Manufacturing & quality
How a Brix tarp is made.
Most tarps fail at the same places: thin material, cheap filler, weak edges and loose grommets. We make ours so those are the strongest parts. Here is every step, from raw material to the box on your doorstep.
The process
Eight steps. No shortcuts.
This is how our woven poly tarps are made. Every step is there to make the tarp stronger, thicker and the right size.
Step 01 · Material100% virgin polyethylene
It starts with new polyethylene resin, never recycled filler. Virgin material is stronger, more consistent and lasts longer in the sun.
Step 02 · TapesExtruded into strong tapes
The resin is melted, formed into film and cut into narrow tapes. Those tapes are the threads of the tarp.
Step 03 · WeavingA tight cross weave
The tapes are cross-woven into a dense fabric. A tighter weave resists rips, punctures and stretching.
Step 04 · LaminationLaminated on both sides, UV treated
Both faces of the woven core get a coating. That makes it waterproof and adds UV resistance, so it holds its color and strength outdoors. Thicker grades get more material, from 5 mil all the way to 22 mil poly.
Step 05 · HemmingPP rope sealed into the hem
The edges are folded and sealed with polypropylene rope inside, so the border holds its shape under strap tension instead of tearing.
Step 06 · Corners & grommetsReinforced corners, grommets all around the edge
Every corner gets a reinforced plastic patch, and rust-proof metal grommets are set along every edge.
Step 07 · MeasuringMeasured for finished size and thickness
The tarp is measured after hemming, so the label shows the true finished size. Thickness is checked with a digital caliper.
Step 08 · PackingFolded, labeled and shipped
Each tarp is folded and packed with its size, thickness and color on the label, then shipped from the warehouse closest to you.
Quality checks
Measured, not guessed.
A tarp is only as good as its numbers. These are the checks behind every label.
Thickness, by caliper
Thickness is measured with a digital caliper. A 20 mil tarp reads 0.51 mm and a 22 mil reads 0.56 mm. What's on the label is what's in your hands.
Finished size
Every size is measured after hemming. A 20×30 covers a true 20×30, not a few inches short on every side.
Grommet spacing
Metal grommets all around the edge, so you're never far from a tie-down point.
Weave & material
A tight cross weave of 100% virgin polyethylene, laminated on both sides for waterproofing and UV resistance.

FAQ
Quality questions.
Why does virgin polyethylene matter?
Recycled filler makes a tarp weaker and less consistent, and it breaks down faster in the sun. Virgin material keeps its strength, color and flexibility longer.
What does weave count mean?
It's the number of tapes per inch in each direction, for example 14×14. A tighter weave makes a stronger, more tear-resistant core. Each product page lists its own specs.
Why rope in the hem?
The rope carries the pull from tie-downs along the whole edge, so the hem doesn't stretch or rip at the grommets.
What's the difference between mil, oz and GSM?
Mil measures thickness (1 mil = 0.001″) for poly and vinyl. Ounces and GSM measure weight per area, for canvas, mesh and fence screens. See the thickness guide →
