Load Span Tables

3. Special Engineered Systems
Tables 1 & 2 herein are based on standard APA and commercial standards PS-1 criteria. However certain Olympic Panel customers and engineered concrete form system manufacturers may publish different span tables based on their own system tests, field conditions and experience.
