Application and Load
Truck cargo, machinery, roof protection, farm storage and warehouse curtains place different stress on the tarp. DERFLEX starts from wind load, abrasion, folding, UV exposure, temperature and tie-down method.
Custom Tarp Specifications: Size, Weight, Color, Grommets and Printing
A custom tarp should not be ordered by length and width only. For truck covers, equipment protection, construction sites, agriculture storage, outdoor shelters and OEM tarp programs, the real performance comes from a complete specification: material structure, finished size, GSM, color system, edge reinforcement, grommet spacing, welding, logo printing and packing.
DERFLEX helps distributors, tarp fabricators, fleet operators, contractors and industrial buyers build heavy duty PVC tarpaulin programs around real working conditions instead of simple retail stock sizes.

What Should Be Included in a Custom Tarp Specification?
Many custom tarp pages let users enter a size, choose a fabric and add grommets. For industrial procurement, that is only the beginning. A professional specification should define how the tarp will be used, how it will be pulled, where it may fail, how it will look, and how repeat orders will stay consistent.
Material and Fabrication
The base fabric, coating weight, surface finish, welded seams, reinforced hems, webbing and corner patches should work together. A heavier sheet without the right edge design can still fail early.
Brand and Supply Model
For importers and OEM brands, specifications should include color matching, logo placement, label design, carton packing, roll size, pallet loading and documentation for repeat supply.

Custom Tarp Specification Table for Industrial Buyers
Use this table when preparing a quotation request. Final values should be confirmed according to end-use, market requirements, MOQ, test method and production feasibility.
| Specification Item | Common DERFLEX Options | How Buyers Should Decide |
|---|---|---|
| Finished size | Custom length and width; rectangular, square or project-based shapes; roll goods, cut sheets or finished tarps. | Measure the object or coverage area, then add practical allowance for overlap, shrinkage, tie-down tension, hem folding and installation method. |
| Material weight | Approx. 450–1500 gsm PVC coated polyester tarpaulin direction for medium, heavy and severe-duty applications. | Choose lower weights for easier handling and higher weights for repeated pulling, truck covers, machinery covers, exposed storage and long outdoor service. |
| Base fabric | High-tenacity polyester scrim such as 500D, 840D, 1000D or customized yarn density based on strength direction. | Higher denier and denser scrim improve tensile and tear resistance, but flexibility and folding requirements should also be considered. |
| Color | Black, white, blue, green, gray, red, orange and custom color programs for larger orders. | Color affects heat absorption, brand identity, visibility, dirt appearance and outdoor aging perception. Confirm color tolerance before bulk orders. |
| Surface finish | Glossy, matte, embossed, lacquered, anti-mildew, easy-clean or printable surface directions. | Glossy surfaces look bright and clean; matte or embossed surfaces can reduce glare and improve industrial appearance. Printing requires surface compatibility. |
| Edges and hems | Heat-welded hems, sewn hems, double-folded edges, rope hem, webbing reinforcement and corner patches. | Most failures begin at edges, corners and tie-down points. Reinforcement should match wind, tension, handling frequency and installation method. |
| Grommets / eyelets | Brass, stainless steel or plated metal options; custom diameter; spacing by application; reinforced corner and side placement. | Closer spacing is useful for higher wind and tighter tie-downs. Wider spacing may be enough for light covers. Hardware should be matched with rope or bungee size. |
| Printing and branding | Logo printing, warning text, serial markings, private label, carton label and OEM packaging support. | Provide vector artwork, Pantone or color reference, print area, viewing distance, expected durability and packing requirements. |
| Performance options | Waterproof, UV-resistant, flame-retardant direction, cold-flexible direction, anti-mildew, abrasion resistance and oil-resistant direction. | Confirm special requirements before sampling because they must be designed into the formulation rather than added after finished tarp production. |
| Supply model | PVC tarp rolls, semi-finished panels, welded sheets, finished tarps, bundled sets and OEM packed goods. | Converters often prefer rolls; distributors and fleets may need finished tarps with labels; projects may need large welded panels ready for installation. |
Commercial guidance only. DERFLEX can confirm technical values, tolerances and material options after reviewing the actual application and order plan.
