framing every 2'. Or 4' with blocking spaced as noted for
purlin & girt spacing below.
Above typical roof layout.
Girts on walls spaced every 4 ft. See wind load info and chart.
Layout above will support
a 20 lb. load. For 25 lb. load position mid purlins every 3
ft. For 35 lb. load position all purlins every 2 ft.
In wind areas increase screw attachment pattern so wind does not pull
sheet off frame. Best to use our Screws with 3/4" sealing washers. Consult with us and bldg. dept if in hurricane zones.
Structural Loads are
stresses to structure from external or internal
forces.
Dead load are
gravity loads that are constant throughout structure's life.
These include equipment such as fans, heaters and plants suspended
from frame. Live loads are
temporary, such as snow loads and wind
loads. Snow loads determined by factors influencing snow & ice accumulation on
the structure. Snow loads vary
considerably by geographic location. Ask your local bldg. dept.
for snow load in your area. (
12 inches of light, fluffy snow or 2 to 4 inches of heavy, wet
snow = about 5 lbs per sq. ft.)
