A Cut-To-Length line is a popular method of creating flat, rectangular blanks from larger metal coils.  Also known as a CTL or a Blanking Line, our machine will uncoil the larger material or master coil, straighten or flatten it, and then cut it to the required length as it moves through the line, and ultimately stack it into a bundle. The process will uncoil the metal from the master coil, flatten it, cut it to the required length as it moves through the line, and stack it.

Equipment technical parameters

Steel does not come off of a larger coil in a flat form.  It needs to be stretched into flatness while on the CTL.  Our machine uses roller leveling technology to stretch and compress the material, some are with 4-Hi lever, some are with 6-Hi lever.  This method increases flatness tolerance and material stability.  The ultimate use of the cut material may warrant precision cutting accuracy that meets your exact specifications.

  PVC/PET PPGI is a laminated material including a metal layer and a PVC film layer available in many different color patterns and emboss. Many options are available including solid colors, printed patterns, high-gloss options to satisfy various design requirements. This material can be used in typical metal forming processes such as bending, cutting, and pressing.This material can be used for outdoor applications by laminating a weather-resistant PVC film.

PPGI with PVC film is widely utilized in many different applications due to its excellent weatherbility, corrosion resistance and a variety of colors and patterns.

PPGI with fliming we have the following types for your reference:

4. Good touch: There is a layer of film on the surface, and the touch is smooth, which changes the cold and single feeling of the metal material.
5. Many designs and colors: a variety of colors to choose from.
6. Anti-corrosion: The surface can use high weather-resistant outdoor film as the surface layer of weather-resistant film.
7. Good heat insulation: heat-reflective heat-insulating aluminum foil film or weather-resistant outdoor cold film can be used as the heat-insulating surface layer on the surface. The temperature difference between indoor and outdoor can be increased by more than 8 degrees.

Mode 3: PVDF Metal Film Faced Panel

The antistatic agent added to the surface nano-ageing resistant film in the PVDF metal coated sheet increases the smoothness of the film surface, reduces the friction coefficient, and prevents electrostatic adsorption of dust. After 4000 artificial aging experiments by the Building Materials Inspection Center, the retention rate of solar reflectance was 82%, and the retention rate of gloss was 81%, and its anti-aging performance was better than the standard.

Galvanized Steel Coils is also called hot-dip galvanized steel coils as it is produced by immersing steel in a zinc bath, which requires a pretreatment process when steel passing through different baths for preparing the surface zinc coating. First, use chemicals to clean surface of the steel then another chemical treatment for the steel coils passing through a bath of melted zinc at temperatures around 460 degree. When finished the products shows smooth and shiny appearance. To store for a longer period, the hot-dip galvanized coils can be delivered with a final oil coating, according to the customer demand. If processed by further cold forming and bending processes, it will has much better ability.

Where to use:

Galvanized steel coils are widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommend for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 100 180 grams per square metre.

How to protect Galvanized Steel Coils?

• Oiling–Putting oil on machine can reduce the corrosion of steel plate under wet storage conditions and then it is much more easier to store.  But when oiling, please make sure not damage the degreasing agent zinc layer.
• Sealing–Put transparent organic thin layer coating on the surface of product can provide add additional protection against corrosion, especially fingerprint resistant. And when forming, this method can improve lubricity and then use the layer as bottom adhesion.

3. Phosphating– phosphating treatment is fit for various galvanized steel, in addition to the normal cleaning, no further treatment needed for phosphating. Resistance and anticorrosion coating adhesion can improve this process, reducing corrosion of the danger when storage and transportation. After phosphating you can add some suitable lubricant, this method can improve the forming performance of galvanized steel coils.

Note: we will not take any protection methods stated above without getting customer permission.
