24 and 36 Wide Aluminum Coil Stock

Aluminum flashing roll is a versatile product used in roofing. It is especially useful for providing waterproofing in specific roofing areas. It plays an important roll in weatherproofing your home. The popular specification is 24 inch aluminum flashing roll and 36 wide aluminum coil.

It uses metal aluminum foil (a hard metal film) as the surface layer, so it has the characteristics of moisture-proof, air-tight, heat insulation, resistance to solar ultraviolet light, and abrasion resistance. Aluminum flashing roll generally consists of three parts, namely the self-adhesive layer, the middle layer and the waterproof surface layer. The thickness is about 1.5mm.

The main raw materials include butyl rubber, polyester cloth, metal aluminum foil, etc. What Haomei Aluminum can offer you is the aluminum foil roll. By choosing a reasonable rolling process, we can fully ensure its quality.

The rolling speed directly affects the production efficiency of aluminum foil. The higher the rolling speed, the higher the production efficiency. At present, the maximum rolling speed of aluminum foil rough and medium rolling mills has reached 2500m/min, but the speed will not increase infinitely. In order to improve the rolling speed, for example to 2800m/min, a series of problems such as vibration and control need to be overcome in mechanical design.

During rolling, the thickness of the aluminum foil is controlled by adjusting the rolling force, rolling speed and controlling tension. During rough rolling, the rolling force is used to control the thickness of the aluminum foil.

During finish rolling, the thickness of the foil becomes thinner as the rolling speed increases; the greater the tension, the smaller the thickness; In order to prevent breakage, the tension is usually selected to be 0.2 to 0.4 of the aluminum foil's conditional yield strength.

During low-speed rolling, special oil is often added to the lubricating oil to adjust the rolling thickness of the aluminum foil. Lubricant and roll condition have a very important impact on aluminium foil quality.

Aluminum foil blanks come from cold-rolled aluminum coils, which are generally pre-annealed at 340 to 480°C and have a thickness of 0.4 to 0.7 mm. During rolling, the deformation rate of each pass is about 50%, and the total deformation rate can reach more than 95%. We have 24 inch wide and 36 wide aluminum coil stock.
