Core Components of a Light Steel Framing Machine

A light steel framing machine — also widely known as an lgs machine — transforms steel coils into standard C, Z and U structural profiles through continuous cold roll forming. Built for high precision and stable operation, our lgs machines suit a broad range of construction applications:

Residential Construction: Roof trusses, wall frames and floor systems for buildings up to 6 stories high

Public Buildings: Heavy-load structural frames for schools, hospitals and stadiums, including MPA300-type systems

Commercial Complexes: Custom-made profiles for curved ceilings and partition wall assemblies

Industrial Warehouses: Heavy-gauge C-profiles (1.0-2.0 mm) for primary structural support

Emergency Prefab Housing: High-speed forming lines for rapid-deploy disaster-relief building frames

Key Machine Components

Uncoiler and Leveling Unit This station unwinds raw steel coils and relieves internal material stress. It keeps feed stock flat and consistent for stable production of your lgs steel framing components.

Punching and Notching Station Heavy-duty precision dies create 3.5 mm-20 mm holes for bolt connections, cable routing and assembly joints. Punching accuracy holds at ≤±0.5 mm. Combined hydraulic-servo drive delivers steady force for the complete lgs machines system.

Roll Forming Main Unit Fitted with Cr12 alloy rollers (HRC58-62), this section gradually shapes flat steel strips into C, U and Z profiles. The heavy-duty H-beam main frame maintains stable running speeds for your lgs framing roll forming machine during long production runs.

Hydraulic Cut–to–Length System Automatic shearing cuts finished profiles to exact lengths. Cutting accuracy reaches ±2.0 mm, ensuring uniform dimensions for all lgs steel framing parts.

PLC HMI Control System Siemens PLC paired with a touch-screen human-machine interface lets operators adjust line speed, punching cycles and cutting lengths. Full-automated operation reduces manual labour and improves overall consistency for your lgs machine system.

Full Production Workflow: Uncoil → Level → Punch → Roll Form → Shear → Automatic Stacking

Working Principle & Material Compatibility

Forming Process

Steel strip feeds continuously through the production line. After leveling and stress removal, sequential roller sets bend the material into target profile shapes. Punching operations happen simultaneously. Completed profiles are cut to required lengths and stacked automatically.

What Is a Purlin Roll Forming Machine

Roll forming is a continuous cold-forming process that flattens and bends steel coil into fixed cross-section profiles. Purlin profiles are secondary structural members widely used in steel building frames for roofs and wall girts. While fixed single-profile machines only output one style, interchangeable variants like our CZ purlin machine combine multiple profile capabilities on one forming frame. For a broader overview of our full equipment range, see our roll forming technology overview.

Types of Purlin Profiles: C, Z, CZ, U, and Sigma

In the steel industry, specific nomenclature is assigned to structural shapes to simplify drawings and engineering documentation:

• Optional punching, stacking, and cutting configurations.

Automatic-Change-Over VS Manual-Adjust Purlin Machine

Both machine versions process C-section, Z-section and U-section purlins within the size range 100–300 mm.

Key Insight: For factories running mixed C/Z orders, the automatic change-over model typically pays back its higher initial cost within 12–18 months through reduced changeover time and lower labor cost.

CZ Purlin Machine Models: CZ-300, CZ-350, CZ-400

Zheng Liming builds three standard CZ purlin roll forming machine models. All three share the same PLC-controlled automatic changeover system and 3–5 minute C-to-Z switching, but differ in profile range, material thickness capacity, main motor power, forming stations, and machine weight. Choosing the right CZ purlin machine model comes down to your largest profile size and heaviest steel thickness.

CZ-300 (Regular): Standard Range CZ Purlin Machine

The CZ-300 (Regular) is our most widely specified CZ purlin roll forming machine. It covers C purlin web heights from 100 mm to 300 mm and Z purlin web heights from 120 mm to 300 mm, with material thickness from 1.5 mm to 3.0 mm. It features 17 main forming stations + 1 ribbing station + 2 shaping stations, driven by a 30 kW Inovance servo motor, delivering 0–30 m/min output. The main shaft is Φ75 mm, side plate thickness 38 mm, and machine weight approximately 17.0 tons with a 11,900 × 2,000 × 2,000 mm footprint. This model suits steel structure fabricators running mixed C and Z orders in the 100–300 mm range — the most common specification in warehouse and light industrial construction. See full specifications on our CZ-300 CZ purlin machine.

