Solar mounting structures for every terrain. Transmission towers from 35kV to 1000kV. Communication towers, substation steelwork, oil & gas structures. Industrial steel coils, profiles, and special grades.

Most structural steel suppliers cover one category. Winture covers the full energy infrastructure stack — and all of it runs through the same ISO 9001-certified quality management system, the same in-house laboratory, and the same documentation chain.

What this means for you:

One supplier, one audit, one point of accountability across multiple product lines and multiple projects.

Every Winture product delivery includes a complete, traceable documentation chain:

This is not produced on request. It is the standard output of our production system. Your project engineers, lenders, and certification bodies receive what they need without a chasing process.

Winture's ISO-certified laboratory is not a third-party service. It is our facility, our technicians, our equipment — running continuously on our production output.

When we state that a product meets ISO 1461 coating thickness or ASTM A572 Gr.50 mechanical properties — we have the test data, generated on that batch, to prove it.

90% of our fabrication processes are CNC-controlled, ensuring ±0.5mm dimensional tolerance on hole position and section geometry across every batch. For solar structures, this means bolt-only site assembly without field adjustment. For transmission towers, it means we pre-assemble critical sections in our factory yard before galvanizing — verifying every connection node fit-up before the structure leaves our facility.

Zero-rework on site is not a marketing claim. It is the result of a production process where dimensional problems are found and fixed before, not after, delivery.

30,000 MT monthly capacity is our standard operating output — not a peak figure. Tier 1 mill partnerships with ≤72-hour coil delivery to our production floor. Manufacturing facility within 50km of Tianjin Port.

For large project orders, we provide a production schedule with weekly milestone visibility. For every shipment, a named logistics contact manages documentation, container coordination, and customs clearance from production completion through to delivery confirmation.
