Detectable Warning Systems CastIron Premium Gray Warning Plate

Continuing to cultivate innovative growth into the multi-million dollar warning surfaces market and build upon their rich history of product development via their proprietary Detectable Warning Systems (DWS) safety product line, Mar-Bal, Inc. (Mar-Bal: Chagrin Falls, OH) is progressively launching their CastIron premium gray iron detectable warning plate.

Made in the USA, this cast iron plate was developed to be installer friendly while meeting or exceeding ADA and DOT specifications for detectable warnings.

Designed for use in cold harsh climates with snow removal concerns, as well as entities desiring longer-term durability, the CastIron plates feature premium Class 35 grade gray iron strength–the highest level made in the USA.

A unique “rib” design makes it lighter (45.0 lbs.) than standard competitive plates on the market. This equates to an easier and quicker installation without sacrificing strength or rigidity.

Installations are further simplified by a central vent hole that releases trapped air, which also provides an even-set with no ensuing bubbles. Additionally, an advanced interlocking system fits easily and securely for perfectly aligned multiple-unit/adjacent plate installations.

Already one of the industry’s most complete lines of ADA compliant tactile warning surfaces, the addition of DWS’ CastIron superior slip-resistant truncated dome plates offers contractors, distributors, states, and municipalities a durable, proven tactile warning product specifically designed for easier installations and backed by a 7-year warranty.

CastIron Interlocking Installation:

CastIron’s plates can be installed quickly and easily in comparison to similar products on the market. After pouring concrete in designated areas and finishing to a smooth texture, simply place the detectable warning plate(s) in the specified location in regard to the curb line and ramp boundaries.

The Interlocking Installation system makes it easy. One side features two arches that extend outside the panel on the bottom. The other side features two tabs on the end (see image on the left).

After setting the first plate down (do not fully imbed in the concrete), the next plate is installed by putting the tabs on the bottom into the arches. This is the key to the Interlocking System which keeps adjacent panels together in the correct alignment.

Simply continue this process until all plates have been set onto the wet concrete. Finally, embed the plates flush with the concrete by tapping with a rubber mallet until they are level with the surface of the concrete. Any air under the plates will be evacuated through the air vent on the top.
