Product Details

Berntsen 2 ½" Aluminum Survey Markers for 1" Rebar

Berntsen aluminum survey markers for rebar are forged from 6000 series aluminum alloy which is highly resistant to chipping, cracking and breaking. They feature the SureGripT plastic insulator that locks the cap tight on to the rebar or pipe and helps prevent dissimilar metal corrosion. They feature a deep hex socket that won't "wobble" when tapped on to the rebar.

A good survey cap for rebar or pipe must virtually eliminate dissimilar metal corrosion. What typically happens is the survey cap loosens over a short period of time. This confirms metallurgical theory. Aluminum is less noble than steel and an electrical current will actually flow from the aluminum (+) to the steel (-). Corrosion will occur in the anode (+) area of the battery like combination of metals in the presence of moisture (air or soil acting like an electrolyte).

SureGripthumb.jpgBerntsen originated the SureGripT insulator/wedge which effectively isolates the survey cap from the steel and de-forms around the ribs of the rebar. The hex shape fills with the deformed plastic material and the survey cap is locked on with a super tight compression fit. Great force is required to remove the cap.

Our aluminium material is versatile and resistant to most environment conditions, however, if the survey markers are intended to be used in high traffic or caustic environments, such as roadways or salty conditions, we highly recommend using bronze survey markers to improve the lifetime of the markers.
