To make uPVC doors and windows, three, four, and five-hole profiles are used, but in fact, the number of holes does not determine and ensure the quality of a uPVC profile, perhaps a five-hole profile is of much lower quality than a single profile. There should be three holes, therefore, the quality of a uPVC profile is determined by the composition of the profile, not the number of holes.

In Iranshahr Asman complex, in order to maintain the competitiveness in terms of price with existing and common products in the market, galvanized steel with a thickness of one millimeter is used, although the standard and technical recommendation is to use galvanized steel with a thickness of 1.25 to 1.5 millimeters. And in the floors above 5, the thickness is 2 mm, and in case of need or agreement with the employer, thicknesses of 1.25 and above are used in the Asman Iranshahr complex for the construction of UPVC doors and windows.

Asman Iranshahr Group is the official representative of upvc door and window assembly of two brands, Hoffmann and Schaefer
