brass/aluminum covers** or **Cerakote-coated covers**.
III. Core Advantages
1. **Durability**
- The metal boxes are made of **galvanized steel/316 stainless steel**, which is anti-corrosion and rust-proof; the floor box covers
have passed the **IK10 impact resistance test** and can withstand the of forklifts.
- Cerakote coating technology: Resistant to scratching and corrosion, extending the outdoor service life.
2. **Functional Integration**
- **Multi-service integration**: A single floor box can integrate power supply, network, and HDMI interfaces (such as the 665-AV series).
- **Flexible installation**: Supports embedded, flush, and poke-through installations, and is suitable for concrete, raised floors, etc.
3. **Certifications and Standards**
- In the North American market: UL Listed, CSA Certified, NEMA 3R/4X (outdoor), NEMA TS 2 (floor boxes).
- In the international market: IP66/67 protection level, in line with the IEC 60529 standard.
IV. Application Scenarios
| Scenario | Recommended Products | Advantages |
| Commercial Buildings | 664/665 series floor boxes | Wear-resistant in high-traffic areas, and the hidden wiring is aesthetically pleasing |
| Industrial Factories | Metal waterproof boxes (NEMA 4X) | Anti-corrosion and dust-proof, suitable for the power distribution of factory equipment |
| Municipal Engineering | Weather-resistant pole boxes (Red Dot series) | Waterproof and lightning-proof outdoors, supporting streetlight/traffic signal control |
| Home Decoration | 4-inch square metal boxes, Carlon plastic boxes | Low cost, easy to install, suitable for indoor switch/socket wiring |
V. Purchase Suggestions
1. **Environmental Requirements**
- In outdoor/coastal areas: Give priority to **316 stainless steel boxes** or **FRP materials**, equipped with IP67
waterproof covers.
- For high-traffic floors: Choose **Cerakote-coated floor boxes** (such as the 664-CI series).
2. **Functional Requirements**
- For multi-device integration: Choose **4-gang floor boxes** (such as the 665-CI), and reserve heat dissipation space.
- For embedded installation: Confirm that the size matches the bracket (for example, the 68 series needs to be used with
a pre-embedded metal frame).
3. **Compliance**
- For North American projects: Ensure that the products have **UL/cUL certifications**; European projects need to comply
with the **ATEX explosion-proof standard** (if applicable).
VI. Conclusion
Steel City electrical boxes have core advantages of **durability, integration, and standardization**, and they are particularly
outstanding in the fields of **outdoor protection** and **floor wiring**. Its product line covers from small-sized household
boxes to industrial-grade explosion-proof boxes, suitable for different scenario requirements, and it is one of the high-end
brands in ABB's electrical solutions.
