PVC / PVDF

PVC and PVDF fabric options

PVDF commonly describes a surface finish over PVC-coated polyester. We specify the full fabric construction and model for each order.

01 / PVC

PVC-coated polyester fabric

Architectural fabric often combines a polyester base cloth with a PVC coating for flexibility, waterproofing and fabrication. Strength, translucency, colour and weathering depend on the exact product.

Read the selection guide →

02 / PVDF

PVDF surface-finished fabric

In architectural fabric, “PVDF membrane” usually refers to PVC-coated polyester with a PVDF surface finish. The finish can help resist soiling and ease cleaning. Specific performance depends on the selected product.

FABRIC SPECIFICATIONS

Nine PVC and PVDF specification rows

All nine rows are retained for comparison. Our regular project range starts at 1050 g/m²; lighter grades require a separate suitability review. Compare weight and tensile strength first, with thickness as supplementary information.

For carports, walkways and landscape canopies, we normally start at 1050 g/m². The 750, 950 and 1000 g/m² rows remain for comparison and are not regular project starting grades. Check site loads, fabric condition and the exact product before any separate selection.

“Flame-retardant additive” is not a B1 or B2 classification. Table values and service-life figures support early model selection under normal installation, use and maintenance; confirm final performance against the chosen product documents.

PROJECT-SPECIFIC FABRICATION

ETFE and PTFE can be customised by project

Send the drawings and intended use. We can discuss ETFE film or cushion systems and PTFE-coated glass fabric, then confirm panel layout, connections, material documents and the fabrication or installation scope for the project.

ETFE / FILMPROJECT CUSTOMISATION

Custom ETFE film and cushions

For daylight roofs, atria and façades, we can plan panel divisions, light transmission, form and connection details from your drawings. Inflated cushions also need an agreed air-supply, sealing and maintenance plan; supply and installation scope are confirmed for each project.

PTFE / GLASS FABRICPROJECT CUSTOMISATION

Custom PTFE-coated glass fabric

For stands, transport hubs and other long-span roofs, we can discuss fabric model, panel geometry, seams and edge connections against the design. Fire and weathering performance must be checked against the selected product documents before confirming the fabrication scope.

CUSTOM FABRICATION

How custom fabric orders work

Our Xingyang workshop works from your project requirements, drawings and material specifications for orders across China.

Select for the use

Carports, landscape roofs, grandstands and walkway canopies have different daylight, drainage, structural and maintenance requirements.

Specify the fabric

Discuss colours, graphics, weight, roll width, translucency, surface finish and fire requirements; confirm the selected material and samples.

Fabricate to drawings

Check panel layout, cutting direction, seams and edge connections. Drawings, samples and dimensions need version control.

Agree the delivery

Record model, batch, test documents, fabrication scope, packing, transport and installation interfaces.

FIRE PERFORMANCE

How to review B1 and other fire indicators

Under GB 8624, B1 denotes a difficult-to-burn building material. The listed high-strength PVDF 1100 and 1250 g/m² options carry a B1 notation. For approval, match the actual product with its applicable classification report.

B1 alone does not promise non-combustibility, no toxic smoke, no flaming droplets or instant self-extinguishing. Review the smoke (s), flaming-droplet (d), toxicity (t) and any additional tests requested by the project.

ANon-combustibleB1Difficult to burnB2CombustibleB3Easily combustible

Six points to check for a fire-sensitive project

The exact tests and numerical results depend on the selected product and the project specification.

Ignition and flame spread

Ignition depends on the heat source, exposure time and fabric build-up. A single “ignition temperature” cannot replace test results for ignition, flame spread and heat release.

Smoke and toxicity

Review the s class for smoke production and the t class for smoke toxicity. B1 does not mean smoke-free or non-toxic combustion.

Flaming droplets

The d class describes flaming droplets or particles. Where vehicles, equipment or goods sit below the roof, check the risk of secondary ignition.

Droplet composition

The d class does not establish that molten droplets are non-toxic. Review material data or additional testing if the project calls for this.

Afterflame time

The period of flaming after the heat source is removed belongs to the applicable test method. An on-site lighter demonstration cannot replace a B1 classification report.

Oxygen index

This is the lowest oxygen concentration that sustains burning in a specified oxygen–nitrogen test mixture. It is not ambient “oxygen saturation” and does not by itself establish B1.

SERVICE LIFE

How long can membrane fabric last?

Short answer: The 6 listed PVC/PVDF grades offer indicative 10–18-year selection figures: about 10 years for PVC 1050 g/m²; about 15 years for PVDF 1100 g/m², PVDF 1200 g/m², High-strength PVDF 1100 g/m²; about 18 years for High-strength PVDF 1250 g/m². These assume design-compliant installation, normal use and regular maintenance. Actual performance varies with sunlight, climate, structural design and site conditions.

Six factors that shape service life

The same fabric can age very differently from one site to another. Each factor comes with how we address it.

Sunlight and UV

Prolonged UV exposure gradually ages the coating, especially at high-altitude and low-latitude sites.

Our approachIn strong sunlight, compare PVDF finishes and higher grades first.

Temperature and climate

Heat, severe cold, freeze–thaw cycles, coastal salt spray and humid heat all affect the coating and base cloth over time.

Our approachCheck weathering data and steel corrosion protection against the local climate.

Wind, snow and tension

Low pretension or concentrated stresses lead to wrinkles, ponding and fatigue.

Our approachVerify the structure for local wind and snow loads; check tension after installation.

