High risk of damage to fabricated tensile membrane fabric panels during harsh handling during installation

There’s a high risk of damage to fabricated tensile membrane fabric panels during harsh handling in uncontrolled environment in factory or site conditions.

Potential Damage Types:

  • Tears and Punctures: Rough handling, especially on uneven surfaces with stones or debris, can easily snag or tear the fabric. Slings used for lifting can also cause punctures if not properly padded or positioned.
  • Abrasions and Scuffs: Dragging or sliding panels across rough surfaces like soil or concrete can cause abrasions and scuffing on the fabric surface in the factory or site, potentially compromising its strength and aesthetics.
  • Wrinkles and Deformations: Improper handling or folds in the fabric. These wrinkles can be difficult to remove entirely or cause fiber damage within the fibers and might affect the final form and tension distribution and strength of the material.
  • Delamination (for coated fabrics): For fabrics with a coating (e.g., PVDF on PVC), rough handling can cause the coating to scratch, compromising its performance and aesthetics.

Preventive Measures:

  • Proper Storage: Store fabricated panels in a clean, dry, and protected area away from direct sunlight, wind, and potential hazards like sharp objects.
  • Protective Packaging: Use appropriate protective packaging materials like cardboard or padded covers to shield the panels to avoid sharp folding during transportation and storage.
  • Lifting Techniques: Employ proper lifting techniques using certified lifting slings with adequate padding or bar to avoid puncturing or abrading the fabric. Trained personnel should handle the panels.
  • Clear Work Area: Maintain a clean and clear work area at the installation site, free from debris and sharp objects that could damage the fabric.
  • Inspection Before Installation: Thoroughly inspect the panels for any damage (tears, punctures, abrasions) before installation.

Consequences of Improper Handling:

  • Compromised Performance: Damaged fabric might not perform as intended under load, potentially affecting the structural integrity and lifespan of the tensile membrane structure.
  • Safety Concerns: Tears or punctures in the fabric can create safety hazards, especially if the structure is used in public spaces.
  • Increased Costs: Repairing or replacing damaged panels can lead to additional costs and project delays.

Conclusion:

Proper handling of tensile membrane panels is crucial to ensure a successful and safe installation. By implementing preventative measures like proper storage, lifting techniques, and clear and clean work areas, you can significantly reduce the risk of damage during harsh handling conditions. Remember, even minor damage to the fabric can have significant consequences for the final structure.
