The 20 foot wide inside (22 outside roof width) Kootenay steel carport kit combines the natural beauty of wood with the strength and durability of steel. Made in Kelowna, British Columbia, this sturdy DIY steel carport timber frame kit system provides you with the right size and quantity of high strength powder coated steel trusses, post boots, braces and fasteners. You must provide the wood and roofing from your local hardware store to our specs provided. An eaves trough can also be attached on each side. You may also choose to substitute a steel roof for clear or bronze 6 mm polycarbonate roofing panels and use it as a summer gazebo or pergola.

This timber frame style wood and steel carport provides a snow load rating estimated at over 90 pounds per square foot (assuming steel 26 gauge roof) although you are responsible for permitting in your area. Our patented and CSA approved welded steel trusses, post boots and brackets support a 26 to 29 gauge ribbed metal roof. Please note that we can not provide an engineers stamp since each region and installation is different, but we do provide required drawings for permits further below.
