Girts & Purlins

Great Western's secondary framing is second to none!

Great Western’s secondary structural framing system is designed and fabricated to work perfectly with the primary structural system. The quality of our secondary system is second to none and is a complex component of the steel building system.

Product Benefits

  • Fabricated to strict tolerances for ease of erection
  • 100% Fabricated in the U.S.A.
  • 2/3 more zinc coating than G-30
  • Pre-Punched and No Welds
  • 12, 14 and 16 gauge in any shape configuration available

Comprised of cold formed cee, zee, angle and special shape members, these 100% U.S. fabricated items make up around 50% of the total structural system. The Great Western secondary system is made up of girts, purlins, door jambs, headers and eave struts. Available in a variety of web and flange depths we also use, as a standard, G-90 galvanized 12, 14 and 16 gauge products.

G-90 meets the demanding needs of buildings being used in harsh marine and other corrosive environments. Nearly one ounce of zinc covers every square foot of steel and is 2/3rds thicker than the more common, G-30 products used in the industry.

Great Western’s design and fabrication standards call for a 1/16th inch tolerance for hole locations and 1/8” tolerance for overall length, camber and twist. Our galvanized members are never welded. Welding on galvanized steel damages the anti-corrosive properties of the zinc coating around the welds and wouldn’t allow us to offer our lifetime workmanship and material warranty. Instead, we pre-punch every connection to the tightest tolerances and provide all necessary hardware for installation.

Not only does the Great Western secondary structural system outperform the other systems available, it looks great too. The industry standard secondaries are coated in a red primer and don’t have the anti-corrosive properties of galvanized steel. Like the primary system, our girts, purlins, base angles, and other secondary framing pieces won’t conceal problem areas or rust. This makes areas in need of maintenance easy to identify for the life of the building.
