Profile
Gutter: Metal gutters are commonly used for drainage along the edges of building rooftops, primarily to collect and channel rainwater. Common styles include half-round type and K-style type. They are typically made of metal materials ranging from 0.3-0.8mm, such as aluminum, pre-painted steel, or galvanized steel.
Ridge cap: The ridge cap is set where the two sides of two roof panels meet, also known as the roof's top. It is typically used to enhance the sealing and aesthetics of the roof. Ridge caps are usually crafted from pre-painted steel or galvanized steel ranging from 0.3-0.8mm.

Real case-Description
- Decoiler
For ridge cap and gutter, the configuration of the decoiler is nearly identical, utilizing hydraulic decoilers with a load capacity of 3 tons each. Given the varying widths of steel coils used for ridge cap and gutter, it is better to allocate a dedicated decoiler for each production line. This approach minimizes downtime during coil replacement and enhances operational efficiency for each production line.
Guiding
The guiding rollers ensure alignment between the steel coil and the roll forming machine, preventing distortion during the forming process.
Roll forming machine
This roll forming machine employs a wall-panel structure and a chain driving system. Unlike conventional dual-row setups featuring two different sizes of the same profile, this machine handles entirely distinct profiles on each row.
It's important to note that the two rows cannot operate simultaneously. We recommend dedicating a separate production line for each profile if you have higher production demands.
Additionally, metal covers have been installed over the chains to protect workers from accidental contact with rotating chains and to safeguard the chains against damage from dust and debris.
Hydraulic cut
The cutting machines are fixed on this production line, halting the movement of the steel coil during cutting. For the clients require the higher production speed, we offer a flying cutting machine that the base can smoothly traverse forward and backward on rails at the same speed of the roll forming machine. This innovative design enables the steel coil to progress through the forming machine without interruptions during cutting, thereby significantly boosting the overall efficiency of the production line.
At the end of both rows, the cutting blades are meticulously crafted to precisely match the contours of the respective profiles. This ensures that the edges on the profiles are undistorted, maintaining the highest standards of precision and quality.
Hydraulic station
Supplies the initial power to the cuter through a closed oil tank. It is off without cutting, which can save the power.
The hydraulic station is equipped with cooling fan, facilitating efficient heat dissipation to ensure prolonged and optimal operation. With a low failure rate and exceptional durability, the hydraulic station guarantees reliable performance over the long term.
PLC control cabinet & Encoder
The roll forming production line is quipped with the encoder form Japanese brand KOYO. The encoder keeps translating the detected lengths of steel coils into electrical signals, transmitting them to the PLC control cabinet. Operators can adjust production speed, quantity, and cutting lengths. The cutting machine achieves remarkable accuracy thanks to the encoder's precise measurement and feedback, keeping cutting errors within ±1mm.
