Roof Accessories V L Shape Metal Corner Flashing Roll Forming Machine 1

Roof Tile Accessories V / L Shape Metal Corner & Flashing Roll Forming Machine

This high-performance ZTRFM roof tile accessories roll forming machine is engineered for the automated manufacturing of precision metal roof accessories including V-shape ridge caps, L-shape corner flashings, sidewall flashing trims, and valley gutter profiles. Processing pre-painted steel (PPGI/PPGL), galvanized iron (GI), and galvalume coils (GL) in thicknesses from 0.3 mm to 0.8 mm with up to 1200 mm feeding width, this 8.0-meter production line features solid chrome-plated forming roller stations, progressive angle bending passes, a synchronized hydraulic profile post-cutter with no-deformation shearing dies, an automated PLC touchscreen control system, and 380V electric drive, delivering finished flashing trims at high speeds up to 30 m/min with effortless installation and zero surface paint scratching.

• Versatile Roof Tile Accessories: Produces customized V-ridge caps, L-shape corner flashings, sidewall weatherproofing trims, roof valley gutters, and gable verge trims in one continuous automated line.
• Broad Material Compatibility: Smoothly forms colored glaze steel (PPGI), pre-painted galvalume (PPGL), galvanized steel (GI), and aluzinc coils in thickness ranges from 0.3 mm to 0.8 mm.
• Precision Chrome-Plated Tooling Rollers: Solid carbon steel roller passes undergo precision CNC turning, heat treatment, and mirror hard chrome plating to eliminate paint scuffing and zinc layer peeling.
• High Speed 30 m/min Production: High-efficiency drive and chain transmission system enable continuous roll forming at speeds up to 30 m/min for high-volume commercial output.
• Hydraulic Profile Post-Cutter: Enclosed hydraulic cutting station equipped with profile-matching blade dies provides clean, burr-free, scrap-free cuts on the fly.
• Automated PLC Touchscreen Control: Automated batch length presetting, piece counting, and multi-language operator interface ensure simple setup and low labor requirements.

Technical Specifications

Machine Structure & Factory Production Line

The 8.0-meter heavy-duty bed is fabricated with high-rigidity welded steel channel bases, precision vertical arch stands, and yellow protective chain guards. Progressive forming passes gently bend the metal coil into sharp, uniform V and L angles without surface cracking.

Infeed Guide Table & Precision Forming Tooling

Dual handwheel adjustable infeed guide rollers center the coil strip before roll entry. Solid chrome-plated tooling rollers with calibrated spring-loaded vertical adjusters ensure consistent clamping pressure and precise bend angles across every batch.
