The use of excellent raw materials for all the Sa.Fra products guarantees their durability without any kind of maintenance. The production choices of the group are based on in-depth studies of the workability of the materials.


Hot galvanizing treatment: immersion of steel artefacts in a bath of molten zinc kept at an average temperature of 450 °C, which determines the coverage of steel with a subtle and resistant layer of zinc.


Aluminum weighs circa 1/3 of the same volume of copper and steel. Thanks to the multiple surface completions, aluminum turns out to be an extremely resistant material to various weather conditions, easily workable and suitable for being processed both at high as well as low temperatures.


The typical mechanical properties of carbon steel allow a remarkable resistance to corrosion, especially in humid air or marine environments.
