In modern electrical installations, safety, durability, and compliance with international standards are critical. At Deltafleks, we provide advanced solutions that ensure the integrity of your electrical infrastructure in both indoor and outdoor environments. One of the most reliable components in this system is the IMC (Intermediate Metal Conduit) — a high-performance conduit ideal for demanding installations.
In Turkey, cable routing in electrical installations has traditionally been done using PVC spiral, coil, or rigid PVC conduits. In industrial settings, metal pipes such as water pipes have commonly been repurposed. However, today’s systems increasingly rely on galvanized steel conduits, especially IMC types, which offer superior mechanical and environmental protection.
IMC conduit is a threaded galvanized steel pipe designed to protect insulated electrical conductors and cables. It features a hot-dip galvanized exterior and an interior corrosion-resistant coating for extended life. IMC is lighter than RSC (Rigid Steel Conduit)—about one-third less in weight—yet still provides strong mechanical performance.
Each IMC pipe is typically 3 meters long, comes threaded at one end, and has a coupling on the other. These conduits comply with UL 1242 and ANSI C80.6 standards and are approved under NEC Article 342. Additionally, IMC is listed as an acceptable grounding conductor in NEC Article 250.
IMC conduits combine strength, flexibility, and corrosion resistance, making them ideal for industrial and commercial environments. Key benefits include:
Lightweight yet durable steel construction
Hot-dip galvanized and corrosion-resistant inner coating
Easy to cut, bend, and assemble
Smooth internal surface for easy cable pulling
High impact resistance and fire safety
Excellent protection against electromagnetic interference
Cost-effective alternative to heavier conduit types
Typical applications include:
Industrial facilities
Office complexes and commercial buildings
Metro stations and public infrastructure
Workshops, skyscrapers, and ships
| Feature | IMC Conduit | RSC Conduit |
|---|---|---|
| Weight | Lighter | Heavier |
| Inner Diameter | Wider | Narrower |
| Installation | Easier to cut and bend | More labor-intensive |
| Cost | Lower | Higher |
| NEC Approval | Approved | Approved |
IMC conduits offer all the performance of RSC but with reduced weight, easier handling, and lower cost — up to 30% savings in total installation expenses.
IMC falls between RSC and EMT (Electrical Metallic Tubing) in terms of strength and weight. EMT conduits are not threaded and are used primarily in residential or light commercial applications where cables are exposed. They are not designed for high-impact areas or external use.
IMC conduits, on the other hand, are well-suited for service entry points, outdoor panels, and installations requiring robust protection and fire resistance.
At Deltafleks, we provide not only conduits but also a wide range of compatible IMC accessories, including:
Elbows
Couplings
Junction boxes
Bushings
Hangers and clamps
Adapters and connectors
Bending tools and installation kits
Together, these accessories create a seamless and professional conduit system, ensuring long-lasting and safe cable management.
Whether you're building a high-rise, outfitting a factory, or modernizing a commercial space, IMC conduits provide the strength, safety, and longevity your electrical system needs. Backed by international certifications and Deltafleks’ expertise, our solutions deliver exceptional performance under all conditions.
Choose Deltafleks for smart, reliable, and cost-effective conduit systems — engineered for modern infrastructure.
