This page provides detailed information about the pricing structure of the double layer IBR and corrugated roof sheet roll forming machine. Designed as a cost-effective solution for manufacturers who need to produce both IBR trapezoidal roof panels and traditional corrugated roof sheets, this machine consolidates two complete production capabilities into a single frame — delivering substantial savings on equipment purchase price, workshop space, shipping expense, and ongoing operational costs compared to buying two dedicated single-profile machines.
| Price Factor | Lower Cost Configuration | Higher Cost Configuration | Impact on Price |
|---|---|---|---|
| IBR Profile Width | 762mm or 840mm effective cover | 1050mm or 1100mm effective cover | Wider panels require larger rollers and longer shafts, increasing material and machining cost |
| Corrugated Profile Width | 660mm or 750mm effective cover | 900mm or 1000mm effective cover | Broader wave sheets need additional roller stations and wider frame construction |
| Roller Station Count (IBR) | 14 rows | 18 rows | Each additional row adds one roller pair, shaft, bearings, and sprocket — approximately 3–5% price increase per 2 rows |
| Roller Station Count (Corrugated) | 13 rows | 16 rows | Same principle as above; more stations improve forming quality but increase material cost |
| Main Motor Power | 5.5kW | 7.5kW or servo motor | Higher motor rating costs more; servo adds approximately 15–25% to the base machine price |
| PLC Brand Selection | Delta DVP series | Siemens S7-1200 or Mitsubishi FX3U | European or Japanese PLC brands carry a premium over Asian alternatives |
| Frame Specification | 300H channel steel | 400H H-beam steel | Heavier frame increases structural rigidity and machine lifespan but requires more raw steel |
| Decoiler Capacity | 5-ton manual expansion | 8-ton hydraulic expansion with pneumatic brake | Larger decoiler with powered features increases total line cost |

| Step | Information to Provide | Why It Matters for Pricing |
|---|---|---|
| 1 | IBR roof sheet cover width required (e.g. 840mm, 925mm, 1050mm) | Determines roller diameter, shaft length, and frame width — all material cost drivers |
| 2 | Corrugated sheet cover width and wave count (e.g. 750mm, 7 waves) | Sets the lower deck roller specification and station spacing requirements |
| 3 | Coil material type and thickness range you will process daily | Thicker and harder materials require higher motor power and possibly upgraded chain specification |
| 4 | Target daily or monthly production volume | High-volume operations may benefit from higher motor power and additional roller stations for faster speeds |
| 5 | PLC brand preference (Delta / Siemens / Mitsubishi) and voltage/frequency | PLC brand significantly affects the electrical system cost; voltage must match your factory supply |
| 6 | Destination port for shipping cost estimation | Freight cost varies greatly by destination and container type; we can provide an FOB or CIF quotation |

| Business Scenario | Calculation Basis | Estimated Payback |
|---|---|---|
| Startup roof sheet factory, single shift | Producing approx. 800–1,200 linear meters per day at competitive local market pricing | Machine pays for itself in 6–9 months of steady production |
| Existing factory adding second profile | Currently running one profile; adding IBR or corrugated capability opens a new customer segment without buying a second complete machine | Additional revenue from new profile type typically recovers the machine cost in 4–7 months |
| Import substitution model | Replacing imported finished roof sheets with locally manufactured panels using this machine | Local production cost is typically 30–50% below imported sheet prices; machine investment recovered in 3–5 months |
Before export packaging, each machine passes a comprehensive three-phase inspection. Phase one — mechanical verification: every roller gap is measured with calibrated feeler gauges against the engineering specification; shaft runout is checked with dial indicators at all bearing points; frame alignment is confirmed with precision spirit levels and laser instruments. Phase two — extended dry run: the machine operates continuously at full speed for a minimum of four hours; bearing temperatures are monitored and logged at 30-minute intervals; chain engagement is inspected visually and audibly; every PLC function is tested including start, stop, speed change, length programming, batch counting, and emergency stop. Phase three — live material trial: 50 IBR roof sheets and 50 corrugated roof sheets are produced from actual galvanized coil; every 10th panel is measured for length, rib geometry, wave pitch, and cut edge quality using calibrated digital instruments. Machines must pass all three phases with zero out-of-tolerance results before container loading.
The main machine receives three-layer protective packaging: VCI anti-rust film wrap, high-density foam padding at all corners and protrusions, and heavy-gauge UV-stabilized polyethylene outer shrink wrap. The wrapped unit is bolted to a fumigated ISPM-15 plywood pallet or welded steel skid. The hydraulic decoiler, run-out table, hydraulic power unit, and control cabinet are packed in separate marked fumigated wooden crates. A dedicated accessories crate holds the tool kit, spare parts starter pack, and printed technical manuals. All items load into a single 20GP or 40HQ container. From deposit receipt and profile drawing sign-off, production requires 25–35 working days. Ocean transit time varies by destination — typically 25–40 days to Africa, 15–25 days to Southeast Asia, 35–50 days to South America.
