Galvalume SteelHeavy Duty US Steel Galvalume®

AZ55 Galvalume is super corrosion resistant!

Longlife Steel Buildings uses only the toughest steel available to create a strong and durable metal building. More rust resistant than Galvanized steel, this Galvalume steel sheet used in our buildings is 80,000ksi tensile yield carbon steel coated with aluminum-zinc alloy with the addition of silicon by a continuous hot-drip process where the sheeting is cleaned and coated. This coating combination is ideal to protect the steel building from the presence of long-term atmospheric corrosion especially in acid rain enviroments.

The Galvalume steel components are virtually maintenance free because they come with a 35 year warranty against rust perforations. This means no painting, no treating, no unsightly rust holes and no maintenance for over 3 decades!! Simply put up your building and enjoy the peace of mind.

Steel Building ManufacturerMetal Building Roof and Sidewall Panels

Longlife Steel Buildings panels overlap features double benefit!

Our steel arch panels have a 7½" deep corrugation for extreme strength and are precision manufactured so the last 9″ of the panels are smooth and flat so they fit snugly together to eliminate the need for caulking or waterproofing. This overlap makes it easy to connect and bolt the panels together during the assembly process to form a perfect tight fit! They also include a double row of bolts from panel to panel for reinforced strength.

The deep corrugation, heavy gauge of the steel, and overlapping where the panels and arch spans join all combine to produce the most efficient and strongest prefabricated steel building system sold.

One size bolt for entire construction

When constructing your new metal building, there is no need to search for the right size bolt – Longlife Steel Buildings uses only one size nut and bolt for all arch and endwall panels.

Corrosion resistant, high strength high Grade 8 bolts are included with our building kits. The superior coating on the bolts is 10 times more rust resistant than standard commercial hardware when tested in a 1000 hour salt spray test. The bolts all come with an industrial low density polyethylene washer already prefixed to guarantee a watertight seal once the bolt is tightened.
