QuicKey™ [Patent No. 6502359] and PRO-KEY™ [Patent No. 5380122] are stay
in place metal keyed control joint formers for use in concrete flatwork
as a control or construction joint. The tongue and groove design provides
excellent load transfer characteristics for heavy, wheeled traffic and also
prevents uneven settling associated with aggregate interlock. The use of
a metal keyed control joint eliminates costly form stripping and saw cutting
and slow checker-board placement of concrete.
Material:
QuicKey™ and PRO-KEY™ are manufactured of 24 gage, G60 hot dipped mill galvanized steel. They are furnished in 10' lengths for 4", 5", 6", 8" and 10"-12" slabs. Each piece is punched on 6" centers with dowel rod knockouts.
QuicKey(tm) LOCKING-TAB(tm) stakes are manufactured from 13 gage HRPO steel and are available in 12", 15", 18", 24" and 30" lengths.
PRO-KEY™ LOCK SLOT™ stakes are manufactured from 16 gage HRPO steel and are also
available in 12", 15", 18" and 24" lengths.
Both keyed control joint formers are mill galvanized before fabrication
and conform to ASTM A 924, ASTM A 653 CQ or LFQ.
The corresponding stakes are manufactured from hot rolled, pickled
and oiled steel conforming to ASTM A 569.
