Made from natural hard fibres Manila & Sisal Ropes are the best of their kind in India. Made in accordance to rigid 1.5.1. specifications. Ropes 1jre available in sizes varying from 4mm. dia to 76 mm. dia in Manila (Grade - I, II & III) and Sisal (Grade 'A'). Their distinct and superior characteristics, offer both high breaking strength and maximum flexibility in use. They have a wide range of applications in various industries.
Material Handling
Manila and Sisal Ropes are used. extensively in engineering industries and at construction sites for material handling. Due to their heavy load lifting capacity these Ropes are well suited for hauling and cargo lifting operations.
Ports And Shipping
Manila Ropes of various diameters are widely used for towing, mooring and dry docking by Port Trusts and Shipping Industries. Manila Ropes offer excellent resistance to action of water and marine organisms, and are therefore ideally, suited in the Marine Industry.
Transport
Sisal Ropes find wide applications in the domestic transport industrY for safe handling of cargo. Due to their excelient shock absorbing capability Ropes are acknowledged to be the most reliable for this end use.
Weights are subject to +- 5% maximum variation. Tensile strengths are approximately average and the minimum shall be within minus 1O% of the listed value. The values shown above are for regular aly ropes
