Silver Rope is a low cost synthetic fibre rope made from UV stabilised Polyethylene.
Silver Rope is a Polyethylene fibre rope, manufactured using a special extrusion process which gives the rope superior strength and a distinctive hairy appearance.
Silver Rope is strong and versatile, with excellent handling properties due to its surface characteristics. It is ideal for general and industrial applications, particularly in the marine industries where high resistance to abrasion is required.
Guaranteed Breaking Strength (kN)
|Approx mass/100m (kg)|
Some low cost Silver ropes tend to have lower mass per unit length. They may also have proportionately lower strength.
Note that the Working Load Limit will be less than the Guaranteed Breaking Strength by the Factor of Safety or Safety Factor. Local codes or standards may stipulate a Safety Factor to apply to specific rigging applications. In the absence of specific requirements, a Safety Factor of 5 could be used for dynamic rigging, and 3.5 for static rigging.

|Guaranteed Breaking Strength||The load or force stated by the rope manufacture as the rope's breaking strength when tested to failure in a new condition|
|Safe Working Load||The maximum load that may be applied under specific conditions of use to a crane, hoist, rope, chain, sling, or item of lifting gear|
|Safety Factor||The ratio of GBS to WLL|
|Sag||The maximum vertical deflection of the span below the straight line between the supports|
