Aluminum profiles are essentially the product of the extrusion method, but this kind of method does not only appear in one form. Aluminum profiles that are extruded can either be characterized as continuous — for the manufacture of components with a higher length — or semi-continuous — for smaller components or pieces.
There are several tips for you in selecting a high-quality aluminium window. First and foremost, the thickness of aluminium profiles of the aluminium windows should not be less than 1.2mm. Tempered glass or laminated glass are also better than float glass. If you consider the safety and durability of the windows, choose stainless steel hardware accessories (such as screws, hinges, handles, etc.) It is also advisable to choose pulley that is made of POM material. These products have higher strength and abrasion resistance. They are smooth during operation and not easily damaged.
