Lip Notch Punch is Important in LGS Assembly

Lip Notch: In the light gauge steel (LGS) industry, various punching processes are used to optimize the durability and assembly process of structures. One of the most common punches is the Lip Notch punch. This process is done to ensure that LGS profiles fit together smoothly during assembly, creating a flat surface. There are two types of Lip Notch punches in the LGS market, and both methods aim to make the assembly of light gauge steel structures more efficient, although they differ in their processes and outcomes.

In the first type, LGS machines bend the lips upward, trying to create a “U” shape during the process. This method involves bending the lips after the profile has been shaped by the rollformer. It is particularly effective with thinner steel profiles, facilitating the connection of the profiles. However, bent lips can cause problems with thicker steel profiles. In thicker steel (e.g., thicker than 1.2 mm), bent lips need to be flattened. If this flattening process is not done properly, issues may arise during the assembly of gypsum boards. The assembled gypsum panels may take on a “W” (wavy) form due to the bent lips, leading to both aesthetic and functional issues in wall panels. For this reason, the bending method is generally preferred for thinner steel profiles.

In the second type of Lip Notch system, the lips are completely cut off. In this method, the cutting process typically occurs before the rollforming stations, meaning the profile is cut before it is fully shaped. The cutting method offers several advantages during assembly. By cutting the lips, the steel profiles can slide into place more easily, and once the panel is assembled, it ensures a smoother and more accurate installation of cladding materials like gypsum board. This method eliminates the “W” form issue encountered with the bending process. It is highly effective with thicker steel profiles and is preferred in applications where higher structural strength is required. The cutting of the lips ensures a much easier and smoother assembly of profiles. Additionally, this method is more precise, as the alignment of profiles during the cutting process allows for fewer errors.

Bent lips in thicker steel can cause not only problems with gypsum board installation but also with other cladding materials. For example, metal cladding, wood paneling, or other building materials may be more difficult to install due to the bent lips. Cutting the lips properly prevents these issues, resulting in a stronger and more accurate structure.

UNBAK uses the second type of Lip Notch punching in its LGS machines, which involves cutting the lips. This method not only simplifies the assembly process but also ensures that cladding materials such as gypsum boards or other panels can be installed more smoothly after the panel has been assembled. Cutting the lips helps the profiles fit together better during assembly, ensuring that the final structure is flat and smooth. Moreover, this method helps create long-lasting, durable structures. By adopting this cutting method, UNBAK offers its customers more efficient, reliable, and long-lasting construction solutions.

The cutting method preferred by UNBAK not only facilitates easier assembly but also improves the overall aesthetics of the structure. Since the lips are cut, there are no undulations or imperfections on the surface of the panel. This results in a smoother appearance of the structure. Additionally, this method minimizes potential problems that could arise during the installation of cladding materials.

In conclusion, the Lip Notch punch plays a crucial role in light gauge steel systems. While there are two different methods, the cutting method used by UNBAK allows for more durable, flat, and easy-to-assemble structures. This speeds up the assembly process while ensuring the long-term reliability of the structures. Choosing the right punching method is crucial for achieving the best results in light gauge steel structures, and UNBAK ensures customer satisfaction by utilizing the latest technology and the most effective methods in this regard.
