The top of a thermoplastic pallet has a rectangular frame to which the pallet deck is directly or indirectly attached. The edge of the deck is spaced apart from the outer edge of the frame. The frame comprises bridge parts which span the openings between columns into which forks may be inserted for lifting of the pallet. The plastic bridges are designed for absorbing horizontal impact loads. Each bridge has several lengthwise impact absorber zones of differing cell configuration and thus differing compliance to horizontal impact loads. A metal stay runs along the outer edge of each bridge, for distributing impact forces, and for improving the resistance of the pallet top to impact loads. A stay may be anchored by its ends at the opposing ends of a bridge, and or along its length by engagement of perforations in the stay with plastic features distributed along the length of the edge of the bridge.
