Spike grid timber connectors are engineered to enhance joint strength and rigidity while at the same time simplifying assembly procedures. Timber structures in which spike grid connectors are utilized include decks, pole frame buildings, pilings, wharves, and bridges or trestles. They are also used to advantage in the construction of pole-supported “building platforms” for conventional building of homes, resort buildings, and other structures situated on hillsides as well as over or near water. Flat spike grids are used between sawn timbers, while single curved spike grids are used between round piles or poles and sawn members. Spike grids are manufactured from malleable iron in accordance with ASTM A47 grade 32510.
