Precision-machined 45# forged steel roller stations with hard chrome plating shape 4 uniform trapezoid ribs progressively with zero surface blemishes.
Heavy-duty hydraulic cut-off station equipped with custom GCr12MoV profile blades shears panels cleanly at exact preset lengths with ±1.0 mm tolerance.
Calibrated infeed table with side positioning rollers guides 1220 mm wide metal coils smoothly into the first forming station without lateral drifting.
Finished 4-rib trapezoidal panels stacked neatly, featuring sharp rib crests, flat drainage valleys, and tight lap joints ready for construction sites.
A: PV4 features 4 pronounced trapezoidal ribs with broad flat pans between ribs, providing higher structural strength and greater rain discharge volume than shallow sinusoidal waves.
A: Yes. The hard-chromed rollers process prepainted steel (PPGI), Aluzinc/Galvalume, and hot-dip galvanized coils (0.3–0.8 mm) without damage to surface coatings.
A: Cutting lengths and total batch counts are entered directly on the PLC touchscreen in seconds, and the machine automatically counts and cuts pieces with ±1.0 mm precision.
