Interstate Steel Structures - CA & W. AZ

Construction standards in your area:

 The Interstate Steel Structures we offer have framing spaced no more than 5' apart, and braces on every leg, standard.  When installed on concrete, or if you add mobile home anchors for ground installation, these models are Certified and rated to withstand at least 105 mph winds and 20 psf (some models require 12 Ga. framing upgrade)  They come standard with a 30-day workmanship warranty.  If you upgrade to the thicker, 12 Ga. framing, you will also have a 20-year warranty against rust-through on the framing.


Important note:  Horizontal Roofing will have a 6" overhang on the front and rear of the structure (the frame is one foot shorter than the roof).  Vertical Roof models will NOT have an overhang on the front or rear- the roof and frame will be the same length.


Concrete Footings or Mobile Home Anchors are ALWAYS required for Certified Installed Structures!

30 Colors to choose from!

 

There are 30 different colors to choose from, for the ROOF, WALLS, and TRIM.
