Aluminum Checker Plate PU panel

Aluminum Checker Plate PU panel

Cold Storage Panel is fit for the projects which have serious require of keeping warm. Cold Storage Panel are made by upper and lower layers pre-painted galvanized steel sheets or stainless steel, to the middle infused polyurethane foam, through the heating, pressure, and the formation of foam sandwich panels. The metal top layer can be a colored stencil plate, the surface is smooth and the whole performance is excellent.
Cold Storage Panel is universally acknowledged the best material of heat insulation and heat preservation nowadays and it can perform a good anticorrosion, antirust and anti-weathering.

Cold Room Pu Panel Details: 

1. Our Pu Panel Standard width is 960mm , the length can be customized according to your requirements .
2. PU panel is B2 fire proof grade, safe situation.
3.  cam lock connection pu panel , very easy to install, anti-corrosion effect is very good.
4. 40-42 kg/m3 density PU foam, the insulation effect is good . In other words , can save your electricity cost .
5. CFC-free raw material , environmental friendly.
After placing order ,our designer will design an exact drawing for your cold room , you can install it easily .

Features and advantages:
1.Convex structure: Panels are joined together by means of tongue and groove and locked together by cam- lock on each side of the panel to ensure air tight joints. There’s no need of rivets, thus reduce the cost and save the time.
2.Easier and faster installation,can be expended or removed in the future.
3.Perfect heat insulation: High density thermo insulated PUR foam up to 38kg/m³or above for perfect cold-room heat insulation efficiency.
4.Various surface steel choices: Color steel sheet/Stainless steel sheet/ Embossed aluminum sheet,The standard metal sheets are all smooth. Standard color of steel sheet is white-gray, others are natural metallic.
5.Low flammable: Low flammable PUR foam is used in the cold room panel, with fire retardant B2 grade.
6.Highly hermetical: Silica gel are used on the panel edge of the joint parts of each sandwich panel to ensure perfect sealing to avoid the cooling air leakage from the cool room or moisture inside the PU insulated panel for the best refrigeration and frozen storage result.
7.Load bearing: The compressive strength is150kpa above, people can walk on the floor panels and allow trolleys can go in and out.
