Flexible materials · drawing-based supplyClear Tarp with Grommets
Keep the view. Get the fixing details right.
Source clear vinyl material and custom finished tarp panels from DERFLEX for patio enclosures, industrial partitions and OEM cover programs. A successful panel needs more than a thickness label: the finished size, reinforced border, hole positions and support frame must work together.
Send your opening dimensions, a frame photo and required quantity. Define the clear viewing area and fastening layout before approving the material and production drawing.
Order the finished panel, not just a sheet size
A listing described as a “10 × 12 clear tarp” may refer to material before hemming or to the finished outside size. For a custom installation, state the measurement basis explicitly. A border also reduces the transparent opening, even when the overall panel fits.
| Item | Define on the order | Why it matters |
|---|---|---|
| Supply format | Material roll, cut sheet or finished grommeted panel | Roll goods do not include fabrication or mounting hardware. |
| Clear panel | PVC grade, nominal thickness, tolerance and approved appearance | Clarity, flexibility and surface condition require a sample reference. |
| Finished dimensions | Outside width × height, units, viewing side and tolerance | Separates the delivered panel from the opening and raw cut size. |
| Reinforced border | Construction, border width, color and corner detail | Defines the load path around holes and the remaining viewing area. |
| Grommets / eyelets | Material or finish, clear internal diameter, hole offset and positions | The hole must accept the intended hook, tie or fastener. |
| Seams and access | Seam positions, overlaps and any requested access opening | A seam can affect visibility; an opening changes the edge detail. |
| Exposure and packing | Indoor/outdoor duty, temperature, handling and roll/fold preference | These conditions influence grade selection and delivery appearance. |
On small screens, swipe inside the table to compare all columns.
Use the broader clear tarp product range for material options, or review custom tarps made to a drawing when the panel includes access features or a nonrectangular shape.
Make every fixing point unambiguous
Measure the supporting structure first. Record the clear opening, the available mounting face and the position of existing fixings. Do not automatically add the same allowance to all four edges: overlaps, access and hardware may require different details on each side.
Start from one labeled corner
State whether the drawing is viewed from inside or outside. Use the top-left finished corner as a datum, then locate hole centers with X and Y measurements. Specify which edges have grommets and identify any corners with a different detail.
If holes must match existing bolts, individual coordinates are more useful than “approximately every 24 inches.” Include the permitted positional tolerance in the approved drawing.
Separate spacing from edge offset
Center-to-center spacing is the distance between adjacent holes. Edge offset is the distance from the finished edge to the hole center. Neither dimension defines the grommet's internal diameter or the width of its metal flange.
Check the complete hardware envelope against the border, seam and corner patch. A correctly sized hole can still be difficult to use when it is too close to an obstruction.
Geometry example only: With a 2,000 mm finished edge and hole centers 50 mm from each end, the end-to-end center span is 1,900 mm. Five equal intervals give 380 mm spacing and six hole centers on that edge. This arithmetic does not select an appropriate load-bearing spacing; shared corner holes must be counted once in a full-panel schedule.
Compare 20 mil and 30 mil without overlooking the border
Thickness describes the sheet, while “heavy duty” is a broad sales description. Compare clear vinyl samples for handling, appearance and the required service environment, then assess the reinforced edge and attachment assembly. Thickness alone cannot establish resistance to grommet pull-out.
| Thickness label | Exact conversion | Review with the sample |
|---|---|---|
| 20 mil | 0.508 mm | Handling flexibility, hanging behavior, visual appearance and edge support. |
| 30 mil | 0.762 mm | Added material and panel weight, rolling/folding behavior and mounting demand. |
One mil is 0.001 inch, or 0.0254 mm. GSM measures mass per area and cannot be converted directly to mil without the material construction and density. Request a grade-specific specification and tolerance rather than treating a familiar retail thickness as an approved production standard.
Smooth clear PVC / vinyl
Consider this construction when the view through the panel matters. Approve haze, tint, surface marks and the appearance of any welded joint under the lighting expected at the installation. Flexible clear sheet can show reflections and wrinkles; it is not rigid glazing.
Review super clear PVC film for the material itself and clear PVC tarp fabrication options for the finished-panel discussion.
Reinforced transparent alternatives
A visible scrim or grid changes both appearance and construction. Decide whether an unobstructed view or a reinforced sheet is the priority before comparing products. Different materials require their own joining and edge details.
For the material-family distinction, see the guide to clear plastic tarp types. An opaque PVC tarpaulin may suit a border or cover section when visibility is unnecessary.
The reinforced edge is part of the product
Specify the edge assembly
A grommet reinforces a hole; it does not strengthen the whole sheet. Discuss the proposed hem, compatible border material, webbing or local patch arrangement with DERFLEX. The agreed construction should show how the fastening force reaches a wider part of the panel.
Keep corner reinforcement, welds and hole placement on the same drawing. Where a seam meets a border, evaluate the completed assembly rather than approving the sheet and hardware separately.
Match the hole to its connector
Provide the hook, cord, turn fastener or other mating hardware dimension. Record the usable hole diameter and attachment clearance. Specify the required metal or finish for the environment instead of using “rustproof” as an undefined requirement.
If zippers, pockets or alternative fixing interfaces are needed, identify their position and function. Confirm which accessories are included in the quotation; frame, anchors and installation are separate scope items unless expressly agreed.
