NDS Pro Series Channel Drains

NDS offers a line of channel drain systems called the “Pro Series”. These channels are injected, molded from polyvinyl chloride, and have a neutral slope (no slope). They come in a variety of widths (3”, 5”, 8” and 12”). According to NDS literature asterisk notes, this product is technology licensed from the Italian trench drain manufacturer First Corp.

This product line really has many options if you don’t want pre-sloped channels. From a manufacturing point of view, it makes sense.  NDS production facilities would need to stock a bunch of injection mold dies of varying depth in order to make pre-sloped channel systems  Injection mold dies are expensive!

With the Pro Series, NDS instead opted to make four channel widths to account for different flow situations.  Three of the widest products have two depths (shallow and deep channels). So, in effect, there are seven different channel options in the Pro Series.

The photo above shows three of the four width options (I didn’t show the 12” wide option). The 3” and 5” wide channels come in 40 inch lengths (1 meter).  The 8” and 12” wide channels come in 20 inch lengths (1/2 meter).

Pro Series Channels Mean a Flexible Layout

A key feature of the Pro Series trench drain product line is the ability to cut the channels to any desired size. The channels come with a “double ridged” cut line every four inches (4”) along the length of the channel. This makes it possible to trim, for instance, 8 or 12 inches from the channel in order to custom fit the drain into a tight area.

Trim the channel using a simple hand saw. By making your cut in the slot formed by the double ridges, you can easily change the length of the drain while retaining an edge that allows all the standard hardware (end caps and other channels) to be attached . There is no patching of the channel in a custom length situation.

While you can cut a channel to a specific length, specialty channels are available for making 45 and 90 degree bends in the drain.  Side outlets are available in 5” and 8” wide channels.  Another notable feature is that every channel has a bottom knockout. This gives you flexibility when it comes time to place a bottom discharge. You can place a bottom outlet wherever you want.

Pro Series Grates: Know Your Options

Grating options are not extensive with this brand and vary by channel size. For instance, the 3” wide Pro Series channel only has a gray plastic grate suitable for pedestrian or light vehicle traffic. This may be adequate for home owners that are looking for a budget driveway drain.

The 5” wide Pro Series drain, however, has the most grating options. Plastic slotted grates (class B loading) are available in six (6) colors. Perforated plastic grating is available, but only in gray. A cast iron grate and a high impact resistant plastic slotted grate are also available in 5” width.

The 8” and 12” wide Pro Series products have fewer grating options. With the 8” wide channels, you have a choice of three plastic grates, one of which is perforated, and one slotted cast iron grate. The 12” wide channel only has a plastic slotted grate (light vehicle traffic) and a cast iron grate for heavy traffic. All grates, no matter the width, come in 20 inch lengths.

One thing I like about the Pro Series product line over other NDS brands (such as the Mini or Spee-D series) is that it offers more durability and life to your drain system because of the grate to channel width relationship. I feel it is important to have your grate wider than the channel of the trench. This is particularly important in plastic trench drain products. If the grate is wider than the channel, then the concrete that surrounds the trench will be giving added strength to the channel. Systems that don’t have this added support have to rely solely on the strength of the plastic channel. In this later case, if the ledge that supports the grate breaks, the load capabilities of the grate fail. More on this when I cover other NDS channel drains.

List prices of the NDS Pro Series cover a broad spectrum. The least expensive is, of course, the 3” wide system and prices go up as do the channel widths. Grates with higher load capabilities also come at a premium.

Common Plastic Terminology for Trench Drains

It’s time to discuss some plastic terminology!

Disclaimer: I am not an organic chemist or a plastics engineer. I’m gathering this information from other sources and I may not be explaining it as accurately as I need to.

Polyolefin — is a polymer produced from a simple olefin, or alkene as a monomer. For example, polyethylene is a polyolefin produced by “polymerizing” the olefin “ethylene”. Another common polyolefin is polypropylene. I consider polyolefin a general term for a family of plastics. (http://en.wikipedia.org/wiki/polyolefin)

Polyethylene — is a semi-crystalline plastic with excellent chemical resistance, good fatigue, and wear resistance. They can have a wide range of properties which are determined by the length and degree of branching of their polymer chain. In general, polyethylenes have good resistance to organic solvents, high impact strength, are light weight, resistant to staining, and have a low moisture absorption rate. They are easy to distinguish from other plastics because they float in water. (http://en.wikipedia.org/wiki/polyethylene)

HDPE (High Density Polyethylene) — HDPE is the most common polyethylene used in industry. It offers excellent impact resistance and high tensile strength. Technically speaking, it has a low degree of branching and thus a stronger intermolecular forces. HDPE is non-toxic and meets FDA and USDA certifications for food processing. It is commonly used for the manufacturing of milk jugs, margarine tubs, detergent containers and trash cans. It is also an excellent material for use in trench drain and storm sewer pipe.

Polypropylene is an economical material that offers a combination of outstanding physical, chemical, mechanical, thermal and electrical properties not found in any other thermoplastic. It has a lower impact strength that does HDPE, but it also has better tensile strength and superior heat resistance.

Structural Foam — is a structure imparted to an olefin during processing that gives the plastic addition strength and resilience. More on this later.

PVC (Polyvinyl Chloride) — Is a widely used thermoplastic polymer. Over 50% of the PVC products manufactured are used in construction as a building material. PVC offers excellent corrosion and weather resistance and has a high strength-to-weight ratio. PVC is inexpensive, easy to clean, and a popular replacement for wood and concrete building materials. It is used in house sidings, drainage pipe, window profiles and plumbing fixtures (such as some trench drain). Despite appearing to be an ideal building material, concerns have been raised about the costs of PVC to the natural environment and human health. (http://en.wikipedia.org/wiki/polyvinyl_chloride)

Fiberglass Reinforced Polyester — Polyester is a category of condensation polymers which contain the ester functional group in their main chain. This group also includes polycarbonates. Polyesters are popular for being used as a woven fabric. When fiberglass is added to polyester, the resultant material is more durable and resistant to impact.

UV Inhibitors — These are chemical additives that are added to plastic which help to retard the damaging effects of ultraviolet light to the plastic.

Injection Molding — This is a forming method by which intricate trench drain products (or other plastic shapes) can be shaped. In this process, a heated and liquid thermoplastic is injected into a mold that contains a cavity that has the shape which is desired. Once injected with plastic, the mold and part is cooled. The resulting plastic shape is removed from the mold and trimmed of flashing (excess plastic). This method is needed to form pre-sloped trench channels. Though mold costs are expensive, one mold is required for each size of pre-sloped channel.

Extrusion — Another method of making trench channel is extrusion. In this process, a heated batch of thermoplastic is continuously injected through a water-cooled die. The shape of the die will determine the cross-section of the extruded part. This method can be used to make simple, non-complex parts such as pipe, tubes and u-shaped channels. The most inexpensive channel drain products are made using this forming method.
