To what extent can steel members from a demolished building be reused?

If the chemical composition and strength grade of the steel member is known beyond doubt then the member can be reused at that grade. Otherwise the member is treated as if it were in the lowest strength category and can be reused at that grade. The GBCA Green StarTM credits encourage the accurate identification of steel members in new construction to enable reuse, taking advantage of the right grade at a later date with confidence.
