Galvanized Steel Pipe in Round Square and Rectangular Sections
Zinc coated pipe in welded and seamless routes for outdoor structures water lines and frames that cannot be repainted
Galvanized steel pipe is the zinc coated part of the steel tube range and holds both the welded and the seamless routes in round square and rectangular section. The welded items cover Galvanized Welded Round Steel Pipe, Galvanized Welded Square Steel Pipe and Galvanized Welded Rectangle Steel Pipe against standards including ASTM A53, EN10217, DIN 2458, IS 3589, JIS G3452 and BS1387. The seamless items cover Galvanized Seamless Steel Pipe, Galvanized Seamless Square Steel Pipe and Galvanized Seamless Rectangle Steel Pipe in A53 Gr. A and Gr. B, A106 Gr. A and Gr. B, A333 Gr1 Gr3 Gr6 and S355JR S355JO and S355J2, supplied to schedule wall from SCH5S up to SCH160 and XS. Buyers use this part of the range when the structure sits outdoors and a painted section would mean a maintenance cycle nobody has budgeted for.

What This Range Is For
Painted Sections Corroding in Outdoor Frames
A painted tube frame in a greenhouse a fence line or a solar mounting rail starts rusting at every cut and weld. A galvanized surface carries the protection from the day the pipe is unloaded.
Standards That Differ Between Buyer and Mill
One project quotes ASTM A53 while the local inspector works to EN10217 DIN 2458 IS 3589 JIS G3452 or BS1387. The welded pipe here is made against that list so the order can be placed in the standard your documents use.
Seamless Needed Where Welded Is Not Accepted
Pressure and low temperature duties often rule out a welded seam. Galvanized seamless pipe in A106 and A333 grades covers those lines in the same enquiry as the structural sections.
Section Shape Split Across Suppliers
Round pipe for services and square or rectangular hollow section for the frame usually come from two sources. All three shapes sit in this range in both welded and seamless routes.
Random Lengths That Waste Material on Site
Length is supplied in a range so lengths can be set to the bay or the span instead of being cut down from a fixed mill length and scrapped.
Who Buys It
Buyers Who Order From This Range
- Greenhouse and agricultural structure builders framing in square and rectangular galvanized section
- Solar mounting and racking fabricators specifying zinc coated tube for outdoor service
- Water and fire line contractors buying galvanized round pipe against ASTM A53 or BS1387
- Scaffolding fence and handrail manufacturers needing coated tube that does not get painted on site
- Mechanical contractors ordering seamless galvanized pipe in A106 or A333 grades
- Pipe stockists and distributors carrying a range of diameters and wall schedules
Core Advantages
Why Source This Range From Tianyu Metal
Welded and Seamless Under One Category
The same enquiry can carry welded structural sections and seamless line pipe so a mixed bill of materials does not need a second supplier.
Six Standards Covered on the Welded Line
Welded pipe is made to ASTM A53 EN10217 DIN 2458 IS 3589 JIS G3452 and BS1387 so the pipe matches the standard your specification names.
Wide Diameter and Wall Range
Welded pipe runs from 21.3mm to 660.4mm outside diameter which is 1/2 inch to 26 inch with wall thickness from 1.5mm to 22.2mm.
Schedule Wall on the Seamless Route
Seamless pipe is supplied in SCH5S SCH10S SCH20S SCH20 SCH30 STD SCH40 SCH60 SCH80 SCH100 SCH140 SCH160 and XS so the wall can be quoted the way a piping drawing states it.
Grades From Several Naming Systems
Material covers ASTM A53 Gr A and Gr B EN S275 S275JR S355JRH and S355J2H and GB Q195 Q215 Q235 Q345 and the L175 to L555 line pipe grades.
Length Set to the Job
Length is supplied from 0.3 to 18 metres so the pipe can be cut to the bay spacing rather than to a single fixed mill length.
Application Scenarios
Where This Range Ends Up
Greenhouse and Shade Structure Frames
Square and rectangular galvanized section forming arches purlins and posts that stand in wet soil and are never repainted.
Solar Mounting and Ground Racking
Galvanized tube legs and rails for ground mount arrays where the structure has to last outdoors without maintenance access.
Water Supply and Fire Protection Lines
Galvanized round pipe in ASTM A53 or BS1387 for building services where the internal surface is also coated.
Fencing Handrail and Barrier Work
Posts rails and infill in galvanized round and square section for roadside and site boundary work.
Structural Hollow Section for Sheds and Canopies
Welded square and rectangular pipe in Q235 Q345 S275JR or S355J2H used as columns and rafters in light industrial buildings.
Mechanical and Low Temperature Piping
Galvanized seamless pipe in A106 Gr. B or A333 Gr6 for mechanical services and cold service lines where a seam is not accepted.
Buying Guide
What To State When You Order
State the section shape first whether round square or rectangular and then give outside diameter or the two face dimensions
Give wall thickness either in millimetres from 1.5 to 22.2 or as a schedule such as SCH40 or SCH80 and say which system your drawing uses
Name the standard the order is placed against such as ASTM A53 EN10217 DIN 2458 IS 3589 JIS G3452 or BS1387
Give the grade from the naming system you work in such as A53 Gr B S355J2H Q345 or A333 Gr6
State the length you want within 0.3 to 18 metres and whether ends are plain cut beveled or threaded
Say whether the pipe is welded or seamless and confirm the packing and the mill test certificate before loading

Galvanized Steel Pipe FAQ
What diameters and wall thicknesses are available in welded galvanized pipe?
Outside diameter runs from 21.3mm to 660.4mm which is 1/2 inch to 26 inch and wall thickness from 1.5mm to 22.2mm. Length is supplied from 0.3 to 18 metres.
Which standards do you make galvanized welded pipe to?
The welded pipe standards listed are ASTM A53 EN10217 DIN 2458 IS 3589 JIS G3452 and BS1387. Tell us which one your specification names so the pipe is ordered against it.
What is the difference between the seamless and welded items here?
Seamless galvanized pipe is a long pipe of steel with a hollow section and no joint around it and then the surface is galvanized. Welded pipe is formed and seam welded before coating and is normally the more economical choice for structural work.
Which grades can I specify?
Welded pipe covers ASTM A53 Gr A and Gr B EN S275 S275JR S355JRH and S355J2H and GB Q195 Q215 Q235 Q345 together with L175 L210 L245 L320 and L360 to L555. Seamless covers A53 Gr. A and Gr. B A106 Gr. A and Gr. B A333 Gr1 Gr3 Gr6 and S355JR S355JO and S355J2.
Can I order wall thickness as a schedule rather than in millimetres?
Yes. The seamless range is quoted in SCH5S SCH10S SCH20S SCH20 SCH30 STD SCH40 SCH60 SCH80 SCH100 SCH140 SCH160 and XS so a piping drawing can be quoted without conversion.
Do you supply square and rectangular pipe galvanized as well as round?
Yes. Galvanized square and rectangular pipe are supplied in both the welded and the seamless routes alongside round pipe so a frame and its service lines can come on one order.
