Product Features
- Flame retardantOptionalAvailable as an optional configuration. A flame-retardant formulation for fabricators supplying projects with defined fire-behaviour requirements. Select the grade around the test method required for the finished application.
- BlockoutOptionalAvailable as an optional configuration. Restricts light passing through the fabric for roof, curtain or cover panels that need an opaque finish and greater control of the light behind the surface.
Polyester Core and Coating Bond
The 1000D designation describes yarn size in both fabric directions. The separate 20×20 entry describes the base construction and should be kept with the yarn specification when comparing samples. DLT-5702 combines that reinforcement with PVC faces at a total mass of 650gsm. Its adhesion figure concerns the interface within this composite; it should be considered separately from tensile force and resistance to a growing tear.
Knife Coating and Roll Conversion
PVC paste is spread onto the base fabric and controlled with a coating blade, then heated to form the finished layer. Glossy or matte selection affects the surface presented to a printer or seam maker. An optional blockout layer changes the material configuration, so fabrication trials should use that selected version. Check the finished seam and its flexibility before approving a roof panel layout.
Application requirements — Truck Covers
Specify the finished cover dimensions, fixing arrangement, folding or rolling pattern and operating environment. Review tensile and tear properties, coating adhesion, abrasion at contact areas and the strength of seams and reinforced edges. State the required surface finish, flexibility and weathering conditions, and assess a sample in the proposed assembled construction.
Finished Flatbed-Tarp Configurations
The following dimensions describe a flatbed lumber tarp. Side curtains and roll-over roofs use their own body and hardware drawings.
| Specification | Configuration |
|---|---|
| Flat Size Example | 24 × 27 ft (approximately 7.32 × 8.23 m) |
| Side Drop Example | 8 ft (approximately 2.44 m) |
| End Flap Example | 8 × 8 ft (approximately 2.44 × 2.44 m) |
| Panel Seams | Heat-sealed body seams |
| Edge Construction | Double-stitched hems reinforced with 2 in (approximately 51 mm) webbing |
| Eyelet Spacing Example | 2 ft (approximately 610 mm) around the specified edges |
| Tie-Down Arrangement | Three D-ring rows with protective flaps in this configuration |
| Fit And Restraint | Set the cover around the actual load dimensions; cargo restraint is specified separately |
Construction Details
Reinforced Hem
The webbing runs within the hem to support the eyelets and stitched edge. Confirm corner and end-flap reinforcement on the finished drawing.
Protected D-Ring Attachment
D-rings are attached through reinforced areas, with flaps separating hooks from the tarp face. Choose ring positions to suit the load height and tie-down route.

PVC Knife Coated Tarpaulin: Reinforcement and Coating
DLT-5702 is a 650gsm PVC knife coated tarpaulin with a 1000×1000D polyester base fabric in the listed 20×20 construction. Polyester yarns form the reinforcement inside the sheet, while PVC covers both faces. The yarn network carries tension through the fabric; the flexible outer layers close the spaces between yarns and provide the surfaces used during fabrication.
Knife coating starts with PVC paste applied to the textile. A blade meters the wet coating before heating gels and fuses it into a continuous layer. This describes the production route, without specifying a plant temperature or coating recipe. The resulting bond between reinforcement and PVC is a separate property from the strength of the woven core.
The data sheet lists tensile strength of 2750/2500N/5cm and tear strength of 280/240N/5cm. Tensile testing pulls an intact strip, whereas tear testing follows the growth of a cut. The listed adhesion value is 100N/5cm. Reading these properties together gives a more useful picture of the composite than choosing by its mass alone.
Glossy and matte surfaces are listed, with an additional blockout layer available by specification. Roll widths run from 1.05m to 3.2m, with 50m or 100m lengths. For a proposed sliding trailer roof, review a sample for folding and seam construction alongside the roof hardware. The roll material specification does not determine the assembled roof’s operating performance.
