Profile Specification
S77 is a double skin profile roll-formed from a single pre-coloured steel section with a hot injection polyurethane central core, this bonds to the internal face of the section giving additional strength and rigidity.
The S77 profile also has a short throw reinforced quirk which interlocks each profile to form a continuous door curtain.
Heavy duty slat end-caps are pop rivetted to ensure that the curtain always runs smooth and square in the guide channel.
A reinforced carrier strip connects the 20mm deep base seal to the bottom rail, eliminating draughts and debris from passing under the closed door.
Note: Doors exceeding 5000mm clear opening incorporate an additional reinforcing angle to the bottom rail.
Optional reinforced wind lock anchors ensure the S77 continues to perform up to 1250 Pascals required for level 5 wind loading tests. |
