In the metal building industry, you hear the term “steel line” used a lot, but the thing is—the term is not fully understood. So today, we want to clear up the murky space in which the steel line occasionally exists. Ready? Let’s do the steel line dance.
The Steel Line = the outside face of steel
It’s the outside face of the secondary member or wall girts. If there aren’t any secondary members, it refers to the outside face of the columns or eave strut.
Easy, right? Well…not always. As simplistic as the steel line seems, mixing your terminology, or not fully understanding the function of the steel line, can really affect the building process. For example:
- Anchor Rod placements for the foundation can be incorrectly placed if the steel line is not understood.
- When other construction, such as studs and brick, are incorporated into the building, the steel line is critical for locating the support member’s placement.
- When attaching to existing structures, the steel line may be required to overlap the endframe of the existing building. This is critical when determining the correct building length and in the case of combining multiple buildings.
The term is widely used not only here, but also across Canada, so you would think the correct use and comprehension of the term would be widespread, but it’s not.
