Steel Fabrication Industry Status

The status of the steel fabrication industry in the USA depends much upon the construction activity. The slowdown in the construction industry results in a slowdown in the fabrication industry. This is suggestive of the relationship between the two.   

The supply chain in this sector is dependent upon major players. The producers of steel, service centers involved in the storage and preprocessing to some extent, fabricators, and erectors.  

Steel Fabricators manufacture structural components used in the construction industry for buildings. They also fabricate components that are used in old buildings as replacements and addition. Hence the overall status of the fabricators is much dependent upon the construction scene in the USA. Though fabricators of steel also process parts of bridges and other sectors the heavy reliance is on construction. In the year 2006 to 2007, the building activity was at its peak which has now slithered down.   

Fabrication is a lengthy work with multitudes of processes, hence the cost of operations is high. The requirement for workers and skilled professionals is also high. The the impact on job scene is palpable whence the slowdown takes place. At peak total employment was over two million with more than 2500 companies participating.

From total revenue of twenty billion dollars, the industry in 2018 is projected to grow by 4 to 5 % which is not very encouraging.

New Fabrication Technologies

As an industry advances technology appears and it is always evolutionary. Those who do not keep in tandem with technological upgrades perish. Specific industries have always been subjected to research and development which leads to better technology holistically.

Some of the recent developments find space in my blog here. 

Electronic Beam Melting (& Selective Laser Melting) the former is used in the purification of metals with high melting points often used in making alloys used for fabrication. Both are used in the fabrication of complex alloys.   

Usually, free electrons in a vacuum are used to form a fine beam which is used for melting purposes. This is possible whence the beam collides with solid-state matter wherein the electrons are converted to heat for melting. The process finds multiple uses besides welding. This form of welding in industries began as early as the nineteen fifties.  

The heat generated at the target helps in the process of heating applications. Due to the vacuum, the transformation is pure or absolutely sterile. Using large vacuum furnaces and strong beams steel can be produced without any impurities. 

The technology can also be used to cut an accurate bore. The resulting finish is better than using thermal cutting processes. Computer-controlled systems aimed accurately at selected work site it is useful for annealing, hardening, and tempering. 

Using an additive manufacturing process material can be efficiently joined using 3-D model data. Due to the high cost, the technology is used for valued production only. One fine example is electronic beam free-form fabrication used for a net-like finish wherein less raw material and less finish is the net gain. 

The equipment used usually comprises the following:

  • The Electronic Gun.

  • Vacuum Chamber.

  • Positioning Mechanism.

  • Controlling Equipment.

  • Power Supply.

Crude Prices & Metal Fabrication

The industry is related and often works as a complex web. This is an ecosystem that requires deep dwelling in order to perceive the ups and downs possible while fixing the business strategies.   

From over a hundred dollars to around fifty dollars that have been the story of oil per barrel. For the global industry, this is like manna from heaven.  The cheaper the raw material the better it is for manufacturers - fabricators included. Not only the industry the falling prices have given consumers a big relief.    

The dropping oil prices initially did not affect projects from the oil and gas industry but are bound to impact negatively. Large projects from this sector will keep the metal fabrication industry afloat. The resultant benefit of reducing oil prices will definitely impact favorably. The increase in oil production at the country level will act as a balancing factor. 

The lowering of oil prices will negate the rising cost of labor and other manufacturing inputs as far as the fabrication sector is concerned. Oil is a major variable as far as metal fabrication is concerned. Steel is dumped at lower rates in the US aided by lower shipping costs.   

Though demand from the energy sector may make a substantial impact on projects the uptick in the construction industry will act as a great leveler. A bright future awaits fabricators in the USA.

Comprehensive Innovation : Metal Fabrication Industry

Like all segment  of  manufacturing, fabrication business cannot survive stagnancy. There has to be a constant effort to improve and innovate. This is vital for survival since all technology driven businesses lose foothold and their vital customer base if they are not keeping abreast with the latest. 

