Condition: new, Year of construction: 2025, Standing seam roof panel machine F3-39 (1.5 inches) Standing seam roof panel machine F3-39 logically complements the line of machines for double standing seam roof panels production we make. In Europe, the most common is 25 or 27mm lock high, but outside of Europe, in some parts of America and Canada regions seam metal roofing with 39mm lock high is also popular. That is why our company decided to start production equipment for such task, to expand sales geography, and to bring our products to more and more customers who may need it. Metal roof machine F3-39 has additional rolls for clip-relief rolling, which come as standard set of machine supply. Clip-relief is a small bend locating closer to the locks of panel and which make possible to hide fixation clips under the panel. Standing seam machine F3-39 has 8 pairs of main rolls to make the main part of the lock and a ninth stand to make clip-relief part. Godpfx Aoq U N T Rshzeud The rollers and base of machine are stronger comparing to standard version of equipment – roof panel roll forming machine F3. It has also rolls of bigger diameter to make 39mm (1.5 inches) lock. Despite all these increases, standing seam roof panel machine F3-39 is portable one, our customers can directly take it to construction place, and you can use it at the roof installation site as well. Thus giving the customer opportunity to reduce number of panel’s damages and the transportation cost. There is drawing of panel you can get with our F3-39 machine Roof panel roll forming machine F3-39 can make panels with clip relief or without it, depends on customer preferences. Machine can work with coated materials or without coating as well. Suitable for steel coils, copper aluminum, zinc etc. It’s possible to adjust gaps between rollers depends on material thickness customer use for forming. Standing seam metal roof machine has easy adjustable system to change the width of the panels. The machine operator just need to rotate adjusting wheel to make it happens As additional options you can get Length measuring device to set up number and lengths of panels; Cross cutting knife for metal cutting; Rolls for ribbed panels production; Floor decoiler; Hand seamers for lock closing; Sliding clip formers; Fixed clip former. Our company can produce other machines for metal roofing production: Standing seam metal roof machine F3 for 25mm lock high; Standing seam machine F3-27 for 27mm lock high; Snap lock roof panel machine SL-1; Automatic snap lock metal roofing panel machine SL-1 auto;

It allows the metal plate to be fed in one single pass, completing pre-bending and roll forming of the workpiece without the need for turning over the plate. The upper working roller serves as the main drive roller, while the lower roller and two side rollers are hydraulically driven. Their lifting strokes are controlled by the CNC system, enabling automatic leveling with a synchronous display accuracy of ±0.1 mm. The tilting and resetting of the tilting bearing housing adopts a hydraulic transmission structure, and the upper roller is equipped with a balancing mechanism to facilitate the removal of the finished workpiece. The machine comes with a movable independent control console for flexible repositioning at any time, and is equipped with safety interlock devices to ensure safe and reliable operation. Working Roll Material The working rolls are made of 42CrMo high-strength premium alloy steel, manufactured through forging, rough machining, and quenching & tempering heat treatment, achieving a bulk hardness of HB 240–300. After finish machining, they undergo medium-frequency induction hardening, resulting in a surface hardness of HRC 47–58. The products comply with the JB/ZG4289-86 standard for roll steel, ensuring uniform roll rigidity with a controlled deflection of (1/700–1/1000)L. Note: L refers to the center distance between the two side frames. The entire production process strictly follows the standard manufacturing flow for rolls, fully guaranteeing the comprehensive mechanical properties of the working rolls. Working Roll Rotation & Drive System The upper roll is the driving roll of the four-roller rolling machine. It is fitted with an independent hydraulic motor directly coupled to the heavy-duty gear housing, with no intermediate gear transmission. This is the most energy-efficient drive design. The hydraulic motor is equipped with an instant braking device, enabling accurate positioning of the roll shaft during pre-bending operations. Double-row spherical roller bearing Excellent Self-aligning Performance The outer ring adopts a spherical structure, allowing the inner ring and roller assembly to deflect within an angle of 1.5°~3°. It can automatically compensate for misalignment caused by installation errors and shaft deflection, preventing seizure and abnormal wear. Heavy Load & Impact Resistance Line contact between rollers and raceways enables the bearing to withstand extremely high radial loads as well as bidirectional axial loads, perfectly suited for heavy-duty working conditions of rolling machine rolls. High Durability Made of high-strength bearing steel with quenching and other heat treatments. Combined with a well-designed lubrication system, it ensures long-term stable operation under harsh conditions and greatly reduces downtime for maintenance.
