System Components
Cast-in-place Steelflex®
Strip Seal Expansion Joint Systems
consist of two
proprietary components: steel rail
profiles and a matching neoprene sealing
element.
Steel Rail Profiles
Steelflex® rail profiles
are one-piece construction, manufactured
using innovative hot rolled/non-machined,
non welded. All proprietary steel
rails are available in ASTM A36 or
ASTM A588/A572 steel grades.
Recent design improvements have eliminated
all horizontal
"legs" on the proprietary
steel rail profiles to facilitate
proper concrete placement during installation.
Independent field and laboratory testing
has demonstrated that improperly consolidated
concrete around the steel rail, anchorage,
and/or reinforcement could lead to
performance issues. Anchorage of the
proprietary steel rail profile into
the dec_ concrete is the primary load
carrying mechanism and, therefore,
is it critical to ensure long-term
performance.
Steelflex® SSCM2 rail profile
has become widely accepted worldwide
as an economical standard in the industry.
Other proprietary steel profiles are
also available to satisfy your specific
project needs.
