We require a conveyor-based material handling system to integrate with existing rebar processing machinery. The solution must handle steel rods/pipes with length range 1200-12000mm and diameter 12-40mm.  

Key requirements:  
- Single conveyor line supplying 4 machine bays (cutting, cold forging, threading)  
- Buffer storage capability for continuous operation  
- Smooth material transfer and automated distribution  
- Compatibility with existing equipment  

Please provide:  
1. System design/layout with technical specifications (drive system, speed, load capacity, automation)  
2. Integration plan for current machinery  
3. Delivery timeline and commercial terms  

Vendors with experience in steel rebar handling systems are preferred. Customization options for precise operational needs are essential.
