we typically use one-inch square posts core drilled and set in hydraulic cement when we’re installing railings. For fencing, we use heavy duty steel posts that we galvanize, prime, and paint, set into concrete footings. The environment of your property may influence preparations as well: for instance, galvanizing is particularly important if the structure is near water.
When selecting aluminium windows, we often pay more attention to the thickness of the aluminium profiles and glass. We often overlook the importance of the hardware accessories such as hinges, locks, handles, levers, etc. Without them, windows cannot be assembled and perform well and may lead to defects. In fact, our country has specified certain standards for aluminium windows. So, when selecting one, you should make sure that the thickness, strength and oxide film of the aluminium used for high-quality aluminium windows meet our national standards.
