The Nargesa NF70 hot-forms decorative ends on round or square bar up to 20 mm and flat bar up to 40 × 10 mm, including arrow, flat, striated and pyramid ends. Changing the rollers also lets it decorate the middle of balusters, so it suits ornamental ironwork shops making railings and gates in volume.

Applications
The Nargesa NF70 is designed for ornamental and architectural metalworking where heated steel must be formed into consistent decorative ends, patterns or central details.
Typical applications include:
- Gates and entrance gates
- Fences
- Railings and balustrades
- Windows and doors
- Ornamental balusters
- Bed headboards
- Metal furniture
- Decorative panels
- Architectural ironwork
- Wrought iron components
- Ornamental forged ends
- Custom decorative steel profiles
Depending on the roller set installed, the NF70 can produce:
- Flat ends
- Pyramidal ends
- Striated ends
- Fishtail ends
- Decorative baluster centers
- Embossed ornamental patterns
- Custom profiles using specially manufactured rollers
The NF70 is particularly useful for fabricators that need to produce large quantities of matching ornamental components. Once the appropriate tooling, back-gauge position and machine settings have been established, the same operation can be repeated consistently across a production run.
For optimum results, the material must be heated to the appropriate forging temperature before being processed. Nargesa recommends its H1, H2 and H3 forging furnaces for heating material before forming.
Why Choose the Nargesa NF70?
The primary advantage of the NF70 is its versatility. By changing the forming rollers, one machine can produce multiple decorative profiles, reducing the need for separate machines dedicated to individual ornamental designs.
This makes the NF70 particularly valuable for ornamental metalworking businesses that produce a variety of gates, railings, balusters and architectural components. Standard tooling handles several common decorative ends, while optional and custom rollers allow the machine to be adapted to additional designs and specialized customer requirements.
The NF70 also provides a practical way to mechanize repetitive hot-forging work. Features such as the digital display, programmable turns and adjustable back gauge help operators establish repeatable settings, improving consistency between parts and reducing reliance on manual hand forging for high-volume production.
For shops producing ornamental steel components in quantity, the NF70 can produce thousands of parts during a working day under suitable production conditions. This helps increase output while maintaining consistent decorative profiles across larger production runs.

Frequently Asked Questions
What ends can the NF70 make?
With the standard rollers: arrow, flat, striated and pyramid ends. Optional rollers add trilobular, middle-marking and fishtail designs.
What power does the NF70 need?
Nargesa specifies a 5.5 kW (7 CV) motor on a 230/400 V three-phase supply. Nargesa asks customers to contact them about other voltages or single-phase. Confirm your shop’s voltage with BTH Sales before ordering.
What is the maximum bar size?
20 mm round or square mild steel and 40 × 10 mm flat bar.
Does it need a skilled smith?
Nargesa says any worker can run it without previous training and that thousands of parts can be made in a day.
How long does delivery take?
BTH Sales ships across Canada from St. Marys, ON. This machine has a 4–6 week lead time; contact us for an exact date.
