• Preserve the mechanical properties of conduits and pipes.
• Maintain dimensional accuracy and geometric integrity.
• Prevent deformation, warping, or collapse to ensure installation readiness.
• Protect products from ultraviolet (UV) exposure and excessive heat.
• Minimize damage or loss before installation.
• Protect internal surfaces from contamination and pests.
• Maintain flexibility and prevent brittleness.
• Ensure flexible conduits remain defect-free and ready for use.

• Select a flat, level surface free from sharp objects and away from heavy equipment traffic.
• Store products in a covered or shaded area whenever possible.
• Cover materials with light-colored sheeting while allowing ventilation to prevent heat buildup.
• Avoid direct covering with dark plastic sheets.
• Keep products away from heat sources and chemical materials.
• Maintain a moderate ambient temperature, preferably below 40°C.
