Designed for metal roofing accessory manufacturers, this line provides efficient and safe production of precision ridge valley flashing profiles with punching function for interlocking roof panels.
This valley flashing profile is formed from galvanized steel sheets with a thickness of 0.3–0.8mm. It features pre-folded edges and punched trapezoidal notches for precise rib roof panel interlocking. It's widely used in residential, industrial, and commercial metal roofing systems for water sealing and structural transitions.

Process:
The forming section features chain-driven stations with protective guards and pre-folding rollers for edge bending. Punching is integrated mid-line after folding to produce accurate trapezoidal notches, ensuring smooth panel interlocking. The hydraulic cutter provides precise profile cutting for final flashing segments.
