Be sure to study any scaffold plank product you're considering. Investigate and understand the design properties so you can make an informed decision. While it is good that you have numerous products to chose from, it is very important to know that some scaffold plank are priced low because the product has lower structural strength. If you select a wood scaffold plank with lower design properties, your planks are more susceptible to break as the boards age and they will not last as long. Note that all wood plank fatigue over time just from normal wear-n-tear and exposure to weather elements, so the "Extreme Fiber Bending" strength (Fb) is a very critical design property to observe.
