Frequently Asked Questions (FAQ)
1) What line speeds are typical for corrugated sheet roll forming machines in roofing production?
- For 0.35–0.6 mm GI/PPGI: 25–60 m/min with flying cutoff; 15–35 m/min when inline embossing or punching is included. Actual speed depends on coil thickness, profile pitch, and cutoff type.
2) Which substrates and coatings perform best for corrugated roofing in diverse climates?
- Galvanized steel (ASTM A653 Z180–Z275) for general use; zinc–magnesium (EN 10346 ZM90–120) for improved cut-edge corrosion; Al–Zn (AZ150–AZ200) for heat-reflective durability; PVDF or SMP per EN 10169 for high UV exposure; 3000/5000 series aluminum for coastal zones.
3) How can manufacturers minimize oil-canning and panel waviness on corrugated profiles?
- Ensure coil flatness via tension leveling, maintain symmetrical roll gaps, use crowned rolls where appropriate, stabilize line tension, and control lube film thickness. Keep forming strain below ~2–3% in critical radii on prepainted stock.
4) What tolerances are realistic for panel length and corrugation pitch?
- Best-in-class: length tolerance ±1.0 mm (3σ) at 40 m/min with encoder + thermal compensation; corrugation pitch ±0.5 mm using servo feed synchronization and inline vision verification.
5) What’s the most cost-effective automation upgrade for SME plants?
- Add servo flying cutoff with recipe-based length control and auto stacker. Typical ROI: 9–15 months from reduced scrap (<1.5%), faster changeovers (30–50%), and lower labor per m².
2025 Industry Trends
- Electrification of cutoffs and presses reduces hydraulic maintenance and energy use.
