Cold Room Panel Weight Calculation
Weight alone is not a fundamental variable, but assuming that the basic components of cold storage panel materials today are painted galvanized sheets and polyurethane filling; understanding what you are buying and the cost of the goods you are buying; helps you understand the quality of the products in the offers you receive.
Do You Know the Quality of the Products You Purchase?
The factors that determine the weight in Cold Room Panels include the weight of the painted galvanized sheet used and the density of polyurethane foam. You can calculate all these variables yourself with the “Tunelgroup – Panel Weight Calculation” table prepared with the mathematical formulas below. Trust the math! What about the offers you receive? It is up to the buyer to make sure that you are dealing with an honest and knowledgeable seller. Today, many brokerage firms introduce themselves as factories and claim to sell quality products at low prices. The values given may represent the weight of the highest quality materials. However, scales and mathematics do not make mistakes.
Calculating the Weight of Painted Galvanized Sheet Metal
Today, the labels of all rolls offered by manufacturers are measured according to the "finished sheet thickness on the horizontal plane". Therefore, do not forget that the sheet thicknesses in the market have a tolerance margin of minus 5-10% of the specified sheet thickness. However, these raw sheet thicknesses can reach the sheet label value with the grammage and thickness of the zinc gr/m2 coatings and paint gr/m2 coatings applied on them. For example, the single metal thickness of a sheet with a label value of 0.50 mm can start from 0.45. This situation can occur in the form of the metal thickening with the thinning of the sheet, or with the thinning of the metal with the thickening of the sheet, or completely due to the sensitive and different adjustments of the manufacturers.
Calculating the Weight of Polyurethane Fillers
The most important material in Cold Room Panels is polyurethane fillings. Because the main element of the boards is to ensure that the products stand upright or vertically for a long time and firmly, while the presence of Polyurethane means an insulated area. Although the kg/m3 change in Polyurethane filling according to the change in sheet thickness seems like another option in terms of reducing costs at first, it means reducing the insulation, which is the main function of the cold storage. The value declared by the manufacturers for the standards in Polyurethane filling is stated as 40 (±2kg/m3). However, it is doubtful whether this data is entered over 40, 38 or 42 in the injection machine. Perhaps there is no clear explanation or way to know whether it is less than these values. Except for mathematics and scales!
Stay away from fake manufacturers and sellers who do not know what they do, what they offer, or who present themselves as factories. Just like a cold storage unit isolates the heat from the inside!
