Roof

Olympia’s pole barn kits consist of maintenance-free AZ55 Galvalume®. AZ55 which consists of 55% aluminum, 44% zinc and 1% silicon. Since there is more aluminum in the coating it is more resistant to rust. 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.

AZ50, used by our pole barn manufacturing competitors, is an inferior metal making AZ50 a more worthwhile investment. You’ll never have to paint or maintain the roof of your pole building because Galvalume will always have the same luster as it has when it’s first installed.

Our pole barn competitors only offer a 15 year guarantee on the roof of their pole buildings, which only use a zinc coating that eventually will oxidize, fade then rust. Some only use AZ50 that can only provide you with a 20 year warranty.

Fasteners

The capped fasteners used on our pole buildings are made with 18 parts chrome and 8 parts nickel – otherwise known as 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 pole barn roof if they’re incompatible.

These fasteners will not turn dark, black or tarnish. They also will not rust and combined with our AZ55 roof, the pole building will retain its beauty for a lifetime.

Our pole building competitors only use a long lasting alloy head, which doesn't rust, but will tarnish turning dark gray or black. The roof of the pole barn loses its luster and beauty.

Roof Panels

Our pole barn roof panels are made of durable and sturdy steel consisting of an 80 yield, 26 gauge AZ55 Galvalume.

Our steel buidings have a 1½" depth in our corrugation in the sheeting on the roof. The depth of corrugation adds strength to the roof.

The sheeting on the roof of our pole buildings has a depth of 1½" in the corrugation. The depth adds strength to the roof.

If your pole barn is 60' long and every frame is 20’, you will have 3 bays with sheets overlapping at each bay. The panel overlap goes all the way to the bottom of the corrugation and along the bottom like a reversed "L". This prevents water from backing up through the overlap into the pole building, thus preventing leaks and giving you a dry building. The design of this overlap looks like the letter "Z" resembling the purlins on the roof which join the rafters together in the pole barn.

Bending and cracking is prevented in the roof sheeting due to the tremendous strength of the purlin braced roof of the pole building.

Other pole barn manufacturing companies only use 29 gauge steel on the roof, which is lighter than our 26 gauge steel, and only a 5/8" depth of corrugation that does not provide extra strength required for the roof of the pole building.

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 Olympia uses because the water will back up into the pole building.

Paint

The paint used on our pole buildings has a 40 year warranty against chipping, cracking, peeling and blistering. It is a baked-on polyester paint so that the pole barn maintains its color and beauty for a long time.

Our pole building competitors only warranty the roof for 10, 15 or 20 years.

Girts and Purlins

The pole building’s purlins, which are the 8” Zees and 16 gauge beams that join the rafters together, and the girts, which are the 16 gauge 8” beams that join the columns together at the side of the building, have a zinc-galvanized coating applied to it at the steel mill. This is not a primer, but protects the purlins and girts from corrosion and unsightly rust caused by leaking from the roof and sides of the pole barn kit for many years.

Other pole building manufacturers use wooden girts and purlins which will bow or bend causing screws to loosen, sheets to flap and leaks to occur within the pole barn.

Frames

Our pole buildings consist of rigid frame, plate steel and H beam construction. Since no wood is used on the building no warping will occur, there’s no risk of fire nor termites but insurance premiums will be less expensive than it would be for wooden pole barn kits. There is also a 50 year warranty against defects in materials and workmanship on all structural components.

The pole building’s truss does not have a cord going across which means there is complete space within. Birds cannot perch and defecate on the equipment and machinery inside the pole barn, which will save you tremendous costs on maintenance.

Pole buildings manufactured with wooden frames will eventually warp over time. They’re also a fire hazard and could get eaten or damaged by termites and other insects which will raise the costs of insurance premiums for the pole barn.

Other pole building manufacturers use a cord going across the truss width causing loss of space. This can also cause potential damage to your machinery and equipment because birds can perch on the cord and defecate on the stored items in the pole barn.
