In the logic of steel structure construction, if the main steel frame is the skeleton, then C-shaped and Z-shaped purlins are the "meridians" running through it, bearing the entire load of the roof and walls. Their specifications vary greatly, and their usage is enormous, directly affecting project progress and cost. Traditional production methods rely on two separate machines, one for C-shaped purlins and one for Z-shaped purlins, which require a large area, high investment, and are time-consuming and labor-intensive when changing shapes. The AFQ fully automatic CZ-shaped steel forming machine was created to solve this problem: with its integrated "one machine, two shapes" design, it combines the production of C-shaped and Z-shaped purlins onto a single production line, making flexible manufacturing and economies of scale no longer mutually exclusive.

Features: A Quadruple Leap Forward in Speed, Accuracy, Stability, and Economy

1. One-Click Quick Changeover: C/Z Switching Completed in 0–20 Minutes

This is the core competitiveness of the AFQ CZ integrated machine. Through its ingenious roller structure design and one-click operation via touchscreen, the machine can complete the contour switching between C-type and Z-type purlins within 0–20 minutes, without replacing the entire forming roller assembly or performing large-scale mechanical disassembly. Simultaneously, the purlin width, height, and even thickness can be automatically adjusted within a set range. One machine can handle orders of multiple specifications, reducing "changeover downtime" from hours of agony to minutes of ease.

2. Intelligent PLC Control, Reducing Dependence on Experienced Operators

The entire line is equipped with a PLC intelligent control system and a touchscreen human-machine interface, integrating feeding, forming, punching, cutting, counting, and parameter storage onto a unified platform. Operators can complete specification settings and changeover instructions directly on the screen, reducing over-reliance on manual experience and making production rhythm more controllable and repeatable.

3. Heavy-duty frame and precision rollers ensure consistent precision over the long term.

The equipment uses a heavy-duty frame welded from high-strength steel plates. Through stress relief and precision machining, it effectively suppresses vibration during continuous production, ensuring long-term consistency of product dimensions. The forming rollers are made of GCr15 bearing steel, CNC machined, heat-treated, and precision ground, combining wear resistance and forming accuracy, significantly extending maintenance cycles and equipment lifespan.

4. Online punching and flying saw cutting, one-time forming without secondary processing

The hydraulic punching system can punch connecting holes at any position on the purlin web and flange, simultaneously with the forming process, eliminating the need for subsequent drilling. Fixed-length flying saw cutting ensures a clean cut and precise length, allowing finished products to immediately enter the assembly stage, truly achieving "one-time forming, ready to use."

5. Unlimited length and material-saving design, improving material utilization

Within the equipment's capabilities, the AFQ CZ machine supports the "unlimited length" production concept, allowing flexible setting of purlin length according to order requirements. This reduces material waste from fixed-length cutting, helping users save material costs from the source.

Application Scenarios: Wherever there are steel structures, there is a use for C/Z purlins.

•  Steel Structure Factories and Warehousing Logistics

This is the largest user area for C/Z purlins. The equipment can continuously produce Z-shaped roof purlins in the morning and switch to C-shaped wall purlins with a single click in the afternoon. One production line can meet the purlin needs of the entire factory envelope system, quickly responding to orders with different spans and load requirements.

•  Precast Buildings and Integrated Housing

Precast projects have complex specifications, a high customization rate, and tight delivery windows. The rapid changeover capability of the CZ integrated machine perfectly matches the production characteristics of "small batches, multiple specifications, and short lead times," making it an ideal choice for precast building component factories.

•  Photovoltaic Supports and Agricultural Greenhouses

Lightweight and high-strength C-shaped steel is an important material for photovoltaic solar panel supports and modern greenhouse columns. The equipment's online punching function can complete the processing of support connection holes simultaneously with forming, significantly improving the on-site installation efficiency of photovoltaic projects.

AFQ Fully Automatic CZ Steel Forming Machine:

Q1: What is the AFQ Fully Automatic CZ Steel Forming Machine?

A: The Fully Automatic CZ Steel Forming Machine is an integrated cold bending forming equipment for steel structure purlin production. It integrates uncoiling, leveling, feeding, forming, punching, fixed-length cutting, and automatic unloading and stacking into a single production line. Its core advantage is "one machine, two types"—the same machine can produce both C-type and Z-type purlins.

Q2: Is the C-type and Z-type switching really fast?

A: The CZ integrated machine, through its roller structure design and one-button operation via a touchscreen, can complete the C/Z profile switching within approximately 10–15 minutes, without requiring the replacement of the entire set of rollers or large-scale mechanical disassembly and assembly. It is particularly user-friendly for orders with multiple specifications, small batches, and short lead times.

Q3: What specifications can one machine cover?

A: The equipment can adjust the purlin width, height, and thickness within a set range and supports the storage of multiple specification parameters. The specific processing range needs to be confirmed based on material strength, plate thickness, and cross-sectional requirements. AFQ can be matched and configured according to the purlin specifications commonly used by users.

Q4: What materials can it process?

A: It can reliably process hot-dip galvanized coils, Q235/Q355 carbon steel coils, weathering steel coils, and zinc-aluminum-magnesium coils, etc. Actual material compatibility needs to be selected and confirmed in conjunction with plate thickness, yield strength, and forming cross-section.

Q5: What are the advantages of online punching and flying saw cutting?

A: Hydraulic punching can simultaneously punch connecting holes at set positions on the web and flange, eliminating the need for subsequent drilling; fixed-length flying saw cutting ensures a smooth cut and precise length, allowing finished products to enter the assembly stage immediately after production, reducing secondary processing and transportation costs.

The fully automatic CZ profile steel forming machine replaces the redundant investment of two machines with the integrated intelligence of one machine; it responds to the increasingly fragmented and flexible production reality of the steel structure market with minute-level changeover freedom. When the switching between C and Z is no longer a bottleneck, purlin manufacturing truly moves from "being able to produce" to "knowing how to produce".
