Common dimension standard parameters of aluminum alloy access panel.

In use, the size requirement of aluminum alloy for manhole is very important, because the size does not meet the standard, which may affect its use effect. The following are some common size parameters and standard requirements:

1. Length: Generally speaking, the length of aluminum alloy for manhole should be controlled between 200 and 800 mm..
2.  Width: According to the different needs of the train body, the width of aluminum alloy for the inspection port can be adjusted between 70 and 250 mm.. In the specific use, it needs to be selected according to actual needs.
3. Thickness: The thickness of the aluminum alloy for the manhole is usually between 1.6 and 3.0 mm, and the specific thickness should be selected according to the needs of the train body.
4. Tolerance: In order to ensure the use effect of aluminum alloy for the manhole, its dimensional tolerance should also be controlled within a certain range. Normally, the tolerance of length and width should be controlled within plus or minus 0.5mm, while the tolerance of thickness should be controlled within plus or minus 0.1 mm..
