Technical Data Sheet: Corrugated Sheets for Roofs or for Mezzanine Floors and Walkways

1. Introduction

Corrugated sheets are structural elements commonly used in the construction sector for roof coverings and flooring of mezzanines or walkways. Their main function is to provide support and resistance to variable loads. Below, you will find a detailed technical sheet regarding the corrugated sheets with a width of 700 mm and a length varying between 4 and 8 metres.

2. Composition and Structure

• Base Material: Corrugated sheets are typically made of galvanized or polyester-coated steel. They can also be made of aluminum or stainless steel depending on the needs for strength and durability.
• Type of Profile: The sheets have a corrugated or corrugated profile which gives them greater mechanical resistance and rigidity. The profile may vary from manufacturer to manufacturer.
• Thickness: Generally varies from 0.5 mm to 1.2 mm, depending on the expected load and structural specifications.

3. Dimensions and Measurements

• Width: 700 mm (fret side to fret side).
• Length: Variable from 4 to 8 meters. The length can be customized according to project needs.
• Greek Height: Typically varies between 15mm and 30mm, depending on the design.

4. Mechanical Characteristics

• Compressive Resistance: Corrugated sheets offer good compressive resistance thanks to their corrugated profile, which distributes the load evenly.
• Breaking Load: Depends on the thickness and type of steel. Generally, for a thickness of 0.75 mm, the breaking load can vary between 4 and 6 kN/m².
• Modulus of Elasticity: Typically around 210 GPa for steel, which is indicative of the stiffness of the material.

5. Mathematical Formulas for Optimal Use Parameters

• Max Load (q) = (F * I) / (L * d)

  Where:

  • F = Applied load (N)
  • I = Moment of inertia of the profile
  • L = Length of sheet metal (m)
  • d = Sheet metal thickness (m)

  This calculation helps determine the maximum load that the sheet metal can support without excessive deformation.

• Maximum Deformation (Δ) = (F * L^3) / (48 * E * I)

  Where:

  • E = Modulus of elasticity (Pa)
  • I = Moment of inertia (m^4)

  This formula allows you to calculate the deformation of the sheet metal under load.

6. Workable Materials

Corrugated sheets can be designed to work with various materials, including:

• Support of Light Loads: Ideal for light roofs and floors.
• Coatings and Insulations: Can be coupled with insulating materials to improve energy efficiency.

7. Maintenance

• Regular Inspections: Periodically check for rust, cracks or deformation.
• Cleaning: Remove any debris and dirt to prevent moisture buildup.
• Protective Coatings: Consider applying anti-rust coatings if necessary.

8. Verification of used cars

To determine if a used corrugated sheet metal is in good condition:

• Visually Examine: Check the surface for signs of wear, corrosion or damage.
• Measure Thickness and Length: Check that the dimensions match the original specifications.
• Check Maintenance History: If possible, obtain information on maintenance performed in the past.

9. Sectors of Use

Corrugated sheets are used in various sectors, including:

• Construction: For roofs, mezzanines and walkways.
• Industry: For flooring and support structures.
• Agriculture: For roofing of agricultural buildings and stables.

10. Advantages of Buying Used

• Lower Cost: Used sheets are generally cheaper than new ones.
• Sustainability: Reusing materials helps reduce waste and environmental impact.
• Immediate Availability: Often available immediately with no waiting time for production.

In summary, corrugated sheets represent a versatile and robust choice for a variety of construction and industrial applications. Buying them used can be an economical and sustainable solution, as long as you carefully check their condition and their suitability for the intended use.
