Custom Pre Punching Roll Forming Line For Durable Galvanized Steel Silo Panels

Custom Roll Forming Line for Durable Galvanized Steel Silo Panels with Pre-Punching and Hydraulic Bending

These introductions refer only to the production line and configuration shown in the main image. Each machine is custom-built. Metalign welcomes your inquiry and provides the right production line—forming metal into profiles aligned to your needs.

1. Production Line Overview

• This advanced roll forming line is designed for agricultural and industrial applications, particularly for the production of heavy-duty galvanized steel panels. The line is ideal for silo manufacturers and offers efficient pre-punched hole systems, continuous production, and high durability for long-lasting agricultural storage structures.

2. Profile Description

• The panels produced by this line are crafted from high-quality galvanized steel, measuring 3-4mm in thickness. Their purlin profile features pre-punched holes, ideal for the construction of agricultural silos. Designed for strength and longevity, these panels are perfect for use in industrial and agricultural storage applications, ensuring resilience and ease of installation.

3. Production Process

• 5T Decoiler → Guide System → Leveling Unit → Waste Coil Collection → Roll Former → Hydraulic Punching → Hydraulic Bending Machine → Hydraulic Cutting

• The process starts with the decoiler to unwind the steel coil, which is then leveled by the independent leveling unit. Following this, the steel sheet is formed into a purlin profile by the 20-station roll former. The tracking hydraulic punching machine creates holes as the panel is formed. Afterward, the bending machine adjusts the curvature, followed by cutting with the hydraulic cutting station.
