Introduction

Shuangli pre-stressed concrete purlin machine is an extruding machine specially for making concrete purlins, greenhouse purlins, roof support purlins, vine trellis posts and fence small columns. Adopting long-line prestressed production technology, it shapes concrete components in one pass. Finished purlins feature high density, smooth surface and stable strength. Widely used for greenhouses, farm sheds, breeding houses, fruit trellises, rural buildings and precast wall projects. It can work together with tension machine, batching plant and cutting machine to form a full production line.

Key Advantages

✅ Extrusion molding ensures high compaction, strong bending resistance and low cracking rate

✅ Multi-purpose: change moulds to produce purlins, small posts and lintels of different sizes

✅ Easy operation, low labor cost, ideal for medium & small precast factories

✅ Heavy welded frame + wear-resistant alloy forming parts, long service life & low failure

✅ Portable design, works while moving on precast casting beds

✅ Prestressed long-line process, finished length customizable by cutting

✅ Good compatibility, match with Shuangli batching machine, hollow core slab machine, cutter
