What is JIS I Beam?
JIS I Beam is a hot-rolled structural steel beam manufactured according to Japanese Industrial Standards. It is mainly used for load-bearing structures, frames, supports, and industrial fabrication.
What steel grades are available for JIS I Beam?
Common grades include SS400, SS540 and SM490. Other equivalent grades can be supplied according to project requirements.
Can SKSteel supply JIS I Beam with inspection documents?
Yes. SKSteel can provide Mill Test Certificates, chemical composition, mechanical properties, and third-party inspection services according to customer requirements.
What is the difference between JIS I Beam and European I Beam?
JIS I Beams follow Japanese dimensional standards, while European IPE/IPN beams follow European standards. Selection depends on project drawings and engineering specifications.
Can 6meter or 12meter JIS I Beam be shipped by container?
Yes, SKSteel can arrange container shipment according to beam length, bundle size, destination, and loading plan.
