The cold storage panels are comprised of
an inner metal plate, an outer metal plate, and an intermediate layer of high-efficiency polyurethane insulation, ensuring exceptional thermal performance.
Horizontal and Vertical Operation Methods:
1. Utilize a waterproof film and SBS padding for superior protection.
2. Implement galvanized L or U-shaped positioning, securely fixed with expansion bolts.
3. Apply a robust sealant substrate for enhanced stability.
4. Install pre-sealed board seams, featuring double-sided groove sealant with a central polyurethane spray for optimal sealing.
5. Arrange the vertical wall panels with precision.
6. For structures exceeding 6 meters, ensure the installation of wall purlins, C-shaped steel, and quick mushroom nails for added support.
Suspended Ceiling Panel Operation Method:
1. Precisely determine the length and orientation of the ceiling panel based on the building's main beam, ensuring the panel joint is parallel for seamless integration.
2. Pre-install suspension beam structural components, including 6 # channel steel and fixture suspension beams, complemented by M12 lifting screws connected to a C-type steel keel.
3. Elevate the insulation top plate with care.
4. Fine-tune the lifting screw length for perfect alignment.
5. Apply polyurethane foam to the main joint; foam the PVC sleeve to interrupt the cold bridge, and trim the color steel folding piece for a polished finish.
