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.)
