Overview Points

G550 Steel Processing

Forms edge protectors from G550 high-strength steel strip up to 1.2mm thick for maximum protection.

Three Roll Sizes

1,300mm, 1,600mm, and 2,000mm diameter options match standard steel coil dimensions.

Cr12MoV Tool Steel

Hard-wearing Cr12MoV rollers extend service life and reduce tooling replacement costs.

Thin Material Handling

Processes material as thin as 0.35mm without tearing for flexible protector specifications.

Compact Design

1,100 × 800 × 1,000mm footprint integrates into existing packaging lines without layout changes.

Energy Efficient

3kW motor provides adequate torque for continuous high-strength steel forming with low power draw.

Standard Power Supply

380V/50Hz electrical compatibility with custom voltage options for different facility requirements.

Gear Drive System

Visible gear transmission ensures reliable operation and simplified maintenance access.

Key Features

Engineered to process G550-grade steel — one of the hardest commercial strip grades — at thicknesses from 0.35mm to 1.2mm, the machine produces rigid edge protectors that resist deformation under coil weight and strapping pressure.

Available in 1,300mm, 1,600mm, and 2,000mm roll diameter configurations, each size corresponding to commonly produced steel coil outer diameters, so the finished protector seats flush against the coil edge without gaps or overhang.

Forming rollers are machined from Cr12MoV cold-work die steel, a material chosen for its high hardness (58–62 HRC), wear resistance, and dimensional stability, which translates directly into longer runs between tooling service intervals.

At just over one square meter of floor space, the Outer Roll Machine integrates into coil packaging lines alongside strapping, wrapping, and stacking equipment without requiring layout redesign or additional foundation work.

The 3kW direct gear drive eliminates hydraulic systems and their associated fluid maintenance, filtration, and leak risks, keeping both energy draw and upkeep requirements minimal for single-shift or continuous operation.
