Heavy paper belts use reinforced thick paper backing combined with uniform abrasive coating, maintaining stable geometry during wide belt operation.
Their predictable wear pattern and consistent scratch formation make them ideal for initial and intermediate sanding stages.
Heavy paper backing sanding belts are positioned as flatness-oriented abrasives for wide belt sanding systems.
Rather than extreme tensile strength or aggressive cutting, they focus on stable contact and surface consistency across large sanding areas.

In wide belt sanding, surface quality depends more on contact consistency than peak cutting force.
Heavy paper backing creates a stable contact interface, minimizing waviness, chatter marks, and localized over-cutting.
