Shipping Drywall Freight Class Guide
Drywall typically classify around Class 55, in the 30-40 lb/ft³ density range. Banded drywall sheets.

Shipping Drywall the Right Way
Weight Hits Legal Limits Fast
Drywall's density means a flatbed can reach its legal axle weight well before the trailer looks full, so load planning has to prioritize axle weight distribution over the available deck space, much like other dense building materials.
Edges Chip Before the Board Breaks
The paper-faced edges and corners of a drywall sheet are far more likely to chip or crack than the board itself is to break, so edge protection and careful strap placement matter more than raw securement strength alone.
Weather Protection Is Not Optional
Drywall's gypsum core absorbs moisture and loses structural integrity when wet, so tarping on flatbed hauls isn't just about appearance the way it can be with some building materials. A soaked bundle is often a rejected delivery.
Drywall: What Carriers and Shippers Look For
Drywall is dense, heavy, and brittle, a combination that puts it around Class 55 on the density table but makes the real shipping challenge weight distribution and edge protection rather than classification. Banded sheets ship almost exclusively on flatbed, where load securement has to account for both the bundle's significant weight and the fact that drywall's paper-faced edges chip and crack far more easily than the material's overall density would suggest.
Why Drywall Classifies Around Class 55
Banded drywall typically runs 30 to 40 pounds per cubic foot, dense enough to land most shipments around Class 55, one of the cheaper classes on the table. In practice, drywall moves almost entirely as full truckload flatbed freight rather than classified LTL, so the class figure matters mainly for documentation and the occasional partial shipment. The real cost and planning driver on drywall freight is weight, not class, since a flatbed can hit its legal axle limit with deck space still visibly unused.
Securement and Weather Protection
Drywall bundles need chain or strap securement rated for the load's actual weight, with edge protectors wherever a strap crosses a bundle corner, since unprotected straps cut into the paper facing and chip the gypsum edge underneath.
Tarping matters more for drywall than for most flatbed freight, since a wet gypsum core loses structural strength and often can't be salvaged the way rain-exposed lumber sometimes can. Carriers running drywall regularly keep tarps rated for the full load ready before departure rather than sourcing them at the dock.
Equipment and Handling Notes
Flatbed is standard for drywall, since forklift loading from the side is far more practical than trying to load banded sheets through a dry van's rear doors. Axle weight distribution deserves attention on every load, since drywall's density means even a partial flatbed can already be near its legal weight limit.
Common Shipping Mistakes
Strapping directly over unprotected bundle corners is the most common cause of edge damage, since the strap's own tension chips the gypsum and tears the paper facing at exactly the point of contact.
The second mistake is underestimating axle weight distribution on a partial load, which can put a truck over its legal limit even when the flatbed's deck still has visible open space.

“Drywall looks simple to haul until you feel how fast the axle weight adds up. I plan these loads around the scale, not the deck space.”
“I never strap drywall without corner protectors anymore. Learned that lesson after chipping a whole edge of a bundle on a short haul.”
