If you’re comparing modular garages prices, here’s what I’m seeing in the market this year: solid kits from reputable factories have become more standardized, lead times are shorter, and the smarter money is going to well-engineered prefab systems like ZN House’s T Type Prefab House. It’s built in Fanxiang Village, Taoyuan Town, Wujiang District, Suzhou City, China—and yes, the address matters when you care about supply chain transparency and factory QA.
Price first, because everyone asks. For a single-bay garage (≈18–24 m²), ex-factory shell kits tend to land around $60–$120 per m²; turnkey, you’re often looking at $3,500–$9,000 before foundation and local permits. Two-car setups (≈36–45 m²) scale efficiently. Shipping and on-site install still swing the total—freight can add $900–$2,500 per container111, while regional install crews often quote $10–$25 per m². To be honest, options like sectional doors, rockwool panels, and thicker steel bump the number, but for good reasons: performance and life-cycle cost.
| Frame | Cold-formed galvanized Q235B steel, Z275 coating, bolted system |
| Wall/Roof Panels | EPS/PU/Rockwool sandwich; 50–100 mm (λ ≈ 0.035–0.040 W/m·K for PU) |
| Span & Size | Custom modules; common single-bay 3×6 m; two-bay 6×6–7.5 m |
| Loads | Wind up to 50 m/s with proper anchoring; snow ≈ 0.75–1.5 kN/m² (project-specific) |
| Fire & Safety | Panels tested to ASTM E84; design to ASCE 7/IBC (local adaptation required) |
| Corrosion | ISO 12944 C3 strategy; optional higher-class coatings for coastal installs |
| Factory Test Data | Panel U-value ≈ 0.35–0.55 W/m²·K (by thickness); acoustic drop 25–30 dB (indicative) |
| Service Life | ≈15–25 years with routine maintenance; longer with enhanced coatings |
Materials arrive as certified coils and profiles; CNC cutting and roll-forming keep tolerances tight, then bolt holes are punched for fast field assembly. Panels are laminated under controlled pressure; each batch is checked for density and adhesion. Typical QA includes torque checks, coating thickness tests, and panel fire/smoke verification (ASTM E84). Before shipping, modules are pre-assembled dry to confirm fit. Real-world cost swings with steel thickness, insulation choice (EPS vs PU vs rockwool), door spec, and local code upgrades. Expect adders for snow-country reinforcement and high-wind anchoring.
| Vendor | Typical Price | Lead Time | Notes |
|---|---|---|---|
| ZN House (T Type) | $60–$120/m² (shell kit) | 2–5 weeks fab + freight | ISO 9001 factory; EN 1090 steel processing; good documentation set |
| Local Builder (custom) | $120–$220/m² | 4–10 weeks | Simpler permitting; higher labor cost, bespoke detailing |
| Generic Importer | $55–$95/m² | 3–8 weeks | Check panel fire reports and steel certificates carefully |
Common scenarios: home garages, small auto-detail bays, farm storage, last-mile logistics shelters, even pop-up motorcycle workshops. A recurring customer line I hear: “It went up in two days.” Not magic—just pre-drilled connections and light equipment. One caveat: permit drawings must reference local codes (ASCE 7 loads, IBC 2021), which can add a few hundred dollars but often saves weeks. If you’re benchmarking modular garages prices, include foundation (slab vs piers), doors, insulation thickness, and electrical rough-in.
Compliance matters: look for ISO 9001 factory management, EN 1090 steel conformity, and panel fire documentation (ASTM E84 or EN 13501). ZN House provides project packs and can tailor drawings to local loads. If total value versus modular garages prices is your metric, the T Type Prefab House is, in my view, a sensible balance of cost, speed, and durability.
