01
More than a tarp sheet
A side curtain tarp is the flexible side panel of a curtain-side truck or trailer. It slides or folds away for loading, then closes to help protect cargo from rain, road spray, dust and routine transport exposure.
Because it functions as part of a moving vehicle body system, the material must be selected for tension, wind, repeated handling, rail movement, welded seams, strap zones, cleaning and surface appearance—not only for nominal fabric weight.
Fit, appearance and service continuity
Replacement curtain projects may require measured dimensions, compatible hardware zones, color matching, reinforced edges and practical lead-time planning.
Cargo protection with operational access
Side access can support frequent loading routes while the closed curtain provides a flexible weather barrier and a consistent fleet appearance.
Roll supply and customization support
Choose a specification that can be cut, welded, reinforced, printed and reordered with clear production and packaging requirements.
System thinking
How the curtain material fits the trailer
A productive sourcing discussion begins with the complete curtain system rather than a generic roll description.
1
Upper movement zone
The fabric works with rollers, tracks or sliding hardware and must remain flexible during routine opening and closing.
2
Main sidewall panel
The broad surface manages wind, weather and visual presentation, including printed graphics where required.
3
Reinforced stress areas
Welded patches, hems, pockets, buckles, strap points and lower edge zones need compatible processing performance.
4
Lower tensioning system
Buckles, straps, hooks and related hardware keep the closed curtain positioned along the trailer body.
Specification framework
Typical side curtain tarp options
The right construction depends on curtain size, trailer design, operating climate, print process, expected handling and local compliance needs.
| Selection item | Typical direction | Why it matters to the buyer |
|---|---|---|
| Material structure | High-tenacity polyester base fabric with PVC coating on both sides | The polyester carries mechanical load; the PVC layer provides weather protection, surface finish and welding compatibility. |
| Weight range | Approximately 650, 750, 850 or 900 g/m²; custom structures may be discussed | Lighter grades can improve handling, while heavier grades may suit larger panels or tougher fleet conditions. |
| Width direction | Common project range around 1.02–3.20 m, subject to construction and order plan | Correct width can reduce welding lines, cutting waste and production complexity for the curtain converter. |
| Surface finish | Glossy, matte, embossed, lacquered or print-oriented finish | Surface choice affects appearance, cleanability, graphics and compatibility with the intended printing method. |
| Color | Common fleet colors or project-matched colors | Color should be confirmed by physical sample or agreed reference, especially for repeat fleet branding. |
| Performance options | UV, anti-mildew, low-temperature flexibility, anti-wicking or flame-retardant direction | Optional treatments should be selected against the destination climate, use environment and required test method. |
| Fabrication route | Hot-air welding, high-frequency welding, cutting, hems, reinforcement and strap-area processing | Sample testing helps verify weld settings and finished-panel behavior before volume production. |
| Supply format | Roll goods, cut panels or project-based converted curtain components | The format should match local fabrication capacity, shipping efficiency and installation responsibility. |
The values above are commercial reference directions, not a universal guarantee. Final construction, tolerances, test methods, treatment combinations and supply format should be recorded in the approved technical sheet and purchase agreement.
Selection guide
Choose by operating need—not by gsm alone
Material weight is one part of the decision. Base cloth, coating uniformity, flexibility, weldability, finish and repeat-order consistency also influence the finished curtain.
Balanced fleet curtains
A 650–750 gsm direction is often considered when handling weight, flexibility and commercial cost need to stay balanced.
- Standard curtain-side trailer programs
- Regional delivery and routine freight
- Printed logistics curtains
- Projects that prioritize easier handling
Heavier-duty curtain programs
An 850–900 gsm direction may be appropriate for larger side panels, frequent operation or projects that prioritize a more robust structure.
- High-use fleet replacement programs
- Long trailer side panels
- More demanding route conditions
- OEM programs with stronger material targets
Print-focused fleet branding
Printed curtains require surface selection, ink compatibility and color approval in addition to mechanical performance.
- Smooth print-oriented top surface
- Solvent, eco-solvent, UV or latex direction
- Logo layout and panel seam planning
- Sample print and adhesion review
Practical comparison
Where side curtain tarps are a practical fit
Side curtains combine flexible access with cargo shielding, but each vehicle body concept has different priorities.
Side curtain tarp system
- Fast access along a large part of the trailer side
- Useful for forklift loading and multi-stop logistics
- Supports printed fleet identity
- Requires correct tensioning, reinforcement and maintenance
Rigid box body
- Fixed enclosure and hard side panels
- Often accessed through rear or selected side doors
- Different repair and body-building process
- Less flexible for full-length side loading
General flat tarp sheet
- Useful for removable covering and tie-down protection
- Not automatically designed for sliding curtain hardware
- May lack dedicated strap, pocket and reinforcement layout
- Material suitability must be checked before conversion

FAQ
Side curtain tarp purchasing questions
Clear answers for trailer builders, fleet operators, distributors, repair companies and tarp converters.
What are side curtain tarps usually made from?
They are commonly made from PVC-coated polyester fabric. The woven polyester provides structural reinforcement, while the PVC coating provides a weather-resistant surface, weldability and finish options for transport use.
What gsm is suitable for a truck or trailer side curtain?
A common commercial range is approximately 650–900 g/m². A 650–750 gsm direction may suit balanced fleet applications, while 850–900 gsm may be considered for larger panels or more demanding service. The final choice should also consider base cloth, coating, curtain size and operating conditions.
Can DERFLEX supply replacement side curtain tarps?
DERFLEX can discuss replacement-curtain projects based on dimensions, color, material structure, reinforcement layout, printing and supply format. Accurate measurements and photos of the existing system are useful during evaluation.
Can the curtain material be printed with fleet graphics?
Yes, print-oriented surface options can be discussed. The printing method, ink system, surface finish, color target and artwork layout should be confirmed during sampling because these factors affect the final result.
Is the fabric suitable for hot-air or high-frequency welding?
PVC-coated curtain fabric is commonly converted by hot-air or high-frequency welding. A production trial with the selected specification and the converter's equipment is recommended before mass processing.
What information is needed for an accurate quotation?
Please provide trailer or truck type, required curtain dimensions, target gsm, roll width or panel format, color, finish, printing requirement, optional treatments, order quantity, destination and any required test or documentation standard.
