Is anyone familar with Telling Industries, a manufacture of non-loadbearing structural framing (studs, etc)? They have been submitted and our project team is not familiar with them.
They are one of just a few companies producing light-gauge steel framing nationally. They also make proprietary slip track. They belong to all the trade associations and products conform to the industry standards. Many of the names that would be familiar to you are no longer around.
Metal studs, unless you are specifying propriatary products, are a generic item and should be reviewed based on their compliance with the relevant standards.
Mark, how would you regard the use of ‘high-performance’ or ‘dimpled’ studs (50, 57, or 65 ksi steel) vs. conventional studs (33 ksi) when addressing more than just partition heights?
If manufacturers show sectional properties that meet or exceed those of standard studs, does this satisfy other use conditions beyond limiting height? For example, for research laboratories and hospitals with higher floor-to-floor heights (15 or 16), wall-hung shelving, lab casework, lead shielding, and heavy equipment, will equivalent performance still be expected?
Another concern is that hospital design criteria typically is Seismic Design Category C even in site locations with low or moderate seismic activity. Is this affected by these substitutions?
Thanks.
My personal bias is that dimpled studs have limited applicability when dealing with engineered design which can often be the case in hospitals.
Ultimately these studs use lighter gage material that will make fastening harder with higher loads. In addition for the same depth of stud the dimpled studs will have a lower stiffness.
Thanks. I just needed to hear confirmation for my kneejerk reaction. If something sounds too good to be true, it usually is.
