What Material are Cable Ties Made from? Plastic v Metal Cable Ties
Cable ties are predominantly made from plastic, metal, or a combination of both. Each material is engineered for specific structural properties, making the choice of material critical to the lifespan and safety of your installation.
Whether you're organizing home electronics or outfitting an offshore oil rig, the material you choose dictates the temperature range, tensile strength, and environmental resistance of your cable ties. In this guide, we untangle the technical differences between nylon and stainless steel to help you find the right fit.
Standard Nylon 6/6 Plastic Cable Ties
The standard nylon cable tie is manufactured from Nylon 6/6. This chemical designation refers to the specific number of polymer chains (synthetic polyamides) that make up its structure, providing an ideal balance of flexibility and high tensile strength.
Key Applications:
- General cable management and DIY projects.
- Gardening and domestic signage.
- Household and commercial organizing.
Nylon 6/6 is loved for its high resistance to tension and external agents, but it has specific limits regarding heat and UV exposure.
UV & Heat Stabilised Nylon Cable Ties
Standard nylon ties are rated up to +85°C. However, prolonged exposure to extreme heat can cause a standard polymer to lose its physical integrity.
UV and heat stabilised ties are manufactured with specially formulated stabilizers. This allows them to operate in environments up to +120°C (or +105°C for continuous exposure).
The addition of carbon black (minimum 2%) acts as a sunscreen, protecting the nylon from ultraviolet degradation—making these the perfect choice for continuous outdoor use and machinery-adjacent locations.
"When it comes to standard indoor cable management, Nylon 6/6 is the go-to material for a reason. It provides exceptional tensile strength while remaining flexible enough for quick, manual installation. For domestic projects or office cable routing where exposure to UV or extreme heat isn't a factor, standard nylon is the most durable and cost-effective choice available."
Stainless Steel (Metal) Cable Ties
When environments exceed the limits of plastic, 316 grade stainless steel is the required solution. These metal cable ties are generally fire-resistant, flame retardant, and capable of withstanding extreme vibration.
GTSE uses marine grade 316 steel because it contains molybdenum, offering the highest level of corrosion resistance in saline or chemically active environments. A protective chromium oxide layer prevents rust, even under sub-zero or high-heat conditions (+540°C).
PVC & Epoxy Coated Stainless Steel
For applications where you need the strength of steel but want to protect the surface of your cables from scratches, coated stainless steel ties are ideal.
- PVC Coated: Features a pure polyester coating that minimizes abrasion and provides a dielectric barrier. Operating range: -40°C to +150°C.
- Epoxy Coated: Offers similar high-strength properties with a thinner, UV-resistant coating that is low-smoke and halogen-free.

| 316 Stainless Steel | Operating temp -80°C to +540°C. Marine grade. | Oil rigs, aircraft, mines, and tunnels. |
| Coated Steel (PVC/Epoxy) | Abrasion resistant. Operating temp up to +150°C. | Heavy-duty maritime and industrial wiring. |
Frequently Asked Questions
What is the strongest cable tie material?
For absolute strength and durability, 316 grade stainless steel is the strongest material, offering significantly higher tensile strength and temperature resistance than any nylon variant.
When should I use coated metal ties?
Coated metal ties (PVC or Epoxy) should be used when you need to prevent the tie from scratching sensitive cable insulation or when a dielectric barrier is required between the metal tie and the cable.
Can nylon ties handles extreme weather?
Standard nylon will degrade in direct sunlight. Always select UV-stabilised nylon for outdoor projects to ensure they don't become brittle and fail due to polymer degradation.
