Block pallets are much more labor intensive than stringer pallets and require a different collection of machinery to both process the lumber and construct the pallet. They also use different kinds and styles of nails than stringer pallets. Block pallets often use ring shank and clinch nails; most block pallets have been built using softwood lumber, which is one of the major reasons why ring shank nails are common. Stringer pallets are often constructed with drive screw nails, a style of nail that is common in hardwood pallets. Hardwood lumber is most often used when building stringer pallets.
We prefers block pallets and principally uses block pallets in its pool systems.
