PUTAI W Angle Roll Forming Machine – Shadow Line Wall Angle for Suspended Ceiling Perimeters

The PUTAI W angle roll forming machine produces the stepped perimeter trim that finishes the edge of a suspended ceiling where it meets the wall. The W angle's stepped profile creates a neat reveal, or shadow line, between ceiling and wall, giving a sharp, modern finish while hiding small imperfections in the wall surface. The machine forms 0.4–0.6 mm steel through 12 stations with Cr12 rollers and cuts each length with a servo cutting system, with delivery in around 35 days.

What Is a W Angle?

• A stepped wall angle fixed around the ceiling perimeter, supporting the edge of the ceiling grid or panels
• Its W-shaped profile creates a recessed shadow line between wall and ceiling
• Hides uneven walls and small gaps that a standard L angle would show
• Also known as shadow line wall angle, reveal wall angle, stepped wall angle or shadow trim
• Part of the drywall and suspended ceiling system, fixed directly to the wall

Why Contractors Specify W Angle

• A cleaner, more architectural edge than a plain L angle
• Masks out-of-level or uneven walls
• Premium look for offices, hotels and retail interiors
• Works with lay-in tile ceilings and plasterboard ceilings
