An excellent example of the limitations is how large a hinged window’s opening element can be. Most aluminium windows only go up to around 1.2 m or 1.5 m, with side-opening windows even smaller at 600 mm or 900 mm. So you won’t find extra-large opening windows beyond these sizes.
Aluminum alloy profiles have the advantages of light deadweight, high strength, corrosion resistance, small deformation, strong fire resistance, etc., with a service life of more than 50 years.
