Overview

Structural Steel Pipe covers round, square, or rectangular hollow structural sections used for columns, frames, trusses, and general fabrication on export construction packages. Procurement should lock section shape and size (OD or HSS dimensions), wall thickness, grade and standard (for example ASTM A500 / EN 10219 class or project carbon structural practice), length, end finish, and EN 10204 3.1 documentation. Structural hollow sections are not automatic pressure pipe—do not treat them as A106/A53 process line substitutes without a code review. Confirm packing, bundle marks, destination port, and any galvanizing or paint system after fabrication if the PO scopes surface protection.

FAQ

What should I confirm before ordering structural steel pipe?

Confirm standard and grade, size, wall thickness, length, ends, coating, quantity, destination port, packing method, and whether EN 10204 3.1 MTC or third-party inspection is required.

Is structural steel pipe the same as API line pipe?

Not usually. Structural pipe is specified for frames and fabrication under structural standards, while API 5L line pipe is for pipeline service with different grade and testing scopes. Share end use and design code for the practical product family.

What export documents can ship with structural pipe?

We can coordinate mill test certificates (typically EN 10204 3.1), packing lists, commercial invoice support, lot identification, loading photos, and optional SGS, BV, or Intertek inspection before shipment.
