Flatbed Strap Placement & Edge Protection (2026)
The strap that causes the claim usually looked fine from the ground. It was sitting on a bare edge, crossing the load at the wrong angle or cranked hard enough to crush the product. OpenDeck, powered by Load Work, covers flatbed strap placement, edge protection and tension for 2026, whether the freight comes from flatbed load boards or a repeat shipper.
TL;DR
One edge board under every strap - the strap never touches bare product.
FMCSA rules require tie-downs at least every 10 feet of cargo length, minimum two per load.
Aggregate working load limit must cover at least half the load's weight.
Angle straps down over the load; never run them across a bare corner.
Re-tension every strap after the first 50 miles and at every stop.
A tight strap can still be in the wrong place
Straps hold freight down and fight movement under braking. The angle decides how well they do either job. Run one flat across the top of a tall stack and the load can still lean in a hard lane change. Drop it into a V and the same strap works against the tip.
A poor setup shows up fast: a truck-stop rework, a late delivery or a strap mark across finished steel. None of those pays.
Place straps by cargo length, not by habit
The federal rule is the starting point, not the target.
Place tie-downs at least every 10 feet of cargo length - and closer on freight that walks, like bundled pipe or palletized drywall
Run a minimum of two tie-downs on any load, no matter how short
Add one strap per pallet row or bundle cluster rather than one strap spanning several rows
Catch the front and rear of every load with their own straps - the first and last feet of freight move the most
On loads over 10 feet but shorter than a full deck, do not split the difference with fewer straps; add the extra one
Aggregate working load limit must equal at least half the cargo weight. Count the stamped WLL on every strap, not the breaking strength on the box.
Angle the strap to the freight shape
The geometry of the strap does more work than the ratchet.
Run straps down and over the load at an angle, never straight across the top of a tall stack
Cross straps front-to-rear in a V over long freight like pipe or lumber to fight forward creep under braking
Keep straps off bare corners of crates, coils and pallet edges - angle them into dunnage gaps or over edge boards
On coil and pipe, run straps through or around the freight so it cannot roll out of its cradle
On stacked drywall and lumber, strap over the stack at each dunnage gap so pressure spreads across the whole bundle
Edge protection is not optional
The most common flatbed damage claim is self-inflicted: a strap sawed through product it was supposed to protect.
Run plastic or wood edge boards under every strap that touches freight
Use corner protectors where straps cross crate corners or stacked sheet edges
Pad banding on shingle bundles - a ratchet strap sawing on plastic banding cuts it in one bind
Never let a strap contact bare gypsum, finished steel or crate skids directly
Re-check edge boards at every stop - a board that slid out from under a strap leaves the strap cutting bare product
Edge boards cost a few dollars. The claim they prevent costs the whole load's margin.
Set tension without tearing anything
Ratchet straps hold at working tension, not maximum torque.
Snug the ratchet until the strap is taut and the webbing stops moving - not until it creaks
Overtension crushes product, stretches webbing past its rating and bends the ratchet handle
A strap that hums when you pluck it is tensioned; a strap that thuds is loose
Re-tension every strap after the first 50 miles - new webbing stretches and settles
Retire any strap with cut, frayed or UV-chalked webbing; a damaged strap is a liability, not gear
Match the securement to the commodity
Different freight moves differently on the deck.
Bundled lumber and pipe roll - strap in V-patterns and add belly wraps under the stack
Palletized roofing and drywall shift as a unit - strap each pallet row separately
Crated machinery rocks - strap over the crate top with corner protection and block the skid
Steel plate and bar stock slide - run direct chains or high-angle straps at the front and rear of the bundle
For the chain side of that math - when a strap stops being the right tool and working load limit takes over - the WLL math and tie-down rules live in machinery securement on a step deck. And for the tarp work that goes over the straps on steel, lumber and machinery freight, the throw sequence lives in flatbed tarping for steel, lumber and machinery.
The verdict: place straps by cargo length and freight shape, angle them into the load, protect every contact point, and re-tension at the first stop.
Common mistakes drivers make with strap placement
Strapping over bare product - one ratchet pull across a bare drywall edge or finished steel buys a refused load and a claim against you.
One strap over the whole load - a single strap spanning four pallet rows holds none of them; each row needs its own tie-down.
Straight straps over tall stacks - a strap run flat across the top lets the freight tip sideways in a lane change; angle it down into the dunnage gaps.
Trusting breaking strength over WLL - a 4-inch strap rated at 5,400 pounds of working load limit is not a 15,000-pound tie-down, and inspectors read the tag.
Skipping the 50-mile re-tension - new webbing stretches, banding settles, and the load you set at the dock is not the load you have at mile 100.
OpenDeck, powered by Load Work, filters open-deck freight by trailer type, weight and length. Securement still has to be confirmed with the broker before you book.

FAQ
How far apart should straps be on a flatbed load?
FMCSA rules require tie-downs at least every 10 feet of cargo length, with a minimum of two per load. Loads that walk, like pipe and palletized freight, need straps closer than 10 feet.
How tight should I ratchet a strap?
Snug the webbing until it stops moving and hums when plucked - not until it creaks. Overtension crushes product and stretches webbing past its working rating.
Do I need edge protection under every strap?
Yes, wherever a strap touches freight. Plastic or wood edge boards under every contact point stop the strap from sawing into product, which is the most common self-inflicted flatbed claim.
What is the working load limit rule for flatbed straps?
The aggregate working load limit of all tie-downs must be at least half the cargo weight. Count the stamped WLL on each strap, not the breaking strength printed on the packaging.
How many straps does a 48-foot load of lumber need?
At minimum one tie-down every 10 feet - five for a full deck - but stacked lumber that rolls or shifts rides better with V-pattern straps and belly wraps under the stack in addition to the base count.
When should I re-tension straps on a flatbed load?
After the first 50 miles, then at every fuel stop. New webbing stretches and settles fast, and a strap that was taut at the dock is loose by mile 100.
Can I use a damaged strap if the fraying looks minor?
No. Cut, frayed or UV-chalked webbing retires the strap on the spot. A failed strap under tension is a liability, not gear - and inspectors write it up on sight.
Boards first, straps second
The edge board does no good in the side box. Put protection at every contact point before the webbing goes over the load. Then set the angle. Tension comes last.
