ASTM A527 G90 Galvanized Duct ...

ASTM A527 G90 Galvanized Duct Pipe is a type of air conduit made from galvanized steel, a material coated in zinc to prevent corrosion and rust. These ASTM galvanized pipes are used in heating, ventilation, and air conditioning systems due to their durability, moisture resistance, and fire-resistant properties. They are common in various applications, including commercial and industrial settings, outdoor uses, and locations with dust extraction needs.


Material: The standard material is galvanized mild steel, with a zinc coating to prevent corrosion. For example, Nordfab galvanized ducting uses ASTM A527 with a G90 rating.


Gauge: This refers to the thickness of the metal. Common gauges range from 22ga to 10ga, with lower numbers indicating thicker metal. The appropriate gauge for your application depends on the required strength and pressure rating.


Sizes: Available diameters for round ducting range from 3 inches to 84 inches, with lengths often sold in 3, 5, or 10-foot sections. Rectangular and oval ducts are also manufactured in a range of sizes.


Connections: Common connection types include snap-lock for easy assembly, rolled lip for quick-fit clips, and flange-to-flange for larger systems.

ASTM A123 Hot Dip Galvanized S...

ASTM A123 is the Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products.


This specification directly applies to the manufacturing of hot dip galvanised pipe, establishing comprehensive requirements for the galvanizing process , including minimum coating thickness, coating weight, finish quality, and adherence to the base steel.


This specification is widely applied to steel shapes, plates, bars, and assembled fabrications intended for corrosion resistance through hot-dip galvanizing.


(For hot dip galvanised pipe specifically, these requirements ensure superior corrosion resistance through the hot-dip galvanizing process. The rigorous standards guarantee that every hot dip galvanised steel pipe delivers consistent performance and long-term durability in demanding applications.)

#FAQs about Our Galvanized Steel Pipes
  • What is the difference between hot-dip galvanized and pre-galvanized pipe?
  • Hot-dip galvanized (HDG) pipe is submerged in molten zinc after full-size fabrication, forming a thick, uniform coating (≥45 µm) that offers 20–30 years of corrosion protection even in outdoor exposure. Pre-galvanized (or mill-galvanized) strip is zinc-coated before roll-forming/welding; the coating is thinner (8–15 µm) and economical for dry, low-corrosion environments.
  • What international standards do your galvanized pipes meet?
  • Our pipes are produced and tested to ASTM A53 Grade A/B, ASTM A123 (zinc coating), EN ISO 1461 (HDG), BS 1387, GB/T 3091, and can be supplied with UL/FM, CE, ISO 9001 & 14001 certifications.
  • Can galvanized steel pipe be welded?
  • Yes—HDG pipe can be welded by grinding off zinc 25–50 mm back from the joint, then re-spraying zinc-rich epoxy after welding to restore corrosion protection. Use AWS E6010/E7018 low-hydrogen electrodes and ensure adequate ventilation to manage zinc fumes.
  • What diameter and wall-thickness ranges do you stock?
  • NPS 1/8"–44" (OD 10.3–1 219 mm) with wall SCH 10–XXS (1.2–25.4 mm); lengths 5.8 m, 6 m, 11.8 m, 12 m or cut-to-length.
  • What is the typical lead time for a full-truck order?
  • Standard sizes ex-stock within 3–5 days; non-stock sizes or added coatings 10–15 days. Container shipments can be ready for vessel loading within one week.
  • Do you provide MTC and traceability?
  • Yes—each pipe is marked with heat number, size, standard, and production date; MTC EN 10204/3.1 is issued, including chemical composition, mechanical properties, zinc-coating weight, and test results.
