The chosen answer indicates flat steel as the material suitable for anchor strap securing techniques for steel tanks, which is correct because flat steel exhibits excellent strength, durability, and resistance to corrosion when properly treated. In the context of installing underground storage tanks, especially those made of steel, it is crucial to use materials that can withstand significant loads and prevent movement or upheaval due to soil pressure, hydrostatic pressure, or seismic activity.
Flat steel provides the necessary tensile strength to secure the tank effectively, ensuring it remains anchored in place despite external forces. The use of flat steel also allows for reliable connections to the tank and other anchoring components, creating a stable, secure installation.
In contrast, other materials such as fiberglass may not offer the same level of strength or impact resistance, plastic may be too flexible and susceptible to breakage or deformation under stress, and wood could deteriorate over time when exposed to moisture and soil conditions, compromising the integrity of the installation. Thus, flat steel’s robust properties make it the preferred choice for anchoring steel tanks.
