Hi-Rib Steel: Superior Strength For Superior Buildings

May 28, 2015

At every turn, Morton Buildings is known for giving its customers a competitive advantage. Morton has been a one-stop shop in custom construction for generations, helping hundreds of thousands of our customers discover the benefits of ownership found only in a Morton.

Morton Buildings Hi-Rib steel has been a trademark of Morton’s industry-leading buildings for decades. A critical element in many of Morton’s buildings, the commercial-quality steel provides superior strength and dependability.


Roll formed at one of Morton’s six manufacturing plants throughout the United States, Morton’s steel is .019 inches thick, or 26-gauge, with a one-inch tall major rib, providing added strength over the typical steel from a competitor that is .015 inches thick with five-eighths of an inch major rib.

Two minor ribs between each one-inch major rib add even more strength to the steel. The steel panels are fastened to purlins and nailers through the major rib, allowing water to flow away from fastener.


A coating of zinc or a mixture of zinc and aluminum is also applied to Morton’s steel, protecting against rust, corrosion and other various elements. Morton offers both galvanized and galvalume coated steel.

Morton also uses the FLUOROFLEX 1000 paint system, consisting of several layers of protection and a 70% PVDF top coat or color coat that is weather and corrosion resistant. Morton provides more than a dozen different colors, delivering a wide range of color combination options between the building exterior, wainscot and roof.

It all adds up to deliver a unique blend of beauty of durability.


Additionally, Morton has developed a variation to its interior steel to enhance the customer experience. Morton’s acoustical steel has been used as an efficient sound insulation system in building interiors. The innovation is especially helpful in Morton buildings that may encounter loud noises, such as massive farm storage facilities or smaller personal workshops.

The acoustical steel is installed with perforations in a band in and/or around the ceiling of the building. Interior noise ultimately encounters sound-absorbent materials in the wall and ceiling cavities, improving sound quality throughout the structure.


The praise for the technology and its functionality is virtually unanimous.

“The quality of the steel, you know, has held up very well in the conditions that we live in,” Morton Buildings owner Ronnie said of his building in a coastal North Carolina community that regularly combats salt in the atmosphere near the ocean. “The gauge of the metal that they’ve used – I like that it’s a thick gauge metal, very sturdy and very stout.

“In the boarding kennel, we deal with a lot of noise,” said Morton owner Robb when asked about the sound inside his Morton animal care center in Ohio. “(The acoustical steel) cuts the noise quite a bit. You hardly notice it outside the building and that was our main concern because we’re right next to a residential area.”

“The selection of the acoustical panels was very important to us, and to try to understand how that would really deaden the sound,” Morton owner Ron said of interior space used as a gymnasium inside his Morton church. “The building itself is very acoustically adequate. It holds concerts very well, and during wedding receptions, conversations can be held around tables without a lot of background noise.”

“This is a well-constructed building,” boasted Chuck, a Morton owner of a farm in North Carolina. “This building withstood two hurricanes and a major hail storm in the same year with no damage.”
