Maintenance & Daily Attention
Daily Check (Every shift)
Clean roller surface to remove iron dust, galvanized scraps; do not scratch roller surface with hard tools.
Check hydraulic oil level, oil leakage of cylinder and pipeline. Normal hydraulic pressure: 10–14 MPa.
Check whether cutting blade and punching die have chipping; sharpen or replace immediately if burr appears on finished purlin.
Check chain tension, add lubricating oil for transmission chain.
Check emergency stop button, safety cover and electrical cabinet door seal.
Weekly Maintenance
Lubricate all bearing seats with lithium grease.
Fasten loose bolts on forming frame, cutting base and hydraulic station.
Calibrate encoder and test length cutting accuracy.
Clean cooling fan inside PLC cabinet, check cable terminals for oxidation.
Monthly Maintenance
Filter or replace hydraulic oil if oil turns dark; hydraulic oil recommended: 46# anti-wear hydraulic oil.
Check rollers for wear; when profile size drifts obviously, arrange roller surface repair.
Test PLC backup battery; replace battery once a year to avoid program loss.
Check grounding wire to prevent static and electric shock risk.
Long-term storage & safety notes
Shut down power and hydraulic pump after work; release residual pressure of hydraulic system.
Do not adjust roller gap or touch moving parts when machine is running.
Operators must receive formal training before running the line.
Keep workshop dry; avoid water entering electrical cabinet and hydraulic station.
From Steel Coil to Structural Components
A Z-purlin production line combines several operations to convert flat steel strip into finished members. The sequence and equipment arrangement should be selected according to the product drawings and required manufacturing output.
Coil Preparation and Feeding
The decoiler supports the steel coil and supplies material to the production line. Its capacity must correspond to the required coil weight, width, and thickness.
Material guiding and feeding components help align the strip before it enters the forming section. Correct feeding conditions are important for maintaining consistent material tracking.
Progressive Cross-Section Formation
The steel strip passes through a series of forming stations. Each station introduces a controlled amount of bending until the web, opposing flanges, and lips reach the specified geometry.
The forming design must account for material properties, thickness, and profile dimensions. The number and arrangement of stations should be determined by the actual engineering requirements rather than treated as a universal specification for every Z-section.
Punching for Structural Connections
Where required, punching equipment produces holes or slots according to the approved drawings.
The selected tooling and process sequence depend on the hole layout, material thickness, profile geometry, and accessibility of the punching locations. These details should be settled before the production line is finalized.
Cutting to Order Lengths
After forming, the profile is cut to the required finished length. Cutting settings and the selected cutting method must correspond to the material and section dimensions.
For manufacturers producing different lengths in the same order, the control arrangement should support the intended production sequence and length-setting requirements.
IUWON Factory Introduction
IUWON is a professional cold roll forming equipment manufacturer located in China, focusing on steel structure profile machinery for more than 15 years. Our product portfolio covers Z purlin machines, C purlin machines, roof panel roll formers, floor deck machines, guardrail roll forming lines and customized special profile equipment, serving steel structure contractors, prefab house factories and metal product manufacturers across Southeast Asia, Middle East, Latin America and Europe.
We have independent R&D workshop, CNC machining center, heat treatment workshop and assembly workshop. Every Z purlin machine will go through 72-hour continuous running test before shipment to check forming precision, hydraulic stability and electrical logic.
IUWON provides one-stop service: drawing confirmation, production tracking, factory inspection, overseas installation guidance, operator training and spare parts supply. We accept OEM & ODM, can adjust forming range, punching layout and automation grade according to your local project standard.
Application of Z Purlin & Z Purlin Making Machine
Z purlin produced by this machine acts as secondary load-bearing member for steel structure building envelope, mainly for roof supporting. Thanks to its lap joint design, Z purlin performs far better than C purlin on continuous long-span roof system.
Typical application scenarios:
- Large-span steel workshop, industrial factory
- Logistics warehouse, distribution center
- Prefabricated steel building, commercial mall roof
- Agricultural shed, livestock farm, greenhouse steel frame
- Airport terminal, railway station auxiliary steel structure
- Solar bracket auxiliary supporting purlin
Finished Z purlin supports matching with color roof sheet, insulation layer and wall cladding. It is widely used in projects requiring high load capacity and long span.
What to Confirm Before Ordering
The most useful equipment quotation is based on a defined production specification. A small number of unresolved technical details can affect roller design, punching tooling, machine configuration, and acceptance testing.
Profile Drawings
Provide dimensioned cross-sections showing web height, flange widths, lip dimensions, and relevant angles. If several sizes are required, include a drawing or dimension list for each specification.
Material Requirements
Identify the steel grade, coating, thickness range, and coil specifications. If material thickness varies between orders, state the minimum and maximum values clearly.
Punching and Cutting Details
Include hole diameters, slot dimensions, spacing, edge distances, finished lengths, and any other connection requirements. These details should be shown in the approved drawings whenever possible.
Production Expectations
Explain the target output, number of working shifts, typical order sizes, and expected frequency of size changes. This information helps determine the appropriate level of automation and material handling.
Installation Conditions
Confirm the factory's available floor space, electrical supply, coil handling arrangements, and destination country. The final layout and auxiliary equipment should reflect the actual installation environment.
