A pallet having an upper deck and a lower deck secured by supporting block members. The upper deck may include a plurality of board members and may be provided with at least one lead board operable to serve as an energy attenuator. The lead board may comprise a composite material and may be formed using pultrusion techniques. The lead board may be separated or spaced from an adjacent board member by a gap or scallop type area and may be operable to flex inwardly or otherwise upon impact to absorb energy. The gap or scallop type area may be suitable to operate in combination with the lead board as a handle mechanism for grabbing or lifting the pallet. The lead board may also be used to attach shipping straps.
