Steel Arch Workshop Kits
100% Clear-Span Metal Arch Workshop Buildings
Galvalume Construction. 35-Year Warranty. Factory-Direct Pricing.
When you're looking for a better workshop option than a cramped pre-existing garage or open-air space that just doesn't have the space and features you need, there's no building better than a steel arch workshop from ArchBuildings.com. Because our metal arch building kits are 100% clear-span, every single square foot inside your arch workshop is usable — from wall to wall, floor to ceiling.
A Workshop With No Wasted Space
Want to work on cars? An automotive lift fits perfectly under the soaring clear-span ceiling of an arch workshop. Need to hang pegboard, lighting, ceiling fans, bikes, kayaks, ladders, or tool storage from the roof and walls? Not a problem — our metal arch buildings have no interior posts, trusses, or columns to design around.
Whether you're outfitting a serious automotive shop, a woodworking studio, a fabrication space, a small-engine repair bay, or a backyard hobby workshop, an ArchBuildings.com steel workshop kit gives you a clean, code-friendly, weather-tight building that you can customize to fit exactly how you work.

Why Choose an ArchBuildings.com Steel Workshop
Premium materials, smart engineering, and decades of manufacturing experience
100% Clear-Span Interior
Every inch of your steel arch workshop is usable space. With no interior columns, trusses, or load-bearing walls, you can install lifts, run benches wall-to-wall, mount overhead storage, and reconfigure your layout any time your needs change.
Built From Galvalume Steel
Our metal arch building kits are made completely of Galvalume and assembled with premium grade 8 bolts. That means superior corrosion resistance and the kind of long-term durability you simply won't get from “the other guy's” steel products.
Step-by-Step Installation Manual
Every steel workshop kit ships with a detailed installation manual that walks you through every stage of construction — complete with a tool list, step-by-step instructions, and helpful tips and tricks for the sturdiest possible build.
Engineered Plans Available
If your area requires building permits and you need engineered drawings of your metal arch structure, just ask. Engineered plans don't ship standard, so be sure to request them through your sales representative when placing your order so your workshop project sails through permitting.