CZ-350 (Heavy-Duty): Extended Range for Larger Spans

The CZ-350 (Heavy-Duty) extends both C and Z purlin capacity to 350 mm web height. Material thickness rises to 3.5 mm, driven by a larger 40 kW Inovance servo motor. It shares the same 17 main forming stations + 1 ribbing station + 2 shaping stations configuration as the CZ-300, with Φ75 mm main shaft and 38 mm side plates. Machine weight increases to approximately 20.0 tons with a 12,400 × 2,000 × 2,000 mm footprint. Specify the CZ-350 when your projects call for longer roof spans or heavier snow and wind loads, where 300 mm purlins no longer meet the structural calculation. See full specifications on our CZ-350 CZ purlin machine.

CZ-400 (Extra-Heavy): Heavy-Duty CZ Purlin Machine

The CZ-400 (Extra-Heavy) is the heavy-duty end of our CZ purlin machine range. C and Z purlin web heights reach 160–400 mm, flange width extends to 50–120 mm, and material thickness capacity goes up to 4.0 mm. It features 21 main forming stations + 1 ribbing station + 2 shaping stations, a 52 kW Inovance servo motor, a reinforced frame with 43 mm side plates, and a Φ95 mm main shaft. Output is 0–30 m/min. The machine weighs approximately 38.0 tons with a 17,500 × 2,600 × 2,100 mm footprint. This model is specified for heavy industrial buildings, large-span portal frames, and projects using Q345 or higher-grade steel. See full specifications on our our purlin machine series.

CZ-300 vs CZ-350 vs CZ-400: Which Model Fits Your Project

The table below compares the three CZ purlin machine models on the parameters that most often decide a purchase. All values are based on our standard factory configuration. If your profile drawings fall between two models, choose the larger one — an oversized CZ purlin machine runs your smaller profiles without difficulty, while an undersized machine cannot be upgraded later.

Two selection rules that save most buyers a costly mistake. First, match the model to your heaviest thickness, not your average — a CZ purlin machine running at its thickness limit wears rollers faster and produces looser tolerances. Second, confirm the Z purlin web height against your structural drawings before ordering; upgrading from CZ-300 to CZ-350 after delivery is not possible because the roller set and frame geometry differ.

CZ Purlin Production Line: Speed, Output and Line Layout

A complete CZ purlin production line runs from decoiler to finished bundle in six stages. Understanding the throughput of each stage tells you where a bottleneck will appear once you scale to two or three shifts.

At an average forming speed of 15 m/min with a 6 m purlin length, a CZ purlin machine produces roughly 150 pieces per hour — about 900 meters of finished purlin per shift. When running at the maximum 30 m/min, output roughly doubles to about 300 pieces per hour, provided the punching and stacking stages can keep pace. Adding a pneumatic auto stacker removes the single most labor-intensive step and typically pays back within 8–12 months on a two-shift operation.

Line layout matters more than most buyers expect. A CZ-400 configured with decoiler, pre-punching, forming, cutting, and auto stacker needs about 17.5 meters of floor length and 2.6 meters of width, plus forklift access at both ends. Confirm your bay dimensions before finalizing the order — relocating a CZ purlin production line after installation is expensive.

CZ Purlin Machine for Steel Structure Projects

CZ purlin machines serve any operation that converts steel coil into secondary structural framing. The six scenarios below cover the majority of our CZ purlin machine installations across 96 countries.

1. Steel Structure Warehouses and Logistics Centers

Warehouse roof and wall framing is the single largest application for CZ purlin machines. A typical 10,000 m² logistics building uses 300–500 tons of purlins in mixed C and Z configurations, which makes the automatic changeover of a CZ purlin machine far more economical than running two separate fixed-profile lines. For wall framing details, you can read our C purlin guide.

2. Pre-Engineered Buildings (PEB)

PEB manufacturers run high volumes of Z purlins for roof framing and C purlins for wall girts on the same order. A CZ purlin machine lets one line cover both without a second machine, second operator, or second floor footprint. You can learn roof load details in our Z purlin guide.

3. Cold Storage and Agricultural Buildings

Cold storage facilities require closely spaced purlins to carry insulation panels and snow loads. CZ-350 and CZ-400 models are commonly specified here because the heavier Z purlin sections handle the additional dead load without increasing purlin count.

4. Roofing and Cladding Contractors

Contractors who both manufacture and install benefit from producing purlins to exact site lengths, eliminating cut waste and transport cost. A CZ purlin machine running on site reduces lead time from days to hours.

5. Steel Service Centers and Distributors

Service centers producing purlins to order need fast changeover between profile sizes. The PLC one-touch changeover on our CZ purlin machine completes a C-to-Z switch in 3–5 minutes, which makes short-run and made-to-order production viable.

