product description

1. Product Overview

This fully automatic CZ purlin roll forming machine is an integrated multi-functional cold bending equipment specially developed for manufacturing C purlins and Z purlins. It realizes fast switching between C-shaped and Z-shaped steel without manual disassembly of rollers, greatly improving production efficiency for steel structure factories. Equipped with hydraulic punching, automatic cutting, PLC intelligent control and continuous forming system, the machine processes galvanized steel coils, cold rolled steel strips into standard CZ purlins widely used in warehouse, workshop, stadium, solar bracket, prefab steel building roof and wall support components.

2. Core Advantages

1. Fast C/Z Quick Switch Design No need to replace forming rollers; just adjust the side guide and hydraulic spacing through the touch screen to convert C purlin to Z purlin within 3-8 minutes, saving labor and downtime compared with split single C or single Z machines.
2. High Precision Forming & Hydraulic Punching Integrated hydraulic punching unit pre-punches bolt holes on the web and flanges in one pass. The formed purlin features smooth surface, consistent dimension, right-angle bending, no deformation, fully compliant with national steel structure standards.
3. Full Automatic PLC Control System Adopts industrial touch screen + PLC intelligent controller. Operators can set purlin height, flange width, thickness, hole spacing and cutting length on screen. The machine completes uncoiling, leveling, forming, punching, length measuring and fixed-length cutting automatically.
4. Heavy-Duty & Durable Structure Main machine base adopts thickened integral welded steel plate, solid roller support frames. Forming rollers are forged from high-grade Cr12MoV alloy steel with quenching treatment, wear-resistant and long service life for long-term mass production.
5. Wide Raw Material Compatibility Supports raw material thickness from 1.2mm to 3.5mm, suitable for galvanized steel strip, cold rolled carbon steel, pre-painted steel coil; adjustable purlin specification covers 80-300mm height, meeting different construction load requirements.
6. Low Maintenance & Stable Operation Equipped with independent hydraulic station and circulating lubrication system, low noise during running, stable transmission, reducing later maintenance cost and failure rate.

4. Application of Finished CZ Purlin

The C purlin and Z purlin produced by this CZ purlin roll forming machine are core secondary structural parts of steel construction projects:

• Industrial factory workshops, logistics warehouses
• Prefabricated steel frame buildings
• Large stadiums, exhibition halls, shopping malls
• Solar photovoltaic support systems
• Agricultural greenhouses, livestock farms
• Roof and wall purlin support for low-rise villas

Compared with traditional channel steel, CZ purlins have lighter weight, higher bending resistance, lower transportation cost, and convenient installation with bolt connection.

5. Production Process Flow

Steel coil uncoiling → material leveling → servo feeding positioning → hydraulic hole punching → continuous cold roll forming → automatic C/Z shape switching → length tracking measurement → hydraulic fixed-length cutting → finished purlin output & stacking
