Bootstrap Farmer Purlin Hoophouse Upgrade

While it is specifically required for structures wider than 20 feet, adding purlins to smaller hoop houses is still a smart move if you live in an area prone to high winds or heavy snow loads. It provides extra rigidity that helps the frame maintain its shape over time.

The poles are constructed from 16-gauge galvanized steel with a 1-3/8 inch diameter. This material is chosen for its high strength-to-weight ratio and resistance to rust and corrosion in humid greenhouse environments.

Yes, each 20-foot kit comes with the necessary steel components and all required installation hardware. You will only need to provide standard hand tools to secure the purlins to your existing frame.

These side purlins are designed to run parallel to your ridge pole, creating a more robust structural grid. They attach directly to your existing hoop house frame, effectively bracing the arches to prevent bowing or shifting during severe weather.

The sets are sold in 20-foot increments to ensure structural consistency. If your hoop house is longer than 20 feet, you can simply purchase multiple sets and connect them to cover the full length of your structure.
