Support lines that don't rust or lose tension
Support lines are the tensioned load-bearing cables that carry crops and agricultural structures. AGROPET® is the high-tenacity polyester (PET) monofilament that replaces galvanised wire in these lines: it doesn't rust, is dielectric and weighs 5 times less than steel. For main and heavily loaded lines we work with the 3, 4 and 5 mm gauges.
Support lines
What a support line is and why AGROPET®
A support line is the load-bearing or carrying cable tensioned between posts to hold the weight of a trellised crop, a screen, a cover or the agricultural structure itself. It is the line that builds up the most load throughout the whole season, so it needs a stable breaking strength and a material that won't slacken or deteriorate out in the open. The AGROPET® polyester monofilament tensions at 1% with Gripple® or strainers, recovers elastically and holds its tension season after season, with no need for the constant re-tensioning that wire requires.
Compared with galvanised steel wire, AGROPET® brings three decisive advantages to a load-bearing line. It never rusts: it is 100% immune to damp, salt air and crop sprays, so it doesn't stain the crop or lose load over time. It is dielectric (doesn't conduct electricity), safe alongside power lines and fertigation. And it is about 5× lighter than steel (1,36 g/cm³), which speeds up the installation of long runs. It withstands UV and temperatures from −40 °C to +90 °C, is 100% recyclable and made in Europe by Textil Villa de Pego, S.L. (Pego, Alicante), certified to ISO 9001 and ISO 14001.
- It never rusts: PET polyester is 100% immune to damp, salt air and crop sprays, so the line doesn't stain the crop or lose load over the years.
- Dielectric: it doesn't conduct electricity, so the support line is safe alongside power lines and fertigation systems.
- 5 times lighter: at 1,36 g/cm³ against steel, long runs are handled and tensioned far faster, without cutting your hands.
- Holds its tension: it tensions at 1% with Gripple® or strainers and recovers elastically, without the season-after-season re-tensioning that wire demands.
- Strong and sustainable: it withstands UV and −40 °C to +90 °C, is 100% recyclable and made in Europe to ISO 9001 and ISO 14001.
