For effective tank installation, which of the following should NOT be overlooked?

Proper material selection is critical for effective tank installation because the materials used can significantly impact the durability, safety, and compatibility of the tank with the substances it will contain. Choosing the right materials ensures that they can withstand the expected environmental conditions, chemical interactions, and mechanical stresses over time. This decision directly influences the overall integrity of the tank and can prevent costly repairs or hazardous leaks in the future.

Special decorative coatings, while they can enhance the aesthetic appeal of a tank, do not affect its primary functional capacity and safety features. Similarly, unit positioning is important for operational efficiency and maintenance access, but it is contingent on having the right materials in the first place. The timeliness of project completion is vital for project management and budgeting but is secondary to ensuring that the fundamental aspects of the installation, like material suitability, are adequately addressed.
