Australian Steel Standard 1

[Veer007]

Hey Guys,

Do anyone know what's the standard material for Steel Shapes(I section, HSS section, Plates Channels Angles Anchor rods) as per Australian code. Also high strength bolt grade? I'm familiar with AISC, but don't know much about Australian code. If I got equivalent material for comparison it would be better.

Thanks in advance!!

Structural bolts are typically grade 8.8 to AS/NZS1252.

Most hot rolled shapes are specified as grade 300 material, actual yield strength depends on the thickness of web/flange, etc.

CHS/SHS/RHS are typically grade 350, 350MPa yield strength. Some can be sourced in dual grade 450MPa material (usually smaller sizes). This complies with all the material limitations of grade 350 but has a higher yield strength.

Welded sections, plates can be anything you want, typically fabricated from grade 300/350 to 400 plate.

Lookup standards AS/NZS3678 & AS/NZS3679 & AS/NZS1163.

The Australian steel code has a table in it denoting the typical material grades and subgrades that comply and relevant standards. There is no direct comparison to American grades/sections unfortunately.

If its a project supplying American sections to Australia be aware it may not comply without testing and qualification by a suitability qualified metallurgist. Until that is undertaken it would be treated as unidentified steel, look that up in AS4100 for definition. Basically you'd be better using a local fabricator and supply chain. I've been involved in a few foreign steel supply substitutions and it never works out to be plain sailing.

AS & NZ standards are based on Australian/New Zealand fabricated plate and sections. Some substitutions for different international standards are provided for Japanese and British and European material/grades/codes.

Refer to these that cover the standard sizes:

Thanks Guys, I was expecting only structural steel grades and specifications UNO.

Thanks in advance!!

 

[Veer007]

1. For 300PLUS® sections the tensile strength (fu) is 440 MPa.
2. For Grade 350 sections the tensile strength (fu) is 480 MPa

These are the material for structural steel, they means ultimate tensile strength right?

Thanks in advance!!

 

[Veer007]

So far, I found this from net source

Thanks in advance!!

 

[Veer007]

What would be the grade of 6M24 HD Anchor rod grade UNO?

Thanks in advance!!

 

[Agent666]

Assume G4.6 I guess uno.

 

[Agent666]

These are the material for structural steel, they means ultimate tensile strength right?

Yes f_u is the ultimate tensile strength.

 

[Veer007]

What's the difference between grade 8.8 and 8.8/s? both are same? "S" means snug tight, right.

Thanks in advance!!

 

[Agent666]

Yes '/S' is just snug tight, same bolt. /xx is just the tightening method.

 

[Veer007]

Can I follow workable gauge for beams similar to AISC ? Or any details there for Australian?

Thanks in advance!!

Are you in the US, but working on an Australian project? I think you shall use the standard based on the host area/local the project is to be carried out. It will cause a lot of headaches and mistakes by conversions back and forth. But, if agreed by both parties, you shall stick to the selected standard consistently throughout.

 

[Agent666]

For hot rolled I sections 70/90/140 are preferred. But really anything that works, it's not 'codified'.

 

[Veer007]

Thanks agent.. Is M24 rod actual diameter is 24mm? In Australia also for rods grade 300 is acceptable? I have to use this rods for both turnbuckle and Anchor rods..

Thanks in advance!!

You seem to be asking many many questions and relying on the good nature of people here to spoon feed it all to you. It would help us in answering these question if you tell us why you are designing something to Australian standards with AISC materials or AISC methods. Where are you working from Asia? Somewhere else?

If grade 300 threaded rod turns up to a site in Australia people would scratch their heads and ask what the hell are you supplying.

 

[r13]

From somewhere in Asia?!

 

[Veer007]

Material for hot-rolled sections is 300, right for Australians.

Guys, I'm from Asia. I know AISC/CISC standards a little much, so I just get an idea if I got some comparison, nothing else.

250 grade for plates, 300 grade for hot-rolled sections, and 350 grade for hollow sections per AS/NZS standards

Thanks in advance!!

 

[Veer007]

I just agreed to work for them, I believed that the engineering concept is the same all over the world So that I can do some work if we know some basics, Isn't fine?

Thanks in advance!!

Working For fabricators, to design connections and detail the structural steel

Thanks in advance!!
