Frequently Asked Questions

Learn more about steel plate for storage tanks applications.
The most common steel plate grades for aboveground storage tanks are ASTM A36 and ASTM A516 Grade 70 grades, depending on design temperature, thickness requirements and stored product. When selecting plate, manufacturers should consider:
  • Design temperature
  • Tank diameter and height
  • Weldability requirements
  • Corrosion allowance
  • Material availability
  • Project lead time
For many petroleum and chemical storage applications, A36 and A516 Grade 70 remain among the most commonly specified materials due to their availability, material properties and machineability.
Storage tank fabricators typically require material test reports (MTRs), heat traceability records, grade certifications and quality documentation for steel plate used in tank construction. Documentation commonly includes:
  • Mill test reports (MTRs)
  • Heat numbers
  • Mechanical properties
  • Chemical composition
  • Plate dimensions and thickness certifications
  • Inspection records
  • Traceability documentation
Since Leeco stocks prime plate, these documents can be provided for every order.
It can. Depending on the project, pressure vessel plate may require supplemental testing such as ultrasonic testing, impact testing, HIC testing or other customer-specific requirements. Certification requirements vary by application, industry code and end-user specifications, so requirements should always be confirmed during procurement.
Whether a tank manufacturer should purchase processed steel plate depends on labor availability, equipment utilization, production volume and delivery requirements. Purchasing cut-to-size and beveled plate can reduce handling, programming, scrap generation and bottlenecks while allowing fabrication teams to focus on rolling and welding. Manufacturers with excess processing capacity may benefit from in-house processing, while labor-constrained shops often prioritize production-ready material.
