There are many sizes and many regular holes for cable trays, so how to change the size and how to punch the holes is the main issue when the manufacturer design the machine.
Nowadays, more and more adopt to uncoiler, independent pre-leveling device, servo feed in device, presser with different punching dies, roll former, stop to cut or flying cut device, no power run out rack or pneumatic stacker, PLC control systems as complete lines to improve the production speed largely
Here is one drawing profile and finished product:
ZTRFM Slotted Stud And Track Forming Machine is the industry preferred system for achieving head-of-wall deflection and fire resistance for interior and exterior walls. It has met the movement and cycling requirements of ANSI/UL 2079 and is UL Classified for 1, 2, 3, and 4 hour fire-resistant ratings in head-of-wall fire-rated joint systems.
Slotted track features and applications:
- Fire-rated deflection system
- UL Classified in over 80 approved fire-rated systems
- Standard Slotted Track allows up to 1½” of vertical movement
- Custom shapes and slot sizes available
- Custom widths and thicknesses available
- Positive attachment provided for wall strength
- Absorbs head-of-wall and floor extension or compression movement
- Integrated with traditional wall systems
- Easy installation reduces labor costs
Benefits
· Lighter weight means lower cost: Because we use less steel to produce it, Steel slotted track is a cost-effective solution for head-of-wall system needs.
· U.L. Fire Rated: With code-approved fire ratings of up to 2 hours, you can trust Steel slotted track for your head-of-wall system.
· Save money in the long-term: We use a full zinc coating to greatly minimize rust formation, meaning your walls will last longer. Steel framing is not compromised by termites or mold, and holds up better against acts of nature when compared to wood framing.
· Earn LEED Credits: Due to levels of recycled content in the coils we use, our steel studs are considered a green product.
