1. Production Line Overview
Designed for downspout manufacturers and metal roof system
suppliers, this line offers safe structure, decorative
reinforcement, and efficient square pipe production for residential
and commercial drainage needs.
2. Profile Overview
This square downspout is formed from galvanized steel coils with
0.3–0.6mm thickness. It features reinforced embossing lines for
added strength and aesthetics. Commonly applied in roofing systems,
it resists deformation under weather conditions and provides stable
water drainage for various building types.

Process:
The steel coil is guided into the roll former, where it is embossed
and formed into a square downspout profile using a stable
wall-panel frame and chain drive system. Hydraulic shearing ensures
precise cutting.
4. Technical Parameters
