You can also check our purlin machine product page for detailed configuration options and factory pricing.

What Is a Z Purlin Roll Forming Machine?

A Z purlin roll forming machine is a continuous cold-bending purlin making machine that produces Z-shaped steel purlins from coiled raw material. Unlike symmetrical C-shaped profiles, Z purlins feature offset overlapping flanges that allow nested splicing, making them the preferred framing component for large-span industrial warehouses, factories and commercial steel buildings.

If you also produce C profiles, see our C purlin roll forming machine guide for a full comparison.

A finished Z purlin typically includes:

A vertical web plate
Two offset horizontal flanges (opposite-direction Z geometry)
Stiffened lips for enhanced load-bearing capacity
Pre-punched mounting holes for fast on-site assembly

Standard Z purlin forming machine configurations are available as automatic adjustable systems. In industrial sourcing, many buyers also refer to this equipment simply as a Z purlin machine.

What Does a Z Purlin Making Machine Produce?

A Z purlin making machine manufactures Z-shaped steel sections used across a wide range of structural applications:

Main roof purlins for large-span industrial and commercial buildings
Secondary framing for warehouses, workshops and exhibition centers
Support members for agricultural steel structures and grain silos
Wall girts for heavy-duty exterior cladding systems
Prefabricated steel building component manufacturing

For solar mounting profiles, see our solar mounting roll forming machine.

Compatible materials include cold-rolled steel coil and galvanized steel coil with yield strength of 235 MPa or 345 MPa. Standard processing thickness ranges from 1.5 mm to 3.0 mm depending on the machine model.

Note: The purlin machine is the production equipment; the Z purlin is the finished profile. When sourcing equipment for high-volume production, confirming your profile drawing and material thickness first will help you get the most accurate quotation.

How Does a Z Purlin Roll Forming Machine Work?

Standard Z purlin lines use a pre-punching and post-cutting workflow for maximum profile accuracy and clean edge finish. The process follows six sequential core stages:

1. Coil Decoiling

The raw steel coil is loaded onto a decoiler and unwound at controlled tension to feed the forming line steadily. Manual cantilever decoilers and hydraulic expansion decoilers are available to match different automation levels.

2. Pre-Leveling & Guided Feeding

The strip passes through a 7-roller leveling unit (4-over-3 arrangement, Φ95 mm leveling rollers) to remove coil set and surface bow, then enters the processing section with precise edge alignment.

3. Hydraulic Pre-Punching

Before forming, hydraulic punching stations punch mounting holes into the flat strip at pre-set intervals. Standard hole configurations include:

Bottom double holes – Punching Unit 1: 14×22 mm
Bottom single hole – Punching Unit 2: 14×22 mm
Side flange double holes – Punching Unit 3: 14×22 mm
Punch cylinder bore: Φ110 mm

This ensures accurate hole positioning and avoids profile deformation after forming.

4. Progressive Roll Forming

The strip travels through paired forming stations. Each station bends the material a small increment until the full Z cross-section is achieved. Gradual forming ensures uniform stress distribution and accurate flange geometry.

5. Hydraulic Post-Cutting

After full profile forming, a universal hydraulic shear with Cr12MoV heat-treated blades cuts the Z purlin to the target length. Cutting tolerance is ±1 mm. A slug breaker is included for high-volume production.

6. Finished Product Output

Cut Z purlins exit onto a 6-meter unpowered run-out rack (3 m × 2 sections) for collection, packaging and transport.

This continuous workflow is why a Z purlin forming machine delivers much higher output and dimensional consistency than manual press-brake forming methods.

What Is a C Purlin Roll Forming Machine?

A C purlin roll forming machine is a continuous coldbending production line built to produce C-shaped steel purlins from raw steel coils. Unlike press brakes that bend one piece at a time, this line feeds steel strip through multiple forming stations and gradually bends metal into target C-profiles without heavy internal stress.

A finished C purlin normally includes a flat vertical web, two horizontal flanges and reinforced lips at flange ends for better load-bearing performance. It can also come with pre-drilled mounting holes for fast site installation. Our pre-punch type C purlin roll forming machine makes holes on flat steel strip before roll forming, so you won’t run into hole shifting or profile twisting after shaping. We can customize web height, flange width, lip size and processing thickness to fit your project drawings. Many buyers simply call this unit an automatic C purlin machine in daily communication.

What Products Can a C Purlin Roll Forming Machine Make?

Our automatic C purlin roll forming machine outputs C-section steel parts widely used across modern steel construction:
-Roof purlins for metal building systems
-Wall girts for exterior wall cladding
-Secondary structural frames for industrial plants
-Support members for warehouses and workshops
-Components for pre-engineered prefab buildings

Supported raw materials cover galvanized steel, pre-painted steel, Q235, Q345 and S355 steel. Our heavy-duty automatic C purlin machine can handle 550 MPa high-strength steel. Usable material thickness ranges from 1.5 mm to 4.0 mm based on machine grade. Both standard and custom C purlin profiles are available for commercial and industrial jobs.

How Does an Automatic PrePunch C Purlin Roll Forming Machine Work?

Our standard automatic prepunch C purlin roll forming machine runs through 6 clear steps. It strictly follows the workflow: leveling → punching → roll forming, to get smoothlyshaped profiles with stable dimensions.

1. Coil Uncoiling

You load steel coils onto the uncoiler (uncoiler is optional; you may pick non-power cantilever type or hydraulic expansion type). The unit releases steel strip at stable tension to feed the whole line and avoid unstable feeding hurting finished quality.

