Hubbell, the makers of the Polycast trench drain product line, has been busy at improving its product lines.  The manufacturer recently introduced four new ornamental cast iron grating products which fit their Polycast 500 deck drains and Polycast 600 pre-sloped trench drains.  In addition to these, they have also begun offering a heavy duty ADA compliant ductile iron grate that can be used with their 700 Series product line to achieve a class F load rating.  These new grates are a welcomed addition to their current full selection of standard commercial grating options.

The main difference between the Polycast 600 and Polycast 700 series products is a frame.  Both systems utilize the same polymer concrete pre-sloped channels, the same end caps and installation hardware.  However, when a 700 frame (cast iron or HDPE) is used with a 600 series channel, the system is instantly transformed into a 700 series channel which is capable of much higher load ratings when using a cast iron grate.  For instance, a standard Polycast 600 channel with a ductile iron grate (DG0641D) is capable of class D loading, which should be able to withstand an eighteen-wheeled tractor with trailer.  When that same channel/grate combination utilizes the DG0700aa cast iron frame, the system is able to withstand the 747 jumbo jet at your local international airport, which requires a class F loading.  If you use the high density polyethylene frame (DG0700PE) in this scenario, the load class changes to class E, which is appropriate for fork truck traffic.

A recent addition to Polycast’s grating options is the DG0675HD ductile iron grate.  This product, shown above, is ADA compliant and heavy duty enough to be used in heavy load applications.  Though it is a slotted grate, it doesn’t look as industrial as standard slotted grates.  And, while not technically heel-proof, the narrow openings of this grate make it very “heel-friendly”.  The longitudinal slots help define this grate as ADA or wheelchair compliant, I feel that this grates slots give it a sleeker look which make it a more attractive option for residential drainage applications.  When used with one of the 700 series frames, the system gains both strength and aesthetics which make it an ideal selection for commercial and streetscape applications.

For applications which require a higher degree of aesthetics, ADA compliancy and higher load ratings, Polycast has their new decorative cast iron product line.  They have joined the ranks of manufacturers such as, NDS, Iron Age Designs, Zurn and Polydrain (ABT) that have decorative cast iron grating offerings.  Finally!!!  In the world of pre-sloped, commercial grate trench drain products, Iron Age is the leader in ornamental trench grating (who, by the way, make most of ABT’s decorative grates).  Zurn has a small, and somewhat boring collection of decorative grates that they sell at a premium.  NDS developed a handful of economically priced products which have not really been promoted as well as I feel they should be.  Now, “better late than never”, Polycast has developed four grates which are appealing to the eye and handsomely priced.  Let’s take a look-see.

The photo above shows the Abbott (DG0693) and the Spiral (DG0694).  The Abbott is geometrically floral and harkens to an earlier time when mosaics and repeating geometric patterns dominated architecture.  It is a solid bodied grate that will stand the tests of time.  The Spiral pattern is a more eloquent pattern that is reminiscent of ancient Greece.  The thin top webbing is supported underneath with a structural mesh.

Above are two more Polycast decorative grating options:  Patriot and Cobblestone.  The Patriot (DG0692) is my favorite of all the Polycast patterns.  It displays the “stars and stripes” theme which is a common revolutionary war era design.  I expect to see this used in the historic districts of Boston and Philadelphia.  Likewise, the Cobblestone design (DG0695) is an old style pattern suitable for a stone driveway or fieldstone house.  Both grates are rugged and offer an added component of grace to the streetscape or estate where they are used.

There is another important point to bring up about these grates.  They fit exclusively in the Polycast 600 and 700 series trench drains.  This is important because I feel that the Polycast system is the best polymer concrete, pre-sloped channel drain on the market.  There are plenty of other commercial grade drain products in the same class.  But, in my humble opinion, the patented installation hardware and longer channel lengths of Polycast make it the easiest to install while offering the best value for the money.

Meet the 12” x 20” Locust grate by Iron Age Designs.  This grate is made for custom Iron Age frames and is typically used in suspended walkways and stairs (see it in action HERE).  We had a sample available and brainstormed about innovative ways to use trench drain grates.

Ultimately, we decided to custom paint the grate and use it as a decorative planter stand for our office plant life.  It really came out beautifully…  I’ve included details on the process with photos below:

The first stage was to create a base coat that would be the natural color of the grate.  The paint I used was gray enamel designed to protect metals against rust.  After spraying an initial layer, I returned to coat the corners and crevices – just to ensure that there would be no rust-vulnerable area on the grates.

The grate dried in the sun for several hours until the paint was no longer soft.  Then we baked it at low heat (150 F) in an electric oven for 15 minutes so that the paint hardened.  Because paint is simply pigment suspended in a bonding agent, paint relies on a long evaporation process to become dry. The theory in baking the grate was to reinforce that process.

I wanted my final background to be bright and have a clean surface to show through, so I painted the grate white.  It took a few touch-ups here, too, to make sure that I had an even coating.  I baked the grate again and let it cool before continuing.

Early on the grate’s design, I’d decided on a blue-to-green gradient background that had a separation at the locust branch.  The effect suggests shadows underneath the branches and a blue sky.  The background shown below is different from the final product because it lacks the gradient dynamic of the blue paint (I forgot to photograph the final background before I began detailing).

With the background complete, I was able to begin detailing the leaves and stems.  This was the most was the most time consuming aspect of the project.  I worked with oil-based paints (bright yellow and red) to create a highlighting which gives the grate a Japanese anime effect.  You can see me at work in the photos below.  (Note:  Cleaning the brushes from this oil-based paint was a chore until I learned to use acetone.  It works like a charm but gives off a lot of fumes, so be careful!)

Once my artwork was complete, I gave it one final bake in the oven just to make certain it was dry and hard.  At this point, I could have given it a coating of clear enamel, but I was too anxious to put my new creation to use.

The final phase of my project was attaching felt pads to the bottom of the stand.  This is important in protecting the wood table from the heavy plant stand.  The grate used to make the stand is cast iron and weighs a hefty 18 pounds.  I used six ½ inch diameter pads that I purchased from the local hardware store.  They also had rubber bumpers that I considered using.  I felt that the “felt” would work better for this application.

Just take a look at the finished product below!  Wowzer!!  This was a fun project.  This locust grate is available in a 20” x 40” size, as well.  I’ve seen a coffee table made from this larger locust grate.  And, I have my eye on a sun grate that looks like it would make a nice wall hanging.  It makes me wonder about how many uses there are for these ornamental grates.  Email me, Hannah@trenchdrain.biz, with your ideas if you can think of other uses for any of the Iron Age ornamental grating products.  If you have photos of something special you have done, send those, too.  I’d love to see your work.

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.
