Why are Global Steel Buildings superior to wood pole barns and wood pole buildings?
Roof
Global Steel Buildings
Global Pre-Engineered Steel Buildings kits consist of maintenance-free AZ55 Galvalume®. AZ55 which consists of 55% aluminum, 44% zinc and 1% silicon.
This also allows the steel mill to give 25 year rust through warranty on perforation. If a hole develops in a panel, the steel mill will replace it.
Wood Pole Barns
Wood pole barns typically offer only a 15 year guarantee on the roof sheeting. In most cases wood pole barn buildings only use sheeting with a zinc coating that eventually will oxidize, fade then rust.

Fasteners
Global Steel Buildings
Our capped fasteners are stainless steel. They won’t rust and includes a lifetime warranty. It is very important that the fasteners be compatible with the AZ55 or AZ50 because the steel mill will not warranty the wood pole barn roof if they’re incompatible.
Wood Pole Barns
Wood Pole Barn buildings typically use fasteners with an alloy head that will tarnish turning dark gray or black. The roof of the wood pole barn loses its luster and beauty.
Roof Panels
Global Steel Buildings
Our roof panels are made of steel consisting of an 80 yield, 26 gauge AZ55 Galvalume.
Our steel buildings have a 1½” depth in our corrugation in the sheeting. Our extra depth of corrugation adds strength to the roof.
The sheeting on the roof of our steel buildings has a depth of 1½” in the corrugation. The depth adds strength to the roof.
Our panel overlap (called a reversed “L”) prevents water from backing up through the overlap into the Global Steel Building.
Wood Pole Barns
Wood pole barn buildings typically only use 29 gauge steel on the roof, which is lighter than 26 gauge steel, and only a 5/8″ depth of corrugation that does not provide the extra strength the Global Steel building has.
Some of pole barn kit manufacturing competitors use an ‘R’ panel roof, which means the sheeting only overlaps one third of the way into the corrugation. This doesn’t prevent leakage as well as the reverse ‘L’ design that Global Steel uses because the water will back up into the pole building.
Paint
Global Steel Buildings
The paint used on our Steel buildings has a 40 year warranty against chipping, cracking, peeling and blistering. It is a baked-on polyester paint so that the Global Steel Building maintains its colour and beauty over time.
Wood Pole Barns
Wood pole building manufacturer’s typically only warranty the roof for 10, 15 or 20 years.
Purlins and Girts
Global Steel Buildings
Our Buildings purlins and girts are superior 16 gauge zinc-galvanized.
Wood Pole Barns
Wood pole building manufacturers typically use wood purlins and girts which will bow or bend causing screws to loosen, sheets to flap and leaks to occur within the pole barn.
Frames
Global Steel Buildings
Our steel building consists of rigid frame, plate steel and H beam construction. Since no wood is used in our building – no warping will occur, there’s no risk of fire or termites AND insurance premiums will be less expensive than for wood pole barn kits. Our Building has a 40 year warranty against defects in materials and workmanship on all structural components.
Our building’s truss does not need a cord going across which means there is complete unobstructed space within. Birds cannot perch and defecate on the equipment and machinery inside the barn, which will save you tremendous costs on maintenance.
Wood Pole Barns
Wood pole buildings manufactured with wooden frames will eventually warp over time. They can also become a fire hazard and become a target for termites and other insects – raising the costs of insurance. Wood Pole Buildings are more expensive to insure.
Wood pole building manufacturers typically require a cord spanning across the truss width causing tremendous loss of space. This creates a perch for birds – potentially damaging your machinery and equipment.
