Metal Garages Built to Last a Lifetime.
Looking for a metal garage that actually fits your vehicles, your lot, and your budget? Triton Industries designs and installs custom steel garages across our 34-state service area — from compact 20×20 single-car buildings to 40×60 RV-height shop garages with workshop space. Every Triton garage is engineered to your county's wind and snow loads, built with premium G90 galvanized 14-gauge steel framing, finished in your choice of 13+ baked-on colors, and backed by a 40-year panel warranty plus a 20-year frame rust-through warranty. Use the gallery below to see real, recently installed projects, then customize the size, doors, windows, roof style, and color to match exactly how you'll use it.
Why a Triton Steel Garage Outlasts Wood
Wood-framed garages rot, warp, attract termites, and need refinishing every few years. A Triton metal garage is built from 14-gauge or 12-gauge galvanized steel framing with 29-gauge (or upgraded 26-gauge) painted panels — engineered to shrug off rain, wind, and snow for 40+ years with virtually zero maintenance.
Every garage ships with a 40-year panel warranty, a 20-year frame rust-through warranty, and a Limited Lifetime Engineering Certification. That means lower insurance premiums, no repainting, and a structure that holds its value as long as your home.
- Wind Rated to 140+ MPH — Engineered to your county's wind and snow loads. Stamped drawings included on certified builds.
- Fire & Pest Resistant — Steel won't burn, rot, or feed termites — protecting the vehicles and tools inside.
- Lower Insurance — Most insurers offer reduced premiums for non-combustible steel structures.

Choosing the right size matters. Here are the most-ordered Triton garage footprints and what they comfortably fit. Need something custom? We can build any size up to 100 ft wide clear-span.

Fully Customizable — Designed Around How You Use It
No two garages are alike. Configure roll-up doors in any size and position, add walk-in entry doors, frame-out windows for natural light, choose vertical roof panels for snow shedding, insulate for year-round comfort, and pick from 13+ colors for the roof, walls, and trim.
Common upgrades include 12-foot RV-height roll-ups, lean-to extensions for extra parked-vehicle coverage, gable-end vents, ridge caps, gutters and downspouts, and reinforced anchor systems for concrete or ground installations.
Common Questions About Garages
Do I need a permit for a metal garage?
Most counties require a building permit for any enclosed structure. Triton provides stamped engineered drawings on every certified build to make permitting straightforward.
Can I install on dirt, gravel, or concrete?
Yes — all three are supported. Concrete is recommended for heated garages and lifts. We provide the correct anchor kit for each surface.
How long does installation take?
Most garages are installed in 1–3 days after delivery. Larger workshop builds (40×60+) may take 3–5 days.
What's the lead time?
Standard lead times run 4–8 weeks depending on color, size, and your county. We'll confirm at order.
