Branch bracing is the term given to the practice of stabilising or limiting the movement of a branch to prevent excessive flex in extreme weather. Branch bracing is also used in situations where the tree has branches above public space and falling branches pose a risk. If carried out correctly with a well-designed rope system the tree will retain natural and safe movement and allow for growth. The bracing is usually spliced around two, or some times more, opposing stems. These Synthetic systems should be checked periodically for wear and adjustment.

Ultra-high molecular weight polyethylene (UHMWPE, UHMW) is a type of thermoplastic polyethylene/ high-modus polyethylene. Being highly resistant to corrosive chemicals, self-lubricating, having low moisture absorption and being highly resistant to abrasion, it is perfect ballistic protection, defense applications, and increasingly in medical devices, sailing, hiking equipment, climbing, and many other industries. It is synonymous with and often referred to the brand names, Dyneema, commercialized in the late 1970s by the Dutch chemical company DSM, and Spectra, commercialized by Honeywell.

The longevity of a rope is dependent on many different factors, some of which can be impacted by the choice of fibers and construction at the time of purchase. Some of the factors that impact the longevity of rope are UV and chemical exposure, geographical environment, maintenance and the frequency of cycles (days of use). For example: A rope used to perform an operation on a job site where it is exposed to fine dust and dirt will have a fraction of service life of the same rope that is used to perform a similar task inside a warehouse/factory. Some fibers like Dynnema have an outstanding UV and chemical resistance while fibers like Aramids and Para-aramids have significantly reduced UV resistance and some fibers like PBO are required to be completely covered to protect them from UV and moisture. Each rope or cable will need care and maintenance to see the longest life.

Any fiber with a Specific gravity (relative density) less than 1.0 will typically float. Fibers like Dyneema (UHMWPE) 0.97 and Poly propylene 0.96 are the most common fibers used when making a rope that needs to float. Fibers can also be blended to achieve or coated to help with water repellency.

Elastic Stiffness (EA) is a calculation of E (Youngs modulus) x A (the cross-sectional area). The EA value helps our customers and their clients compare various ropes and cables that may have different strengths, construction methods or even material and diameter.
