The CDRG-45 bar threading machine, also known as a rebar threader or thread rolling machine, is essential for construction projects requiring high-strength rebar connections. This guide provides detailed product specifications, supplier information, and expert guidance for purchasing the CDRG-45 online.
The CDRG-45 is a heavy-duty machine designed to create precise threads on reinforcement bars (rebar) ranging from 14mm to 45mm in diameter . It uses a cold thread rolling process for one-time molding, stripping ribs and rolling threads simultaneously .
Key Applications:
Infrastructure projects (bridges, dams, high-rise buildings)
Reinforced concrete structures requiring high-strength connections
On-site construction for fast, reliable bar jointing
