In modern civil and structural engineering, corrugated ducts play a vital role in post-tensioned concrete applications, especially in bridges, highways, and large-scale infrastructure projects. At Hechengyuan Machinery, we manufacture high-performance Corrugated Duct Forming Machines designed to meet the exacting standards of global construction professionals. If you are looking for a reliable and efficient way to produce galvanized or plastic corrugated ducts, our solution is engineered for you. What Is a Corrugated Duct Forming Machine? A corrugated duct forming machine is a specialized piece of equipment used to produce spiral or annular ducts with a corrugated surface. These ducts are commonly used as protective sheaths for post-tensioning tendons in concrete structures. The corrugations increase the bonding strength between the duct and concrete, ensuring better load transfer and durability. Hechengyuan’s forming machines are designed to produce ducts with high precision, excellent forming consistency, and stable performance—even under continuous operation. Key Features of Hechengyuan’s Corrugated Duct Forming Machine High Production Efficiency: Fully automatic feeding, forming, cutting, and coiling for faster turnaround. Versatile Duct Sizes: Compatible with a range of inner diameters, from 40mm to 130mm, suitable for different construction needs. Advanced Control System: Equipped with PLC and touch screen interface for easy operation and real-time monitoring. Durable Structure: Built with wear-resistant components for long-term stability and low maintenance. Customizable Output: Options for galvanized steel strip, stainless steel strip, or PE/PP plastic duct production. Whether you’re producing ducts for bridges, buildings, or tunnels, our machines provide the speed and accuracy required to keep your projects on schedule. Applications in Infrastructure Projects Corrugated ducts formed by our machines are widely used in: Post-Tensioned Bridges Highway and Railway Projects Hydraulic Power Stations Precast Concrete Beams Underground Pipe Tunnels Civil Engineering and High-rise Buildings These ducts ensure effective tendon protection, reduce construction risk, and improve the lifespan of concrete structures.
