A. Layered Stacking

• Separate each tile with a protective film or foam sheet to prevent scratches.
• Stack tiles in uniform bundles (usually 500-600 pieces per crate) to avoid shifting during transit.

B. Wooden Pallet or Metal Frame Crates

• Use durable wooden pallets or metal crates to provide structural support.
• Secure tiles with plastic straps or steel bands to prevent movement.

C. Protective Wrapping

• Plastic shrink wrap around the entire stack to protect from dust, moisture, and weather conditions.
• Optional: Waterproof covers for added protection during long-distance shipping.

D. Accessories Packing

• Ridge caps, barge covers, and flashing should be packed separately in protective packaging.
• Small accessories like nails and fasteners should be boxed securely to prevent loss.

 

2. Loading and Transportation Guidelines

A. Optimizing Container Space

• Typically, a 20ft container holds 5000-7000 pieces of roof tiles.
• Accessories and small items are loaded in side compartments or top sections to maximize space.

B. Securing the Load

• Use wooden braces and padding to prevent movement inside the container.
• Secure pallets with ratchet straps for added stability.

C. Transportation Modes

• Sea Freight: Most economical for bulk orders. Tiles should be moisture-protected.
• Truck Delivery: Ideal for domestic transportation; ensure road stability.
• Air Freight: For urgent orders, though costly. Packaging must be reinforced to withstand handling.

 

3. Unloading and Handling Precautions

Use a forklift or crane to unload pallets safely.
