Lifetime Material Warranty
Northstar not only recommends that maximum applied stresses (moments, shear, and impact) are below the
above stated allowable values, also maximum deflection should be evaluated to ensure they are acceptable for
your specific application.
The information provided above is believed to be accurate. No warranty of any kind is made as to the suitability
of Northstar Vinyl Sheet Piling for a particular application or the results obtained therefrom. Northstar
recommends that you consult with local professional (qualified engineer and/or contractor) as to the suitability
