Maintenance Tips
-
Clean PVC panels with mild soap & warm water monthly; rinse and dry thoroughly—avoid harsh chemicals, solvents, or abrasive pads.
-
Inspect the swing arms, hinge pins and mounting brackets every 3‑6 months; ensure fasteners are tight and free of corrosion.
-
Verify the panel alignment and tension every quarter; panels should overlap correctly and return fully to the closed position without gaps.
-
Keep the door path and hinge area clear of obstructions (carts, debris, floor buildup) to prevent misalignment or damage.
-
In cold‑storage environments (down to –20 °F / –29 °C rating), check for any heat/lift damage or panel warping twice a year—replace damaged PVC panels promptly.
