  • UV resistance
  • High strength
  • Low elongation – no stretch
  • Weather durability
  • Wide range of accessories and "must haves" for antenna work

Designed for guying

The Mastrant® optimized ropes are made from proven modern materials: Polyester and Dyneema®. The range covers products for a variety of applications, from thin support lines used for tying wire antennas and beams, to guys for supporting small and portable masts and vertical antennas, to guying ropes for high antenna towers tens of metres high.

The development, testing and quality control of all these products ensures a superior product delivering long life. They are subject to continuous verifying in real conditions in co-operation with many users.
In the real life we have installations more than 10 years old with no signs of deteriorating.

“Is Mastrant® made from Kevlar?”

People are used to using Kevlar for “high strength ropes with lower elongation". No matter what material the rope is made of. Kevlar (or Technora, Twaron, etc.) are brand names for aramid fibres. Those fibres are susceptible to UV degradation so they are always protected with extruded outer protective jackets - for example Phillystran® HPTG-I.

However, there is another material for ropes for mast guying - high-modulus polyethylene; trade names are Dyneema® or Spectra®. It has excellent UV resistance, high knot strength and low specific gravity. Mastrant-M ropes using new Dyneema® Max Technology maximizes the scope of the world’s strongest fiber. Mastrant® is pioneering the use of high performance synthetic rope in permanently loaded applications. Designed specifically for mooring production facilities in deep waters, DSM’s new ‘ultra high strength at low weight’ Dyneema® DM20 fiber delivers unrivalled rope strength, stiffness, durability and longevity.

UV resistance

All Mastrant® ropes have covers made from Polyester, which is fully UV radiation resistant. The ropes made from pure Dyneema® have special protective finish which endows the rope with unusual UV radiation resistance.

High strength

The Mastrant® ropes are exceptionally strong – not only the extra-strong product line Mastrant-M, but also the basic Performance/Price optimized ropes overcome standard synthetic ropes.

Low elongation – no stretch

The design of Mastrant® ropes is optimised for guying – so the lowest stretch is one of the most important features what we had in the mind.

Weather durability

Mastrant® ropes are all weather durable and resistant to acids and alkali.

Wide range of accessories and "must haves" for antenna work

The assortment covers over 300 products for termination of the ropes, connecting, tightening, safe bending, cutting, ... When you are working on a mast, you can quite often move to different heights or positions. That is why it is necessary to be very careful and to use appropriate personal protective equipment – this is the reason why we also offer wide range of personal protective equipment and tools.

News

  • Camouflage ropes 2. 8. 2018

    We started production of "Camouflage look" of two sizes of Mastrant-P – called Mastrant-C. It is targeted for customers who need "invisible" guying in specific environment. The main color is tan with brown “dots”. They are available in sizes "3+" (3.5 mm, 9/64") and "6" (6.2 mm, 1/4"). 

     
  • New size of "P" rope: 3.5mm (9/64") 30. 7. 2018

    We started production of new size of rope Mastrant-P which fills the gap between "size 3" (diameter 2.6 mm) and "size 4" (diameter 4.4 mm). It is "size 3+" and has diameter 3.5 mm (9/64"). Breaking strength is 300 daN (about 300 kg or 660 lb.).  
  • Strength of P4 and P5 26. 4. 2018

    We are updating the ratings for Breaking Strength and Safe Working Load for our most popular rope, 4mm and 5mm Mastrant-P. We began improving the construction of this rope in our production process more than 6 years ago and have been testing samples from each run. We are now satisfied that the changes have resulted in consistent, permanent improvements. Here are the new ratings:
    Mastrant-P, 4 mm: BS=440 daN (about 440 kg, 970 lb.), SWL=132 daN (about 132 kg, 290 lb.)
    Mastrant-P, 5 mm: BS=540 daN (about 540 kg, 1190 lb.), SWL=162 daN (about 162 kg, 360 lb.)