The metal fabrication industry has faced innumerable challenges since last two decades to keep pace with the constant changes taking place. The innovation drive is comprehensive ranging from latest tools and equipment to management practices, IT system up-gradation and shrewd marketing strategies. 

As businesses move overseas to cut costs the customer base in North America and other developed World faces extreme reduction. Lets face the truth, access to overseas marketing is not an act of compassion or piety it is the need of the hour.    

Hence constant innovations and new developments are the key to survival. Things do not end here cost cutting by managing expenses considered affordable in good old days since these are no more sustainable. In short maximising efficiency without sacrificing quality is essential.  

To constantly evolve core business strategies, analysis and research though imperative need assistance of out of the box thinking. Both online or digital marketing and extensive land based strategies have to be employed.

Far from days of complacency, outsourcing has made industrial reach global mush to our chagrin. A disappointing development  but this is going to stay, there is no short cuts except face strict competition.  Possibility of trade barriers to provide relief is a distant dream because businesses moving overseas - to repeat is a strategy that benefits the parent companies. To face cutthroat competition the enterprise needs to be the fittest. 

Nevertheless competition is overcome by some resident factors like distance, availability of high grade manpower with requisite expertise and work ethics. Local fabricators will always retain these benefits.  Nevertheless extreme disparity in manufacturing cost could be a great lever. Back to square one.       

Creating a sustainable paradigm to for long term success is the imperative using constantly evolving technology and requisite skill base effectively. New skills in work force and access to and utilisation of  contemporary methodology will keep the pot boiling. 

Regular up-gradation of fabrication shops along with procurement of new equipment and tools is the key to stay afloat. In metal fabrication operational technology means efficient core machinery. Albeit expensive this is a long term value addition for a winning strategy.

Steel Fabrication Equipment & Tools

The World has witnessed a complete revolution with the development of steel its emancipation from the mined ore and eventual refinement. The alloying technique has given birth to complex metals with varied properties. This has led to the development of complex components required to withstand extreme temperatures, stress and acquire properties that are required for a particular function in a specific environment.    

Steel is a derivative of iron which is found as ore in nature. The metal is used in fabrication but its parent iron is also used as such. Hence most fabricators are using all forms of metal including iron. 

On a fabrication floor, a number of equipment and tools are set up depending upon the designs to be executed to form an end product belonging to a particular segment.  For example, the fabrication of building components, complex machines, and infrastructure projects all are specific to the manufacturing industry. Hence fabrication is limited by scope to the area of the owner's expertise and capabilities. 

The equipment or tools range from small and simple to big and complex. The list is large as mentioned below. 

  • Lathes
  • Band Saws
  • Manual Rod Benders
  • Welders Kit 
  • Welding Machines
  • Cutting Machines    
  • Body Hammers   
  • Jet Milling & Drilling Machine
  • Shop Presses
  • Bench Presses
  • Pipe Notching Dyes

  • Hammers
  • Metal Shears
  • Sheet Metal Brakes
  • Iron Workers
  • Bending Brakes
  • Punch Press  
  • Frame Press
  • Metal Forming Hand Tools
  • Tool Stands  


Above are listed some of the tools and equipment which are part of the trade. The fabrication industry has given rise to large-scale simple and complex ancillary, tools and equipment manufacturing industry in the USA. With the rise in the economy which leads to an increase in steel fabrication and ironworks the related manufacturing also offers great potential to industry leaders.

Structural Steel - Product Reuse & Recycling

Structural Steel is used in construction with an added advantage over traditional construction methods. This form of construction is gaining ground day by day as the fabrication industry advances. The new technology uses lightweight structural steel to fabricate building parts. These parts are made in units and not at construction. Eventually, they are installed at the construction and fitted at suitable junctures on the building being built.    

Product Re-use

This is one of the greatest advantages of lightweight steel. At the end of its life, it can be reused as a new product in buildings under construction.  In case of re-use, no processing is involved.  The steel structures are reused more in some sectors than others.   

The discouraging factors are lack of standardization and difficulty in assessment of composition and quality after end-life dismantling from its earlier incarnation.   

