Sheet Pile Driving of Hat Type NSP 25H in comparison to commonly used Type 4.

Mer Lion Metals was privileged to be part of Hat Type Sheet Pile trial piling done in Singapore. This was a test to show the speed and efficiency of the Hat Type Sheet Piles. With the right machine, F301 from Giken, a single 25H sheet pile took effectively 8 minutes to be driven through SPT N Value 20 soil conditions for a full 12m. The 900mm width though having more skin friction due to wider surface area, did not have any issues penetrating the soil strata. The increased width provides higher efficiency in weight, piling speed and cost reduction versus traditional sheet piles like Type 3 and 4 being only 400mm in width.
