wide-span warehouses and workshops where large openings need to be securely sealed while providing thermal insulation and weather protection.
