TerraLog 100 Steel Log Siding Wall Panel Roll Forming Machine 15–22 m/min

The TerraLog 100 Steel Log Siding Wall Panel Roll Forming Machine is designed to manufacture rounded metal wall panels for exterior construction and architectural applications. Unlike conventional flat wall panels, this specialized wall panel roll forming machine produces a distinctive double-course profile with two large curved surfaces, creating the appearance of traditional log siding while maintaining the strength and dimensional consistency of roll-formed steel.

With a 354.17 mm formed width, 406 mm feed width, 31 mm profile depth, and approximately R160 curved sections, the machine is engineered around the TerraLog 100 profile. It continuously converts galvanized or color-coated steel coils into finished wall panels through automatic feeding, progressive roll forming, hydraulic cutting, and PLC-controlled operation.

The machine is suitable for residential buildings, cabins, commercial projects, exterior renovation, and other applications requiring a log-style metal wall panel.

What Is the TerraLog 100 Steel Log Siding Profile?

TerraLog 100 is a specialized rounded metal siding profile developed to reproduce the appearance of stacked wooden logs using formed steel wall panels.

The profile contains two approximately 159.7 mm rounded faces, separated by a central formed section. The large curved surfaces create the characteristic log appearance, while the formed edges provide the connection structure required for panel installation.

The main profile dimensions include:

• Formed width: 354.17 mm
• Feed width: 406 mm
• Rounded face: approximately 159.7 mm × 2
• Curve radius: approximately R160
• Profile depth: 31 mm
• Typical materials: GI / PPGI / color-coated steel
• Common gauges: 24ga and 26ga

Because the TerraLog 100 profile contains large-radius curves and formed connection details, the rollers of the wall panel roll forming machine need to be designed according to the actual profile drawing. This allows the machine to maintain consistent curvature and dimensional accuracy throughout production.

How Does the Wall Panel Roll Forming Machine Work?

The TerraLog 100 production line uses a continuous coil-to-panel process:

Steel Coil → Decoiling → Guiding → Roll Forming → Length Measurement → Hydraulic Cutting → Panel Collection

First, the decoiler supplies the steel coil to the production line. The feeding and guiding system then aligns the strip before it enters the forming section.

The wall panel roll forming machine uses multiple forming stations to gradually bend the flat steel strip. Instead of creating the R160 curves in a single operation, each roller station introduces a controlled amount of deformation until the material reaches the final rounded profile.

During this process, the forming rollers also create the center section and edge connection details. Progressive forming helps reduce surface marks, wrinkles, and profile distortion, especially when processing galvanized or pre-painted steel.

Once the profile reaches its final shape, the hydraulic cutting system cuts the continuous wall panel according to the preset length. The finished panels are then transferred to the receiving table for inspection, stacking, and packaging.

TerraLog 100 Wall Panel Roll Forming Machine Specifications

The final configuration of the wall panel roll forming machine can be customized according to the customer's profile drawing, material thickness, production speed, and electrical requirements.

Progressive Roll Forming for Rounded Wall Panels

The large curved surfaces are one of the most important features of the TerraLog 100 profile.

The approximately R160 radius requires controlled progressive forming. If the steel strip is bent too quickly, the finished wall panel may develop wrinkles, surface marks, or inconsistent curvature.

Therefore, the roller stations of the wall panel roll forming machine gradually develop the two rounded faces. Each station performs a controlled forming operation, allowing the material to transition smoothly from a flat coil into the final double-course profile.

The roller design also incorporates the center groove and side locking sections. As a result, the finished wall panels can maintain both their visual appearance and required installation geometry.

Machine Structure and Forming Rollers

The TerraLog 100 wall panel roll forming machine uses a 350H steel main frame to support the forming stations and transmission system. A rigid frame helps maintain roller alignment during continuous production.

The forming shafts are manufactured from 45# steel with a 50 mm diameter, while the rollers use 45# steel with chrome treatment. These components provide the strength and wear resistance required for long-term roll forming operations.

The forming section normally includes approximately 14–18 stations, although the exact number can be adjusted according to the final profile design.

Chain or gear transmission can be selected according to the machine configuration and production requirements.

PLC Control and Automatic Production

The electrical control system coordinates feeding, forming, length measurement, and cutting.

The standard wall panel roll forming machine uses a Delta PLC and Delta frequency converter, together with an Omron encoder for accurate length measurement.

Operators can enter the required panel length and production parameters through the touch-screen control system. The PLC then coordinates the forming and cutting operations automatically.

The control interface can support English and Chinese, while additional languages can be customized according to customer requirements.

This automated system reduces repetitive manual work and helps manufacturers maintain stable production during long production runs.

Hydraulic Cutting System

After the steel strip reaches the required TerraLog 100 profile, the hydraulic cutting system separates the continuous material into individual wall panels.

The cutting unit adopts a four-guide-pillar structure to improve cutting stability. The Cr12 quenched cutter provides suitable hardness and wear resistance for repeated steel cutting operations.

Under suitable production conditions, the cutting tolerance can reach approximately ±1.5 mm.

Accurate cutting is especially important for wall panel production because consistent panel lengths simplify transportation, stacking, and installation at the construction site.

Applications of TerraLog 100 Wall Panels

The wall panels produced by this wall panel roll forming machine can be used for various exterior construction applications, including:

• Residential exterior walls
• Log-style houses
• Cabins and recreational buildings
• Commercial buildings
• Architectural wall decoration
• Exterior renovation projects
• Metal siding projects
• Construction projects requiring a wood-log appearance

The finished panels combine the appearance of traditional rounded logs with the manufacturing efficiency of roll-formed steel.
