Self Lock Standing Seam Metal Roofing Roll Forming Machine

The Self Lock Standing Seam Metal Roofing Roll Forming Machine is an automated cold bending forming equipment designed specifically for producing 360 ° edge biting metal roof panels. The entire production line usually consists of an uncoiler, feed guide, rolling forming host, servo fixed length cutting (or flying shear), discharge platform, and electrical control system. Optional bending arc device, film sticking device, and palletizing mechanism can be equipped. This equipment can produce trapezoidal, curved, or straight edge seam roof panels in the factory or directly transported to the construction site. After the panels are rolled and formed, the two side ribs are interlocked, and then locked by an automatic interlocking machine to form a 360 ° waterproof self-locking structure, without the need for screws to penetrate the panel surface, fundamentally eliminating leakage hazards.

Application Scenarios:

Large span public buildings, such as airport terminals, high-speed railway stations, exhibition centers, and sports venues, require ultra long seamless roof panels and curved shapes that are highly compatible with the aesthetic and waterproof advantages of self-locking edge seam systems.

• Industrial plants and logistics warehouses:
High requirements are placed on roof waterproofing and durability, and usually have large areas and long boards. On site mobile machines can produce the required board lengths in real time without overlapping, resulting in extremely high construction efficiency.

• Commercial and residential metal roofs:
High end villas, resort hotels, clubs, etc. use aluminum magnesium manganese or titanium zinc sheet edge seam roofs, requiring a flat and scratch free surface. Machines need to be equipped with felt rollers or nylon rollers to ensure surface quality.

• Renovation and renovation of old roofs:
Lightweight metal roofs can be directly covered on the original roof, and on-site production can quickly measure and shape them to adapt to irregular building contours.

• Special climate areas:
coastal high salt spray areas, high wind pressure areas, and extremely cold areas. Stainless steel or weather resistant steel plates can be produced, combined with high-strength self-locking buckles, to meet strict requirements such as typhoon resistance and corrosion resistance.

Features:

1.Fully automatic online forming:
integrating unwinding, forming, and cutting, it can produce roof panels of any length as needed on the construction site, breaking through transportation limitations, especially suitable for ultra long or irregular panels.

2.High precision rolling system:
The rollers are made of high-quality alloy steel and undergo heat treatment and precision grinding to ensure stable cross-sectional dimensions of the plate. The height and width tolerances of the plate ribs are controlled within ± 0.3mm, and the bite is tight and reliable.

3.Self locking waterproof design:
The produced board has a 360 ° vertical edge self-locking buckle, which is matched with a dedicated electric or pneumatic edge locking machine. After biting, it is tight and stable, with strong wind resistance and can adapt to extreme temperature changes from -50 ℃ to+80 ℃.

4.Online bending function:
Optional servo controlled bending mechanism can be used to directly process the roof panels with positive, negative, or variable curvature arcs during the forming process, meeting the needs of irregular buildings such as sports venues and domes.

5.Flexible production switching:
By replacing some rolls or adjusting shims, one device can be compatible with multiple plate widths (commonly 300-620mm) and rib heights (such as 25mm, 38mm, 65mm) to meet different engineering design requirements.

6.Mobile vehicle design:
Most models can be integrated into containers or trailers to achieve fully mobile on-site production, greatly reducing the cost and deformation risk of long board transportation.|

Frequently Asked Questions (QA):

Q1: What materials can this machine produce for roof panels?
A: It can handle coil materials such as color coated steel plates, galvanized aluminum steel plates, aluminum magnesium manganese alloy plates, titanium zinc plates, stainless steel plates, and copper plates. The yield strength of materials is usually between 240-400MPa, with a thickness range of 0.5-1.2mm.

Q2: What are the molding speed and on-site production efficiency?
A: The stable molding speed is generally 10-20m/min, depending on the plate type and material. A device equipped with a vehicle mounted mobile device can produce thousands of meters of roof panels per day, fully meeting the schedule requirements of large-scale projects.

Q3: What is 360 ° vertical edge self-locking and how is it different from traditional locking?
A: 360 ° vertical edge biting refers to the process of fully interlocking and flipping the male and female ribs 360 ° through a specialized locking machine after forming the plate ribs, forming a tight mechanical bite without any capillary channels inside. Its waterproof and wind resistance performance is much better than that of ordinary biting methods such as 180 ° or 270 °.

Q4: Can we produce curved plates? How to achieve it?
A: Okay. By installing a computer-controlled bending device, bending force can be applied to the plate during the forming process to produce positive, negative, and variable curvature curved plates with a minimum radius of about 30 meters, suitable for complex shapes such as domes.

Q5: Is the machine convenient for transportation and transfer?
A: Most models are designed as split or container integrated vehicle structures, which can be transported by a flatbed truck and produced upon arrival at the construction site by connecting the power supply. Fast lifting and fixing, very suitable for mobile construction projects.

Q6: Does your device support cutting to length and punching?
A: Standard flying shear or shutdown cutting, with a cutting accuracy of ± 2mm. If necessary, an online punching die can be configured to punch installation holes, drainage holes, etc. on the board surface or rib, and the punching accuracy and position can be programmed.