Choose the panel around its installation
Clear grommeted panels are useful when a flexible barrier must retain daylight or line of sight. Each application brings a different balance of visibility, support, access and exposure.
| Application | First priority | Detail to resolve |
|---|---|---|
| Patio or restaurant enclosure | Appearance, clear viewing area and access | Frame fixing positions, rain overlaps, removable panels and exposure. |
| Industrial partition | Visibility and operational access | Suspension interface, abrasion zones and any documented fire requirement. |
| Greenhouse side panel | Light needs, ventilation and support | Grade-specific optical data if required, drainage and seasonal handling. |
| Equipment inspection cover | Viewing location and access to service points | Sharp edges, hot surfaces, rubbing zones and seam location. |
| OEM or distributor program | Repeatable finished dimensions and appearance | Approved material, hole schedule, panel identification and packaging. |
Specify only the barrier you need
For hanging dividers, compare the broader industrial curtain options. A curtain may use a top suspension system rather than fastening all four edges.
For outside panels, describe the frame and site exposure. A transparent sheet can catch substantial wind; a thicker sheet or closer hole spacing is not a substitute for a suitable support and attachment design.
For a greenhouse, visual clarity is not the same as measured light transmission or a horticultural optical specification. State the required measurement if the application depends on it.
Approve the assembly before a repeat order
For a new design, approve a representative material sample and a fabricated edge or pilot panel. Use the same drawing revision for production and inspection. This gives both parties a clear reference when appearance, hole alignment or packaging becomes important.
- STEP 01
Approve the material
Record the selected grade, thickness basis and tolerance. Compare clarity, tint, surface marks and handling with a retained sample.
- STEP 02
Check the finished geometry
Measure outside dimensions and the clear opening. Check hole centers from the stated datum, together with border width and corner details.
- STEP 03
Examine the finished interfaces
Inspect weld continuity, hem construction, grommet seating and sharp or loose hardware. Agree an assembly test method and acceptance criterion when pull-out performance is required.
- STEP 04
Confirm packing and records
Agree rolling or folding, protection between panels, item labels and drawing revision. Assess delivery creases against the agreed appearance standard.
If UV aging, low-temperature behavior or flame performance is required, request documentation tied to the proposed grade and relevant construction. A report for another material or thickness is not automatically evidence for the panel being ordered.
Plan for movement, water and maintenance
Install with a defined load path
Avoid pulling the panel into position by a single corner. Confirm how the perimeter and supports share the installation forces. Fastener choice and tension should follow the approved installation detail, with room for the intended movement and handling.
Review the need to remove or secure exposed panels during adverse weather with the installation designer. This page provides procurement information, not a wind-load rating.
Keep water outside the protected area
Grommet holes are intentional openings. Locate them appropriately, resolve overlaps and seam details, and prevent low points from collecting water. A waterproof sheet alone does not make a sealed enclosure.
Protect clarity during use
Use a cleaning method compatible with the selected grade. Start with a soft cloth, water and a mild cleaner approved for the material; try an inconspicuous area first. Avoid abrasive tools and unapproved solvents that can damage the viewing surface.
Inspect and store the panel
Check holes, corners, seams and rubbing points for elongation, cracks or separation. Clean and dry the panel before packing. Where appearance matters, compare rolled storage with folded storage during sample approval and avoid forcing stiff material around tight bends.
Send an opening photo, a sketch and the quantity
You do not need a complete engineering drawing to begin. A labeled photo and a simple sketch help establish the panel shape and fastening interface. For a firm production order, the agreed drawing and material specification should resolve the remaining details.
Include these details
- Application, installation location and indoor/outdoor exposure.
- Opening dimensions and required finished outside dimensions, with units.
- Clear viewing area, border width/color and preferred thickness or sample.
- Hole-center positions, usable hole diameter and mating hardware.
- Seam restrictions, access openings and any special performance evidence.
- Panel quantity, repeat-order needs, packaging and delivery destination.
What changes the quotation?
Material grade, sheet utilization, seams, reinforced edges, hardware count and packing all affect cost. A panel with many closely located holes may require more finishing work than an equal-area plain sheet.
Compare quotations using the same supply scope and dimensional basis. Ask DERFLEX to state the offered specification, included accessories, order quantity, production schedule and delivery terms for your project. No universal price, MOQ or lead time applies to every custom panel.
For a replacement order, send the approved previous drawing and describe what should change. Measuring only a stretched or damaged old panel can reproduce a poor fit.
Clear tarp and grommet questions
What is the best grommet spacing for a clear tarp?
There is no universal spacing. Match the hole positions to the support frame, reinforced border, panel dimensions and exposure. For an existing frame, provide hole-center coordinates from a labeled corner. Adding more grommets does not establish a wind rating or correct a weak border.
Is a clear tarp with grommets waterproof?
The clear PVC sheet forms a water barrier, but the finished assembly can admit water through grommet openings, sewn areas, seams or unsealed edges. Specify the seam construction, overlaps and drainage path. Keep fastener holes outside the area that must stay dry.
Should I choose 20 mil or 30 mil clear vinyl?
20 mil equals 0.508 mm and 30 mil equals 0.762 mm. These are thickness conversions, not DERFLEX stock specifications. A thicker sheet adds material and weight, while handling, cold flexibility, clarity, reinforcement and unsupported span still need review for the intended panel.
Can DERFLEX supply custom sizes and hole layouts?
DERFLEX offers clear PVC materials and custom tarp finishing. Submit finished outside dimensions, border details, the viewing side and a dimensioned hole layout for a project quotation. The quotation and approved drawing should identify the supplied panel, accessories and acceptance criteria.
Can clear tarp panels remain outside all year?
Year-round suitability depends on the selected outdoor formulation, temperature range, UV exposure, panel support and maintenance. Ask for evidence applicable to the proposed grade. UV treatment alone does not prove a fixed service life or a guarantee against yellowing.
Can I add grommets directly to clear PVC film?
Punching unsupported film can create local tear points. Establish a compatible reinforced edge, hole size, edge distance and fitting method before production. For a repair, assess the surrounding damage and test the proposed repair on a spare piece before returning the panel to service.