6. Export-Oriented Purlin Manufacturers

Suppliers exporting to markets with different structural codes need a CZ purlin machine that covers the full C100–C400 and Z120–Z400 envelope in one unit, since re-tooling for each destination market is impractical.

CZ-300 (Regular) Key Technical Specifications

Key Machine Features

• Full-automatic production workflow from metal-coil feeding, leveling, punching, forming to cutting.
• PLC-powered stepless profile switching between C-type and Z-type sections.
• One-touch fast parameter adjustment for different profile sizes.
• High-precision forming with consistent hole positions and cutting length.
• Heavy welded main frame for stable long-time continuous running.
• Emergency stop protection and fault alarm on HMI.

CZ Purlin Roll Forming Machine Price and Factory Quote

Buyers searching for a CZ purlin roll forming machine price usually find ranges that are too wide to be useful. The reason is that a CZ purlin machine is configured, not catalogued — five variables move the price more than anything else.

Because of these variables we quote factory-direct after reviewing your profile drawings, target output, and material spec — not from a published list. Send us three things and you will receive a complete technical proposal with price within 24 hours: your purlin profile drawing (C or Z section with dimensions), the steel grade and thickness range, and your required output in meters per shift.

As a reference point, buyers comparing CZ purlin roll forming machine prices across suppliers should ask each one the same five questions: what is the roller material and hardness, how many forming stations, what is the cutting tolerance, what is included in the warranty, and what is the spare parts lead time. Suppliers who answer all five specifically are usually quoting a real configuration rather than a placeholder number. If you are selecting a supplier, check our guide: How to choose a CZ purlin machine supplier.

How to Choose a CZ Purlin Machine Supplier

Many buyers focus only on price, but stable after-sales and accurate forming quality decide your long-term production cost. Reliable CZ purlin machine suppliers should provide clear technical drawings, roller lifetime guarantee, on-site installation guidance and spare parts support.

Check the factory’s export history, case references in your region, and whether they test each CZ purlin machine before shipment. Avoid vendors who cannot confirm profile tolerance and roller material specification in writing.

CZ Purlin Machine Maintenance and After-Sales

Routine maintenance keeps your CZ purlin production line running at stable speed and reduces unexpected downtime. The core maintenance items include roller surface cleaning, gearbox oil replacement, guide rail lubrication, and hydraulic oil inspection for flying shear.

Our after-sales package includes operation manual, remote video guidance, and overseas engineer service for large projects. Spare rollers, cutting blades and seals can be shipped separately when you place a reorder.

Frequently Asked Questions About Purlin Machine

Q1: What is the difference between C purlin and Z purlin?

A1: C purlins are open C-channel sections, mainly used for wall girts and simple connections on one side. Z purlins are overlapping Z sections, designed for long-span roof structures with lap splicing. A CZ purlin machine covers both on one interchangeable forming line.

Q2: What is a CZ purlin roll forming machine?

A2: A CZ purlin roll forming machine is an adjustable cold forming line that switches between C purlin and Z purlin profiles automatically for mixed steel structure orders.

Q3: Can your purlin machine switch between C and Z profiles automatically?

A3: Yes. Our automatic CZ purlin machine completes a C-to-Z changeover in 3–5 minutes through PLC one-touch parameter recall, with no manual bushing replacement. Manual-adjust models require 20–40 minutes and are recommended only for fixed-specification, high-volume production.

Q4: What materials can your purlin machine process?

A4: Cold-rolled steel and galvanized steel, Q235 and Q345 high-strength steel, thickness matching your selected CZ model (1.5–4.0 mm depending on model).

Q5: What is the difference between CZ-300, CZ-350 and CZ-400?

A5: The three CZ purlin machine models differ mainly in profile capacity, material thickness, motor power, and machine weight. CZ-300 (Regular) covers C100–300 mm / Z120–300 mm at 1.5–3.0 mm thickness, with 17 main forming stations and a 30 kW servo motor. CZ-350 (Heavy-Duty) extends the range to C100–350 mm / Z120–350 mm at 2.0–3.5 mm thickness, with 17 main forming stations and a 40 kW servo motor. CZ-400 (Extra-Heavy) handles C160–400 mm / Z160–400 mm at 2.0–4.0 mm thickness, with 21 main forming stations and a 52 kW servo motor. All three use PLC one-touch automatic changeover. Select based on your largest Z profile and heaviest steel thickness.

Q6: What is the output capacity of a CZ purlin production line?

