Made of Douglas Fir, these are used as floating platforms for construction purposes, primarily for marine construction activity. What differentiates float stages from other types of mats or timber platforms is the wood that is used. Douglas Fir is used because of its buoyancy: this allows the mat to float while holding equipment, work crews, etc., as well as being easily accessible by water. This cost-effective and durable product provides stability to wet job sites, temporary access to roads, as well as a temporary work-site platform. It can also be used outside of the water to create a barrier between ships and their cargo as well as transport for heavy equipment.
