QINGDAO JINCHENG MARITIME has serial products including varieties of nylon, polypropylene filament, polypropylene, polypropylene /polyester mixed, polyester. It started a new epoch of rope and cable industry in the country and its products have advantages of reasonable braided structure, scientific technology, high strength, low elongation,wearing resistance, anti-corrosion and simple operation, it is particularly suitable to make large scale ropes and cables as well as anti -static ropes therefore they are well received by broad customers, The products are mainly used in fields of shipbuilding, ocean transportation, national defense and military industry, sea petroleum and harbor operation etc.

Key Features of Multi-Color Rope Spool (3-38mm Double Braid Nylon Rope) for Marine Use
This multi-color rope spool, featuring 3-38mm double braid nylon rope, is engineered to meet the rigorous demands of marine environments—blending structural robustness, marine-specific durability, and practical design. Its core features are as follows:

1. **Double Braid Nylon Construction for Marine-Grade Strength & Resilience**
The double braid structure (a braided outer sheath over a braided inner core) is a defining advantage for marine use:
- It delivers exceptional tensile strength and shock absorption—critical for withstanding dynamic marine forces like wave impacts, sudden wind loads, or vessel movement during mooring. Nylon’s natural elasticity further enhances this, as it stretches slightly to dissipate stress (e.g., when a boat jerks against a dock) without snapping.
- The dual braided layers also boost abrasion resistance, protecting the rope from wear caused by friction against cleats, winches, dock edges, or rough hull surfaces—common hazards in daily marine operations.

2. **3-38mm Diameter Range for Versatile Marine Applications**
The broad 3-38mm diameter span ensures the rope adapts to diverse marine tasks, from small-scale to heavy-duty:
- **Small Diameters (3-10mm)**: Ideal for lightweight marine uses such as tying fenders, securing small watercraft (e.g., kayaks, canoes) to docks, or as auxiliary lines for sail adjustments (e.g., trimming small sails).
- **Medium-Large Diameters (11-38mm)**: Designed for heavy-duty marine operations, including mooring medium to large boats, towing small vessels, serving as dock lines, or even as anchor lines for smaller watercraft. The larger sizes (25-38mm) offer maximum load-bearing capacity for commercial or recreational vessels requiring reliable securement.

3. **Multi-Color Design for Enhanced Marine Safety & Identification**
The multi-color feature is more than aesthetic—it solves key marine practicality and safety challenges:
- **Quick Identification**: Different colors can be assigned to specific marine functions (e.g., red for starboard dock lines, blue for port lines, yellow for anchor lines), eliminating confusion during fast-paced operations like docking or undocking.
- **Visibility**: Bright, distinct colors improve the rope’s visibility in low-light conditions (e.g., dawn, dusk, or fog) or cluttered marine environments (e.g., busy marinas with multiple ropes), reducing the risk of tripping, entanglement, or accidental damage to the rope.

4. **Nylon Material for Superior Marine Environmental Resistance**
Nylon is inherently suited for marine use, with properties that counteract harsh saltwater and outdoor conditions:
- **Saltwater & Moisture Resistance**: It resists corrosion, rotting, and mildew growth when exposed to saltwater or constant dampness—unlike natural fibers (e.g., cotton) that degrade quickly in marine environments.
- **UV Stability**: Nylon maintains its strength and flexibility even after prolonged sunlight exposure (a must for ropes left exposed on boat decks or docks), preventing brittleness or color fading that could compromise performance.

5. **Spool Packaging for Convenient Marine Storage & Handling**
The spool design addresses practical marine storage needs, ensuring ease of use and rope protection:
- **Tangle-Free Deployment**: The spool keeps the rope neatly coiled, avoiding knots or tangles that delay critical marine tasks (e.g., emergency mooring). Users can unspool only the length needed, reducing waste and mess.
- **Space-Saving Storage**: Spools fit compactly in boat lockers, storage compartments, or marina sheds—essential for vessels with limited space. The rigid spool also protects the rope from dirt, debris, or accidental damage during transport or storage, extending its service life.
