Product Overview

The Corrugated Roofing Sheet Roll Forming Machine is engineered for metal roof tile manufacturers, agricultural shed builders, steel warehouse contractors, and residential building suppliers. Sinusoidal wave corrugated iron sheets represent the most time-tested and widely utilized metal cladding profile worldwide due to their exceptional water shedding and cost efficiency.

Capable of forming pre-painted galvanized iron (PPGI), galvalume (PPGL), and galvanized steel coils across thicknesses from 0.4mm to 0.8mm (22-28 gauge) and feeding widths of 915mm, 1000mm, 1100mm, or 1250mm. The formed corrugated panels deliver superior rigidity against wind uplift and provide complete weatherproofing for industrial warehouses, agricultural barns, and residential roofing.

Key Technical Features

• Mirror Hard Chrome Plated Sinusoidal Rollers: All forming roller dies are CNC turned from 45# forged structural steel, vacuum quenched, and electroplated with 0.05mm hard chrome to eliminate coil scuffing and preserve paint finish.
• Full-Contour Wavy Hydraulic Cut-Off: High-tonnage hydraulic cutting station fitted with Cr12 vacuum-quenched blades machined to the exact sinusoidal arc cross-section ensures distortion-free panel ends.
• Solid Ø70mm 45# Steel Shafts: High-frequency heat-treated solid shafts supported by heavy-duty spherical roller bearings resist bending forces under high-tonnage rolling cycles.
• Heavy Structural Bed Frame: High-rigidity steel foundation normalized to relieve internal welding stresses, guaranteeing long-term station alignment.
• Protective Safety Guarding: Sturdy yellow side covers protect drive chains and sprockets, shielding operators from hazards and preventing foreign object interference.

Progressive Sinusoidal Bending Progression

Forming circular sinusoidal waves requires symmetrical progressive deformation from the center of the sheet outward. The line features 12 to 16 graduated roll forming stations designed to prevent lateral sheet skew, surface scratching, and edge elongation.

• Center-to-Edge Roll Forming: Gradual arc formation prevents residual stress and eliminates edge wavy warping.
• Heavy Double-Row Chain Drive: High-tensile drive chains synchronized with precision sprockets deliver smooth rotational power across all stands.
• Independent Bearing Blocks: Heavy-duty spherical bearings with individual lubrication nipples ensure smooth 24/7 continuous operation.

Corrugated Wave Geometry & Engineering Blueprint

The corrugated profile complies with international standard building specifications (including ASTM A792, BS 3083, AS 1397):

• Effective Cover Width: 910.6 mm / 820 mm / 32" (813 mm) coverage width
• Wave Pitch: 76.2 mm (3.0") or 2.67" (68 mm) on-center circular corrugations
• Wave Height / Depth: 18 mm (or 0.875" 22 mm) arc amplitude for optimal water discharge
• Natural Overlap Nesting: Smooth sinusoidal crests allow precise nesting with standard 1.5 to 2 corrugation side overlaps for leak-free roofing.
