Arkansas River Valley Agriculture Built Right
Post-Frame Building Materials in Lamar, CO
Lamar is the commercial hub of Prowers County on Colorado's southeastern plains — where the Arkansas River irrigates melon fields, alfalfa, and feed crops that support one of the state's densest concentrations of cattle feedlots. Western Building Supply delivers complete post-frame packages to Lamar contractors, engineered for the hot summers, High Plains wind, and industrial-scale agricultural demands of the lower Arkansas valley.

Prowers County sits in the lower Arkansas River valley where irrigated agriculture and concentrated cattle feeding create one of southeastern Colorado's most active construction markets. The Lamar area supports cattle feedlots measured in tens of thousands of head capacity, irrigated alfalfa and corn along the river, cantaloupe and watermelon operations that have defined the region for generations, and the commercial businesses that serve a farming economy operating at genuine industrial scale. Contractors building here need feedlot processing facilities, commodity storage for corn and silage, equipment shops wide enough for the largest modern farm machinery, and the heated maintenance buildings that keep operations running through cold High Plains winters.
Western Building Supply serves Lamar via US-50 and US-287, approximately 340 miles from our Wheatland, Wyoming manufacturing facility. At 3,622 feet on the open southeastern plains, Lamar sits at low elevation with minimal snow load requirements — but the flat, treeless terrain delivers severe wind exposure that many builders underestimate. Hot summers with sustained temperatures above 100 degrees and intense UV compound the demands on building materials. We engineer every Prowers County package for these actual conditions: wind-rated structural systems for open-terrain exposure, and steel coatings formulated to resist both UV degradation and the heat of southeastern Colorado summers.
When Lamar contractors need materials built for the Arkansas valley's agricultural scale, they call Western.

Why Lamar Contractors Choose Western
Feedlot and Livestock Infrastructure
Prowers County's cattle feeding operations are industrial-scale enterprises, and the buildings that support them need to match. We engineer feedlot processing facilities with the clear spans and structural capacity for heavy daily use, commodity storage for corn, silage, and feed-mixing operations, and livestock handling buildings designed for efficient flow and long-term durability. WBS has supplied materials for agricultural operations across the southeastern Colorado plains and understands what concentrated livestock operations demand from a building.
Hot-Climate Steel and Wind Engineering
Lamar's climate combines two building challenges that many suppliers address poorly: extreme heat and UV exposure in summer that degrades inferior steel coatings, and sustained High Plains wind across flat terrain that drives lateral loads year-round. We specify steel coatings formulated for high-heat, high-UV environments and engineer structural systems for the open-terrain wind exposure classification that Prowers County's flat agricultural land actually demands. Your building performs in both July and January.
