Choose one pile profile and grade before applying the title’s JIS and strength requirements.
Grade and standard scope
SY290 and SY390 appear with SY295, Q235, Q345, S275 and S355 references. Confirm one actual grade and applicable JIS A5528 requirements rather than assume equivalent properties across standards.
Profile dimensions
The single option is 400×100×10.5 mm while the width description gives 450–750 mm. Clarify the actual U or Z section and obtain a dimensioned interlock drawing.

Structural evidence
No measured yield or installed capacity is supplied. Request the selected profile’s dimensional and mechanical documentation and define welding or cutting scope; high strength wording alone does not establish project acceptance or a rated foundation system.
