3 Benefits to Using Steel Windows

Posted on November 29, 2011 by Reda Abouleish

steel-stainless-windows-benefits-tips-barsSteel is a material that works with modern or classic building designs.  Architects, builders and designers are choosing steel windows over other materials but why.  What makes steel windows more beneficial than the rest for commercial structures, hospitals, schools and homes?  Here are three advantages to using steel windows.

Steel Windows Last

If you compare aluminum versus steel windows then steel windows are easily the stronger and more durable of the two.  A steel window is approximately three times stronger than aluminum.  It does not crack with age or disintegrate over time.  It produces solid windows able to hold an immense amount of weight and size offering breathtaking outdoor views that may otherwise not exist at all.

High Fire Rating

When a builder is designing a structure he/she must keep in mind the required building codes of fire windows.  In many cases, city codes require fire rated steel windows to be used, especially when related to specific structures. Check with your building codes for details.

How are Fire Windows Rated?

Fire windows are measured by the duration of time it takes to protect a building from flames.  A fire window with a high rating is considered better protection for occupants and those around or near the building.  Steel windows prevent further tragic situations from occurring for steel windows do not break, melt or cause a back draft.  This significantly decreases the danger people and firefighters face during such disasters.


As mentioned in the introduction, steel windows can be used for a wide array of styles and looks.  You can go extremely modern or traditional.  It does not matter what route you choose for you are able to customize your orders into whatever form, shape, style needed to complete your design.

Choose Steel to Design with in 2012

Posted on November 23, 2011 by Reda Abouleish


When designing a structure many engineers are turning to steel.  It is a lightweight material packed with durable, reliable strength that has been used for eras.  Drive around in your area and look around.  There are skyscrapers, concert stadiums, sports venues and home dwellings all made from stainless steel.  So why do so many people choose stainless steel versus other materials?  Stainless steel allows a builder’s imagination to run free without any limitations.  You are able to choose from a wide array of options making your vision come together right before your eyes.

Customize Your Stainless Steel Structure

There are an endless number of options available when designing with steel.  You can choose from different colors, various shapes, windows and more.  The key to finding out what options are available is to talk to a stainless steel sales representative with the knowledge and experience to provide you with the help in understanding and creating the best building design matching your needs.  It is a valuable asset to have someone on the other line providing you with solid advice.

Designing your commercial or personal property should be fun!  Find a stainless steel supplier that hires experienced and trained staff available to guide you through the process.  It does make a significant difference having someone with a vast supply of knowledge from the steel supplier on your team.

2 Benefits to Building with Steel

Posted on November 21, 2011 by Reda Abouleish


Builders are always thinking of new ways to create sustainable and durable structures.  They are thinking of ways to keep the environment safe while matching the needs of consumers.  Going green is at the forefront of their mind but so is cost.  With the economy in a slump, builders are trying to find cost-effective means to deliver a high quality product without breaking the bank.  A material that assists builders in addressing these concerns is steel.


Steel is a material that lasts through the most extreme temperatures and weather.  There is little to no risk of a building falling apart when natural disasters strike.  The steel remains intact providing the client with peace of mind.  Additionally, when choosing stainless steel there is no risk of the material decaying like wood or attracting termites or rodents.  Stainless steel is a solid choice when building different venues, living spaces, office buildings, medical centers, storage areas and more.

Cost Effective

Working with steel decreases your overall costs.  It reduces the amount of subcontractors needed to work on your project.  You do not need roofers, framers and siding contractors.  This keeps your projected completion time on track.  The less people to worry about the better you are at time management.  The delays are minimized ensuring you are not wasting money on unexpected additional time and labor.  This is a significant advantage over other materials.

3 types of Stainless Steel

Posted on November 17, 2011 by admin

The 3 main types of stainless steel are austenitic, ferritic, and martensitic. These three types of steels are identified by their microstructure or predominant crystal phase.

Austenitic steels have austenite as their primary phase (face centered cubic crystal). These are alloys containing chromium and nickel (sometimes manganese and nitrogen), structured around the Type 302 composition of iron, 18% chromium, and 8% nickel. Austenitic steels are not hardenable by normal heat treatment, yet they can be work hardened. They are also non-magnetic. The most familiar stainless steel is probably Type 304, sometimes called T304 or simply 304. Type 304 surgical stainless steel is an austenitic steel containing 18-20% chromium and 8-10% nickel.

Ferritic steels have ferrite (body centered cubic crystal) as their main phase. These steels contain iron and chromium, based on the Type 430 composition of 17% chromium. Ferritic steel is less ductile than austenitic steel and is not hardenable by heat treatment.

The characteristic orthorhombic martensite microstructure was first observed by German microscopist Adolf Martens around 1890. Martensite is a hard transformation product, technically considered a supersaturated solution of carbon in iron. This is characterized by an acicular (or needle-like) pattern in the microstructure in both ferrous and nonferrous alloys. Martensite can be transformed into austenite when the steel is quenched and cooled below 450 degrees Fahrenheit resulting in a hardness varying from 30 to 68 Rockwell, depending on the carbon content.  It also may be tempered and hardened. Martensite gives steel great hardness, but it also reduces its toughness and makes it brittle, so few steels are fully hardened.

There are also other grades of stainless steels, such as precipitation-hardened, duplex, and cast stainless steels.
