Wall Angle and J Track are metal framing components used mainly in drywall and suspended ceiling systems. They are not structural members; they are light-gauge steel accessories that provide alignment, fixing, and support.
One roll forming line is designed to manufacture both Wall Angle and J Track profiles, by:
Sharing the same base machine, decoiler, control box
Using separate rolls
This reduces investment cost and saves factory space.
Wall Angle is an L-shaped light steel profile, typically galvanized, fixed around the perimeter of a room.
Supports suspended ceiling grids
Forms a perimeter edge for ceiling systems
Provides a level reference line for ceiling installation
Supports drywall edges at wall intersections
Offices
Commercial buildings
Hotels
Hospitals
Retail spaces
Fixed to walls using screws or anchors
Ceiling grid or panels rest on the horizontal leg
30× 30 mm
40 × 40 mm
50 × 50 mm
Thickness: 0.4–0.6 mm
📌 Key point: Wall Angle does not carry structural loads — it mainly supports finishes.

J Track
J Track (sometimes called J-Runner) is a U / J-shaped steel track used as a guide channel for drywall studs.
Top and bottom track for drywall partition systems
Holds vertical metal studs in position
Creates door/window framing edges
Provides a neat finish at drywall terminations
Interior partition walls
Office layouts
Residential and commercial drywall systems
Fixed to floor and ceiling
Studs are inserted into the track and screwed
Web width: 50 / 64 / 75 / 100 mm
Flange height: 25–40 mm
Thickness: 0.45–0.8 mm
📌 Key point: J Track defines the wall layout and alignment, but the studs carry the vertical loads.

Decoiler (manual or hydraulic)
Roll forming stations: 9-10 stations
Thickness range: 0.4 – 0.8 mm (GI / PPGI)
Hydraulic stop-cut
PLC + touchscreen control
