6×37 Steel Wire Rope Overview
GUANGTONG METAL manufactures and supplies 6×37 steel wire rope for industrial lifting, hoisting equipment, winches, construction machinery, rigging, and general engineering applications.
Our carbon steel wire rope is available in three surface finish options: Bright (Ungalvanized), Electro-Galvanized (EG), and Hot-Dip Galvanized (HDG), subject to confirmed production specifications.
The 6×37 class is commonly associated with multi-wire, six-strand rope constructions designed to provide suitable flexibility and bending performance for specified industrial applications.
As part of our Carbon Steel Wire Rope range, GUANGTONG METAL supports customized specifications, OEM manufacturing, bulk orders, and international wholesale supply.
6×37 Steel Wire Rope Construction
The 6×37 steel wire rope belongs to the six-strand wire rope family.
In a conventional 6×37 construction, six outer strands are laid around a central core, with each strand containing multiple steel wires.
The designation may also be used commercially for a broader construction class. Therefore, the exact strand arrangement should be confirmed according to the relevant technical specification.
Key Construction Features
- Six-strand rope design
- Multi-wire strand construction
- Fiber core or steel core options
- Different diameter and strength grade options
- Suitable flexibility for specified industrial applications
- Available with different surface finishes
Compared with many 6×19 class constructions of otherwise comparable diameter and core design, ropes in the 6×37 class generally use smaller individual wires and can provide greater flexibility.
However, flexibility, abrasion resistance, fatigue performance, and breaking force depend on the exact construction and manufacturing specifications.
For applications where relatively large outer wires and abrasion resistance are priorities, customers can also consider 6×19 Steel Wire Rope.
For other flexible multi-wire constructions, explore 6×36WS Steel Wire Rope.
Surface Finishes: Bright, Electro-Galvanized & Hot-Dip Galvanized
GUANGTONG METAL supplies 6×37 carbon steel wire rope with different surface finish options to meet industrial purchasing requirements.
1. Bright (Ungalvanized) Steel Wire Rope
Bright steel wire rope is manufactured without a zinc coating.
It is commonly selected for industrial applications where corrosion protection is managed through lubrication, maintenance, operating conditions, or other specified protective measures.
Key Features:
- Uncoated carbon steel surface
- Suitable for specified industrial and mechanical applications
- Available with different rope core options
- Requires appropriate corrosion protection and maintenance
2. Electro-Galvanized (EG) Steel Wire Rope
Electro-galvanized steel wire rope is manufactured using steel wires with an electrolytically deposited zinc coating.
GUANGTONG METAL offers electro-galvanized wire rope with a specified zinc coating mass of 10–50 g/m², subject to diameter, wire specifications, and production confirmation.
Electro-galvanizing can provide a relatively smooth and uniform surface appearance while offering additional corrosion protection compared with uncoated carbon steel.
Key Features:
- Electrolytically deposited zinc coating
- Specified zinc coating mass: 10–50 g/m²
- Generally smooth surface appearance
- Additional corrosion protection compared with uncoated steel
- Suitable for specified industrial environments
- Custom coating requirements subject to production confirmation
3. Hot-Dip Galvanized (HDG) Steel Wire Rope
Hot-dip galvanized steel wire rope is typically manufactured from steel wires galvanized through immersion in molten zinc before rope assembly.
GUANGTONG METAL offers hot-dip galvanized wire rope with a specified zinc coating mass of 80–300 g/m², subject to diameter, applicable standards, and manufacturing confirmation.
The higher coating mass available in these hot-dip galvanized options can provide additional corrosion protection in suitable outdoor and industrial environments.
Key Features:
- Hot-dip zinc coating
- Specified zinc coating mass: 80–300 g/m²
- Suitable for specified outdoor and industrial applications
- Additional corrosion protection compared with uncoated steel
- Coating specifications according to customer requirements
- Available combinations subject to production confirmation
Surface Finish Comparison
| Feature | Bright | Electro-Galvanized | Hot-Dip Galvanized |
|---|---|---|---|
| Surface Treatment | Uncoated | Electroplated zinc | Hot-dip zinc |
| Zinc Coating Mass | None | 10–50 g/m² | 80–300 g/m² |
| Corrosion Protection | Requires other protection | Additional zinc protection | Additional zinc protection |
| Surface Appearance | Uncoated steel | Generally smooth | Depends on process |
| Typical Applications | Industrial machinery | General industrial applications | Outdoor and industrial applications |
| Coating Requirements | Not applicable | According to specification | According to specification |
Important: Zinc coating mass is only one factor affecting corrosion resistance. Actual performance depends on coating quality, environmental exposure, lubrication, maintenance, and operating conditions.

Fiber Core (FC) vs Independent Wire Rope Core (IWRC)
The core type influences the flexibility, structural support, and operating behavior of 6×37 steel wire rope.
Fiber Core (FC)
A fiber core provides central support for the outer strands and can contribute to the rope’s flexibility and handling characteristics.
Fiber-core constructions may be considered where equipment specifications and operating conditions permit their use.
Independent Wire Rope Core (IWRC)
An independent wire rope core consists of a separate steel wire rope positioned at the center of the main rope.
Compared with otherwise similar fiber-core constructions, IWRC ropes generally provide greater resistance to crushing and improved structural support.
Core selection should be based on the intended application, minimum breaking force, operating loads, and equipment requirements.

Applications of 6×37 Steel Wire Rope
Cranes and Hoisting Equipment
Certain 6×37 rope constructions may be selected for crane and hoisting applications when the rope meets the required mechanical properties, equipment specifications, and applicable safety requirements.
Winches and Pulling Equipment
Used in specified winch systems and mechanical pulling applications requiring defined rope strength and bending characteristics.
Construction Machinery
Suitable for selected construction equipment and engineered mechanical systems.
Industrial Rigging
Used in general industrial rigging applications where the rope construction and technical specifications meet operating requirements.
Engineering and Mechanical Systems
Considered for mechanical systems requiring a six-strand rope with defined flexibility and load-bearing characteristics.
Safety Note: Wire rope used for lifting or other safety-critical applications must meet the relevant equipment requirements, applicable standards, and safety factors. Not every 6×37 configuration is suitable for every lifting application.
