Grade Reference

Tell us your standard. We work from your specification.

We source to Chinese national standards and confirm the closest equivalent to your EN, ASTM, or JIS reference before production starts.

European (EN)American (ASTM)Japanese (JIS)Typical Application
S235A36SS400General structural fabrication, frames, brackets
S355A572 Gr.50SM490Higher-strength structural parts, load-bearing components
C451045S45CMechanical parts requiring higher hardness

Grade equivalents are for reference only. Final material specification confirmed before production. Not all grades are direct substitutes — differences in yield strength, chemistry, and testing standards may apply.

How We Handle Material

Chinese national standard material. Your specification confirmed.

01

You Share Your Reference

Tell us your grade — EN, ASTM, or JIS. We identify the closest Chinese equivalent and confirm any meaningful differences before the order starts.

02

We Confirm Before Production

Material selection is confirmed at quotation stage, not assumed. If your application has specific chemistry or testing requirements, we discuss this upfront.

03

Mill Certificate Available

Material certificates (mill test reports) available with orders. Confirms material grade, heat number, and mechanical properties.

Cutting Capability
