From Concept to Creation, We Build to Last!
Mannon Metal Works is a Lebanon, Missouri based welding and fabrication company serving customers across Laclede County and the surrounding region. We provide shop welding and custom fabrication, fully equipped mobile welding and on-site repairs, heavy equipment repair, and structural welding and heavy steel work for jobs that have to hold up under real use. We’re built for real-world work: farm and ranch machinery, trailers and equipment, gates and railings, brackets and mounts, structural reinforcement, and industrial support projects. When it makes sense to bring the job to the shop, you get a controlled build environment and the best value. When the job cannot move, we roll the truck and come ready with the tools, materials, and experience to fix it on location. Our rates are transparent and match the job type, with a two-hour minimum for mobile service and zone-based travel pricing outside our core service area.
With over 60 years of combined experience, we deliver precision, durability, and reliabilityfor residential, commercial, and industrial projects. Whether you need on-site mobile welding or shop-based fabrication, we provide fast, high-quality service at competitive rates. Call today for a free quote!
