Key Shipping Risks for Concrete Blocks
Be aware of these 4 common risks when booking LTL freight.
- !Concrete Blocks: High susceptibility to edge chipping and structural cracking during mechanical loading or transit vibrations.
- !Concrete Blocks: Significant weight density issues leading to potential freight reclassification and unexpected carrier billing adjustments.
- !Concrete Blocks: Moisture absorption causing increased product weight, efflorescence, and potential staining of neighboring shipments.
- !Concrete Blocks: Risk of load shifting during transit due to high center of gravity and improper pallet friction.
Packaging Requirements (4 Steps)
Follow these steps exactly to avoid reclassification fees and damage claims.
- 1For safe Concrete Blocks transport: Stack blocks on heat-treated, GMA-grade pallets, ensuring the footprint does not overhang the pallet edges.
- 2For safe Concrete Blocks transport: Secure blocks using heavy-duty plastic or metal banding in a cross-pattern to prevent lateral shifting.
- 3For safe Concrete Blocks transport: Wrap the entire pallet load in high-mil stretch film to contain debris and protect against environmental moisture.
- 4For safe Concrete Blocks transport: Place heavy-duty corrugated edge protectors under banding straps to prevent blocks from fracturing under tension.
