The use of load-bearing trapezoidal sheets

The load-bearing trapezoidal plate can be used as a covering or as a substructure for flat roofs. The sheet metal is anti-corrosion protected on both sides, but if the sheet metal is used as a finishing roof covering, a suitable anti-condensation wave can be installed on the underside to prevent the formation of condensation.

They are suitable for canopies, commercial buildings and agricultural buildings. They are also suitable for roofs with smaller slopes.

Materials for making

The usual materials for the production of trapezoidal sheets are steel, aluminum or copper. The copper ones are the least produced of the three, as these plates come with a high price tag. Trapezoidal panels are produced in different thicknesses, between 0.4 mm and 1.00 mm thick.

Steel

Steel is one of the cheaper materials for the production of trapezoidal sheets, but it needs to be protected against corrosion. Therefore, steel sheets are usually galvanized and then coated with polyester.

Aluminum

Aluminum plates are lighter than steel plates, partly because they do not require corrosion protection. Compared to steel plates, aluminum plates are more expensive to manufacture, which is why they are also less used.

Endurance

One of the great advantages of metal roofs is that they are extremely durable, as they can withstand the impact of strong hail and, with good installation, high wind speeds.

The price

The prices differ according to the material the panels are made of, their thickness and whether they have any additives, such as anti-condensation felt. The prices of trapezoidal sheets start at nine euros per square meter.

Warranty

Trapezoidal sheets are extremely durable, which enables them to have a long service life, and at the same time, providers offer long warranties for them, which can be up to 50 years.

Life span

Trapezoidal sheets are very resistant and have a long service life, which can be several decades.
