Understanding the 9-Fold Profile Frame

The nine-fold profile is a profile that folds a cold-rolled steel plate with a thickness of 1.5mm nine times to form nine folds, and the cross section of the nine folds is a sealed curved labyrinth pattern. In the production process, the nine-fold profile is rolled into a nine-fold profile with a roller forming machine, and the molding process makes the nine-fold profile more robust.

The pioneering technology for the nine fold profile was originally developed and patented by Rittal GmbH & Co. KG, a well-known German company specializing in industrial enclosures and power distribution systems. Subsequently, several Chinese manufacturers adopted and adapted the technology, contributing to its widespread availability in the global market. In recent years, the technology patent expired, and many Chinese manufacturers began production, including our Vililong.

9-fold profile frame is simply a frame composed of a nine-fold profile and a three-way connection element

The 9-fold profile frame is a closed column and beam structure, which has higher strength, better load-bearing capacity and less space than the traditional open beam and column and C-profile structure. Its integrated profile frame makes the combination of the cabinet shell and the frame more compact.

Multiple cabinets are installed by combining cabinets. In the application scenario, the space is fully utilized to stabilize the load, expand the heat dissipation area, and effectively solve the problem of heat concentration.

The cabinet is widely used in data centers, automobile manufacturing, new energy (photovoltaic power generation), tobacco equipment, rail transit and metallurgical equipment and other fields. In the outdoor environment, including sea water, sea wind, precipitation, snow melt and even salt spray, water vapor will not invade, to ensure the normal work of the electronic components in the box. Ideal for industries requiring electromagnetic shielding, high robustness and good heat transfer performance. The protection level can be IP54.

The material used for the nine-fold profile frame cabinet includes national standard cold-rolled steel plate and high-grade stainless steel, such as SUS304L for the food and beverage industry, SUS316L for the medical and pharmaceutical industry, and economic SUS201 stainless steel for choice.