2. PreLeveling & Guided Feeding

Steel strip passes our 7-roll leveling unit (4-upper, 3-lower, Φ95 mm leveling rollers) to remove coil camber and surface bending. After flattening, the strip goes into guide assemblies for precise edge alignment, getting ready for punching and forming work.

3. Hydraulic PrePunching (Standard Feature)

All punching work happens on flat steel before shaping. If you need mounting holes on purlins, the hydraulic punching station stamps preset hole patterns onto flat strips. Available hole types: single bottom hole, double bottom holes, double flange holes, standard hole size 14×22 mm. Punching on flat metal effectively prevents hole offset and profile distortion after cold bending. Matching hydraulic front shear uses Cr12MoV tool steel cutters to trim coil head & tail, suitable for steel strips longer than 2.5 m.

4. Progressive Roll Forming

Leveled and pre-punched steel strip moves through groups of forming rollers. Each roller group completes a small bending angle until the complete C-shape comes out. Forming rollers adopt Cr12 tool steel rollers (Mark: Cr12 hardness equivalent to D3). These rollers deliver high hardness and great wear-resistance for long-term stable forming performance. Light / medium / heavyduty units apply different formingstation counts for regular or thick high-strength steel.

5. Precision Shearing to Length

When profiles reach your target length, the universal hydraulic shear with Cr12MoV cutters cuts steel to size. Cutting tolerance can reach ±1 mm. High-end configurations work with encoders and PLC intelligent control to meet strict precision requirements from construction projects.

6. FinishedPart Discharge

Finished C purlins move onto nonpower runout tables for collection and packaging, ready for delivery to construction sites.

Core Components of Automatic PrePunch C Purlin Production Line

Our full automatic pre-punch C purlin roll forming line includes standard parts plus optional add-ons, to realize full-auto workflow from coil feeding to finished-part output.

Standard configuration: Hydraulic front shear unit, 7-roll leveling & feeding assembly, hydraulic pre-punch station, forming main host, universal rear shear, hydraulic power pack, integrated electric control cabinet, non-power run-out table, insert-type safety guards, original tool set and wear spares. Electric system includes Siemens touch-screen, Omron encoder and wireless remote controller. Operators can adjust web / flange width, punching quantity and cutting length directly on HMI.

Optional configuration: 5ton nonpower cantilever uncoiler; 5ton hydraulic expansion uncoiler.

Component quality directly decides machine stability, profile accuracy, running speed and service life. When you compare different supplier quotations, pay close attention to PLC brand, hydraulic system, drive motors, bearings and shear blade specifications.

6. Reliable Structural Performance

Mass-produced C purlins own stable load-bearing capacity. Our heavy-duty grade works well for high-strength thick steel to boost overall building rigidity and construction safety.

How To Pick The Right Automatic C Purlin Roll Forming Machine

1. Confirm WebHeight & Flange Size

Match machine grade with your regular job sizes. Pick light-duty C80-300 for web height 40-80 mm; choose medium-duty or heavy-duty for web height 45-100 mm. For special non-standard profiles, go for custom-built solutions.

2. Match Plate Thickness & Steel Yield Strength

-For plate ≤3.0 mm with Q235 / Q345 steel: light-duty or medium-duty models work fine.

-For plate 3-4.0 mm or 550 MPa high-strength steel: you must select heavy-duty C100-300. Thick material demands stronger forming stations, larger shafts, thicker side plates and higher-power drive. If your requirement exceeds standard-model limits, take custom-built lines into consideration.

3. Provide Your Exact Profile Drawings

Mark clear dimensions for web, flange, lip, hole size & hole spacing. This helps our team work out accurate machine proposals and avoid custom-made deviations. Think over whether you need pre-punch function: prepunch gives better hole precision than post-forming punching.

4. Clarify Your Punching Requirements

This automatic series comes with built-in hydraulic prepunch. It supports single bottom hole, double bottom holes and double flange holes, standard hole size 14×22 mm. Punching on flat steel ensures neat hole openings without profile warping. Special non-standard hole patterns can be custom-engineered.

5. Set Proper Production Speed

Light-duty & medium-duty max speed:30 m/min. For heavy-duty thick-gauge jobs, 25 m/min is recommended. Don’t blindly chase top speed when you process thick high-strength steel.

6. Pay Attention To Cutting-Tolerance Requirement

Our universal shear delivers ±1 mm cutting tolerance, better than common ±2 mm regular machines. It fits construction projects with strict length-precision demands.

7. Understand Automation Level

This is an automatic pre-punch C purlin production line. Standard package includes Siemens touch-screen, Omron encoder and wireless remote controller for easy parameter setup for size, punching and cutting length. If you need one-touch switching between C-profile and Z-profile, look at our CZ purlin roll forming machine.

8. Plan Your Uncoiler Option

Uncoiler is not included in standard scope. Choose low-cost non-power cantilever uncoiler for simple jobs; select hydraulic expansion uncoiler for heavy steel coils that need tight inner-hole gripping.

9. Evaluate Supplier Experience & After-Sales Service

Work with manufacturers with solid cold-roll-forming experience, who can offer overseas installation, operator training and full spare-parts supply. They also need capability for custom-built roll-forming lines for special drawings.

10. Balance Budget & Return On Investment

Balance upfront investment, output improvement, labor saving, raw-material reduction and long-term maintenance expense to get your most cost-effective setup. For custom-built projects, we evaluate your drawings first then offer proposal & quotation.
