PLANK COUNT

PolyCleat flooring measures a full 8” wide, is 1 ½” - 1 5/8” tall (not including the cleat), and comes in two standard lengths, 78.5” and 96”.

Note: the trailer in our example is 6’ x 24’. If you know your trailer dimensions, there is a calculator at the bottom of this page.

1. What plank length should you order?

We offer planks in two lengths:

• 8” (wide) x 78.5” (6 feet 6 ½ inch) (long)

• 8” (wide) x 96” (8 feet) (long)

 The 78.5” long plank will fit trailers up to 80” wide. Over 80” will require the 96” plank. Planks can be both cut to length and ripped using standard woodworking tools.

 To determine the length of boards you’ll need, multiply your width by 12”  

• For this example, you have a 6’ wide trailer

• 6’ x 12” = 72” wide = you’ll need 78.5” planks - Dimension A

2. How many planks should you order?

Note: Since every trailer has a different amount/width of steel plates, determining how many planks to order has a couple of steps. There is a diagram and calculator at the bottom for reference.

1. First, convert your trailer length to inches. Multiply the length (in feet) of your trailer by 12” to get the total number of inches - Dimension B

   • In this example, you have a 24’ long trailer

     • 24’ x 12” = 288” - Dimension B

2. Next, subtract the total number of inches of metal bracing you will NOT need to cover - Dimension C

   • Note: The amount of metal bracing is the largest variable for all trailers

   • For this example, we’ll say you have 3 steel plates, each 9” wide

     • 3 x 9” plates = 27” - Dimension C

3. This means the length of your trailer, minus any metal bracing becomes the actual area you need to cover.

   • Length of actual coverage area

     • 288” (B) – 27” (C) = 261” of total coverage required - Dimension D

4.  Our planks are a full 8” wide, so if you are going to leave a gap between planks, add the gap dimension to 8” to get the coverage per plank – Dimension E

   • For this example, we are going to use a ½” gap between planks

     • 8” plank + ½” gap = 8.5” - Dimension E

5. Finally, divide your coverage area needed (Dimension D) by the coverage per plank (Dimension E) to determine the total number of planks required

   • The total number of planks required for this trailer

     • 261” (D) ÷ 8.5” (E) = 30.71 planks (rounded up) = 31 planks

So for the 6’ x 24’ trailer in this example, you would order a minimum of 31 - 78.5” planks.
