If you produce steel buildings, you know what it costs to buy purlins from third parties or to keep two separate lines, one for C sections and one for Z sections. A C/Z purlin roll forming machine solves both problems on the same line. LAZIRON CZ cold-forms C and Z steel purlins from 1.5–3.0 mm strip, black or galvanized, switching between profiles without replacing rollers, under PLC control. Profile width and height are adjusted automatically, and production speed reaches 25 m/min, depending on punching frequency.
In the flow of a steel structure plant, the machine works in parallel with the beam line: while the building's main frames are being welded, the roof and wall purlins are roll formed, punched and cut to length directly from the strip. It replaces buying purlins from suppliers and the long roller changes on single-profile machines, which stop production for every new order. See also the other auxiliary equipment for steel structure plants.
• C/Z changeover without changing rollers: switching between C and Z profiles is done under PLC control, without dismantling the rollers. Downtime between orders drops, and the same line covers both purlin types.
• Automatic size adjustment: profile width and height are adjusted without manual intervention, so you move quickly from one purlin size to another.
• Black or galvanized strip: the machine works with hot-rolled Q195 or Q235 strip, black or galvanized, 1.5–3.0 mm thick, so you produce both galvanized sections for roofs and black sections that are painted afterwards.
• Integrated punching: the punching unit works after forming, with one or two holes in the web of the profile, round Φ14 mm / Φ16 mm or oval 28 × 14 mm / 28 × 16 mm, as you choose. Purlins come out ready for erection, without passing through a separate drilling machine.
• Cutting without changing the blade: the Cr12 steel blade and the stepless cutting system cut both profile types to length, without replacing the tool.
• Straight profiles, consistent quality: two biaxial straightening units and precision forming keep profile quality consistent from one piece to the next.
• Robust construction: solid shafts of 45# steel, heat-treated, shot-blasted and chrome-plated, ensure a long service life and stable operation.
The line is built from successive stations, each with a specific role in forming the profile. The configuration below is the standard one for LAZIRON CZ. We present it in full so your engineers can compare the line, station by station, with other offers received.
• Feeding: guide shaft and guide rollers, which bring the strip centred into the machine.
• Levelling device: 3 upper rollers and 4 lower rollers, plus 2 guiding and feeding stations. Solid shafts of 45# steel, heat-treated, shot-blasted and chrome-plated.
• Main forming rollers: 18 stations, including 1 station for forming the stiffening rib (adjustable to 87–95°). 13 stations are CZ changeover dies, which are turned manually through 180° to switch from one profile to the other.
• Rib forming: straight rib, which stiffens the web of the profile.
• Straightening rollers: 10 rollers for biaxial straightening dedicated to CZ profiles and another 4 rollers with biaxial straightening, for a total of 2 straightening units.
• Guiding and feeding: driven by upper and lower gears.
• Punching unit: punching after forming, with one or two holes, in the web of the profile only. Optionally, round holes Φ14 mm / Φ16 mm or oval holes 28 × 14 mm / 28 × 16 mm.
• Cutting: Cr12 steel blade and stepless cutting system, without changing the blade.

The machine produces C and Z purlins for steel buildings, prefabricated steel structures and roof support structures. It suits steel construction fabricators that deliver industrial halls, logistics warehouses, farms and agricultural buildings, where every project calls for different purlin sizes. With a C/Z purlin roll forming machine in your own plant, you no longer depend on the stock and lead times of a supplier of C sections or Z purlins.
Z purlins are often used on roofs with large spans, where the profiles overlap at the supports, and C purlins on walls, around openings and in secondary structures. When the same line produces a galvanized C section and a galvanized Z section, you can supply a building's entire purlin set from a single strip order and in a single production schedule.
On a market where steel buildings for industry, logistics and agriculture are going up at a steady pace, the purlin delivery date often decides when roof erection starts. A C/Z purlin roll forming machine in your own plant gives you control over this date and lets you produce the purlins in exactly the order the erection crew needs them, without large stocks of profiles waiting in the yard.
The machine is built with CE-certified components, in line with the requirements of the Machinery Directive 2006/42/EC. For the building's main structure, see the LAZIRON H-beam production line, which complements purlin production.
1. The steel strip, black or galvanized, 1.5–3.0 mm thick, enters the machine through the guide shaft and rollers and passes through the levelling device.
2. The operator selects the profile type (C or Z) and the dimensions on the PLC; width and height are adjusted automatically, and for the C/Z changeover the 13 changeover stations are turned through 180°.
3. The strip passes through the 18 forming stations, including the rib forming station, adjustable to 87–95°.
4. The formed profile passes through the two biaxial straightening units, then through the punching unit, which makes the holes in the web of the profile.
5. The Cr12 steel blade cuts the purlin to the programmed length, without stopping to change the tool.
6. The finished purlins are stacked by project and size, ready for delivery to site.
Production speed reaches 25 m/min and depends on punching frequency: the more holes a profile has, the lower the pace. For a correct capacity estimate, send us a few typical projects and we will calculate the output per shift together.
Daily operation is quick to learn: the operator feeds the strip, selects the profile and dimensions on the PLC and checks purlin quality at the exit. Training is included at commissioning and is done on your line, with the strips and sizes you use in current projects.
• Delivery, installation and commissioning, with operator training on your own parts.
• 60-month warranty and service with on-site response in under 24 hours in Romania (24–72 hours in other countries).
• Technical documentation for EU-funded, PNRR and public procurement projects.

Six technology directions we integrate turnkey: from plug & play IIoT sensors, to cobots, predictive maintenance, optical inspection, MES connectivity and custom industrial software.
See in real time how much each machine produces and how long it sits idle. We fit sensors on any equipment, new or old, and within a few hours you have the OEE dashboard on your phone. No complex wiring, no production downtime. The first concrete step toward digitalization, with ROI visible from the very first month.
Solve your labor shortage without tripling your costs. The cobot works safely alongside your people (palletizing, feeding the CNC, welding) while you recover the investment in 12-18 months. Prices 30-40% below European distributors, with installation and programming included from us.
Stop waiting for things to break. Our algorithms analyze sensor data and tell you exactly which part will fail and when, and we bring it to your production line before the breakdown. Zero unplanned downtime, zero contractual penalties, complete operational peace of mind.
Eliminate defects before they reach the customer. Our cameras inspect every part at speeds no operator can match, detecting sub-millimeter defects. They mount onto your existing line, with no modifications. Ideal if you produce for export and have strict quality clauses.
Connect your machines to your office, regardless of brand or age. Our gateway automatically translates the data from any machine into your ERP's format: no manual entry, no paper forms, no human error. The manager sees production live, the operator receives digital instructions.
Have a process that no off-the-shelf software can solve? We build custom industrial applications: from tailored SCADA panels and HMI interfaces, to production planning systems, lot traceability and automated reporting. The code is yours, it runs on your servers, with no monthly subscriptions or vendor lock-in.
