Depending on their function and the sector in which they are used, sheet metal varies in thickness, size, quality and type. Among the most commonly used materials in industry are:
Stainless steel sheets
Hot-rolled sheets
Cold-rolled sheets
Aluminium sheets
Brass sheets
Copper sheets
Stainless steel sheets are well known for their high resistance to oxidation and corrosion, making them particularly suitable for constant exposure to humid air or fresh water.
This is due to the presence of chromium within the stainless steel alloy which is an element that thinly coats this kind of metal, resulting in a high degree of protection from external chemical agents and oxygen, generating an anti-rust effect.
Stainless steel sheets are used extensively in the food and chemical industries, but also in many other sectors because they can be easily re-formed and re-designed.
Hot-rolled sheets, also known as F1, are steel plates processed at high temperatures which, through the passage between rolls, compress the metal piece in order to obtain a depletion while at the same time causing a lengthening of the sheet.
Cold-rolled sheets, such as sheets with 2B, 2D or BA finish, are initially hot-rolled sheets and subsequently undergo a reduction in thickness through further processing with softening heat treatments.
In this case, metal sheets are particularly malleable and ductile, therefore, suitable for cold forming.
Aluminium is known due to its lightness, flexibility, malleability and resistance, and therefore combined generally with other metals such as copper or manganese, especially in the construction industry.
In addition, aluminium alloy sheets are frequently treated with extra processing to increase their strength and intrinsic properties, especially in the construction industry like "almond-shaped" aluminium sheets are used for walkways or non-slip walkways.
This kind of sheet is often cold forged and generally used in the production of ornamental and artistic objects, in the manufacture of musical instruments or other such applications.
They are undoubtedly the most attractive aesthetically, while their intrinsic characteristics include excellent welding properties.
Copper is known for its high electrical conductivity, the reason why it is widely used in the construction industry. In particular, copper sheets can be used to coat roofs and make gutters and solar panels.
Another sector that benefits from its intrinsic features, especially its antibacterial and antiseptic properties, is the sanitary, plumbing and handicraft sectors where, for example, copper sheets are generally used to make kitchen equipment.
