F Angle Shadow Angle Roll Forming Machine | PUTAI, Tianjin, China

PUTAI F Angle Shadow Angle Roll Forming Machine – Perimeter Profiles for Concealed Drywall Ceilings

The PUTAI F angle roll forming machine produces F profile shadow angles, the perimeter trim that gives concealed drywall ceilings a clean shadow gap where they meet the wall. The plasterboard edge sits into the F profile, which holds it securely while leaving a neat recessed line around the room. The machine forms 0.4–0.6 mm aluminium alloy through 18 stations with Cr12 rollers, producing profiles in 15 mm and 20 mm exposed widths with a 13 mm lip, and cuts each length with a servo cutting system. Delivery is around 35 days.

What Is an F Angle Shadow Profile?

• A perimeter profile shaped like the letter F, fixed to the wall at ceiling height
• The plasterboard edge slots into the profile, creating a crisp shadow gap between wall and ceiling
• Stabilises and defines the ceiling edge while keeping the finish discreet
• Suitable for both direct-fixed and suspended drywall ceilings
• Popular in modern residential, hospitality and commercial interiors

F Angle vs W Angle

• F angle: Holds the plasterboard edge in a concealed drywall ceiling, creating a shadow gap
