Installation Tips
A 12” - 16” span (or less) between support framing under the planks is recommended; a span over 16” is not recommended.
If you want to leave a gap between planks, the distance can range from .25”- 1”. A 1/2” gap is the most common, but it is completely up to you and your state regulations.
When cutting each plank to length, we recommend leaving a ½” to ¾” gap next to the sidewall on each side of the trailer to facilitate the cleanout of manure and mud under the planks.
Always drill a pilot hole and use self-tapping screws - 1/4” x 2 ½” (diameter x length).
You will need a minimum of seven screws per plank. Two self-tapping trailer flooring screws are needed at each sidewall, and an additional three screws along the plank are also recommended to help control movement. You can use more screws than this if you prefer; seven is the minimum we recommend.
If you desire a more durable fastening option, you can opt for galvanized screws, stainless steel screws, or 1/4" stove bolts with a self-locking nut.
(Note: the type of screws pictured in the photo below are for alignment demonstration only)
Screw alignment is very important. You must catch the full height of the plank with the screw. Use the groove lines (see photo below) on the upper sides of the planks as a placement guide to drill pilot holes through the plank and framing before driving the screws.
IMPORTANT: The screws fastening the plank down MUST pass through one of the legs on the underside of the plank. If not secured through the bottom legs (see photo below), the screw head may pull through the plank.
There may be odd 4” or 6” spaces between a full plank and the next steel plate. To ensure full coverage between plates, you can rip boards lengthwise with any standard woodworking tool.
IMPORTANT: If you rip a plank to fit an odd space, make sure you have at least two remaining underside/bottom legs. (see photo below)
You may consider ordering an additional plank to ensure you can complete the installation.
If you have any small bits of plank left over at the end of the project, they make great stepping stones.
