There is a common misconception: sustainable steel is often seen as a niche product, suitable only for pilot projects. The reality, confirmed by Swiss Steel Group figures, is quite the opposite.

The industrial applications of Green Steel are now the invisible engine transforming the most demanding industries worldwide. Our goal is not only to produce steel, but to support our customers in developing sustainable end products while ensuring extreme mechanical performance.

Here is where Green Steel makes the difference:

There is no energy transition without steel.

• Wind power: The blades of modern turbines exceed 100 meters and, under full load, their tips travel at incredible speeds while being subjected to sudden gusts. Swiss Steel supplies special steels for gears, bearings and fasteners (bolts and fastening elements) capable of withstanding these enormous cyclic stresses.
• Hydrogen: It is the fuel of the future, but it is challenging (it can cause embrittlement). We offer specific steels not only for the use of hydrogen as a process gas, but also for the infrastructures required to transport and store it.
• Nuclear and hydropower: From dam valves to reactor safety components, we supply stainless steels and special steels for engineering applications that meet the most stringent global safety standards.

The mobility sector accounts for approximately 44% of production.

• Automotive: We are shaping the future of mobility by working closely with the R&D departments of major brands. The goal? Lighter and stronger steels to reduce vehicle consumption.
• Aerospace: Here, perfection is not an option, it is a necessity. An aircraft that must withstand acceleration from 0 to 260 km/h in just a few seconds (with a take-off weight of nearly 600 tons) requires materials with absolute reliability for landing gear and engines.

• Mechanical engineering: It represents 27% of our market. We supply steels for machinery that must operate 24/7 without downtime.
• Agriculture and construction: Earthmoving machines and tractors require steels with extremely high resistance to wear and impact.

Having a “Green” steel that performs like (or better than) traditional steel is a technological achievement. But how does this material reach Italian workshops that manufacture gears, molds or automotive components? This is where Bonomi Acciai comes into play. Our role is to translate the complexity of these sectors into precise, reliable service.

1. Certification and traceability for critical sectors
In nuclear or aerospace applications, documentation is as important as the metal itself. Bonomi Acciai does not simply deliver bars or blocks: we provide full data traceability. For customers operating in controlled supply chains, we ensure that material certificates clearly report Carbon Footprint values and the technical specifications required by the most stringent standards.

2. Just-in-time for automotive
The automotive sector does not wait. Our logistics are structured to meet the tight schedules of automotive component manufacturing (Tier 1 and Tier 2). Thanks to our warehouse and service center, we can supply Green Steel cut to size exactly when the customer’s production line requires it, avoiding costly and obsolete stock.

3. Consulting on new materials (e.g. hydrogen)
A large portion of our customers in mechanical engineering are now approaching the hydrogen or renewable energy markets. Often, they are unsure which steel grades are suitable to prevent hydrogen embrittlement or corrosion in marine environments (offshore wind). Our technical department guides them in selecting the most suitable Swiss Steel grade, avoiding costly design errors.

4. Tooling: longer-lasting molds
For the “Tool and Die Making” sector, Green Steel means durability. We offer mold steels (for plastics or die casting) that ensure longer service life. A mold that lasts longer is, in itself, both an ecological and economic choice for the customer.

From the bolt of a wind turbine blade to an aircraft landing gear, passing through the tractor in the fields: Green Steel is not the future, it is the present of industry. Bonomi Acciai is the partner that brings this technological innovation directly into your production, ensuring that sustainability goes hand in hand with reliability.
