The LC-MR-PRO-1500 High-Speed Automatic Metal Roofing Roll Forming Machine delivers up to 40 meters per minute of precision-formed roofing sheets with integrated auto-stacking and servo-driven flying shear. Engineered for large construction contractors and dedicated roofing material manufacturers supplying major infrastructure projects across Southeast Asia, this production line transforms high-volume roofing from a labor-intensive bottleneck into a streamlined single-operator process. With GCR15 bearing steel rollers, a Siemens S7-1200 PLC, and a monoblock CNC-machined frame, the LC-MR-PRO-1500 provides the throughput, consistency, and uptime required for stadium roofs, industrial parks, and residential township developments.

Contractor Pain Points & Our Solutions
Pain Point
Slow output creates delivery bottlenecks. Standard 8-15 m/min machines cannot meet deadlines for projects needing 10,000+ m² of roofing per week. Production becomes the critical path, delaying site work and triggering penalties.
Our Solution
25–40 m/min production speed — 3-5x industry average. A single shift delivers 12,000–18,000 m² of finished roofing sheets. Multi-shift operation meets the demands of the largest ASEAN infrastructure projects without subcontracting.
Pain Point
Manual material handling inflates labor costs. Traditional lines need 3–4 workers for stacking, exposing them to sharp sheet edges and repetitive strain. Labor availability in Southeast Asian industrial zones is increasingly unreliable.
Our Solution
Integrated pneumatic auto-stacker — one operator runs the entire line. Handles sheets up to 6 m at full production speed, stacking to 1,200 mm height with automatic alignment. Labor requirement drops from 4 workers to 1, with zero manual sheet handling.
Pain Point
Inconsistent sheet dimensions damage reputation. Length drift during long runs causes on-site fitting problems and material waste. Project owners lose confidence when deliveries vary batch-to-batch.
Our Solution
Servo flying shear with ±0.5 mm closed-loop accuracy. Carbide blade rated for 500,000+ cuts. GCR15 rollers maintain profile consistency across 100,000+ linear meters. Digital quality logs included with every production batch for project documentation.
Pain Point
Downtime during peak season means missed deadlines. Machine failure in the middle of a large project triggers liquidated damages and reputational damage that takes years to recover from.
Our Solution
Industrial-grade components with documented MTBF ratings. Redundant sensors and modular design for rapid troubleshooting. Optional 4G remote diagnostics module. Critical spares shipped within 48 hours to all ASEAN capital cities under 24-month comprehensive warranty.
Pain Point
Complex job scheduling across multiple sheet sizes. Large projects demand varied sheet lengths and profiles, creating production planning chaos and costly changeover waste.
Our Solution
Siemens S7-1200 batch management with job queue. Pre-load multiple orders with different lengths and quantities. The system auto-executes the queue with zero-changeover continuous production. Export production reports to USB for client documentation.
Key Features
40 m/min Production Speed
15 kW main drive with closed-loop VFD. Delivers 12,000–18,000 m² per 8-hour shift. Hydraulic decoiler and 7-roller leveling station eliminate material feed bottlenecks.
Servo Flying Shear
Servo-driven cutting carriage synchronized to line speed. Carbide blade rated for 500,000+ cuts. Automatic blade gap adjustment based on material thickness input.
Integrated Auto-Stacking
Pneumatic stacker with programmable height and alignment. Handles 1.5–6 m sheets. Automatic ejection onto roller conveyor for forklift pickup.
GCR15 Bearing Steel Rollers
Premium SUJ2-equivalent steel, hard chrome plated, HRC 60–64. Mirror-polished surfaces for zero sheet marking. Superior wear resistance vs. standard 45# steel.
Siemens S7-1200 Smart Control
12-inch color HMI with batch management, job scheduling, and optional 4G remote monitoring. Generates shift production reports for project management.
Monoblock CNC-Machined Frame
Single-piece welded and stress-relieved main frame. 25 mm wall thickness. CNC-machined roller mounting surfaces eliminate alignment drift under high-speed loads.
Full-Line Integration
Turnkey system: 10-ton decoiler + leveler + forming unit + flying shear + auto-stacker + exit conveyor. All stations synchronized via central PLC.

Applications
The LC-MR-PRO-1500 is purpose-built for large-scale infrastructure and commercial roofing across Southeast Asia:
- Industrial park warehouses — standardized roofing across hundreds of buildings in Thai, Vietnamese, and Indonesian manufacturing zones
- Stadiums and convention centers — where consistent sheet quality and tight dimensional tolerances are non-negotiable
- Residential township developments — thousands of identical roofing sheets delivered on a just-in-time basis
- Airport and port terminal buildings — demanding full material traceability and quality documentation
- Dedicated roofing sheet plants — supplying distributor networks across multiple ASEAN countries
Compatible with JIS G3302 galvanized steel, ASTM A792 zincalume, and locally sourced PPGI from all major ASEAN coil suppliers.
Packaging & Quality Assurance
Every LC-MR-PRO-1500 completes a 3-day factory acceptance test (FAT) including a continuous 48-hour production trial with quality sampling every 2 hours. All data is compiled into a FAT certificate. The complete line is disassembled into logical modules (decoiler, leveler, forming unit, flying shear, auto-stacker, conveyor) for containerized shipping. Each module receives VCI anti-corrosion treatment and multi-layer industrial stretch wrap, secured to custom-welded steel shipping cradles in two 40 ft high-cube containers.
Included with every machine: comprehensive toolkit with torque wrenches and alignment fixtures, 2-year critical spare parts inventory (rollers, blades, sensors, belts, PLC backup module, HMI spare screen), complete technical documentation in English, Bahasa Indonesia, and Vietnamese, USB drive with full setup and maintenance video library, and a spare parts catalog with ordering codes.
24-Month Comprehensive Warranty covering all mechanical and electrical components. Optional on-site installation supervision and operator training by a Lancai field engineer (10 working days, available for all ASEAN countries). 48-hour critical spare parts delivery to all ASEAN capitals.
