Stainless Steel Earth Rods
Generally, stainless steel earth rods provide a durable earthing electrode for electrical installations where corrosion resistance is an important consideration.
Specifically, the ER-SS range uses 316 stainless steel and a threaded sectional design. Each rod has a tapered end to assist driving, while compatible couplers allow additional rod sections to be added for deeper earthing installations.
Indeed, 316 stainless steel is commonly used in earthing systems exposed to corrosive soils or environments where galvanic corrosion between dissimilar buried metals may be a concern.
316 Threaded Earth Rod Features
- 316 stainless steel construction
- Threaded sectional design
- Tapered driving end
- Suitable for deeper earthing installations
- Compatible with one-piece stainless steel couplers
- Available in 16mm / 5/8″ diameter
- Available in 19mm / 3/4″ diameter
- Lengths up to 3000mm
- Suitable for electrical and industrial earthing systems
- Good corrosion resistance in demanding environments
The threaded design allows rods to be joined as the installation progresses rather than relying on a single fixed-length electrode.
Available ER-SS Sizes
Engineering Supplies stocks the following sizes:
| Part Number | Diameter | Length |
|---|---|---|
| ER-SS1624 | 16mm / 5/8″ | 2400mm |
| ER-SS1630 | 16mm / 5/8″ | 3000mm |
| ER-SS1930 | 19mm / 3/4″ | 3000mm |
Currently, these are the stocked sizes shown in the Engineering Supplies catalogue and live product range.
Threaded Earth Rod Installation
Where additional depth is required, therefore, installers can join multiple rod sections using the correct stainless steel coupling.
Accordingly, use the matching Stainless Steel Earth Rod Couplers (316) for 16mm / 5/8″ or 19mm / 3/4″ rods.
The couplers are designed specifically to join threaded stainless rods while maintaining alignment during driving. Indeed, the coupler range includes ER-SSC16 and ER-SSC19, both 70mm long.
Typical Earthing Applications
Stainless steel threaded rods suit applications including:
- Electrical earthing systems
- Mining installations
- Utilities
- Industrial facilities
- Infrastructure projects
- Switchyards and substations
- Lightning protection systems
- Corrosive soil environments
- Coastal or aggressive environments
- Deep earth electrode installations
Therefore, always select the rod material, diameter, depth and connection method to suit the electrical design and site conditions.
Stainless Steel or Copper Clad Earth Rods?
For many general earthing installations, Copper Clad Threaded Earth Rods generally provide a cost-effective option.
However, 316 stainless steel earth rods can be preferable where corrosion resistance or compatibility with nearby buried metals is a key consideration.
Therefore, the correct choice depends on soil conditions, electrical design, adjacent buried materials and the expected service environment.
