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 industry for roofing and flooring of mezzanines or walkways. Their primary function is to provide support and resistance to variable loads. Below, you'll find a detailed technical data sheet for corrugated sheets with a width of 700 mm and lengths ranging from 4 to 8 meters.

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 strength and durability requirements.
• Profile Type: The sheets have a corrugated or corrugated profile that gives them greater mechanical strength and rigidity. The profile can 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 (greek side to greek side).
• Length: Variable from 4 to 8 meters. The length can be customized based on project requirements.
• Greek Height: Typically varies between 15mm and 30mm, depending on the design.

4. Mechanical Features

• Compressive Strength: Corrugated sheets offer good compressive strength 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 Usage Parameters

• Max Load (q) = (F * I) / (L * d)

  Where:

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

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

• Maximum Strain (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:

• Light Load Support: Ideal for lightweight roofs and floors.
• Cladding and Insulation: Can be coupled with insulating materials to improve energy efficiency.

7. Maintenance

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

8. Used Vehicle Verification

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

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

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 sheet metal is generally cheaper than new.
• Sustainability: Reusing materials helps reduce waste and environmental impact.
• Immediate Availability: Often available immediately with no production lead time.

In short, corrugated sheets are a versatile and robust choice for a variety of construction and industrial applications. Buying them used can be a cost-effective and sustainable solution, as long as you carefully inspect their condition and suitability for the intended use.
