42’-50’ Wide Metal Building Materials

A building so large and versatile must also possess incredible strength and durability. That’s why 42’-50’ wide custom buildings from AA Metal Buildings are constructed of galvanized steel. Using this material has numerous advantages.


Galvanized steel is really strong. No matter what you or the weather throw at it, it will stand strong.


Your 42’ to 50’ wide steel building will serve you well for years and years thanks to the durability and longevity of galvanized steel.


You can interpret this benefit in nearly any way and still be right. Galvanized steel buildings are weather-resistant, resistant to pests, resistant to mold and mildew, and make maintenance a breeze.

With AA Metal Buildings, you have the choice between two frame thicknesses. This will influence the overall strength of your building.

26- and 29-Gauge Sheeting

Walk-in, roll-up, or both? The choice is yours when it comes to the type, number, and location of doors.


From letting in a little sunshine to giving your building a bit more curb appeal, the windows that adorn your 42’-50’ wide metal building are up to you.

Doors and Windows


Whether you enjoy the open air or need to move large items, including frame-outs in your building is a viable option.


Choose from Asphalt, Concrete, Mobile Home, and Rebar anchors to fit your location and needs.


Ensure your building meets local requirements by opting for a certified structure.

Site Preparation for 42’-50’ Wide Steel Buildings

Your building cannot be installed without the site first being properly prepared. This includes clearing and leveling the location.

What Type of Roof do 42’ to 50’ Wide Metal Buildings Have?

Steel buildings of this size come with only one roof option—vertical. This is because they require strength in order to remain durable and safe. The benefits of vertical roofs supply these things and more.

  • Strength – The vertical roof panels associated with vertical roofs make the roof and the structure as a whole much stronger than their horizontal roof counterparts.
  • Weather Resistance – Vertical roofs can withstand substantial snow accumulation. The design of the vertical panels also facilitates improved runoff, helping to prevent excess buildup.
