Guardrail posts W6x9 vs W6x8.5

Question
State	NE
Description Text	I see the W6x9 used on some installations & W6x8.5 used on SRT & ET PLUS end treatments. I thought I saw some W6x8.5 in the testing but don’t recall one off the top of my brain. Can the W6x8.5 be used as standard line posts in the MGS system?

Response
Response (active)	The W6x9 and W6x8.5 steel sections can be used interchangeably as line posts within the Midwest Guardrail System. Over the years, our MGS testing programs have utilized both sections. In the back of the more recent MASH crash test reports, you will find the actual material specifications and mill certifications which specifically identify which was used, including the material strength.
