Frequently Asked Questions

What voltage levels do these steel structures support?
Our structures are designed for a wide range of substation requirements, including 10KV, 33KV, 66KV, 110KV, 220KV, 500KV, and other customized voltage levels.
What are the primary materials and strength grades used?
We use high-strength steel such as Q355B (A572) with a minimum yield strength of 355MPA and Q235B (A36) for various structural components.
How is the steel protected against environmental corrosion?
All steel components undergo a hot-dip galvanizing process according to GB/T13912, EN ISO146, or ASTM/A123 standards to ensure a lifespan of over 50 years.
Do you provide on-site installation support?
Yes, we support installation and can arrange for professional engineers to provide technical guidance on-site to ensure the structural integrity of the project.
What is the typical lead time for a project?
For orders up to 1000 tons, the standard lead time is approximately 30 days. Projects exceeding 1000 tons are subject to negotiation based on complexity.
Which design standards do your products follow?
