Martifer

Martifer is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Martifer rather than just read about it. In short: Martifer SGPS, S.A. is a family group based in Oliveira de Frades, Portugal, with over 3,000 employees, focusing its activity on the metal construction and renewable energy areas. The company launched its first operations in 1990 in the metal structure industry.

Key takeaways

Martifer belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Martifer to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Martifer from memory before moving on to harder problems.

Reference excerpt

Martifer SGPS, S.A. is a family group based in Oliveira de Frades, Portugal, with over 3,000 employees, focusing its activity on the metal construction and renewable energy areas. The company launched its first operations in 1990 in the metal structure industry. In 2004, it entered the renewables business, leveraging know-how from the metal construction operation to develop the energy equipment division. Martifer is a market leader in Iberia for metal construction, and aims to become the top player in other specific markets, namely Europe and Angola. In renewable energies, Martifer would like to become established as an integrated producer of turn-key solutions for the wind and solar segments. Furthermore, within renewable energies, Martifer operates as a promoter of electricity generation projects, with a portfolio of holdings in projects at different phases of development. Martifer SGPS, SA is the Group's holding company and has been listed on the Euronext Lisbon since June 2007. In 2008, its core activity operating revenues reached EUR 650 million. The main shareholder structure is made up of the founding partners, through I’M SGPS, S.A., and the Mota-Engil Group, both control approximately 80% of the company. In June 2009, Martifer and Hirschfeld Wind Energy Solutions, a part of Hirschfeld Industries in Texas, United States, announced a Joint venture for the manufacture of wind towers and related components in the United States. The project cost was estimated to cost $40 million US dollars to build a new facility in San Angelo, Texas. Production was originally expected to reach a capacity of 400 towers a year by 2013. However, the operation was unable to compete effectively in the very difficult pricing environment for wind towers in the 2009-2011 time frame and the investment failed to reach its objectives. On July 18, 2012, Hirschfeld announced that it had acquired the remaining 50 percent of the joint venture from Martifer for a small cash payment, and as of 2014, had converted the plant to build steel bridge structures. The last wind tower was produced there in 2012.

History The company was founded by two brothers, Carlos Martins and Jorge Martins in Oliveira de Frades, Central Portugal,. The enterprise has started with 18 employees. Today the group has worldwide 3,000 employees. Subsidiaries are in Spain (1999), Poland (2003), Romania (2005), Czech Republic (2005), Slovakia (2005), Germany (2005), Brazil (2006) and Angola (2006).

Worked examples

Example 1 — a first encounter with Martifer

Start with the simplest possible case. Write down what Martifer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Martifer before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Martifer ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Martifer

In research: Martifer appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Martifer in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Martifer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2007 initial public offerings, Bioenergy companies, Companies listed on Euronext Lisbon, so understanding it makes those chapters shorter.
In everyday life: Look for Martifer outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Martifer in simple terms?

Why does Martifer matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Martifer?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
