ATEC Steel LLC
About
ATEC Steel LLC, founded in 2006 and headquartered in Baxter Springs, Kansas, is a 100% employee-owned (ESOP) steel tank manufacturer and industrial contractor operating a 160,000-square-foot fabrication facility. The company designs, fabricates, constructs, and tests welded above-ground steel storage tanks and ASME pressure vessels serving the water and wastewater, petroleum, chemical, power, industrial gas, renewables, mining, and dry bulk storage industries. For water and wastewater applications, ATEC builds AWWA D100-21 standpipes and ground reservoirs for potable water and wastewater storage, thermal energy storage tanks, and open-top tanks for equalization and aeration basins. Tank construction follows AWWA D100, API 650, and API 620 standards with appurtenances including inlet and outlet piping, overflow and drain connections, shell manholes (minimum 24-inch diameter), roof hatches, screened vents (4-mesh for birds, optional 16-mesh for insects), pressure and vacuum relief valves, liquid level indicators, and perimeter guardrails. ATEC provides end-to-end project delivery from geotechnical investigation and foundation design (concrete and ring wall) through protective coating application (NSF 61-compliant linings for potable water), field erection, hydrostatic testing, and final inspection. The company also offers tank maintenance and repair services including bottom replacement, shell repair, roof modification, and appurtenance upgrades for existing water and wastewater storage tanks.
Key Products
Large-capacity welded steel storage tanks designed and constructed on-site per API 650, API 620, and AWWA D100 standards for water, wastewater, petroleum, chemical, and industrial gas storage applications.
Smaller welded steel tanks fabricated in ATEC's facility and transported to site, offering faster delivery and consistent quality for projects requiring capacities within transportable size limits.
Code-stamped pressure vessels designed and fabricated per ASME standards for pressurized storage and process applications in water treatment, chemical processing, and industrial gas industries.
Design and construction of concrete and steel ring wall foundations engineered to support tank loads, prevent settling, and provide stable long-term support for above-ground storage tanks.
Application of protective interior coatings and linings to prevent corrosion, maintain water quality, and extend tank service life in potable water, wastewater, and chemical storage environments.
Design, fabrication, and installation of process piping systems connecting tanks, treatment units, and distribution infrastructure within water and wastewater treatment facilities.
Custom steel fabrication services for non-standard tank geometries, appurtenances, and structural components requiring precise welding and quality-controlled manufacturing.
Post-construction hydrostatic testing and inspection services to verify tank integrity, weld quality, and compliance with applicable construction codes before commissioning.
