Product Overview

The ZTRFM Pre-Shearing Cut-to-Length Before Forming Automatic C Z Steel Purlin Production Line is an advanced high-speed manufacturing solution engineered for fabricating heavy-duty C and Z structural steel purlins. Featuring pre-shearing and pre-punching flat strip blanks before entering the forming mill, GCr15 bearing steel vacuum-quenched tooling, a 22 kW high-power drive, and automated size changeover, it operates at speeds up to 35 m/min while processing 1.5–3.0 mm high-tensile galvanized steel without end flare or profile distortion.

Key Engineering Features

Pre-Shearing Before Forming Design: Cutting and punching flat strip prior to roll forming completely eliminates blade interference during size changes and prevents profile end flare.
GCr15 Bearing Steel Roller Tooling: Vacuum-quenched GCr15 die steel rollers deliver extreme wear resistance (HRC 60-62) and mirror surface finish for smooth continuous heavy-gauge forming.
High-Speed 35 m/min Productivity: Automated 22 kW drive transmission and continuous strip feeding significantly boost output capacity over conventional post-cut machines.
Integrated Hydraulic Pre-Punching: High-precision hydraulic cylinder punches web and flange mounting holes accurately per PLC program parameters.
Comprehensive 5T Decoiler Included: Heavy-duty 5-ton decoiler supports heavy coil loads and ensures smooth, continuous payout into the leveling and pre-shear station.
Extended 5+ Years Factory Warranty: Industry-leading manufacturer warranty covering core structural frame, shafts, and drive train assemblies.

Subsystems & Mechanical Details

1. Hydraulic Pre-Shearing & Pre-Punching Unit

Pre-Cutting C Z Purlin Machine - Hydraulic Pre-Shearing and Punching Unit

Heavy-duty hydraulic shearing station cuts flat strip to exact length and punches bolt holes before entering forming stands, completely eliminating cutter die changeovers.

2. GCr15 Bearing Steel Precision Forming Roller Stands

C Z Purlin Roll Former - GCr15 Bearing Steel Precision Forming Rollers

Precision-machined GCr15 bearing steel rollers mounted on heavy solid shafts progressively shape 1.5–3.0 mm high-strength steel into sharp, rigid C and Z purlins.

3. Finished High-Tensile C & Z Steel Purlins Stacking

Finished C Z Steel Purlins - High Tensile Galvanized Purlins Stacking

Straight, burr-free purlin profiles with precise pre-punched hole patterns allow dense bundle packing for freight and direct bolt-together erection on jobsites.

4. Structural Steel Building Framework Installation

Steel Structure Building Frame - C Z Roof Purlins and Wall Girts Installation

Installed as roof purlins and wall girts across industrial portal frames and multi-story steel structures, supporting heavy roof and wall cladding panels.

5. PLC Touchscreen Industrial Control Console

C Z Purlin Machine - PLC Touchscreen Industrial Control Console

User-friendly touchscreen terminal manages automated recipe storage, automated pre-punching spacing, cut-to-length quantities, and real-time line diagnostics.

Application Scenarios

Industrial Steel Structures: Secondary framing for commercial warehouses, manufacturing workshops, and logistics centers.
Commercial Buildings & Hangars: Mezzanine floor joists, aircraft hangars, shopping malls, and distribution facilities.
Agricultural Facilities: Corrosion-resistant galvanized framing for livestock barns, grain storage sheds, and equipment depots.

Frequently Asked Questions (FAQ)

Q: What is the main advantage of pre-shearing before forming?

A: Pre-shearing cuts flat strip before profiling, which avoids complex profile-matching cutting dies, completely prevents end flaring/warping, and eliminates tool changeover time when switching sizes.

Q: Why is GCr15 roller material preferred for purlin machines?

A: GCr15 bearing steel provides superior hardness (HRC 60-62) and extreme abrasion resistance, ensuring long service life without dimensional wear when forming heavy 3.0 mm steel.

Q: What warranty and after-sales support are provided?

A: We provide an industry-leading 5+ Year factory warranty, engineer overseas installation service, and lifelong remote technical support.
