Product Overview

The Chile & Peru Double Layer Roof Sheet Machine is engineered for Latin American metal building manufacturers, roofing contractors, and regional coil service centers. The 5V Crimp profile is widely recognized across South America for its inverted V-shaped stiffening ribs that provide superior rigidity against tropical storms, while the sinusoidal wave profile remains the standard for agricultural sheds and residential roofs.

The machine handles standard 1000mm wide coils of prepainted galvanized steel (PPGI), galvalume (PPGL), and galvanized steel across thicknesses from 0.3mm to 0.6mm. Producing both 5V panels and corrugated sheets on a single 15-ton double-deck machine saves 50% factory floor space and reduces capital expenditure by over 40% compared to two separate production lines.

Key Technical Features

• Hard Chrome Plated Forming Rollers: Precision CNC turned from 45# forged structural steel, vacuum quenched, and electroplated with 0.05mm hard chrome to eliminate coil scuffing and preserve painted finishes.
• Independent Dual-Tier Hydraulic Cut-Offs: Upper 5V blade and lower corrugated blade operate via independent high-pressure hydraulic cylinders, ensuring crisp distortion-free cuts across both profiles.
• Massive 350H Beam Chassis Frame: Normalized structural steel foundation relieves internal welding stresses, guaranteeing long-term station alignment under continuous high-speed production.
• Ultra-Thick Ø80mm Solid Shafts: High-frequency quenched solid 45# shafts supported by heavy-duty self-aligning bearing blocks withstand heavy radial forming loads.
• Heavy Double-Row Roller Chain Transmission: High-tensile drive chains deliver steady rotational torque to upper and lower roller shafts without slippage.

Multi-Pass Dual-Tier Progressive Roll Stands

The machine features two vertically integrated rolling levels mounted onto the 350H foundation. Upper and lower passes are precision engineered to gently contour colored coil stock without surface micro-cracking or paint peeling.

• Upper Deck (5V Crimp): Progressive roll passes shape the sharp V-grooves and side laps without stretching the metal crests.
• Lower Deck (Corrugated): Center-outward progressive bending forms uniform sinusoidal arcs with consistent pitch.
• Heavy Double-Row Roller Chain: Synchronized heavy roller chains distribute powerful rotational torque across all stands.

Perfil 5V & Sinusoidal Wave Geometry

Both profiles comply with South American building and roofing cladding specifications:

• Perfil 5V Crimp: Features 5 inverted V-ribs across the sheet width for high structural stiffness and hurricane resistance.
• Sinusoidal Wave Profile: Classic circular arc geometry delivering maximum natural water drainage and cost efficiency.
• Weatherproof Overlap Seams: Precision overlap flanges guarantee 100% weather tightness against heavy wind and driving rain.

Broad Agricultural & Industrial Applications

This 2-in-1 dual machine fulfills 95% of architectural sheet metal roofing demand across Latin America:

• Commercial Steel Warehouses & Factories: High wind resistance and fast installation over steel purlins.
• Agricultural Buildings & Sheds: Traditional curved roofing, silo cladding, and agricultural barn walls.
• Residential Carports & Roof Retrofits: Lightweight, economical metal roofing over existing timber rafters.

Supply Scope & Ocean Shipping

Turnkey supply scope includes 5-ton manual decoiler (hydraulic decoiler optional), double-layer roll forming main machine on 350H frame with protective covers, dual-tier hydraulic cut-off station, standalone hydraulic pump station, Siemens PLC touchscreen console, and finished panel runout tables.

All precision chrome rollers and shafts are coated with anti-corrosion protective grease. The 15-ton machine chassis is securely anchored inside a 40ft HQ shipping container using heavy steel wire cables and timber chocks. The electrical control console and hydraulic station are hermetically wrapped in waterproof film and crated in export plywood cases.
