When purchasing a commercial walk-in cooler in Charleston, SC, some of the most important features that affect the performance are the materials that it is made of. The two main insulation materials that are used for walk-in coolers are Extruded Polystyrene and Polyurethane. Extruded Polystyrene, which is also used for underground concrete foundation, has the strength of up to four times that of Polyurethane. It also has great moisture resistance and is the ideal insulation for commercial walk-in coolers.
Another other main feature is the metal skin of the walk-in cooler. Galvalume is steel coated with a combination of aluminum and galvanizing material. Although it has the strength of steel, it is 12 times more corrosion resistant than galvanized. It is less expensive than some of the other materials used but has great value. The G90 Galvanized Steel used to be the most popular choice for walk-in coolers, but with increasing prices, it has lost some if its popularity. It is strong and more dent resistant than aluminum, but can develop “white rust” if it is not installed or maintained correctly. Stainless Steel is the most expensive of all the metal skins, but it is also the strongest and least corrosive of all the metals.
