FAQ
Q. What are the main advantages of using pre painted aluminum sheet in coil for cold store panels?
A:It offers excellent corrosion resistance, which is crucial in the cold and often humid environment of a cold store. The pre painted finish provides an extra layer of protection against moisture and other corrosive elements.
It has a relatively low thermal conductivity, helping to improve the insulation properties of the cold store panels, which is essential for maintaining the desired temperature inside the cold storage facility.
The coil form allows for efficient production processes, enabling manufacturers to cut and shape the sheets according to their specific panel designs with ease.
Q. What types of coatings are used for the pre painted aluminum sheets?
A:Polyester coatings are commonly used. They provide good color retention, durability, and resistance to abrasion and chemicals. For cold store applications, special polyester coatings with enhanced resistance to condensation and low temperatures are often selected.
Fluorocarbon coatings are also an option. They offer even better durability and resistance to UV radiation, which can be beneficial if the cold store has any areas exposed to sunlight or artificial light sources that emit UV rays. These coatings are more expensive but provide longer-lasting protection.
Q.How thick should the pre painted aluminum sheet in coil be for cold store panels?
A.The thickness typically ranges from 0.3mm to 1.0mm. Thinner sheets (around 0.3mm - 0.5mm) may be used for non-structural or interior panel applications where weight reduction is a priority. For panels that need to provide more structural support or are exposed to greater mechanical stress, thicker sheets (0.6mm - 1.0mm) are preferred. The choice of thickness depends on the specific design and load-bearing requirements of the cold store panels.
Q. Can the pre painted aluminum sheets be easily fabricated into different panel shapes?
A. Yes, they can. The aluminum sheets in coil form are flexible and can be cut, bent, and formed using standard metalworking techniques. Manufacturers can use roll forming machines to create various panel profiles such as corrugated, flat, or ribbed shapes to meet the design and insulation needs of the cold store. The paint finish is designed to withstand these fabrication processes without significant damage or peeling.
Q. What is the expected lifespan of pre painted aluminum cold store panels?
A.With proper installation and maintenance, they can last for 20 to 30 years or even longer. The lifespan depends on factors such as the quality of the aluminum and coating, the frequency and severity of exposure to corrosive substances, and the overall environmental conditions inside and outside the cold store. Regular inspections and any necessary touch-ups or repairs to the paint can help extend their service life.
Q.Can the color of the pre painted aluminum sheets be customized?
A.Yes, manufacturers can offer a wide range of standard colors, and in many cases, custom colors can be produced to match specific branding or design requirements. The color customization process involves careful selection of pigments and coating formulations to ensure both the aesthetic and performance characteristics of the painted surface are maintained.