Drainage and ponding

Shallow slopes or blocked drainage create water pockets that add load and collect dirt and stains.

Our approachDesign adequate slopes and drainage paths; avoid large flat areas.

Pollution and soiling

Industrial dust, cooking fumes, acid rain and bird droppings dull the surface, reduce light transmission and speed up ageing.

Our approachIn polluted settings, choose a PVDF finish and clean more often.

Fabrication and installation

Welded-seam quality, cutting direction, edge cables, clamps and steel corrosion protection all shape durability.

Our approachCheck seams, cutting and details against drawings; inspect on delivery.

Maintenance schedule

Suggested intervals; adjust for dust, sunlight and use on site.

Suggested membrane fabric maintenance schedule
Task	When	What to do
Routine checks	Ongoing	Look for damage, ponding and debris on the fabric; keep drains and gutters clear of leaves.
Cleaning	Every 3–6 months suggested	Use water or a neutral detergent with a soft brush or cloth. Avoid strong acids or alkalis, sharp tools and close-range pressure washing.
Annual inspection	Once a year suggested	Check seams, edge cables, clamp plates, bolt tightness and steel corrosion protection; re-tension slack fabric and touch up rust.
After severe weather	After strong wind, heavy rain or snow	Clear snow and ponding promptly and check for tears or loose fittings. Keep the area below out of use until issues are fixed.

Repair or replace?

Judge by how widespread the damage is and the overall condition of the fabric.

Repair

Local repair is enough

When problems are local and the rest of the fabric is sound, a repair restores it to service.

Local scratches, small holes or punctures
An opened seam or worn corner
Local stains or mould that need professional cleaning

Replace

Assess for replacement

These signs show the fabric has aged overall; repeated repairs are neither economical nor safe.

Widespread chalking, cracking or coating loss exposing the base cloth
Leaks in several places, or repeated repairs in one area
Obvious slack that can no longer be re-tensioned
Tears under light pulling, showing a clear loss of strength

REFERENCE CONDITIONS

When the reference service life applies

Installed to the design, with the structure and fabric tensioned as specified
Normal use, with cleaning, inspection and maintenance as recommended on this page
No man-made damage: scratching, puncturing, impact, climbing or hanging heavy loads, open flame or heat, or unauthorised structural changes
No extreme natural events: typhoons, snowstorms, hail, floods or earthquakes beyond design standards, or fire and lightning strikes
No prolonged contact with strong acids, alkalis, organic solvents or other corrosive agents

The 10, 15 and 18-year figures compare fabric models under the installation, use and maintenance conditions above. They do not mean a project will necessarily last that long. Actual performance also depends on local sunlight, climate, structural design, installation quality and upkeep.

FAQ

Common questions

What is the difference between PVC and PVDF fabric?

PVC generally describes the coating over a polyester base cloth. In this context PVDF commonly describes an additional surface finish. Compare the complete composition and exact product documents.

Which PVC and PVDF fabric weights are listed?

The comparison retains nine rows: PVC 750, 1000 and 1050 g/m²; PVDF 950, 1100 and 1200 g/m²; and high-strength PVDF 1100 and 1250 g/m², including a second PVDF 1100 fire configuration. Our regular project range starts at 1050 g/m². Lighter grades are retained for comparison and need a separate suitability assessment. Check the exact model and report for B1.

Can membrane fabric colours and graphics be customised?

Yes. Send a target colour code, colour card or physical sample for colour matching, and artwork, logo dimensions and placement for graphics. The final colour, printing method and appearance are confirmed against the selected fabric and approved sample.

Does B1 mean self-extinguishing, non-toxic and no flaming droplets?

B1 is the difficult-to-burn building-material class. It does not by itself establish afterflame time, smoke toxicity or flaming-droplet performance. Check the selected model’s applicable fire report, including s (smoke), d (flaming droplets) and t (smoke toxicity) classifications. An added flame retardant is not itself a B1 or B2 rating.

How is ETFE different from PVC/PVDF fabric?

ETFE is a film used in single-layer and inflated-cushion systems for roofs and façades. PVC/PVDF architectural membrane is typically coated woven fabric. Their connections, support systems and maintenance requirements differ.

How long can PVC or PVDF architectural fabric last?

The listed models give an indicative 10–18 year selection range: about 10 years for PVC 1050 g/m², 15 years for PVDF 1100/1200 and high-strength PVDF 1100 g/m², and 18 years for high-strength PVDF 1250 g/m². These figures assume design-compliant installation, normal use and regular maintenance. Local exposure and site conditions affect actual performance.

How should I read the reference service life?

It is a model-based comparison figure under the installation, use and maintenance conditions listed here. Local climate, structural design and upkeep affect how a specific project performs in service.

When does membrane fabric need replacing?

Local scratches, small holes or an opened seam can usually be patched. Widespread chalking, cracking or coating loss exposing the base cloth, leaks in several places or repeated repairs, slack that cannot be re-tensioned, or tearing under light pulling are signs to assess full replacement.

How should membrane fabric be maintained to last longer?

Clean the surface regularly with water or a neutral detergent and a soft brush, avoiding strong solvents and sharp tools. Inspect after strong wind, heavy rain or snow, clear snow and ponding, check tension, fittings and seams, and repair minor damage early.

Can we order fabric fabrication without a complete structure?

Send drawings, dimensions, quantity and material requirements to discuss a fabric-only order. Engineering, fittings, transport and installation scope are agreed for each order.