Size planning
How to Specify Custom Tarp Size Without Ordering Too Small
Accurate sizing is more than measuring the top surface. Industrial tarps usually need allowance for side drop, overlap, hem folding, shrinkage direction, hardware position and the way workers will pull the cover into place.
✓Measure the full coverage area, not only the visible top surface.
✓Add drop length for equipment sides, pallet stacks, cargo height or frame edges.
✓Confirm whether size means cut size, finished size or usable coverage size.
✓Mark seam direction if the tarp is wider than available roll width.
Size Details That Reduce Field Problems
Finished size: the final dimension after hemming and welding. This is the most useful value for end users.
Cut size: the material dimension before folding and edge finishing. It is mainly used by fabricators.
Coverage size: the practical area the tarp can protect after installation, overlap and tie-down tension are considered.
For repeat OEM programs, DERFLEX recommends recording a size drawing with width, length, edge structure, grommet position, corner patch size, printing location and packing fold direction.
Weight and durability
Choosing Tarp Weight: GSM, Thickness and Real Strength
Buyers often ask for “thicker tarp”, but tarp durability depends on a system: yarn strength, coating adhesion, total weight, surface treatment, seam welding, corner reinforcement and how the cover is installed.
450–610 gsm Direction
Suitable for medium covers, warehouse partitions, temporary outdoor protection and applications where easier handling is important.
- Lower unit weight
- Flexible folding
- Cost-sensitive programs
650–900 gsm Direction
Commonly selected for truck covers, construction tarps, farm storage, equipment protection and repeated industrial use.
- Better tear resistance
- Improved outdoor durability
- Good OEM tarp range
900 gsm+ Direction
Used when the tarp faces rough handling, stronger tension, exposed outdoor storage, large panels or demanding machinery protection.
- Higher abrasion resistance
- Stronger edge system needed
- Best for severe-duty direction
Color and branding
Custom Tarp Colors for Visibility, Heat Control and Brand Identity
Color is not only an appearance choice. It can influence heat build-up, dirt visibility, safety marking, brand recognition and market positioning.
Black
Blue
Green
Red
Orange
Gray
White
Custom
Dark Colors
Black, dark blue and green are often selected for cargo covers, construction covers and outdoor equipment because they hide dirt and create a strong industrial appearance.
Light Colors
White, light gray or reflective directions may be preferred where heat control, visibility or clean appearance is important. Confirm stain resistance and surface finish.
Brand Colors
For fleets, retailers and OEM brands, color matching should be managed with samples, tolerance agreement and repeat-batch control to keep products consistent.
Grommets and reinforcement
Grommet Spacing Should Match Wind, Tension and Installation Method
Grommets make the tarp easier to fasten, but they also concentrate stress. A good tarp specification defines the grommet material, diameter, spacing, edge reinforcement and corner patch structure together.
For exposed outdoor use, corners normally need extra reinforcement because workers often apply the strongest tension there. For truck covers and equipment covers, side spacing should match the tie-down system, bungee cord, rope diameter or frame connection method.
Common Hardware and Edge Options
✓Brass, stainless steel or plated metal eyelets based on corrosion and budget requirements.
✓Custom grommet spacing for light covers, moderate wind or frequent tie-down use.
✓Double hems, webbing reinforcement, rope hem and welded corner patches.
✓D-rings, straps, buckles, hook-and-loop strips and labels for finished tarp programs.
✓Edge drawings available for repeat OEM and distributor products.
Logo printing and OEM
Custom Printed Tarps for Fleets, Distributors and Brand Programs
Printed tarps can turn a protective cover into a visible brand asset. DERFLEX can discuss logo printing, safety text, product labels and private-label packaging according to surface finish, order quantity and expected outdoor exposure.
Logo and Text Printing
Provide vector artwork, color references, logo size, print position and expected viewing distance. Printing should be matched with surface finish and material color.
Private Label Supply
Distributors can request branded labels, carton labels, folded packing, barcode direction and repeat specification files for long-term product lines.
Fleet and Project Marking
Fleet names, safety warnings, part numbers and serial markings can help identify tarp sets, reduce confusion and improve management in the field.
Application matching
