Lumber tarps, specified in writing before you pay

A flatbed trailer in a timber yard loaded with banded packs of dimensional lumber, a tarp drawn over the top of the load and reaching partway down the stack.

In short. A lumber tarp fails at the spec nobody wrote down: 16 oz sold as heavy duty, a 6 ft drop where the load needed 8, grommets that pull out mid-winter. We write the specification first, you approve it, and the delivery is checked against it line by line.

What must be on the written spec

  • Fabric weight (the 16 oz vs 18 oz trap)
  • Drop height, 6 ft vs 8 ft
  • End flap placement
  • Grommet density
  • Reinforcements and panel seams
  • D-ring rows
Drop height against an 8 ft loadTwo flatbed loads of identical height, 8 ft. Under a 6 ft drop the tarp stops 2 ft above the deck and the bottom of the load stays uncovered. Under an 8 ft drop the same load is covered down to the deck. 6 ft drop the published lumber format, on an 8 ft load 6 ft 2 ft left bare 8 ft drop same load, covered to the deck 8 ft
The vertical scale is real: the load is 8 ft in both rows, and a 6 ft drop leaves exactly 2 ft of it uncovered. Published lumber formats carry a 6 ft drop flap, which is why load height belongs on the written spec before anything is ordered.

Questions fleets actually ask

What is the difference between a 6 ft and an 8 ft drop?

The drop is how far the tarp hangs down the sides of the load. Published lumber formats carry a 6 ft drop flap; taller loads need 8 ft, and a short drop leaves the bottom boards exposed to road spray. State your usual load height on the quote and the drop is confirmed in writing, not assumed.

Why does 16 oz vs 18 oz matter so much?

Ten years of practitioner threads document the same failure: fabric under 16 oz lets water through, and the difference is invisible on delivery day. The published 18 oz reference values are measurable: grab tensile 450 x 425 lbs (ASTM D751), coating adhesion 10 lbs/in. The reception check is a scale on a cutting, and we put that check on the order.

How heavy is a lumber tarp?

A published reference: 94 lbs (43 kg) for a 20x27 ft in 18 oz with a 6 ft drop (US retail listing, August 2026). That weight is also a reception check: a finished tarp far under it was not cut from 18 oz fabric.

Which sizes can you quote?

The formats published by US vendors are 20x27 and 20x28; factories quote custom dimensions on request. We only quote against a written dimension sheet: flat size, drop, flap placement. If a dimension is missing, we ask before we quote, we never fill it in.
