What is the standard delivery state for S275NLH?

Only normalized (+N) delivery condition, which ensures stable low-temperature toughness performance.

Does S275NLH have good welding property?

It is designed as weldable structural steel with low carbon equivalent, perfect for building welded connections.

What is the biggest advantage of S275NLH compared with S275NH?

S275NLH passes impact test at -50teamperature, while S275NH only meets -20teamperature requirement, more suitable for extremely cold regions.

What is your minimum order quantity?

MOQ is flexible, we accept small sample trial orders and bulk ton-level construction project orders.

How do you pack tubes for export sea transportation?

Coated with anti-rust inside and outside, sealed with plastic end caps, bundled by high-strength steel strips; small tubes packed in plywood cases.
