What is a ninefold profile?
The nine-fold profile gets its name from the nine curves in the column and beam structure. It is made from cold-rolled steel plate that has been rolled by a roll forming machine.
Before detailing the process of using a press brake to bend a nine-ply profile, let's first discuss the use of the nine-ply profile.
Nine-ply profile applications
Nine-ply profiles are mainly used for cabinet production. Cabinets made with these profiles have a closed column and beam structure, providing greater strength compared to traditional open beam and C-profile structures. They offer high strength, low cost, take up minimal space and are highly preferred by users. The technology to process these cases was developed by the Rittal Company in Germany and has since been copied by domestic Chinese companies.
Ninefold profile cabinet materials:
The materials used for the nine-ply profiles include national standard cold-rolled steel plates and high-quality stainless steel, such as SUS304L for the food and beverage industry, SUS316L for the medical and pharmaceutical industry, and SUS201 as an option economical stainless steel.
The thickness:
- Door panel: 2.0mm;
- Cabinet body: 1.5 mm;
- Bezel: 1.5mm;
- Back and side panels: 1.5mm;
- Mounting plate: 3.0 mm (2.5 mm optional).
Nine times profiled cabinet surface treatment:
The steel plates for the cabinet body, base and door undergo 12 international standard pre-treatment processes, including pickling, phosphating, dewaxing, washing and purification. After these processes, the surface is covered with plastic and can be painted in any color you want. Stainless steel is normally treated with double-sided design.
Standard components of a nine-fold profile cabinet include:
- Nine-fold profile frame
- Front door
- Mounting plate
- Back plate
- Top plate
- Side plate
- Base
- Rim
- Three-stage galvanized power base plate
- Pair of perforated beams
- Three-point double tooth lock for tie rod
- Handmade strap lock
- Galvanized Square Tube for Cabinet Door
- Reinforcing ribs
- Polyurethane foam sealing tape.
Typically, the nine-ply profile can be purchased rather than manufactured in the sheet metal shop. Under special circumstances, sheet metal manufacturers can also bend their own profiles.
