The steel frame of an IBC tote — once the inner plastic bottle is removed — makes an excellent firewood storage rack. The cage is strong, off the ground (which keeps wood dry and discourages pests), and can hold approximately 1/3 cord of split firewood. Add a simple roof of corrugated metal or a tarp, and you have a weatherproof firewood shelter for a fraction of the cost of a commercial unit.
This guide covers removing the inner bottle, preparing the frame for wood storage, adding a roof, and how to stack for maximum drying.

Materials
Parts List
IBC Cage Frame (bottle removed)
The steel cage alone — available for free or very cheap when people buy totes and don't want the frame. Sometimes listed separately on Marketplace.
$0–$30
Corrugated Metal Roofing (2 sheets)
4×8 sheets of corrugated metal or polycarbonate. Cover the top and optionally the back of the cage to block rain and snow.
$20–$50
Self-Tapping Screws
For attaching the metal roof to the top cage frame. Hex-head screws with neoprene washers for weatherproof attachment.
$5–$10
2×4 Lumber (optional)
Simple ridge board across the top to create a pitched roof that sheds rain rather than pooling on a flat surface.
$8–$15
Rust-Inhibiting Spray
The steel cage frame is galvanized but edges and cuts rust over time. Spray bare metal with Rust-Oleum to extend frame life.
$6–$12

Build Instructions
Step-by-Step Build
1
Remove the Inner Bottle
Unbolt the top cage brackets and lift the inner bottle out. The bottle sits inside the cage and is held by the top frame ring and four brackets at the base. Remove the base pallet separately — this becomes useful as the floor of your firewood storage. The cage frame weighs about 80 lbs without the bottle and is manageable with two people.
IBC cage frames are often available for free or $5–$15 from people who buy totes and are discarding the frames. Check local farm supply stores and Facebook Marketplace.
2
Position the Frame
Set the cage frame in your firewood storage location — ideally against a wall, under a roof overhang, or in a covered area. The pallet base keeps wood off the ground (critical for drying — ground contact keeps firewood wet). Position with the open front facing south or away from prevailing weather for best airflow.
Keep firewood at least 5 feet from your home's foundation — firewood is a pest harborage site. Never stack firewood against your house.
3
Add a Roof
Cut corrugated metal or polycarbonate panels to overlap the top of the cage frame by 4–6 inches on each side. Attach with self-tapping hex screws through the corrugation peaks into the top cage bars. For a pitched roof that sheds rain, bolt a 2×4 ridge board down the center of the top frame and lean panels on each side to create a gentle slope. Seal any gaps at the back with a strip of foam weatherstripping.
Clear polycarbonate roofing lets light through, which helps wood continue drying even when covered. Metal is cheaper and lasts longer; both work well.
4
Stack Firewood Correctly
Stack with bark side up — bark sheds rain. Leave 1–2 inches between rows for airflow. Don't completely fill the cage — leave 4–6 inches at the front open face for circulation. Alternate the direction of splits in adjacent rows (log cabin style) if stacking multiple rows to maintain stability without the cage walls for support.
Properly stacked firewood in a ventilated covered rack reaches optimal moisture content (below 20%) in 6–12 months for most hardwoods. A moisture meter ($15–$25) lets you test readiness — green wood above 30% moisture burns poorly and produces creosote.
Frequently Asked Questions
A single IBC cage frame holds approximately 1/4 to 1/3 cord of split firewood (a full cord is 128 cubic feet — the cage is about 35–40 cubic feet). For a typical U.S. household burning wood for supplemental heat, two cage frames store enough wood for 4–6 weeks of regular use.
The cage is galvanized steel and resists rust well for many years outdoors. Edges and cut areas are vulnerable — spray with rust-inhibiting paint when you set it up. Ground contact is the main rust accelerator; keeping the pallet base off wet ground extends the life significantly.
Yes — a 275-gallon inner bottle without the cage is useful as a rainwater collection barrel, a mixing tank, or a small pond shell. Check our rain barrel and water storage guides for how to repurpose it.
