Product Description

The cold storage panels are consisted by

an inner metal plate, an outer metal plate, and an intermediate polyurethane insulation layer.
Horizontal and Vertical Operation Methods:
1. Employing a robust waterproof film coupled with reliable SBS padding.
2. Secure with precision using galvanized L or U-shaped positioning fixed firmly with expansion bolts.
3. Substrate sealing with superior sealants.
4. Pre-installation of board seam sealant, featuring a double-sided groove sealant complemented by a polyurethane spray in the middle.
5. Erecting a steadfast vertical wall panel.
6. For lengths over 6 meters, ensure the integration of wall purlins, sturdy C-shaped steel, and quick-install mushroom nails for enhanced stability.

Suspended Ceiling Panel Operation Method:
1. Strategically determine the length and lifting direction of the ceiling panel, aligning with the building’s main beam. Ensure panel joints run parallel to the main beam for optimal support.
2. Pre-install suspension beam structural components, utilizing 6 # channel steel and fixtures for secure suspension of beams and M12 lifting screws, connected to a robust C-type Steel keel.
3. Elevate the insulation top plate with precision.
4. Fine-tune the length of the lifting screw for perfect alignment.
5. Professionally apply polyurethane foam to the main joint, equip the PVC sleeve with foam to thwart cold bridges, and neatly trim with color steel folding pieces.
