Why use MASTRANT?

Optimalization

Do you want to sleep soundly? Even if you have a high mast very near to your house and a storm is coming? Is the strength of your steel guy-wires sufficient and is their corrosion level still negligible? The safety of your antenna masts and verticals depends on the quality of your guying and therefore on the quality of the materials used for guy-ropes. Are you aware of that the standard steel guys are obsolete? They are heavy, conduct electricity, and are problematic from the viewpoint of handling and corrosion. Modern, non-metallic ropes are no longer a second choice, offering unique benefits not found in out-of-date steel cables.

Modern Materials

The basic properties of any rope depend on its material composition. The production of our non-metallic rope uses the most modern recently developed materials – Dyneema, Vectran, specially prepared polyester, polyamide and our own special high strength polypropylene fiber, MULTITEX. These materials are extremely reliable in terms of:

• Their unusual high strength.
• Negligible elongation and elasticity.
• Outstanding durability and resistance to environmental damages including UV radiation.
• A minimal bending radius enabling the possibility of knotting without the risk of damage.

Advances in Development and Testing

The utmost care and attention is taken during the development, testing and quality control of our ropes. The ropes are tested in laboratory conditions, where the basic parameters – strength, flexibility, elongation and degrees of abrasion due to wearing – are measured and evaluated. They are then tested in real-life conditions with the assistance of many professionals who are an integral part of the ropes development. The professionals test the ropes in practice by evaluating their behavior and other parameters difficult to assess through laboratory testing.

Wide Variety of Products

We chose our assortment very carefully; offering ropes for guying small masts or mobile constructions and vertical structures as well as solutions for big masts up to the height of dozens of meters. For these purposes special heavy duty ropes, MASTRANT, have been developed. We also offer D-F1 ropes which are the strongest and most durable non-metallic guys accessible on today’s market for the most stringent needs.

"Is Mastrant made from Kevlar?"

People are used to using Kevlar for "strong ropes with small elongation" - no matter what material the rope is made of. Kevlar (or Technora, Twaron, etc.) is a brand name for ropes from aramid fibres used in the past. Nowadays, the material has been replaced by LCP (trade name is Vectran) which has better properties. However, there is a better material for ropes for anchoring - high tenacity polyethylene; trade names are Dyneema or Spectra. It has excellent UV resistance, higher knot strength and much lower specific gravity in comparison with Vectran. This is Mastrant-D - double braided rope, core is braided 100% Dyneema SK 75, inner cover is Polyester staple (only on ropes with diameters from 6 mm and up) and outer cover is Polyester 12, 16, 24 or 40 (depending on the diameter). We used to offer ropes from Vectran in our assortment (it is Mastrant-V). Recently, we replaced it with the new rope Mastrant-P which is better for our purpose (guy-wire). This is braided rope with twisted cores (core: Polyester, parallel-arranged twisted cores, cover: Polyester 12 or 16). It has lower strength and higher elongation than Mastrant-D, but all other properties needed for guying are similar. Moreover it has much higher knot strength and Mastrant-P is dramatically cheaper. Thus Mastrant is not from Kevlar. Mastrant is optimized for anchoring.
