Belt-Winding Cores – entire industries revolve around them
Since 1955, Souhegan Wood Products has been a global leader in the production and distribution of winding cores. Also known as extruded shells, our rugged cores provide unrivaled strength and internal support for a broad range of rubber and industrial belt as well as woven and non-woven textiles during winding, unwinding, and transport.
SWP STANDARD CORES
The strong, reliable backbone of industries around the globe
Sturdier than lumber or cardboard and lighter than steel, Souhegan Wood Products compressed wood particle cores have earned best-in-class status as the preferred core for the belt-winding industry. Our purpose-built cores are designed to transition easily through manufacturing, shipping, and installation – benefiting your bottom line and exceeding your expectations.
SWP CORE STRENGTHS
