S420NL steel plate,S420NLH square hollow section,S420NL round bar

High-strength structural steel in S420NL grade, supplied in three primary product forms: hot-rolled plates, square hollow sections (S420NLH / SHS) and round bars. All products are manufactured to the EN 10025-3 specification and are offered alongside related EN 10025 grades (S275N, S275NL, S355N, S355NL, S420N, S460N, S460NL).

Key features

• Conforms to EN 10025-3 for weldable fine-grain structural steels with improved toughness.
• Available as hot-rolled plates, welded square hollow sections (SHS) and hot-rolled round bars to suit structural and fabrication needs.
• Commonly used for structural engineering, building frames, heavy fabrication, bridges and general construction components where higher strength and toughness are required.

Supply options

• Supplied in mill lengths, cut-to-length, or cut-to-size per buyer specifications (size ranges depend on mill and stock availability).
• Surface condition, dimensional tolerances and further machining/processing can be discussed to meet project requirements.

If you require detailed dimensional ranges, mechanical property data, or certification (mill test reports and inspection documents), please specify your required grade, dimensions and finished condition so a tailored quotation and lead time can be provided.
