3 or 4 Strands rope 

3 or 4 strands is the oldest and simplest rope  construction, consisting of 3 or 4 twisted strands  laid together. 3 or 4 strand ropes are hard wearing and easily spliced. 

Multiplait

Multiplait rope consists of 8 strands plaited in  pairs, each pair passing over one pair and under  the next. 4 ‘S’ and 4 ‘Z’ twisted strands make  Multiplait a torque balanced construction. It is  easily terminated and the twisted strands offer  good resistance to abrasion.

Braidline

Braidline rope consists of a braided core encased  in a braided jacket. The core and cover of the  rope each constitute about 50% of the total rope weight.

12 Strand Rope 

12 strand ropes consist of 6 “S” and 6 “Z” strands.  The configuration used is 2 strand passing over  2 strands and under 2 strands.  12 strand is torque balanced and its round profile  provides excellent abrasion resistance due to  greater surface contact.  A 12 strand construction offers higher strengths  over conventional constructions.
