HSS In the Wild Pt 2

HSS truly opens up the possibilities for architecturally exposed structural steel, allowing architects and structural engineers to meet the challenges of modern architecture and design the type of structures that break new aesthetic ground and enrich the public landscape. But it can also have everyday uses that are all around us – if you know where to look! In our continuing photo blog series, let’s take a look at more places where we discovered HSS in the Wild.

HSS In the Wild

Hollow Structural Sections (HSS) help engineers create some pretty cool things every day – from tall skyscrapers for us to live and work in, to dynamic bridges connecting us from to and fro. But HSS products aren’t always used in such large scale projects – in fact, HSS is all around us, every day! As I travel around, I take snap shots here and there of HSS In The Wild to show all the interesting uses and applications this versatile product can be used in. Atlas Tube produces HSS products up to 18x18 square 0.625 wall (along with the corresponding rectangles) and rounds up to 20”. Along with JUMBO HSS sizes beyond 18x18 square, it gives you the flexibility to let your imagination run wild and create whatever you want. What projects will you use HSS in next?

While it’s known for deep-dish pizza, blues music and the Super Bowl shuffle, we’re most proud of Chicago’s steel skyline and its use of hollow structural sections (HSS). Today, I want to provide you a little background on Chicago’s history of architecturally exposed structural steel and why it continues to be the material of choice for designers and owners.

Designing and Specifying: ASTM A53 vs. ASTM A500

If you have ever referred to the ASTM (American Society for Testing and Materials) standard documents used for steel design and construction, you’ll notice that ASTM A53 steel pipe designations are different than ASTM A500 round hollow structural sections and they are manufactured to meet different standards. While ASTM A500 is available in cross-sections matching each of the cross-sections for ASTM A53steel pipe, there are many more cross-sections available in A500.
