Structural steel fabrication is the process of transforming raw steel into structures, products or components that can be used in construction or other industrial applications. Structural steel fabricators create a variety of steel beams, girders, decks and columns, among other things, that are used in a wide range of construction projects. So, if you are looking to get involved in the construction industry or just want to know more about steel beam fabrication, then this article is for you.

The tallest skyscraper in Singapore is currently the Guoco Tower, measuring 284 m or 931 ft but that could change as Skidmore, Owings & Merrill (SOM) has revealed plans for a new mixed-use building that would reach 305 m or 1,000 ft. It will be more than just a building as this proposed skyscraper is inspired by bamboo forests with ambitions for a healthier work environment using special materials while reducing its carbon footprint.
Effective structural design is challenging as the process requires an engineer to carefully consider loads, stresses, and forces at every step. They must also think about the environment in which it will be built and how it might affect other nearby structures. In this article, we share a few of the most important structural design considerations an engineer should keep in mind at all times. But first, let’s recap what exactly is meant by structural design.
Whether it’s wind power, hydrogen or electric vessels, decarbonising efforts in the maritime sector are reaching new heights. Among the latest developments is the new Alte Volare electric hydrofoil concept from British superyacht tender specialists, Cockwells. Here’s what we know.
Deep hole drilling is a machining process that can produce holes up to ten times deeper than the diameter of the hole and is suitable for a variety of metals, including the strongest of superalloys. Deep hole drilling services require special tools and setups to deliver high-pressure coolant, cleanly evacuate chips and reach the depth-to-diameter. Deep hole drilling, also known as gun drilling, is a highly-specialised machining operation that only a few engineering companies can perform, including PRV Engineering. Here is a closer look at some of the processes, applications and pros and cons.
General Dynamics Land Systems (GDLS) unveiled its impressive AbramsX battle tank technology demonstrator at the AUSA 2022. According to former military officials, it is the most significant upgrade of American military tank technology since the early days of the Cold War. While the AbramsX battle tank refers to the Abrams tank family, it’s more of a concept of the future generation of the main battle tank to nullify new threats the modern battlefield brings.
Is fusion energy the future? Based on recent developments from organisations across the world, it is certainly more of a possibility than just a few years ago. A nuclear fusion reactor that generates more energy than it consumes could pave the way for large-scale clean energy production. After all, that’s what defines a nuclear fusion plant, according to CFS. Let’s take a quick look at STEP and ARC fusion reactors with a brief overview of the SPARC project.
STEP Reactor For Fusion Energy
Spherical Tokamak for Energy Production, STEP for short, is an ambitious programme initiated by the UK government to design and construct a prototype fusion power plant. The goal is to create a reactor that could generate carbon-free fusion energy within two decades.
The STEP reactor is a variant of the basic tokamak reactor using magnetic fields to confine and heat a plasma of hydrogen atoms until they fuse together, releasing huge amounts of energy. Using a process called electron cyclotron resonance heating, it would also be more efficient than current designs as microwaves heat the plasma directly which means lower energy loss as heat.
While earlier fusion reactors were large and expensive, the STEP design has a diameter of around 10 m, making it relatively small compared to ITER (International Thermonuclear Experimental Reactor). This greatly reduces the cost but also puts higher stress on the applied materials.
ARC Reactor For Fusion Energy
The ARC (Affordable, Robust, Compact) reactor is a smaller and simpler design than STEP. It is being developed by a team of scientists from MIT (Massachusetts Institute of Technology) and Commonwealth Fusion Systems. The name and design were inspired by the fictional Arc Reactor built by Tony Stark, Marvel’s Iron Man, who attended MIT in the comic book series.
The ARC reactor is based on the tokamak design, which uses magnetic fields to confine a plasma of hydrogen atoms. They are working on the way to generate magnetic fields using rare-earth barium copper oxide (REBCO) high-temperature superconductor magnets This material enables higher magnetic field strength to contain heated plasma in a smaller volume.
The ARC reactor would also be more efficient than current tokamaks thanks to its innovative design, which would allow it to operate at higher temperatures. The first machine planned for this project is a scaled-down demonstrator called SPARC (as Soon as Possible ARC). If successful, SPARC would be the first device capable of “burning plasma” where heat from all the fusion reactions provides continuous fusion energy without adding extra energy.
Achieving “Burning Plasma” With SPARC
The inner workings verifying that SPARC will achieve net fusion energy have been peer-reviewed and published in the Journal of Plasma Physics. These are the first peer-reviewed papers from a private commercial fusion venture demonstrating that a small fusion device will produce net energy during an operation where the plasma produces more fusion power than it needs to start and maintain the process.
A major benefit of SPARC over ITER is that SPARC’s plasma will be confined by high-temperature superconducting magnets which have only become commercially available in recent years, long after ITER was first conceived. These magnets can produce significantly more powerful magnetic fields than ITER’s — 21 teslas from SPARC compared to ITER’s 12. To put that into perspective, the Earth’s magnetic field ranges from 30 millionths to 60 millionths of a tesla.
Nuclear Fusion Could Help Meet Global Climate Targets
Fusion energy has the potential to provide an abundant, safe and clean source of energy. The STEP and ARC reactors are two promising designs for making fusion energy a reality. If successful, these reactors could help to meet global climate targets and provide a major boost to the fight against climate change.
In case you missed it, we published an interesting article recently about the UK government planning to build a new nuclear fusion plant at West Burton, Nottinghamshire. It highlights how the plant will work, the benefits of fusion energy and whether it is safe.

Of all the green energy projects across the globe, few promise as much as the world’s first commercial nuclear fusion power plant in Nottinghamshire. There are also plans to sell the technology worldwide which could prove particularly beneficial to the UK’s export market.
Industrial spray painting may not involve creating works of art but it still requires a high level of skill to perform the job well. Industrial spray painting works with several types of liquid materials including certain paints, stains and primers. Among the greatest benefits of commercial spray painting is the high degree of control and even finish on all types of surfaces.
Plasma cutting has been in use since the 1960s and is still the preferred method for automotive repair shops, fabrication shops, industrial construction sites and salvage operations. This is largely due to the high speeds and precision cuts these machines can achieve.
While it was rather time-consuming and expensive in the early days, advancements in technology and engineering techniques made it a more user-friendly, economical and productive method. In this article, we discuss different plasma cutting methods, how it works, some of the applications and pros and cons.
