Products: nine families, one standard each
Start with the standard, then the grade. We organise our regular supply into nine families, each with grade, thickness and delivery-condition tables. From any family page you can take stock ex-warehouse or book forward from the mill.
Boiler & Pressure Vessel Plate
Q245R, Q345R, Q370R, 15CrMoR, 12Cr1MoVR and more to GB/T713 — the workhorse steels of drums, reactors and exchangers.
Low-Temperature Vessel Plate
16MnDR, 09MnNiDR, 08Ni3DR, 06Ni9DR to GB/T3531 — impact-tested down to -40°C through -165°C.
Wear-Resistant Plate
NM360 to NM600, WNM series and MN13 austenitic manganese steel to GB/T24186 — liners, buckets and chutes that last.
High-Strength Plate
Q460C, Q550D, Q690D and Wuyang WQ Q+T grades to GB/T16270 — the skeleton of cranes, pump booms and mining trucks.
Low-Alloy Structural Plate
Q345B/Q355B, Q390 and Q420 families to GB/T1591 — the most-used engineering steel of them all.
Bridge Structural Plate
Q345qC through Q420qE to GB/T714 — specified for box girders, trusses and sea-crossing spans.
Weathering Steel
Q235NH to Q550NH and Q450NQR1 to GB/T4171 — the patina is the paint.

常见问答
What if my grade is not listed?
The tables show our regular grades. Anything a Chinese mill currently produces can be forward-booked — Wuyang, Xianggang, Angang, Xingang, Nangang and more. Send grade, thickness, delivery condition and quantity and we will confirm the lead time.
Stock or mill booking?
Tight schedules suit stock; special grades and oversized plates suit booking. Typical booking cycles are three to five weeks for standard vessel plate, longer for special grades.
Are the thickness ranges fixed?
They are common supply ranges. Individual grades depend on mill capability — out-of-range enquiries are confirmed with the mill before production is scheduled.
