High Desert Post-Frame in the First Atomic City
Post-Frame Building Materials in Arco, ID
Arco is the first city in the world to be lit by nuclear power — and the Butte County seat that serves the ranching operations and nuclear research community stretching across Idaho’s high lava desert. Western Building Supply delivers complete post-frame packages to Arco-area contractors, engineered for the demanding high desert conditions of central Idaho’s most remote plateau.

Butte County is defined by two remarkable features: the vast lava desert of the Snake River Plain and the Idaho National Laboratory complex that occupies a significant portion of the county. Arco’s ranching community runs cattle and sheep across the high sagebrush desert, while INL’s presence brings support contractors, maintenance operations, and the light industrial and service economy that a major research installation generates. Post-frame construction serves both communities: rugged, practical ranch buildings for the desert cattle operations, and the equipment shops and storage facilities that INL contractors and support businesses require.
Western Building Supply serves Arco and Butte County from our Wheatland, Wyoming manufacturing facility. The high lava desert’s building environment is among Idaho’s most demanding: extreme UV intensity, persistent wind across the open desert plain, significant temperature swings between summer and winter, and the alkaline soil conditions common to the Snake River Plain’s volcanic geology. We engineer every package for the specific environmental conditions your Butte County build site presents — not a generic Idaho specification that may miss the particulars of high desert construction.
When Arco contractors need materials engineered for the high lava desert, they call Western.

Why Arco Contractors Choose Western
Extreme High Desert Durability
The Snake River Plain’s high desert delivers UV intensity, persistent wind, and wide thermal swings that test inferior building components rapidly. Our roll-formed steel panels carry a 40-year paint warranty backed by coating systems specified for high-UV, high-desert exposure. The alkaline volcanic soils of Butte County drive specific laminated column treatment requirements that we account for in every package. Your building holds up in one of Idaho’s harshest building environments.
Desert Ranch Infrastructure
Butte County’s cattle and sheep operations build practical, durable structures for a demanding desert environment. Hay storage, equipment shops, lambing and calving facilities, and general-purpose ranch buildings that function in extreme heat and cold without maintenance failure — this is the core of what we build for desert agricultural operations. We understand what ranch buildings need to do, and we engineer and specify accordingly.
