DuraTarps materials from Duletai
DuraTarps is a material brand of HAINING DULETAI NEW MATERIAL CO.,LTD, offering PVC-coated and laminated fabrics for fabricators and distributors. From truck covers and tents to ventilation ducts and other industrial applications, material selection starts with the finished product: how it will be made, where it will be used and what it needs to withstand.
Looking for a material that works with your production process? Bring us your requirements for weight, flexibility, surface finish and joining method. Our manufacturing equipment, laboratory testing and sample-making facilities support the review of material constructions and formulations. Product photographs, technical data and sample discussions help you compare options against your application before settling on a specification.
Whether you are developing a new product or reviewing an existing material, send us your application, target specifications and estimated quantity. A reference sample or details of the problem you want to solve can make the discussion more useful. We can review material and sample options with you, along with roll dimensions, packing and shipment requirements, so your enquiry moves towards a practical proposal.

Manufacturing & Quality
Select a tab to explore our production and testing.
Manufacturing Process
From Base Fabric To Shipment
Each order starts with the application and the agreed material construction. The production route connects reinforcement, PVC formulation and finishing with inspection, packing and dispatch.
- 01
Base Fabric
The polyester reinforcement is selected for the intended construction. Yarn and weave help define material strength and handling.
- 02
PVC Preparation
The PVC formulation is prepared for the specified colour, flexibility and surface requirements, alongside the selected production route.
- 03
Lamination Or Coating
PVC joins the reinforcement by lamination or coating. See our production equipment for details of each process.
- 04
Inspection & Testing
Inspection and laboratory checks review material against the agreed order specification. Follow our quality-control steps.
- 05
Rewinding & Packing
Finished material is rewound and packed for transport. Width, length and identification are checked against the order.
- 06
Warehouse & Loading
Goods are prepared for dispatch and container loading. Share your destination and shipment plan to discuss packing and delivery.
Manufacturing Equipment
Production Equipment & Colour Control
Tell us the application, target weight or thickness, width and fabrication method. We can help you compare a suitable construction and arrange samples for evaluation before you confirm the specification.
Calendering LineUp to 5 meters wide
Calendering forms PVC compound into a continuous film through heated rollers. Thickness and finish are selected for PVC films and laminated fabric materials.
Discuss film thickness and finish
Lamination LineUp to 5 meters wide
Lamination bonds PVC film to a textile reinforcement. Film layers and base fabric are selected for the weight, flexibility and fabrication your application requires.
Compare laminated fabric samples
Knife Coating LineUp to 5 meters wide
Knife coating applies PVC to the fabric reinforcement with a controlled gap before heat treatment. Base fabric, coating weight and finish are selected for your use.
Discuss a coated-fabric specification
Automatic Colour Dispensing System
Automatic dosing prepares coloured coating paste and helps keep batches consistent. Share a colour reference or physical swatch to discuss matching and sample options.

Perforating & Slitting Services
Prepare your material for the next stage of production. Share your drawing or processing requirements so we can discuss perforating and slitting for your order.
Perforating
Tell us the hole size, spacing and layout, including any edge-distance requirements. A drawing or sample helps us review the pattern with you.
Slitting
Specify the roll widths and lengths needed for your production process. We can discuss slitting the material into narrower rolls to suit your requirements.
Quality Control
From Incoming Materials To Retained Samples
Our quality team checks materials through production, supported by laboratory testing. Inspection results are reviewed against the agreed specification, with non-conforming results investigated before the issue is carried into the next batch.

Packing & Loading
Protection For Storage & Transport
Paper cores and virgin-plastic plugs protect fabric rolls. PE film, kraft paper and rigid sleeves provide outer wrapping. Cases, pallets and protective boards suit different shipment needs. Steel tubes support selected projection-screen materials, while steel racks organise factory stock. We confirm packing with you before dispatch.
Our Laboratory
Material Testing And Development
Reinforcement, coating adhesion and surface performance each affect the finished material. Our laboratory supports physical and chemical testing, formulation work and sample preparation. Welding, abrasion and ageing tests are included where required for the selected product.
Lightfastness Testing
Exposure testing checks light-related changes in the specified material.
Flammability Testing
The fire-test method and material configuration are agreed for each project.
Low-Temperature Torsion Testing
Low-temperature twisting checks material flexibility under conditions selected for its use.
Chemical Analysis
Chemical analysis supports material development within the agreed testing scope.
Low-Temperature Impact Testing
A conditioned specimen is hit at low temperatures to assess cold-weather brittleness.
16P Environmental Testing
Equipment for 16P testing of material samples against the selected test requirements.
Heavy Metal Testing
Equipment for heavy metal testing of material samples within the agreed test scope.
Sample-Making Machine
Equipment for preparing small material samples for product development and review.
