If you’ve been tracking prefab trends, you’ve probably heard of the k type house. ZN House builds theirs in Fanxiang Village, Taoyuan Town, Wujiang District, Suzhou, and—speaking frankly—it’s become a bit of a workhorse for rapid deployments: slope roof, modular grid, fast install, predictable costs.
Two macro drivers: faster project cycles and tighter ESG scrutiny. Contractors want dry-in within days, not weeks. Owners ask about reused steel, recyclable panels, lower site waste. The k type house answers both with modular steel frames, screw foundations (often), and panels that can be swapped as needs change. Honestly, the slope roof helps with drainage in monsoon zones—small detail, big impact.
| Item | Spec (≈, real-world use may vary) |
|---|---|
| Module grid | K-Span increments; common footprints 3K×6K, 4K×7.5K |
| Frame steel | Q235B/Q345B, galvanized; welds to EN 1090 principles |
| Wall/Roof panels | EPS, PU, or Rockwool; 50–75 mm (Rockwool λ≈0.038 W/m·K) |
| Roof | Slope 10–15°, color steel sheet, anti-leak flashing |
| Design loads | Wind 0.5–0.7 kN/m²; Snow 0.5 kN/m² (GB 50009 reference) |
| Fire performance | Rockwool up to A2‑s1,d0 (EN 13501‑1); ASTM E84 tested |
| Service life | ≈15–25 years with routine maintenance |
Use cases I keep seeing: construction site camps, emergency/disaster relief, mining/oil temporary offices, pop‑up classrooms, field clinics, and yes—tourism cabins. One project manager told me their k type house dorms stayed 3–5°C cooler than container111s at midday with Rockwool panels and roof vents. Not lab data, but it tracks with the insulation spec.
Panel core (EPS/PU/Rockwool), thickness, eave height, color RAL, floor system (cement board vs. plywood), PVC/Alu windows, solar-ready wiring, guttering, ADA/accessible ramps. The k type house format is modular, so mixing office + dorm + mess hall is straightforward.
| Vendor | Lead Time | Panel Options | Certs (typ.) | Notes |
|---|---|---|---|---|
| ZN House (Suzhou) | ≈2–4 weeks | EPS / PU / Rockwool | ISO 9001; CE components | Slope-roof kits, clear manuals, solid packing |
| Vendor A (regional) | 3–5 weeks | EPS / Rockwool | ISO 9001 | Good price; limited color library |
| Vendor B (export-heavy) | 4–6 weeks | PU / Rockwool | ISO 9001; EN 1090 | Stronger docs; slightly higher cost |
Look for ISO 9001 factory QA, structural checks to GB 50009 (or your local code), EN 1090-aligned steel fabrication, panel fire classification to EN 13501‑1 or ASTM E84, and hardware corrosion checks to ISO 9227. It sounds dry, I know, but it’s the difference between a quick build and a quick headache.
