Four roll sizes cover most scaffold work — 4'×50' for guardrail runs, 5'6"×150' for partial lifts, 8'6"×150' as the full-lift standard, 2×50 m and 3×50 m in metric markets. Match width to the lift, mesh to the dust, GSM to the reuse count.
Scaffold netting is sold by the roll, and the roll size you order decides how much of the job goes smoothly: too narrow and your crew stitches seams all week, too wide and you pay for fabric that hangs past the ties. The good news is that four sizes cover most frame-scaffold and facade work: 4’×50′ for guardrail-height runs and small jobs, 5’6″×150′ for partial lifts, and 8’6″×150′ as the full-lift standard (2×50 m and 3×50 m in metric markets). This guide matches roll size to scaffold type, mesh opening to the work happening behind it, and GSM to how many projects the roll has to survive.
| Roll size | Coverage per roll | Typical job |
|---|---|---|
| 4′ × 50′ (1.2 × 15 m) | ~19 m² | Guardrail-height runs, small repairs, short frontages |
| 5’6″ × 150′ (1.7 × 46 m) | ~77 m² | Partial lifts, sidewalk sheds, renovation fronts |
| 8’6″ × 150′ (2.6 × 46 m) | ~118 m² | The full-lift standard for frame scaffolding — one roll covers a lift with tie-off overlap |
| 2 × 50 m / 3 × 50 m (metric) | 100 / 150 m² | EU and Middle East scaffolding, bought by the meter |
The pattern behind the numbers: rolls come in short-and-narrow or long-and-wide, because the two buying situations are different. Contractors patching a small frontage want a roll two people can carry and hang in a morning. Contractors wrapping a multi-story frame want the longest roll that still matches their lift height, so the crew ties once per lift and moves on.
The width question is really a lift question. Standard frame-scaffold lifts run about 6’4″–6’6″ per level; an 8’6″ roll covers the lift plus the overlap you need to tie top and bottom rails without a seam. That overlap is not waste — it is what keeps the net taut and the gap between lifts closed, and an open horizontal gap is exactly where debris escapes. On tube-and-clamp or system scaffolds with non-standard bay heights, measure the lift first and order the width to it; guessing from the facade height is how crews end up with a 2-foot gap at every level. For metric frames, the 2 m and 3 m rolls play the same role: pick the one that spans your lift with tie-off margin.
Roll size decides coverage; mesh opening decides containment. The industry-standard split: 1/4″ mesh for general construction debris — tools, offcuts, packaging, the everyday facade work — and 1/16″ mesh when the work behind the net produces fine particles: sandblasting, grinding, masonry cutting, stucco. Tighter mesh catches more dust but also catches more wind, so a 1/16″ enclosure on a tall exposed frame needs closer tie spacing and an honest look at wind load. When the spec document says nothing about particle size, 1/4″ is the default that contractors reorder.
Weight is the durability dial. Our scaffolding net range runs 85/90/100/110/120 gsm in 100% virgin HDPE with UV stabilization:
If the net will move between projects, buy by reuse cycles, not by the cheapest roll — a 120 gsm roll that survives three jobs costs less per facade than three 85 gsm rolls. And one boundary that is not negotiable: scaffold debris netting is containment mesh, not fall protection. Personnel safety netting is certified life-safety equipment; debris mesh must never be substituted for it, whatever the GSM.
A 40’HQ carries 14–15 tons of knitted netting, and what that means in rolls depends on GSM and roll format. Working from the four standard sizes:
| GSM | Approx. m² per container | 8’6″×150′ rolls (~118 m²) |
|---|---|---|
| 85 | 165,000–176,000 m² | ~1,400–1,490 rolls |
| 100 | 140,000–150,000 m² | ~1,180–1,270 rolls |
| 120 | 117,000–125,000 m² | ~990–1,060 rolls |
Two things distributors notice in this table. First, GSM moves roll count more than most buyers expect — a container of 85 gsm holds about 40% more rolls than the same container at 120 gsm. Second, mixed containers are how yards actually stock: a typical first order combines the three widths across two GSM grades, which our 2-ton MOQ accommodates inside a single shipment.
OMB Textiles is a knitted HDPE netting manufacturer in Changzhou, China — founded in 2003, knitting scaffold and debris netting on our own warp-knitting lines for construction distributors and contractors worldwide. The practical bulk terms: roll sizes beyond the four standards are a production setting, not a surcharge — tell us your frame lift height and we knit the width to it. Colors run to the high-visibility green, blue and orange that site specs ask for, and fire-retardant grades ship with the batch test report (the FR decision is covered in our NFPA 701 fire-retardant guide). MOQ is 2 tons with mixed widths, GSM and colors in one container; a 40’HQ carries 14–15 tons, roughly 130,000–150,000 m² at 100 gsm. Production runs 25–35 days after deposit; samples are free, you cover the courier. Send your frame type, lift height, total linear meters and destination port via the contact page or WhatsApp — we reply within 24 hours with roll counts and a loading plan. The full grade range is on the scaffolding net product page, and the containment-vs-safety distinction is detailed in the debris netting safety guide.
8’6″×150′ for most frame systems — it spans a standard ~6’6″ lift with overlap for top and bottom ties. Use 4’×50′ for guardrail-height runs and small jobs, and measure your actual lift height before ordering if you run system or tube-and-clamp frames.
Divide the facade area by the roll’s coverage, then add 10–15% for overlap and trimming. Example: a 100 m × 20 m facade is 2,000 m²; an 8’6″×150′ roll covers ~118 m², so you need about 17 rolls plus margin — call it 20. We run this math for your dimensions when you send an inquiry.
If hot work (welding, grinding, cutting) happens behind the net, or the project spec or local code calls for it, yes. FR grades cost more per roll and are worth it exactly there; for general debris containment with no ignition sources, standard UV-stabilized HDPE is the normal buy.
Yes, if you buy for it. Knitted HDPE does not fray when cut, and 100–120 gsm rolls survive teardown, re-rolling and redeployment with reasonable handling. Reuse fleets should also spec reinforced edges and store rolls dry and out of sunlight between jobs.
Yes — width, length, GSM and color are production settings for us. Distributors commonly mix the four standard sizes plus a custom width in one container so their yard stocks every frame type their customers run.
