Custom Tarpaulin Manufacturing
DERFLEX develops made to measure tarpaulin and custom PVC covers for buyers who need a defined finished size, practical reinforcement, controlled fastening points and material performance matched to the working environment.
Send a drawing, dimensions, photos or a sample layout. The material weight, panel plan, hems, eyelets, webbing, D-rings, welded seams, color, print and packing can then be reviewed as one specification rather than as separate add-ons.
A stock tarp is normally selected by nominal length and width. A made to measure tarp starts with the object, frame, cargo or area that must be protected and then works backward into the finished cover dimensions.
For a simple flat sheet, that may mean finished length, finished width and eyelet spacing. For a fitted machinery cover, trailer cover or box cover, the specification may also need height, drop, access openings, tension allowance, corner construction, panel orientation and the location of fixing points.
This distinction matters because dimensional accuracy alone does not guarantee a usable cover. If a tarp is measured tightly with no allowance for seams, tension, movement or installation, the finished product can be difficult to fit even when the numbers are technically correct.
Current ranking pages for this search commonly focus on exact size, PVC or canvas options, reinforced hems and eyelet spacing. For professional sourcing, the more useful question is how those elements interact during installation and repeated use.
State whether your dimensions refer to the final finished tarp or the fabric before hems and seams. For procurement, finished dimensions are usually the safer reference because they describe what must fit the application.
A flat tarp needs length and width. A fitted cover may require top dimensions, side drops, height, openings, flaps and corner treatment. A simple sketch can prevent major interpretation errors.
Eyelet spacing should follow the actual tie-down arrangement, wind exposure and load path. Even spacing is convenient, but engineered locations may be more practical for trailers, frames and equipment.
Very large tarpaulins are normally built from multiple fabric widths. Panel direction and welded seam location should be planned so seams do not interfere with high-stress corners, access points or drainage.
A cover that is pulled tight in service may need different allowances from a loose storage cover. Trucks, machinery and outdoor frames also introduce movement, vibration and repeated handling.
Fabric weight, coating, temperature, reinforcement and fabrication method influence flexibility and handling. The measurement plan should therefore be reviewed together with the chosen material grade.
For one-off projects, a drawing helps the factory interpret the cover. For distributors, fleets and OEM programs, the same drawing becomes part of a repeat-order control system.
Truck, equipment, storage, construction, agriculture, marine, shelter or resale program.
Finished size, drops, openings, shape, tolerance requirement and reference drawing.
PVC coated polyester weight, thickness, color, finish and performance options.
Welds, hems, eyelets, webbing, D-rings, straps, rope, pockets, flaps and branding.
Confirm critical dimensions and details before repeat bulk production where applicable.
The ranges below are typical DERFLEX custom directions and should be confirmed against the selected fabric, order quantity, seam layout, testing requirement and final application.
| Specification Item | Typical Options | Buyer Notes |
|---|---|---|
| Product Type | Flat sheet tarpaulin, fitted equipment cover, box cover, truck/trailer cover, curtain panel, outdoor storage cover, drawing-based cover | Send photos or a sketch when the cover is not a simple rectangle. |
| Material | PVC coated polyester, vinyl coated fabric, mesh, clear PVC or application-matched coated textile | PVC coated polyester is commonly selected for waterproof, weldable and heavy-duty custom tarpaulin work. |
| Common Weight Direction | Approx. 300–1200 gsm depending on material and project | Do not select GSM alone; consider base fabric, coating, tensile/tear requirements, handling and service environment. |
| Roll Width Direction | Approx. 1.02–5.10 m depending on structure and production route | Large finished covers may require a multi-panel welded construction. |
| Size & Shape | Square, rectangle, round, triangular, box/fitted cover, irregular drawing-based form | Very large or complex dimensions should be confirmed with a seam and handling plan. |
| Edge Reinforcement | Single/double hem, webbing reinforcement, rope-in-hem, corner patches, multilayer stress-zone reinforcement | Edge design should match wind, tie-down load and handling frequency. |
| Fixing Hardware | Brass, stainless or aluminum eyelets; D-rings; straps; buckles; elastic or rope interfaces | Specify location or spacing rather than assuming a default. |
| Fabrication | Hot-air welding, high-frequency welding, stitching or combined fabrication depending on design | Water-tight requirements should include the seam method in the specification. |
| Surface & Performance | Glossy/matte, lacquered, UV-resistant, FR direction, anti-mildew, cold-resistant, abrasion-resistant, printable options | Testing standards and target market requirements should be stated before production. |
| Branding & Packaging | Custom color, logo, technical marks, label, private label carton, roll label, export packing | Useful for distributors and repeat OEM programs. |
Specification note: performance and dimensional tolerances should be agreed in the order specification or approved sample. Available options vary by material, construction and quantity.
A clear measurement method helps reduce rework. These examples are planning references; the final production drawing should reflect your actual fit, hem, seam and tension requirements.
Finished tarp = required cover length × required cover widthAdd only the overlap or drop you actually need. Do not automatically add extra size if the requirement is already stated as finished dimensions.
Top length × top width + four side drops + corner constructionProvide top dimensions and each drop separately. If the object is tapered, curved or has handles, send a sketch or photos.
Reference datums + maximum envelope + openings + fixing pointsUse stable measurement datums rather than following every surface curve. Mark access doors, exhausts, protrusions and lifting points.
The strongest use case for custom sizing is not novelty. It is fit, fastening and protection around real dimensions that repeat from site to site, vehicle to vehicle or product to product.
Custom lengths, drops, flaps, D-ring rows, grommet spacing and reinforced zones for flatbeds, trailers, machinery transport and fleet applications.
Fitted or semi-fitted covers for machinery, generators, production equipment, outdoor assets, pallets and warehouse storage.
Roof covers, scaffold sheeting, material covers, containment panels and site-specific protective sheets where standard tarps create gaps or excessive loose material.
Hay, feed, grain, machinery and seasonal storage covers with custom dimensions, tie-down layouts and UV-resistant material options.
Made-to-order covers for stockpiles, crates, frames, furniture, temporary storage and irregular industrial assets exposed to weather and dust.
Repeat size programs, color coding, logo printing, labeling, packaging and specification records for regional distributors and tarp brands.
For a one-off cover, price and size may dominate the decision. For industrial or repeat procurement, the more important questions are specification control, fabric capability and fabrication consistency.
Can the supplier distinguish finished size from cut size? Can it explain how large panels are joined? Can reinforcement be placed only where the load needs it? Can eyelet locations follow a drawing instead of a fixed default spacing?
For repeat orders, also ask how custom colors, hardware, labels, packing and dimensional records are controlled between batches.
DERFLEX supports both PVC coated tarpaulin material selection and finished custom tarp fabrication. This helps procurement teams connect the fabric structure with the final cover design instead of treating the material and finishing as unrelated purchases.
Programs can include custom dimensions, coating/weight direction, reinforcement, hardware layout, welding, branding and export packaging, subject to order confirmation.
These related product pages cover the material, duty level and application topics that most often affect a made-to-measure tarp decision.
Answers below focus on the questions that influence fit, fabrication and purchasing decisions rather than simply repeating product features.
For a made to measure tarpaulin quotation, send DERFLEX your finished dimensions or drawing, application, quantity, material preference, fixing layout and reinforcement requirements. The team can review a practical material and fabrication direction for your project.
Commercial note: product availability, performance options, tolerances, compliance documents, sampling and lead time are confirmed according to the final specification and order conditions. This page avoids absolute performance claims that should instead be validated by material grade and project testing.