A6: At an average forming speed of 15 m/min with 6-meter purlin lengths, a CZ purlin machine produces roughly 150 pieces or 900 meters per 8-hour shift. At the maximum 30 m/min, output roughly doubles to about 300 pieces per hour, provided downstream punching and stacking can keep pace. Adding a pneumatic auto stacker removes the manual stacking step and typically allows one operator to run the line.

Q7: Can the machine punch holes automatically?

A7: Yes, hydraulic pre-punching unit is standard on all three models, with customizable hole pitch and hole pattern for purlin connection. Standard hole sizes are 14×22 mm for bottom single hole, bottom double hole, and flange double hole configurations.

Q8: Can one CZ purlin machine produce Sigma and U profiles as well?

A8: Our 4-in-1 C/C+/Z/Sigma configuration supports all four profile families on a single line. Standard CZ models cover C, Z, and U. If your order mix includes Sigma sections, specify the 4-in-1 configuration when requesting a quotation, as the roller set differs.

Q9: What after-sales support does Zheng Liming provide for overseas customers?

A9: Standard warranty is 12 months from machine arrival, excluding consumable parts such as rollers, cutting blades and seals. We can send professional engineers to your workshop for machine installation, commissioning and operator training for large orders. Spare rollers, cutting blades and seals can be shipped separately when you place a reorder.

Q10: What is your typical lead time for a CZ purlin machine?

A10: Standard lead time is 90 working days for CZ-300 and CZ-350, and120 working days for the heavy-duty CZ-400, from deposit receipt and drawing confirmation, excluding shipping time. Custom roller sets, 4-in-1 configurations or special voltage requirements may require additional time, confirmed at order stage.

In construction, C/Z purlins are key structural supports. The performance of their production equipment directly affects project quality and costs. This article introduces an innovative cold roll forming machine designed for the strict demands of Indian and Turkish markets, including local climates and building standards.

1. Core Tech: Fast Mode Switching & Precise Production

The machine uses patented servo-driven coaxial sliding sleeve technology. It can switch between C-type and Z-type purlin production in 3 minutes via PLC control, no manual disassembly or roller calibration needed. This suits small-batch, multi-type production well, boosting flexibility.

It handles C80-300 and Z120-300 sizes, meeting India’s IS 2062 and Turkey’s TS 648. It processes galvanized steel (zinc≥275g/m²) and high-strength steel (G550) stably, with 15% better material efficiency to cut costs. The Cr12 cold work die steel rollers (HRC58-62 after heat treatment) work reliably under tough conditions, paired with hard-chrome-plated bushings.

On the workshop floor, the atmosphere was focused and intense. Participants, equipped with protective gear and welding torches, precisely controlled the arc and angle. The judging panel meticulously evaluated the quality of each weld and the adherence to operational procedures to ensure fairness and impartiality—a microcosm of our daily quality control standards.

2. Structural Design: Built for Harsh Environmentsrizes, respectively.

For India’s high humidity (rainfall≥2000mm/year) and Turkey’s coastal salt spray (chloride≥0.5mg/m³),the machine has an optimized design. Its H-beam frame (flatness±0.5mm) and modular wall panels (28-43mm thick) ensure rigidity.

It uses a 3-layer anti-corrosion coating: shot blasting, epoxy primer, and polyurethane topcoat. This blocks moisture and corrosion.

3. Key Component Upgrades

(1) Roller System

The Cr12 steel rollers (HRC58-62) last over 1.5 million cycles, 40% longer than standard alloy steel. Precision grinding ensures consistent purlin quality (±0.5mm tolerance) and less maintenance.

(2) Reinforced Shafts

45# solid shafts (tensile strength 600MPa) get hard-chrome plating (≥0.05mm). This improves fatigue and corrosion resistance for long-term heavy-duty use.

4. Smart Control Systemr Skills to Equipment Reliability

The PLC servo system includes Turkish/Hindi interfaces for easy use. It forms purlins at 30m/min with±1.0mm cutting accuracy. A±0.1mm feeding system reduces waste, hitting 98% material utilization. Compared to hot-rolling, it uses 40% less energy, with a scrap recycling system.

Technical Specifications at a Glance

5. Practical Benefits

Fast mode switching cuts equipment costs. Modular rollers reduce maintenance time by 30%. The energy-saving design lowers bills. It makes purlins for industrial plants, greenhouses, and warehouses (span ≤ 20m), meeting local standards.

This machine balances precision, durability, and cost-efficiency, solving real-world purlin production challenges in India and Turkey.
