Mechanical Fastening
PALSUN & PALTUF sheets can be fastened with nuts and bolts, providing that several points be kept in mind:
Never use rivets, as they apply excessive force and could cause cracks in the sheets.
Always drill a slightly over-sized hole by 2-3mm (3/32” - 1/8”) to compensate for thermal expansion.
Never use soft PVC washers!
Use neoprene and aluminum washers to distribute the load.
When using mechanical fasteners, they should be evenly spaced to avoid stress accumulation at particular points.
With nuts and bolts, tighten moderately and use only rust-free materials.
Wherever possible, a “floating sheet in frame” is preferable, similar to glass, and without mechanical drilled fasteners.
