Product Overview

The Hat Profile Omega Purlin Roll Forming Machine represents an essential structural framing production line for modern pre-engineered steel buildings (PEB). The hat/omega profile (often referred to as top hat purlin, roof batten, or furring channel) provides superior structural stability compared to conventional channel sections due to its symmetrical dual-flanged geometric cross-section.

This production line seamlessly handles galvanized steel coils (GI), cold-rolled coils (CRC), and prepainted galvanized steel (PPGI). With automated hydraulic pre-punching, progressive multi-stand forming, and length-controlled hydraulic shear, operators can produce pre-punched structural purlins ready for immediate jobsite bolt assembly.

Key Technical Features

• Inline Hydraulic Hole Punching Station: Multi-cylinder hydraulic punching station punches round holes and slotted holes at precise programmable centers for quick bolt fastening.
• Cr12 Die Steel Forming Rollers: Rollers precision CNC machined from vacuum heat-treated Cr12 tool steel, providing extreme hardness and surface finish.
• Cardan Shaft & Gearbox Transmission: Separate side gearboxes interconnected via industrial universal joints deliver positive drive to upper and lower shafts.
• Distortion-Free Hydraulic Cut-Off: Heavy guided hydraulic profile shear with Cr12 dies eliminates deformation across the 120mm deep profile walls.
• 8,000kg Heavy Structural Frame: Heavy H-beam bed frame normalized and precision-planed guarantees station stability and eliminate vibration.

Technical Specifications

Progressive Forming & Pre-Punching Stations

Forming high-yield steel into a 120mm deep Hat/Omega channel without side-flare or twist demands precision multi-pass gradual contouring. The line incorporates leading-edge engineering features:

• Heavy Leveling Feeder: Multiple precision leveling rolls relieve coil set and longitudinal residual stress before shearing or punching.
• Multi-Point Hydraulic Punching: Hydraulic cylinders operate modular punching dies that stamp elongated bolting slots and circular tie-rod holes at high speed.
• Modular Station Tooling: Cr12 hardened rolls maintain microscopic dimensional tolerances, allowing nestable stacking for cost-effective freight shipping.

CAD Profile Geometry & Structural Advantages

The hat/omega profile cross-section offers distinct structural engineering advantages:

• 120mm Deep Section: High moment of inertia and bending stiffness, spanning wide distances between primary roof rafters.
• 30mm Dual Outward Flanges: Provides solid continuous bearing surfaces for direct fastening onto steel rafters or concrete purlins.
• Compact Nestable Stacking: Tapered web geometry allows profiles to nest inside one another, cutting container shipping volume by over 60%.

Broad Agricultural & Industrial Applications

Hat profile omega purlins serve critical structural roles in commercial and industrial construction:

• Metal Roof Battens & Sub-Purlins: Direct support purlins beneath trapezoidal and corrugated roofing sheets.
• Solar Ground & Rooftop Mounting Racks: Rigid, pre-punched structural purlins for mounting solar PV arrays.
• Modular Building & Agricultural Framing: High load-bearing framing for poultry houses, barns, and prefabricated modular units.

Supply Scope & Ocean Shipping

Standard complete production line includes manual / hydraulic decoiler, multi-roller leveling entry unit, hydraulic multi-cylinder pre-punching station, roll forming main machine with independent gearbox drives, Cr12 hydraulic profile shear, standalone hydraulic pump station with air cooler, PLC touchscreen control desk, and product runout tables.

All Cr12 tool steel rollers and solid shafts are coated with high-performance rust inhibitor. The 8-ton machine frame is reinforced and secured inside a 40ft HQ ocean container using high-tensile steel wire tensioners. Electrical control desks and hydraulic stations are crated in export-standard wooden cases.
