Bending, Slitting, and Roll-Forming of Color-Coated Coils: Core Deep-Processing Technologies

Bending, slitting, and roll-forming are the core deep-processing technologies for color-coated coils. Through these processes, coils can be transformed into finished products suitable for different scenarios. The detailed introduction is as follows:

I. Bending Process: Shaping Three-Dimensional Structures for Complex Forms

Bending of color-coated coils is a process that uses a bending machine to apply pressure to flat color-coated sheets, making them form specific angles along the fold line. Its key characteristics are as follows:

Process Parameters

Processing can be carried out at room temperature. The minimum bending radius is usually 1.5-2 times the thickness of the sheet (e.g., the minimum bending radius of a 1mm-thick sheet is 1.5-2mm). The bending angle can be adjusted as needed (0°-180°). After processing, the coating adhesion must remain at Grade 5B (cross-cut test) to avoid cracking and peeling.

Application Scenarios

It is mostly used to manufacture products requiring three-dimensional structures, such as mechanical casings, equipment guards, and building keels. For example, color-coated sheets with a thickness of 0.8-1.5mm are bent at a 90° angle and welded into distribution box casings, which balance protection and aesthetics.

Advantages

No high-temperature heating is required; the process is simple and efficient. It enables multi-batch, small-volume customization to meet the shape requirements of different products.

II. Slitting Process: Precision Cutting into Narrow Strips for Segmented Needs

Slitting is a process that uses a slitting machine to cut wide color-coated coils into multiple narrow coils or sheets along the length direction. Its main characteristics include:

Process Parameters

The slitting width can be precisely controlled, with a minimum width of up to 50mm and a length error of ≤±1mm. The cut edges need to be deburred (burr height ≤0.1mm) to prevent scratches on the coating.

Application Scenarios

It is suitable for scenarios requiring narrow-width materials, such as the production of billboard frames (width 100-200mm) and PV bracket connectors (width 80-150mm). The slit narrow strips can be used directly or further processed.

Advantages

It can efficiently cut large coils into specifications suitable for downstream needs, improving material utilization and reducing subsequent processing costs.

III. Roll-Forming Process (Tile-Forming): Shaping Various Profiles, Focusing on Construction Applications

Roll-forming (also known as tile-forming) is a process that uses a multi-pass roll-forming machine to continuously roll color-coated coils into profiles with specific wave shapes or forms. Its core characteristics are as follows:

Process Parameters

It can be formed into various profiles such as trapezoidal tiles (wave height 25-35mm), corrugated sheets (wave pitch 100-300mm), and tongue-and-groove panels. After forming, the angle deviation of the profile is ≤±1°, and the length can be customized as needed (usually 6-12m).

Application Scenarios

It is mainly used for building roofs and walls, such as trapezoidal tile roofs of factories (thickness 0.3-0.8mm) and corrugated exterior wall panels of light steel villas (thickness 0.5-1.0mm). The formed profiles are connected by lapping or standing seams, providing excellent waterproofness and structural stability.

Advantages

It enables automated continuous production with high efficiency (the daily output of a single production line can reach 1000-3000㎡). The formed products have enhanced strength and can be directly used for construction and installation, shortening the project cycle.

These three processes together form the key transformation link of color-coated coils from raw coils to finished products, enabling them to flexibly adapt to the differentiated needs of construction, industry, decoration, and other fields.
