Which construction board is right for your project?

Strength and load capacity:
HSD features higher density and a three-layer construction → built to withstand extreme loads. JSD is lighter, yet still strong and stable.
Applications:
HSD: Load-bearing structures, shelving, heavy-duty floors, and components exposed to extreme stress.
JSD: Floors, walls, packaging, furniture – versatile applications.
Moisture resistance:
Both boards are moisture-resistant, but HSD offers lower swelling and greater overall durability.
Weight:
HSD is noticeably heavier → ideal for applications where weight is not a concern. JSD is lightweight → easier to handle.

“StrongBoards – because we know that solid foundations are more than just concrete.”
