Decorative Cast Iron Grating Options for the Meadrain EN2000 Polymer Channel

The MEA Group is a large, multi-cultural manufacturing company based in Europe. Composed of 5 divisions, the Drainage division is one of the world’s leading manufacturers and suppliers of linear drainage systems. They specialize in polymer concrete and fiber reinforced plastic trench drain products. Here in the United States, the Josam Company of Michigan City, Indiana, is the representative for the MEA product lines.

One of MEA’s trench drain product lines is called “Meadrain”. Meadrain’s polymer concrete channel drains are available in 1 and ½ meter lengths, are of varying widths and are made with an assortment of integral metal edging. There is also a broad assortment of grating options available for each of the Meadrain channels. The photo to the left is the Meadrain Z1000 with a galvanized steel channel edging.

The EN2000 channel (shown right) is another example of integral metal edging. This is a popular product in the US and Canada. Neutral sloped channels are 8” wide and are available in three depths: 11”, 13” and 15”. The polymer concrete channels have “male-female” butt jointing features that make installation easier.

A typical 11” deep, one meter channel is 82 pounds in weight. Each channel has a knock-out for a 6” bottom outlet. Two sloped sections are available which are used for making “stepped fall” runs. Stepped fall sections make a transition between 11”-13” and 13”-15” deep channels.

 

The ductile iron channel edging is a distinctive feature of the EN2000. It helps protect the polymer concrete from deterioration during use. The edging is designed to accept standard bolt-down grates or MEA’s patented ProFix grate locking mechanism. ProFix grates have a pre-attached spring steel locking mechanism that snaps into recesses in the ductile iron channel edge.

 

Likewise, the solid polymer concrete end caps and end outlets have ductile iron edging. This is a feature not available in similar ACO trench drain products. MEA is one of the few manufacturers that still make end caps and outlet out of polymer concrete with the integral metal edging, as opposed to plastic.

The EN2000 is used in applications where heavy wheel loads will be frequent and where occasional large volumes of run-off water can occur. Food processing plants, maintenance facilities and fire stations are a few of the locations where a slotted ductile iron grate is commonly used as a trench cover in these conditions.


Decorative Options for the EN2000

The EN2000 can also be used in residential and commercial driveways where heavy wheel loads may occur or where the owner wants to create a vision of elegance and style. The ductile iron edging of the channel provides a nice border that accents the drain and separates it from the remainder of the driveway entrance. To help in adding the desired aesthetic, Iron Age Designs has developed two decorative grates that fit the EN2000 channel: Oblio and Greek Key.

 

One of the Iron Age patterns, named Oblio, is shown above in a Meadrain EN2000 channel. These custom grates measure 9” x 19.75” and weight 28 lbs each. The Oblio comes with holes that line up with the threading portion of the channel edging so the grates can be bolted into place. Typically, Iron Age grating is sold in the raw cast iron state. But, shown above, is a special finish call a “baked on oil finish” (or BooF). The baked on oil finish is an added cost that is growing in popularity, especially because it is both less expensive and longer lasting than a painted or powder coating.

 

The Greek Key pattern is the other Iron Age Grating that fits the MEA EN2000 channel. This version of the Greek Key pattern has a very tastefully designed border of what could be called “spears and shields”. Regrettably, this border does not appear in Iron Age’s 5” wide version of the pattern and, I believe, makes a big impact on the style and elegance of the grate. The Greek Key grate is shown here in its raw cast iron state. You can compare uncoated cast iron surface to the baked on oil finish of the adjacent Oblio grate.

One potential disadvantage of the Greek Key pattern is its lack of bolt holes for locking the grating into place. When grating is locked into place, it ensures that the grate will not shift and the highest possible load rating will be achieved. If the grate is able to shift within the channel and dirt is allowed to come between the channel and grate, it could set up a “rocking point” making the grating vulnerable to fracture when under stress. Another reason why lock down grating is important is that it reduces theft. It would be a shame to lose one of these grates to some kid looking to make money selling scrap metal, wouldn’t it?
