Aluminum Alloy Door and Window Handheld Thickness Gauge
In home decoration, aluminum alloy doors and windows are often used to package balconies. It is widely used in the field of construction engineering. It has the characteristics of beautiful appearance, high strength and sealing.
At present, "aluminum alloy doors and windows" (GB/T8478-2008) stipulates that the minimum measured wall thickness of profiles for the production of aluminum alloy doors and windows is not less than 1.1mm. However, in the current aluminum alloy profile market, some manufacturers have reduced the thickness of the aluminum alloy profile in order to pursue profits, which makes it easy to damage the surface or deform the doors and windows. This action greatly reduce the wind pressure resistance of the aluminum alloy doors and windows.
The surface coating of aluminum alloy doors and windows can protect the surface of the aluminum alloy profile. There are four kinds of surface treatment methods such as oxide film, electrophoretic painting, powder coating and fluorocarbon coating.
However, due to the different surface treatment methods, the cost of the handheld thickness gauge will vary. Therefore, the choice of surface coating for aluminum alloy doors and windows should be considered according to the climatic conditions, location, grade and economic conditions of the building.
For example, the oxide film should not be used in areas where the acid and alkali are more serious. In areas such as coastal areas, which are severely affected by sea breeze, thicker coatings are required. A handheld thickness gauge with wide measurement range is required.
To measure the surface coating of aluminum alloy doors and windows, you can use Linshang handheld thickness gauge. There are handheld thickness gauges with different measurement ranges. The instrument uses magnetic principle and eddy current principle. The eddy current thickness measurement is suitable for the measurement of the coating on non-magnetic metal substrate and anodized layer.
