Galvanized steel pipe DN15-200 in a welded construction range with 1.0–6.0 mm wall directions and Q195, Q235B, Q345B, SS400, S275JR and S355JR grade options. Confirm the selected grade, standard, zinc coating, length and documents per order.
This welded galvanized steel pipe range covers DN15–200 construction and general fabrication requirements, with a stated thickness direction of 1.0–6.0 mm. The listed grade options include Q345B, Q195, SS400, St52, Q235B, S355JR, St37 and S275JR. Confirm the selected grade, standard, zinc coating, outside diameter, wall thickness and end condition per order.
The range is intended for buyers who need welded galvanized pipe rather than seamless tube. Zinc coating provides the specified galvanized surface, while the steel grade and wall thickness determine whether the pipe fits the project drawing. CE and RoHS requirements, when applicable to the order, must be confirmed against the final specification and documentation. The buyer should also identify the exposed environment, connection method and required finish before selecting a pipe size.
The broad grade list should not be treated as one fixed chemistry or one universal performance level. Q195, Q235B, Q345B, SS400, S275JR and S355JR are separate material choices. State the required grade before quotation so production and inspection use the same basis. This keeps the order clear when several sizes share one project.

This range can be reviewed for construction frames and general fabrication where the drawing permits welded galvanized pipe. The DN range also gives buyers a practical starting point for comparing pipe sizes before the final grade and wall thickness are selected. It also supports clearer quotation comparisons across multiple project sections.
Confirm cutting, threading, grooving, drilling, welding and end preparation before production. The receiving line should provide the drawing, tolerances and connection method. Do not select a grade only from the application name; match the pipe to the project calculation and forming route. Confirm whether the buyer needs plain ends, threaded ends or another connection detail. Record the final end treatment on the purchase order.
Confirm bundle size, pipe length, end protection, strapping, moisture protection, marking and loading requirements per order. Packaging must protect the galvanized surface during handling and transport. State whether mixed sizes may share one bundle and how the bundles will be unloaded.
No. This range covers welded galvanized steel pipe. Confirm the weld and inspection requirements per order.
Yes, subject to the available production range and order confirmation. State the required thickness and tolerance.
Choose the grade named in the project drawing or calculation. The listed grades are alternatives, not one combined grade.
No. Confirm the applicable documentation and compliance scope for the specific order.
Cut-to-length supply can be reviewed when the required length and tolerance are stated per order.
