What Causes Wooden Pallets to Warp and Break?

One of the key factors from the perspective of wooden pallets themselves is poor product quality, including uneven wood, lack of fresh material, insufficient thickness, and loose nails. The processing process is not standardized, with nails being too short and nail caps too small. For instance, a 3-centimeter thick board should use 70 or more nails, but only 57-sized nails are used, leading to shallow nail penetration and easy nail loosening, which can cause damage.

From the user's perspective, failing to prevent overloading of goods, such as placing 2 tons on a pallet that is only designed to hold 1 ton, can easily lead to broken boards. Additionally, excessive force during forklift operations or misaligned sockets can cause a single board to bear an excessive load, resulting in the breakage of the wood and deformation or damage to the wooden pallet.
