7/8″ Corrugated Metal Panels Roll Forming Machine

This is an industrial production line designed to continuously uncoil, feed, and press flat metal sheets into a classic, continuous sine-wave pattern where the depth (height) of the ribs is exactly 7/8 of an inch. These panels are heavily used for roofing, siding, and architectural applications in agricultural, commercial, and residential projects.

These 7/8 ” ​Corrugated Metal Panel Roll Forming Machine is engineered to handle a variety of standard roofing materials, including:

• Galvalume and galvanized steel

• Pre-painted (color-coated) steel

• Aluminum The typical material thickness ranges from 29 gauge to 22 gauge (approximately 0.3mm to 0.8mm), which covers most standard commercial and residential roofing requirements.

The 7/8″ depth is considered a “deep” corrugation compared to standard 1/2″ or 1/4″ profiles. This deeper rib provides significantly higher structural integrity and spanning capabilities, allowing it to be installed over open purlins at wider spacings. It also channels high volumes of rainwater incredibly efficiently.

Standard roll formers for this profile typically operate at speeds of 15 to 25 meters per minute (roughly 50 to 80 feet per minute). The exact speed depends on the thickness of the material being run and the cutting frequency determined by the programmed panel lengths.

Forming a deep 7/8″ wave requires careful metal manipulation to prevent the steel from stretching, tearing, or oil-canning. The 7/8 ” ​Corrugated Metal Panel Roll Forming Machine utilizes a series of 16 to 22 heavy-duty, hard-chrome plated roller stations. The rollers are engineered to form the corrugations from the center of the panel outward, pulling the metal in smoothly and incrementally until the final 7/8″ depth is achieved.

The 7/8 ” ​Corrugated Metal Panel Roll Forming Machine is equipped with a hydraulic post-cutting shear. The upper and lower cutting blades (dies) are custom-machined via CNC to perfectly match the 3D topographical profile of the 7/8″ sine wave. When the machine pauses to cut, the blades completely encapsulate the panel, shearing the metal cleanly without crushing or flattening the heavy ribs.

• Panel Width: Yes, the machine can generally accept different raw coil widths (e.g., 36″ vs. 42″), which will simply result in a finished panel with fewer or more ribs and a different overall coverage width.

• Wave Depth: No. Because the rollers are solid steel cut specifically for a 7/8″ depth and a specific pitch (distance between peaks), you cannot use the same rollers to make a 1/2″ or 1-1/4″ corrugated panel. Doing so would require a completely different machine or a highly advanced dual-level (double-deck) machine.

o ensure consistent, scratch-free panels and prevent machine wear, operators should:

• Wipe down the chrome rollers regularly to remove zinc dust, dirt, or metal shavings.

• Keep the drive chains to properly tensioned and lubricated.

• Grease the main bearings on a regular schedule.

• Monitor the hydraulic oil levels and periodically inspect the 3D cutting blades for dullness or burrs, sharpening them when necessary to ensure a clean edge.
