Quick Answers
SS400 Tee – Overview
SS400 is Japan's most common structural steel, broadly equivalent to ASTM A36 and S235JR. It is the dominant mild steel grade in Asian markets for beams, plates, pipes and fabrications, with wide availability from Japanese and Korean mills.
BB Infras sources SS400 Tee from approved European, Japanese and domestic mills for heavy engineering fabricators, shipbuilders and infrastructure contractors, with full EN/ASTM mill certification and dimensional compliance reports. All SS400 Tee are manufactured to ASME B16.9 / MSS SP-75 with 100% dimensional inspection. Sizes range from ½” NB to 48” NB with wall thicknesses from SCH 10 through XXS.

Storage & Handling Guidelines
- Store on wooden dunnage or pipe racks — never directly on concrete to avoid moisture-induced corrosion.
- Stack with appropriate separators; observe safe stack heights to prevent deformation.
- Apply plastic end caps or plugs to all open ends to prevent ingress of moisture, dust and insects.
- Keep material dry and ventilated; store under cover in humid or coastal climates.
- Use nylon slings or padded lifting hooks — never bare wire rope directly on surface.
- For long-term storage (>6 months), re-apply protective oil coating or wrap with VCI (Vapour Corrosion Inhibitor) film.
- Identify items with heat number tags throughout storage for full MTC traceability.
