4" DIA & 5" DIA FENCE POSTS GRADE 50 YIELD
4" DIA & 5" DIA FENCE POSTS GRADE 50 YIELD
(OP)
I AM ESTIMATING A PROJECT WITH A SECURITY FENCE THAT CALLS OUT THE POSTS TO BE 4.5" DIA AND 5" DIA x 3/8" WALL THICKNESS AND GRADE 50 YIELD STEEL. THE SPEC SAYS USE HDGALV PIPE CONFORMING TO ASTM F1043. I CAN'T FIND A STEEL PIPE PRODUCT THAT MEETS ALL THESE CRITERIA. I CAN FIND X-STRONG 5" PIPE THAT IS 3/8" THICK BUT IT IS GRADE A53 WHICH I THINK IS LESS THAN 50KSI. PLEAE HELP IF ANYONE KNOWS THE AVAILABILTY OF WHAT IS SPECIFIED.
THANKS
THANKS

I don't have the black book with me (going from a green book), but it looks like A618 has a 50 ksi yield (available in mill quantities only).
RE: 4" DIA & 5" DIA FENCE POSTS GRADE 50 YIELD
Grade 50 probably means ASTM A500, Grade C (50 ksi yield stress).
So, under ASTM A500 this would be:
HSS5.000x0.375
and
HSS4,500x0.375
The terminolgy 'strong, extra strong, etc.' applies to Grade A53 steel (which is 35 ksi yield), which is the old standard pipe designation (schedule 40/80 pipe).
If concerned on availability, go to AISC.org and click on 'steel availability' tab to see what's available.

I don't think A500 Gr. C (with 50 ksi yield) is available for rounds. It's available for square and rectangular.
The A500 Gr. C for rounds is 46 ksi.
