Corrugated sheets offer two indispensable advantages, which make them perfect structural elements for a series of applications: from roofs to floors, passing through coverings and false ceilings. Let’s find out more with the help of the experts of the Sandrini Metalli company.
Lightness and strength: these are the two main characteristics of corrugated sheets, construction elements that are highly appreciated in all branches of the construction sector because they allow excellent results to be obtained with a considerable saving of costs and time . Corrugated sheet: a brief definition
The corrugated sheet is, by definition, a corrugated metal sheet, with a “Greek” profile: the choice of this profile is not merely aesthetic, but responds to very specific requirements of mechanical resistance. Indeed, it is precisely the fret that increases the resistance of the sheet to any bending effort .
In fact, the profile of the ribs responds to the same structural logic of the arch: thanks to the ribs, the weight that rests on the sheet is uniformly distributed over the entire surface, thus maximizing the load that the sheet itself is able to support.
It is therefore clear why corrugated sheets are so popular in the construction sector: it is a simple , effective and relativelyeconomical to make strong and durable covers. The corrugated sheets also have the advantage of the speed of intervention: they are prefabricated but in any case highly customizable, characteristics that make them immediately and easily applicable in the areas of use.
The materials with which a corrugated sheet can be made are different:

  • Galvanized steel
  • Aluminum
  • Aluzinc
  • Copper
  • Stainless steel
  • Magnelis

Each material is associated with different chemical-physical characteristics that make it more suitable for one application rather than another. Galvanized and pre-painted steel, for example, is ideal for floors and collaborators ; steel and, to a lesser extent, aluminum are instead more used for roofing and cladding of roofs and floors
. Copper is appreciated above all for its aesthetic performance : as a coating or as a base material, copper always strikes for its its amber and warm shades, its ability to reflect sunlight creating aesthetic effects.
Among the innovative materials we mention the Magnelis: the corrugated sheets made with this material are made of steel with a zinc and magnesium coating, an extremely resistant solution also ideal for coastal and maritime environments. In fact, Magnelis resists corrosion and the attack of acidic substances, making it ideal for application in places exposed to the salty sea air . The advantages offered by the use of corrugated sheets
In addition to the aforementioned mechanical resistance, which derives from the typical shape of the corrugated sheet, this type of construction element also has other important characteristics:

  • It is very light , and reduces the weight of the entire supporting structure
  • As a result, it is easy to transport and quick to install
  • It is resistant to extreme temperatures , which is why it is an excellent alternative to porous roofs that expand and crack after repeated changes in temperature
  • It is waterproof and resistant to atmospheric and chemical agents
  • As a result, maintenance costs are practically zero.

When and where the corrugated sheets can be used
For floors and false ceilings, we have said, but also roofing and cladding: the range of applications of corrugated sheets is very wide, both in the civil and, above all, in the industrial sector . In fact, their greatest application concerns industrial warehouses, large public spaces and warehouses and, as we have seen, includes decorative uses especially in the copper version or in the painted variants.
Specifically, there are roofing sheets (roofs), large spans (very large internal roofs), for structural floors , for claddings (facades) and forfalse ceilings (velari).
