What maintenance do outdoor metal structures need in Canada?

Annual maintenance checklist for outdoor structures:

• Spring: Inspect all bolts and connections — tighten any that loosened over winter. Check anchoring. Clean the frame with mild soap and water. Re-install any fabric components stored for winter.
• Summer: Keep the area around the base clear of weeds and debris. Ensure proper drainage. Check for any rust spots on steel (touch up with rust-inhibiting paint).
• Fall: Remove fabric covers, netting, and curtains from soft-top structures. Store indoors. Clear gutters/drainage if applicable. Secure loose items.
• Winter: Clear snow accumulation over 15-20 cm. Check after major storms for structural integrity. Ensure ventilation to prevent condensation.

Aluminum frames (Sojag, Gazebo Penguin) require zero maintenance — they're naturally rust-proof. Galvanized steel (Arrow, ShelterLogic) has a protective coating that lasts decades but should be inspected annually for scratches or damage.
