A FumoFlow grain shed consists of a heavy-duty, hot-dip galvanized Action shed frame, which requires little to no maintenance.

The main maintenance consideration is the tarp and the panel flashing.

For example, the tarp lifespan depends on how often it is deployed and how it has been handled over time, particularly whether it has been cut and taped during fumigation and stored correctly.

Routine maintenance typically includes:

• Inspecting tarp for wear or damage before and after fumigation
• Checking panel flashing remains intact, sealed and safe to walk on
• Ensuring fans, ducts and vents are clear and operating correctly

Overall, maintenance is comparable to a standard Action grain shed, with additional checks focused on the tarp and components used during fumigation.
