Roof

Olympia Steel Buildings

Our roof is made of Galvalume® which is AZ55 - 55% of the coating on the roof is made of aluminum, 44% zinc and 1% silicon. The more aluminum in the coating, the more resistance to rusting.

With AZ55, the steel mill gives you a 25 year rust through perforation warranty. Should a hole go through the panel, the steel mill will replace the panel.

With Galvalume you have no maintenance.

Galvalume will not turn grey, but retains the same luster as when it was originally installed, so you will never have to paint or maintain your roof. The cost of AZ55 over AZ50 is well worth it for this exceptional material.

Pole Barns

Our competitors offer only a 15 year guarantee on the roof, and use, in some cases, only a zinc coating which will oxidize, turn dark grey, and rust. Some of our competitors use only AZ50, providing only a 20 year warranty on the roof.

Fasteners

Olympia Steel Buildings

Olympia Steel Buildings use a stainless steel capped fastener which has a lifetime warranty that it will not rust. It is important to know that the fasteners on the roof have to be compatible with the AZ55 or AZ50 or the steel mill will not warranty the roof.

Olympia Steel Buildings capped fasteners are made of stainless steel, which is steel which has 18 parts chrome and 8 parts nickel.

Stainless steel will not tarnish, turn dark or black and will not rust. The roof remains free of rust and retains its beauty for a lifetime!

Pole Barns

Some companies use a zinc fastener, which will rust, therefore, your warranty is not valid.

Other companies use a long life alloy head, which will not rust but which will turn dark grey or black, and the roof does not retain its beauty.

Roof Panels

Olympia Steel Buildings

Olympia Steel Buildings' roof panels are made of 26 gauge AZ55 Galvalume, 80 yield, which makes the steel durable, and hard, so you can actually run up and down the roof.

Olympia Steel Buildings have a 1½" depth in our corrugation in the sheeting on the roof. Olympia' s depth of corrugation adds tremendous strength to the roof.

The sheets on the roof overlap at each bay. If your building is 60' long, you will have 3 bays, as every 20' is a frame.

When the sheeting overlaps at each bay, the Olympia Building 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 building, thus preventing leaks and giving you a dry building.

The design of this overlap, which goes over the top of the corrugation, and to the bottom of the corrugation, and along the bottom like a reverse "L" looks like the letter "Z" resembling the purlins on the roof which join the rafters together.

This purlin braced roof provides tremendous strength and prevents the roof sheeting from bending or cracking.

Pole Barns

Other companies use only 29 gauge steel on the roof, which is 35% lighter than 26 gauge so you cannot have the same strength or durability.

Other companies use only a 5/8" depth of corrugation, which is a full 50% less depth than the 1¼" corrugation and do not provide the strength.

Some companies use an R panel roof, which means that the sheeting overlap goes only one third of the way into the corrugation and not to the bottom and along the bottom like a reverse "L".

This means you will develop leaks, as the water will back up into the building.

This short overlap also does not provide the strength that is required for the roof.

Paint

Olympia Steel Buildings

The polyester baked-on paint we use on the sides and ends of the building has a 40 year warranty against chipping, cracking, peeling and blistering. So your building maintains its beauty year after year.

Pole Barns

Our competitors only warranty the roof for:

10 years
15 years
20 years
40 years - Only Olympia Steel Buildings

Some pole barn manufacturers are Lester, Wicks and Morton

Girts & Purlins

Olympia Steel Buildings

To protect against rusting, the purlins - the 8" Zees, 16 gauge beams, which join the rafters together, and the girts - the 16 gauge 8" beams joining the columns together at the side of the building and C-sections have a zinc-galvanized coating applied at the mill. This is not a primer, which is only an oxide, but a zinc-galvanized coating applied at the mill.

15-20 years from now the purlins and girts will not corrode and leave unsightly rust leaking from the roof and sides of the building.

Pole Barns

Our competitors use wooden girts and purlins, which will bow or bend causing screws to loosen, sheets to flap, and causing leaks.
