The below is for your reference from internet but we can produce same.

A highly technical high specification rope. Astraline yarns are produced with a polymer core and high grade polyester cover. This composite yarn has been proven to give excellent performance in resisting abrasion. Its low friction leads to a decreased heat development inside the rope giving a higher safety factor and a longer rope life. Wet breaking strength is 20% higher than nylon, it doesn’t absorb water and because of its low snap back, it is ideal for longstanding cyclic loadings. Astraline is an outstanding top of the range mooring rope and is OCIMF certified for offshore use.

Manufactured in 8 strand (4 x 2) platted construction.

Typical Applications: Ferry operations, tug companies, oil supply vessels, tankers, mooring installations and cruise liners.

Size: 40mm - 96mm

Gael ForceCoronaLine

A composite rope consisting of one or more torque balanced 8 strand platted ropes in the core, with a circular braided jacket. All of the fibres are produced in specially treated polyester yarns which reduce yarn to yarn abrasion. This combination leads to reduced heat build-up under repeated loading conditions. Corona Line has a breaking strength which is equal in wet and dry conditions.

Manufactured in multiple 8 strand (4 x 2) platted ropes with a braided jacket.

Typical Applications: Deep sea mooring lines.

Size: 48mm - 80mm

Nylon Multiplatt Mooring Rope

Manufactured in 8 strand (4 x 2) platted construction.

Typical Applications: Ferry operations, tug companies, oil supply vessels, tankers, mooring installations and cruise liners.

Size: 44mm - 80mm

Gael Force Orion Line

A high specification rope produced from a composition of Polyver fibre core yarns covered with high grade polyester. The polyester cover gives increased abrasion resistance and breaking strength while the Polyver core gives the rope a specific gravity of 0.98 allowing the rope to float. The high breaking strengths and good abrasion resistance make this rope ideal for moorings and is less expensive than many other high specification ropes.

Typical Applications: Mooring Lines, Towing Lines, Fish Farming, Messenger Lines, Pick-up Lines.

Size: 40mm - 64mm

Gael Force Seamaster Rope

Made from specially extruded polysteel fibres and manufactured to very tight tolerances, to a specification designed to resist the very high repetition of cyclic loads experienced in a fixed mooring installation. Seamaster gives very high break loads and is the optimum specification fish farm mooring rope. Every coil is tested and supplied with a test certificate.

Size: 32mm - 48mm

8STRANDPLAITED ROPES

The 8 strand constructions are plaited ropes made so in order to eliminate the tendency twisted ropes have to rotate under weight / load.

They are produced on machines containing 8 (eight) reels in groups of two "twills", revolving around each other in pairs to form the 8 strand plaited construction.

The 8 strand rope developed after the World War II is still used even today in a broad range of applications. Depending on the use and on the experience of the user a lot of man made material and even combinations of them are used in this construction.

The materials normally used and care taken during manufacturing is the same as the 3 – strand ropes and as far as WLL is concerned it is the same for the same diameter ropes.

8STRANDMIXED MATERIAL ROPES

Our company has been producing mixed fiber ropes for more than 35 years now.

In recent years OCIMF has issued guidelines regarding the performance of materials in relation to several applications. Our constructions of mixed materials meet in full the OCIMF guidelines through a process that was well known to us.

The fibers used, high density olefin and polyester the later placed mostly on the ropes su***ce in such a formation so that the best qualities of each material involved are taken to advantage.

The most common rope constructions are the ones mentioned below.

Float 8: 25% polyester and 75% high density olefin per weight costruction is used with the polyester covering 100% of the rope's su***ce, yet costructing a floating rope.

Flex 8: 40% polyester and 60% high density olefin fiber per weight construction is used. The ropes su***ce is totally covered by - thick polyester jacket ensuring increased abrasion and temperature resistance (Non floating).

Strong 8: 50% polyester and 50% high density olefin fibers per weight construction. This rope having all the qualities of the Flex construction is really made to prove its name.

Oceanic 8: The latest development of our industry in the mixed material 8 strand ropes with 30% of the su***ce fibers being polyester and 70% high density olefins. A combination that guarantees floatability and high braeking loads.

DOUBLE BRAIDED MULTISTRANDROPES

The particular field (double braided multi strand ropes) is a combination of one or two fibers constructed as two concentric elements, both braided.

The first one – called core – is a multi strand braided rope of itself.

Then, over it, a second multi strand braided rope – called jacketed – is woven.

The two ropes perform as a single intergraded extremely strong member and the outer layer shields the rope entirely from abrasion.

In this combination both elements, core and jacket, must be almost equal to each other on weight, about 50%. The aberration can only limit to a 45%-55% analogy in any case.

In this construction care has been taken so that no strand interchange will exist in core or jacket through its entire length.

The linear density corresponds to the net mass per length of the rope expressed in grams/meter on kilograms/thousand meters. The linear density is measured under tension as specified in EN 2307.

There are other material combinations that can be manufactured such as polypropylene + polyester or Oceanic, Nylon, etc, but apart from what is shown in the table of the next page, any other raw material combination is manufactured upon any customer's demand.

TWISTED ROPES 3 & 4 STRANDS

Twisted ropes come from a long way back and until resent years, the only thing that has been evoluted was the material used, that changed from natural fibers to man – made ones. This change of fiber gave the construction higher strength and longer life.

Today, twisted ropes are preferred for most ****** applications because of their flexibility, knots made, splicing and easy handling in small diameters.

The 4 - strand ropes have a slightly firmer lay that the 3 - strand ones, since they are round ropes with more outside su***ce, more traction on sheaves and objects.

Our company produces twisted ropes with the following materials:

NYLON

• High tenacity yarns • High elongation characteristics • High stretch – high strength fibers

• UV resistant o Sinkable ropes

POLYESTER

• Excellent Fatigue life • Increased service life • Low stretch – high strength fibers

• Excellent weather & abrasion resistance • Sinkable ropes

OCEANIC

• Flat filaments, a mixture of polypropylene – polyethylene co-extruded • One of the strongest floating ropes • Reduced friction internal and external o Increased flexibility

• Easy handling • UV resistant

POLYPROPYLENE

• They can be of split film or monofilaments twines • Light weight o Waterproof • Low stretching at work load • Abrasion resistant • All strands of the rope can be double twisted

• Floating ropes

SIZAL & MANILA

• Made of high quality natural fibers • Hygroscopic • Friendly for environment

• Excellent weather & abrasion resistance

1. Materials: All the above mentioned materials form yarns that in turn are twisted into strands and are made exclusively of pure raw materials.

2. Diameter: The size of all ropes must always be considered as approximately for obvious reasons and is actually determined by linear density.

3. Linear density: Is considered standard and in the metric system measured in Kilotex (ktex) that is grams/meter or kilograms/1000 meters length.

All ropes have an extra U.V. protection additives, are made of high quality materials and are properly tested and certified.

Twisted ropes have different applications such as in agriculture, transport, gardening, household, decoration, sports, shipping, fishing etc. It is up to the user to choose the right rope suited for the application it is intended for.
