Galvanized steel pipe 21.3-406mm in a welded round-pipe range with 1.5–12 mm wall directions and a 6 m reference length. Grade options include S275JR, St37, 16Mn, A53, Q195, A36 and S355JR. Confirm the final grade, standard, coating and length per order.
This welded galvanized round steel pipe range covers outside diameters of 21.3–406 mm, wall thicknesses of 1.5–12 mm and a reference 6 m length. Grade options include S275JR, St37, 16Mn, A53, Q195, A36 and S355JR. Confirm the exact grade, standard, diameter, thickness, length and zinc coating per order.
The range is designed for buyers who need larger welded galvanized pipe for construction, fabrication, frames or utility assemblies. The 21.3–406 mm diameter direction and 1.5–12 mm thickness direction must be narrowed to the project drawing before production. A 6 m reference length does not replace the required cutting tolerance or delivery length. The buyer should also identify the connection method, lifting plan and exposed environment for larger bundles. This information keeps handling and receiving requirements visible before shipment.
Grade names in the list serve different specification systems. A53, A36, 16Mn, St37, S275JR and S355JR should not be treated as interchangeable. The quotation should identify one governing grade and standard, together with the required inspection documents. Keep the selected grade consistent across the drawing and purchase order.

This range can be reviewed for construction and fabrication projects where a welded galvanized round pipe is specified. The larger diameter direction helps buyers compare structural or utility assemblies, but the final selection still depends on the project drawing, handling plan and connection details. Buyers can separate diameter, wall thickness and length decisions before requesting a final quotation.
Confirm cutting, beveling, threading, grooving, drilling and end preparation against the drawing. Large diameters may require specific lifting, stacking and handling arrangements. Confirm the receiving equipment and connection method before production approval. State the required bevel, plain end or threaded detail before cutting. Record the approved end treatment and cutting tolerance with the order. Confirm whether the pipe will be joined on site.
Confirm bundle weight, pipe length, end protection, strapping, moisture protection, markings and loading method per order. Keep the galvanized surface protected from impact, abrasion and prolonged wet storage. Confirm how the bundles will be lifted and unloaded at destination. Identify each bundle by size, grade and length.
No. This range is welded galvanized round steel pipe. Confirm weld and inspection requirements per order.
No fixed conclusion should be made from the reference length. State the required length and tolerance for confirmation.
