What are wooden cores?

Our durable Scandinavian ISPM-15 pinewood cores (also called wooden rollers, drums, shells, tubes and spools) are always glued with an environmentally safe and moisture resistant wood glue and is unique for this kind of wooden product, because our wooden cores are manufactured for using a square axle, which optimizes the winding process during the production process.
Our wooden cores differ in the following diameter, size and completion:
- The diameter varies from 80 up to 400 mm.
- Length (width) from 70 up to 4000 mm.
- A square continuous tube center from 35 up to 250 mm.
- With glued bonding continuous square steel or aluminum profile tube equipped with steel end lid at both ends.
