APPLICATIONS:
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.
- Self-cleaning surfaceOptionalAvailable as an optional configuration. The surface finish helps dirt release from the coated face, supporting the appearance and routine care of exposed fabric panels.
What the Base Description Tells You
A 1300D yarn designation and a 30 × 32 construction describe different features of the polyester reinforcement in DLT-5903. The first concerns the yarn; the second concerns its arrangement in the base fabric. Neither is a description of a finished bladder joint. Keep the base specification alongside the total weight and thickness, then confirm the surface layers on the material selected for conversion.
Completing the Material Specification
The present record leaves the surface polymer and manufacturing route undefined. A useful DLT-5903 sample review should therefore identify those features before establishing joining settings. Bring a panel drawing and valve detail to the review so that the material can be considered in its proposed assembly. This connects the listed polyester base to the actual construction without assuming a coating, welding process or completed tank rating.
Application requirements — Flexible Water Tanks
Specify vessel or liner dimensions, liquid type, fill depth, support arrangement and the cleaning method. Review liquid compatibility, coating adhesion, seam integrity and the response to flexing and temperature. Distinguish a supported liner from a self-supporting finished vessel. Drinking-water, food-contact or other regulated uses need evidence for the exact proposed formulation and assembly.
Finished Pillow-Tank Configurations
Capacity, plan size and filled height must be specified together. The examples below describe complete welded tanks, not a capacity rating for the fabric.
| Specification | Configuration |
|---|---|
| 30 m³ Configuration Example | 8.20 × 4.44 m plan dimensions; 1.30 m stated height |
| 60 m³ Configuration Example | 10.00 × 5.92 m plan dimensions; 1.50 m stated height |
| 100 m³ Configuration Example | 12.10 × 7.40 m plan dimensions; 1.60 m stated height |
| Body Construction | Closed flexible shell assembled with high-frequency welded seams |
| Fittings | Valve, overflow and inspection hatch selected for the tank layout |
| Supporting Platform | Flat, clean and stable, with adequate bearing capacity and drainage |
| Service Clearance | Allow access around the tank for fittings and inspection |
| Stored Liquid | Confirm formulation compatibility and any required contact approval for the intended liquid |

Reading the Reinforced Base in Rainwater Bladder Material
DLT-5903 is listed for water tank material with a 1300D woven base and a 30 × 32 construction. The material entry identifies polyester, while the table gives a complete material weight of 2000gsm and thickness of 1.5mm. The yarn size and weave count describe the reinforcement. They do not establish the composition of every surface layer, and the current record does not identify a coating or lamination route for this model.
In a flexible rainwater bladder, the reinforced base is part of a larger envelope construction. Its yarns provide a framework through the sheet in two directions. The exposed surfaces, layer bonds and conversion process also influence whether the material can form the intended container. Those details should be confirmed on the supplied material sample, rather than inferred from the general application category. The listed width range is 1–3.2m, which can be considered alongside the panel cutting plan.
The 2000gsm and 1.5mm entries are useful starting measurements, but neither determines a finished bladder capacity. Panel shape, joins, support and fitting reinforcement belong to the finished design. For rainwater storage bladders, identify how water enters and leaves, where the container rests and which surfaces will contact it. Review the proposed seam and valve arrangement with the material configuration. Before production, include the surface composition and joining method in the agreed specification so that the converter is working from a defined composite rather than a polyester yarn description alone.