Design for reuse

Use bolted connections this allows easy dismantling 
Provide easy access to connections 
Keep the steel free from coatings or coverings for proper visual assessment. 
Minimize the use of fixings to structural steel using clamped fittings.
Use long-span beams

Recycling and reuse enable the reduction of adverse impacts on the environment with added cost benefits. Steel is hundred percent recyclable and a high-end recovery rate has to be kept that way.

Scrap recycling is also on the increase as an eco-friendly practice.  During prefabrication raw material waste does occur but this can be easily collected and recycled.   

The two aspects combined are leading the World to more sustainable development.  

Factors That Influence Steel Price

Understanding the factors that play an important role in pricing and production is necessary for those in the fabrication industry.  The industry uses many types of metals derived from steel. Like any other raw material used in fabrication and manufacturing a number of factors are influential.   

 The factors affecting may not necessarily be local but nowadays global impacts are applicable to nearly all industries. Hence some of these are: 

OIL Prices  


Oil prices govern all industries that are energy-dependent directly or indirectly. More so the effect could be indirect because alternate energy production in a way is linked to oil prices. Fossil fuel is required during the production of steel hence high price means a high cost of production.     



Demand 



Both local and international steel demands affect the selling prices. It is a competitive industry and high or low demand has a definite impact on sales.   



Construction  



Steel in one form or other is required by the construction industry. Hence the demand for the raw material is directly in proportion to the construction activity. In recent times this industry is experiencing a boom in the US and many other countries of the World. 


New methodologies like the fabrication of lightweight steel to make building parts have further the demand. World over the steel fabrication business is on the rise. This is due to cost reduction and the long-term benefits of lightweight steel fabrication. Quick installation is another virtue due to which this technology is gaining ground.

Structural Steel Fabrication What it is?

Third in line after the producers and service centers are the fabricators.   There are more than two thousand five hundred steel fabricators in USA. There job to fabricate hot rolled structural steel into desired parts and supply them to building projects.  

Most of the fabricators are family owned enterprises with a long line of staff. Both skilled and semi skilled employees are required. Depending upon the scale of business up to hundred employees may be in the place. The projects handled may be for small store to large building projects like colonies, high rise skyscrapers and malls.

The detailed drawings or plan are always executed by licensed engineers or technicians. The structural components are based on design by experienced architects. The approved drawings are then set to work by steel detailers who refine the design to get the end product. These detailers may work directly with the staff or on sub contract where cutting drilling and welding leads to perfectly designed and accurate product.

Many fabricators provide in house erector or installation services. These vendors are more preferred since services obtained are under one roof.  The article makes structural steel fabricators tasks seem very simple but the complexities are enormous. Also rigid safety standard have to be pursued in US.           

Structural Steel Fabrication Industry in USA

Fabrication is a process which accords shape and size to an element made of metal. This involves a number of process and technology. With regular advancements in technology there is a paradigm shift taking place as to how the industry surface.

Steel fabrication is a large industry in USA is most active in construction work. The raw steel produces many parts of building like windows, gates, staircase grills and what not. Hence no building is complete without the involvement of structural steel fabrication and its installation. The process is not limited to building parts it plays a major role in large projects like bridges, railways and industry in USA.

The process envisages the following steps.

Hot rolled steel smelted using an electric arc furnace. The use if ferrous scrap results in recycled content of more than eighty percent. The produces is in shape of hot rolled structural shape - beams, angles and plates.
Hollow structural sections are also manufactured the producers.   

The service centers act as warehouse and are instrumental in initial processing before actual fabrication takes place.    

The fabrication by major companies involves detailed drawings, cutting, shearing, welding and bolting. The complex process is guided by drawing by structural steel fabrication engineers.
Installation on spot fitting, welding, bolting on the construction site is the last stage of action.

The production of hot rolled structural steel exceeds way beyond eight million tons in USA and is constantly increasing.  At present there are three major manufacturers in United States that account for more than ninety percent of the produce.  A large percentage of the produces is utilized in building work.
