Which type and quality of aluminium window frame is best?

Aluminum windows profile and aluminium doors profile have a series of excellent performances such as high hardness, strong toughness, good mechanical properties and corrosion resistance. The overall weight bearing capacity of the window is strong, wear-resistant and durable.

Wrought iron has a much lower carbon content (usually less than .08%), but it contains small amounts (1 to 2%) of slag, the byproduct of iron ore smelting consisting of silicon, sulfur, phosphorus, and aluminum oxides). The lower mixture of carbon makes the metal more malleable and ductile. As the material is heated, reheated, and hammered into shape the slag is worked out of the iron and the material grows progressively stronger and more fibrous in composition. Wrought iron will often undergo at least about a half dozen cycles of heating and working.
