Safety
■
Use care when handling lumber to prevent injuries.
Always wear gloves and eye protection when
handling building materials.
■
Do not use lumber as ramps, planks, etc. Use only
as directed in this guide.
■
After sheathing, do not overload joists with
construction material in excess of design loads.
Storage and Handling
In Warehouse
■
Store bundles on a hard and level surface in a
covered shed and protect from weather. Avoid
contact with water or extended exposure to direct
sunlight.
■
Do not store lumber in direct contact with the
ground. All bundles come with corner protection
under the strap, and with 2x3 dunnage to keep
product off the ground when breaking bundles.
■
To avoid physical damage to lumber, use care
when handling bundles or individual components,
especially when handling with forklifts or cranes.
At Job Site
■
Keep lumber wrapped and covered during transit
from lumberyard to the job site.
■
Do not open bundles until ready to install.
■
To ensure that materials retain a low moisture
content after the bundle is broken, rewrap the
unused portion and make sure all four sides and
the top are covered.
■
Keep lumber off of the ground and covered at the
job site.
Use support blocks to keep
bundles out of mud and water
Protect lumber from sun and water
CAUTION: Wrap is slippery
when wet or icy
Align stickers directly over
support blocks
