“IDST” in the context of Blok ‘N’ Mesh most likely doesn’t stand for a Blok ‘N’ Mesh-specific term at all; it’s almost certainly the well‑known UK slang acronym “If Destroyed Still True”.

There is no official Blok ‘N’ Mesh acronym list that defines “IDST” on their website or in their public materials. That means the phrase you’re seeing is probably:

  • A text/graffiti-style comment posted on a forum, social media, or in a discussion about Blok ‘N’ Mesh (e.g. temporary fencing, construction sites, etc.), using IDST as a standalone slang expression, not as a company term.
  • Or, in a purely technical context unrelated to slang, “IDST” could refer to the Inverse Discrete Sine Transform (a math/signals concept), but that would be strange in a Blok ‘N’ Mesh discussion unless it’s some engineering forum misuse or confusion.

What “IDST” usually means

In UK youth culture and online slang, especially in graffiti and text messages:

  • IDST = “If Destroyed Still True”
    Example: “Mark loves Kelly IDST” → “Even if this message is destroyed, it’s still true”.

Some people also use a variant meaning:

  • “If Deleted Still True” (same idea, adapted to online posts).

There is also a less common meaning:

  • “I Don’t See That” , but this is not the dominant usage in graffiti or forum culture.

Why it might appear with “Blok n Mesh”

“Blok ‘N’ Mesh” is a known manufacturer of temporary fencing and pedestrian barriers , operating in the UK and Europe. Discussions about them often happen on:

  • Construction forums
  • Site safety groups
  • Local community threads about fencing on streets or estates

If someone wrote something like:

“Blok n Mesh fences are everywhere IDST”

they’re likely just adding the slang “IDST” as a comment (e.g. “even if you delete this, it’s still true / you can’t deny it”), not quoting a company term.

Quick summary

  • IDST in general slang = “If Destroyed Still True” (or “If Deleted Still True”).
  • There is no evidence that Blok ‘N’ Mesh uses “IDST” as an internal acronym or official term.
  • In the phrase “idst blok n mesh”, IDST is almost certainly slang attached to a comment about Blok ‘N’ Mesh , not a definition from the company itself.
