Protect your buried facilities from damage
Berntsen Concrete Utility Warning Markers are a perfect defense against damage to buried facilities.
The bronze "C" style markers are the equivalent of the Corps of Engineers Type 1 disc, and can be customized online with your imprint. The C style is a one-piece forged marker made with a split-style flared solid stem.
These markers can be placed in either wet concrete or drilled and epoxied into existing concrete.
Brass has been used in the manufacture of survey monuments and markers for many years. Iron pipe monuments with brass caps were used by federal government surveyors as early as the first part of the 20th century. Certain brass alloys, notably those with a high lead (a hazardous material) content, equal or greater than five (5) percent, are now viewed as archaic metals. Alloys that are typically used in survey monument components were Leaded Semi-Red Brass 81-7-9 (7 percent lead) and Leaded Red Brass 85-5-5 (5 percent lead). Few customers require these alloys for any reason other than tradition.
Berntsen’s Better Way
Berntsen pioneered the introduction of non-leaded brass alloys for survey monuments and markers in the mid-1980’s. Through our continued research and testing we have found that brass or bronze alloys containing high amounts of coppers, provide the best characteristics in corrosion resistance, strength and durability. We now exclusively use silicone bronze alloy (97 percent copper, 2 percent silicon) for our cold forged survey markers and caps. In an independently conducted test, Berntsen’s silicon bronze cap was found to have essentially no corrosion after 240 hours of salt spray per ASTM B-117-16.
