Ultimate CZ Purlin Roll Forming Machine: CZ350*3.5 model

In the fast-paced world of steel structure manufacturing, efficiency is not just an advantage—it is a necessity. Whether you are constructing massive industrial warehouses, agricultural storage facilities, or commercial high-rises, the backbone of your structural integrity lies in the quality of your purlins. And the CZ Purlin Roll Forming Machine is the heart of this production process stands.
Today, we are diving deep into a specific powerhouse in this category: the CZ350*3.5 CZ Purlin Roll Forming Machine. With its strong structure engineering, servo motor driven precision, this purlin roll forming machine is redefining product what it means to manufacture C and Z purlins. Below are the detailed specifications for Beenew brand CZ350 purlin roll forming machines:

What is a CZ Purlin Roll Forming Machine?

It is better to understand CZ Purlin Roll Forming Machine’s role before we learn the specifications of CZ350*3.5 model. Unlike traditional single-purpose machines that produce either C-shaped or Z-shaped purlins, a CZ purlin machine is a dual-purpose system. Roll forming machine manufacturers will make purlin machines can be switched between profile types without changing the roll sets.
For different load bearing capacities on construction projects, different size purlin sizes and material thickness are needed often. So our CZ350 purlin roll forming machine ‘s ability to handle the entire range of cold-formed steel sections is indicated by the “CZ” designation, it can roll form C100-350/Z140-350 purlins and varies thickness at 1.8-3.5mm, which offers a smooth transition between profiles to save downtime and increase output.

Technical Breakdown for CZ350*3.5

The CZ350*3.5 Purlin Roll Forming Machine is made for heavy-duty performance. It is suitable for Q235 and Q345 yield strength steel coil. Let’s look at the key parameters of this model purlin machines from the competition.

1.Profile Dimensions

Purlin Width: C purlin from 100mm to 350mm; Z purlin ranges from 140mm to 350mm.
Purlin Height: 50- 100mm for C and Z purlins shapes.
Purlin Lip: Lip height ranges from 10mm to 25mm.
Feeding Width: This cz purlin roll forming machine accepts steel strips ranging from 199mm to 579mm, depends actual engineer needed purlin sizes.

2.Suitable Material Thickness

The construction industry often demands high tensile strength. This cz purlin roll forming machine is designed for:·
Q235 Steel: 1.8mm to 3.5mm·
Q345 Steel:  1.8mm to 3.0mm

Structural Integrity and High Quality Drive System Ensures Durability

The durability of a CZ Purlin Roll Forming Machine is determined by its frame and drive system. So this CZ350*3.5 roll forming equipment is constructed to withstand the rigorous demands of continuous industrial operation.
Heavy-Duty Frame Construction
Frame Wall Thickness: It is 30mm or even more thicker, the stronger frame walls improve cz purlin machine line’s stability more, and minimize vibration during high-speed production.

Machine Base: The base is made by H400 steel beams. This heavy-duty base ensures the machine remains anchored and level, it is good for preventing torsional flex and avoiding inaccuracies on final product.

Strong Transmission and Rollers

Roller Materials: The cz purlin roll forming machine chooses two types of materials: C12 and GCr15. Known for its high hardness and wear resistance, the flat wheels are made from GCr15 bearing steel. We use Cr12 die steel for inclined wheels due to consider Cr12 die mateiral’s excellent toughness for forming complex bends.
Roller Diameter:  φ90/75mm, made from 40Cr steel.
Leveling Unit: The leveling shafts are solid and diameter is φ105mm, total 7 shafts for leveling.

 

 

High-Quality Servo Drive

Main Motor: 37.0KW Servo Motor

Speed Regulation: Servo drive speed regulation, the CZ350*3.5 purlin machine achieves precise control over the forming speed. It is also good for smooth acceleration and deceleration, reducing mechanical stress. With servo motor driving, the roll forming speed can be more fast than common motor driving.

 

 

Fast Forming Speed

The CZ350*3.5 Purlin Roll Forming Machine’s maximum forming speed is 30m/min (without punching & cutting). This high-speed capability ensures that you can fulfill large orders quickly, maintaining a competitive edge in the market.

Auto Size Change

This is the auto size change purlin roll forming machine,  machine adopts 0.25kw and 0.55kw servo motor for size changing. All the web width, flange width, lip width can be set on touch screen and auto change then reducing downtime and labor costs well.

 

 

Hydraulic Punching and Cutting Systems

The CZ350 purlin machine is equipped with 4 punching groups:

3 groups for hole punching: hole sizes and shapes can be customized made for buyers.

Front Punching & Cutting:  3 punches for hole punching and one set front hydraulic flat cutting for cutting material head and tail without waste.

Post Cutting: The hydraulic system is driven by one 11KW motor, ensures a clean, burr-free cut across the web of the purlin, regardless of the material thickness.

 

 

D2 Mold Cutting Blades

The cutting bladesis dade from Cr12 MoV, they are subjected to heat treatment and wire cutting according to the dimensions we need.

Heat treatment is for ensuring the blades’ hardness and wear resistance, it can extend cutting blades working life.

Smart PLC Control System

A machine is only as smart as its control system. This  CZ350*3.5 purlin roll forming machine  is equipped with  smart PLC control system.

 

 

Intuitive Touch Screen Operation Interface

This sery purlin amchine matches with 7 inches touch screen as the primary human-machine interface. The operation mode combines switches, buttons, relays, and the touchscreen, offering flexibility for operators of all skill levels.

Advanced Functionality
USB Data Import: For improving producing speed, the control system has USB data import function for importing product task drawing, too. Operators can save complex production schedules (with varying lengths, sizes, and quantities) onto a USB drive and upload them directly to the sysytem This reduces human error in data entry.
Photoelectric Encoder: There is photoelectric encoder for counting. This precision guarantees that each purlin cut is exactly what the client specified, ensuring accurate measurements every time.

Multi-Stage Treatment

Machine Frame and Wall Panel Painting: After fabrication, the frames are painted and baked. This process yields a tough, long-lasting finish, impervious to chipping and corrosion.

Component Finishing: Internal parts like shafts, gears, and rollers receive treatment via chrome plating, galvanizing, or blackening. These methods create a protective barrier against rust and wear, allowing the machine to retain its accuracy and aesthetic appeal for years, even in challenging factory conditions with humidity and dust.

 

Unified Assembly

Following surface treatment, all components are brought together in a controlled environment. This “unified assembly” method guarantees a precise fit for each part. The result? Quicker installation for the user and a machine that’s ready to work, right out of the box, without any hitches.
