Dura Trench is the first USA company to manufacture a pre-sloped curved channel drain.  We offer our curved drainage channels in any radius, width, depth, and slope.  Our curved channel drains are fully customizable and really make a statement for the perfect look.  We also manufacture curved slot drain.  Our curved slot drains hide away and are practically invisible.  We offer our curved slot drains in any radius, diameter, depth, and slope.

A curved channel drain or curved slot drain has several components that must be considered.  First, the curved channel drain body size must be selected.  The body should be sized for flow and debris loading.  We manufacture the channel drain body out of fiber reinforced polymer concrete.  This makes an extremely durable and corrosion resistant channel drain body that won't break or chip.  The interior of the curved channel drain is smooth not segmented.  The sections are typically 8 foot long but will vary with the radius selected.  We pre-assemble all our curved channel drains to ensure proper fit and radius dimensions.  The curved channel drains also have a 2" female receiving flange that can be used to seal the drains water tight. This is important in fountain applications.  Our curved slot drains have the same features and are built from the same materials as our curved channel drains.

 

We make curved channel drains in the following widths: 2" curved channel drain, 4" curved channel drain, 6" curved channel drain, 8" curved channel drain, 10" curved channel drain, 12" curved channel drain, 18" curved channel drain, and 24" curved channel drain.

We make curved slot drains in the following widths: 4" curved slot drain, 6" curved slot drain, 8" curved slot drain, 10" curved slot drain.  Other sizes of curved slot drain are possible simply contact our engineers for design assistance.

The next feature that must be selected is the frame for the curved channel drain.  We curve these to the exact radius required for you curved channel drain or curved slot drain.  For our curved channel drains we offer frames in epoxy coated steel, galvanized steel, and stainless steel.  We can produce a plastic frame for some radius applications if the radius is larger than about 35 feet.  For our curved slot drains we offer two styles of frames.  The first is a medium duty frame that can be used when your curved slot drain is being used next to a wall or has paving stones around it.  These frames are less visible but not as strong.  If your curved slot drain will have traffic on it, we recommend our heavy duty frame.  It is more visible but extremely strong.  Our curved slot drain frames are offered in epoxy coated steel, galvanized steel, stainless steel, and aluminum.

Finally, if you are using a curved channel drain you must consider the grate on the top.  A true curved trench drain grate must be made to match your exact radius for that smooth look.  We manufacture these curved channel drain grates in all types of materials, finishes, patterns, and load ratings.  Radius grates can be fully customized to meet your every need.  We also offer several standard curved channel drain grates to meet the needs of customers that are in a hurry.  Contact your local sales rep to help you with your radius grating selection.
