Quality
Numbers on the line, not adjectives on the brochure
Every lot is measured at three points: the start, the middle and the end of the run. Thickness, shade factor, mesh aperture or flow rate is recorded, photographed and filed against the lot number.
Products are internationally certified, and the documentation pack travels with the shipment. Test reports and third-party inspection can be arranged on request.
Control points
Five checks between resin and container
- 01
Incoming resin
Virgin resin grade, density and carbon black content checked against the lot certificate before the hopper is loaded.
- 02
In-line gauging
Thickness is measured continuously during extrusion; out-of-tolerance material is diverted rather than wound.
- 03
Lot sampling
Three samples per lot: thickness or shade, tensile strength and elongation, and a visual check for gels, holes and edge trim.
- 04
Finishing check
Width, roll length, core size, stitching or grommet pitch and printing are checked against the order confirmation.
- 05
Pre-loading inspection
Pallets are photographed, counted and sealed, and the packing list is reconciled with the loading plan before the doors close.
Test regime
What gets measured, and how
A measurement without a method is a marketing sentence. These are the properties we record per lot, and the instrument used.
| Property | Product | Method / instrument |
|---|---|---|
| Thickness | Mulch film, greenhouse film, geomembrane | Digital micrometer, 10 points across the width |
| Tensile strength & elongation | Film, fabric, geomembrane | Tensile tester, machine and transverse direction |
| Shade factor | Shade net | Light transmission measurement per lot, ±3% nominal |
| Mesh aperture | Insect net | Optical measurement, aperture stated in microns |
| Flow rate & variation | Drip tape | Gravimetric flow test across the run, ±5% standard |
| Weight & light block | Weed control fabric | GSM check and light transmission, ≥90% block |
| Cell geometry | Seedling trays | Cavity depth, pitch and drain size against the drawing |
| Carbon black content | Geomembrane | Lab analysis, 2.0–3.0% target |
Documents
What arrives with the container
- Packing list — rolls, coils and pallets by grade and lot number.
- Lot inspection record — the measurements taken on the line, with the sample photographs.
- Loading plan — issued before shipment and reconciled at handover.
- Welding parameters — for geomembrane orders, wedge and extrusion settings.
- Installation notes — anchor trench, seam overlap and panel sequence where relevant.
