1. Why Galvanized Chassis Are Lower-Priced AND Zero-Maintenance at Weld-Free Nodes
New buyers often assume galvanized frames cost more than painted frames — in modern cold-formed roll-forming, the opposite is true for two clear industrial reasons:
- FR-G & GR-G Pre-Galvanized Series (DX51D+Z Structural Coil): Formed directly from mill-galvanized steel coils and joined with Grade 8.8 M12 bolts. Because there is zero welding during assembly, the zinc layer is never burned off at corners — eliminating primer/topcoat booth labor and booth curing time.
- FR-P & GR-P Industrial Painted Series: Undergoes surface degreasing, anti-corrosive shop primer, oven/air curing, architectural RAL topcoat (anthracite/white/corporate colors), and protective export stretch-film wrapping on every beam to prevent transit scratches.
- Identical Structural Steel Mass: At any given dimension, FR-G and FR-P share the exact same steel weight (e.g., 341 kg on 3×7 m Flat Roof; 392 kg on 3×7 m Gable A-Roof) and load capacity.
2. Technical & Price Comparison: Galvanized vs. Painted (3×7 m & 2.4×6 m Benchmarks)
| Criterion | Galvanized Series (FR-G / GR-G) | Industrial Painted Series (FR-P / GR-P) |
|---|---|---|
| Surface Protection | Continuous metallic zinc coating (cathodic sacrificial protection) | Anti-corrosive primer + industrial RAL topcoat + export film wrap |
| 2.40 × 6.00 m Flat Roof Price | €900 EUR (FR-G · 279 kg · MOQ 20) | €1,200 EUR (FR-P · 279 kg · MOQ 20) |
| 3.00 × 7.00 m Flat Roof Price | €1,100 EUR (FR-G · 341 kg · MOQ 10) | €1,350 EUR (FR-P · 341 kg · MOQ 20) |
| 3.00 × 7.00 m Gable A-Roof Price | €1,550 EUR (GR-G · 392 kg · MOQ 10) | €1,800 EUR (GR-P · 392 kg · MOQ 20) |
| Sea Freight & Coastal Humidity | Superior (no rust creep in 40' HC ocean transit or coastal air) | Good for inland/urban sites; requires touch-up if scratched on site |
| Corporate Color Aesthetics | Industrial metallic silver finish (can be field-painted with wash primer) | Ready architectural RAL finish matching colored window/panel trim |
3. Climate & Geography Recommendation Matrix
Specify Galvanized (FR-G / GR-G) for sea-freight exports (North/West Africa, Gulf ports), coastal Black Sea/Mediterranean camps, high-humidity sanitary units, and heavy-duty rental fleets. Specify Painted (FR-P / GR-P) when corporate visual branding (anthracite grey RAL 7016 or custom façade trim) is required out of the box.
