Due to the premature failure of corrosion protection systems on cable supported structures, D.S. Brown began development of its patented Cableguard™ Elastomeric Cable Wrap System in the early 1990’s. This alternative corrosion protection system, developed exclusively for bridge cables, is applicable during construction or rehabilitation of cable-stayed and suspension bridges.

9. 1. Use the Skewmaster™ wrapping
machine to apply Cableguard™
between cable bands with a 50%
overlap
2. Heat the wrap for 5-10 minutes
to create a permanent bond
3. Seal the cable bands using a
neoprene wedge and finishing
strip
4. Apply anti-slip walkway surface
to the topside of the wrapped main
cables

1. Use the Skewmaster™
wrapping machine to
apply the Cableguard™
continuously with a 50%
overlap
2. Apply heat

17. Cable Dehumidification for Suspension Bridges
Dehumidification of enclosed steel cables and anchorages on suspension
bridges is accepted and employed as an active corrosion protection method
on landmark bridges worldwide.
Cableguard™ - Dehumidification

18.  Three Primary Components of Dehumidification
• An effective sealing system such as Cableguard™. In addition to the
main cable, this system also seals the cable bands.
• A dehumidification plant produces and blows dry air through the
cables.
• A control and monitoring system automatically adjusts the system to
real time conditions.
