The standard way that MSS goes both wider and higher with structure profiles is to add to the length of the steel tubing which is used. We have a total of 8 various lengths in our inventory starting with 1”x2”x11’. As the structures get taller and wider the wind and snow loads increase exponentially. This means that we will switch to larger steel and/or reduce the hoop spacing.
The largest structure we do with engineered drawings is 30’ wide which is fabricated with 1”x3”x23’ galvanized tubing. We do occasionally bring in 1”x3”x27’ tubing to make a tall 30’ wide or up to 36’ wide. In the case of what we are using as our work area, we have mounted this structure on the 2’x2’x4’ concrete blocks which weigh approximately one ton each.
Going 2’ higher allowed us also to go a little wider so that we could capture both of the overhead doors to the shop. This structure is 38’ wide and approximately 19’ at the peak. This configuration made it necessary to build the structure with 2’ hoop spacing, 3 rows of purlins (lateral spacers), cross ties and diagonal bracing.
Normally covering this size of structure with plastic is not a practical option since 56’ wide cover is required and the maximum width available is 48’. In this particular application, since the structure is only 30’ long we could use a 32’x60’ sheet installed sideways.
The end will be fabricated in a way that is both functional and to displays some of the options which our customers may want to use. We also took special care to use scaffolding for putting up such a large structure. Please call to have us help you customize your shelter solution!
