SCH 80 hot-dip galvanized steel pipe is an American-standard heavy-wall, high-strength pipe with excellent mechanical strength, pressure rating, and impact resistance. It is widely applied in outdoor projects, building structures, fence support and other scenarios. It can normally serve 15 to 25 years in regular outdoor environments, and maintain stable performance for 8 to 12 years in humid and coastal areas. Wanzhi can customize and manufacture galvanized pipe products in various specifications, including galvanized round pipes, square pipes, rectangular pipes and galvanized pipe fittings.
Standard: ASTM A53, ASTM F1083, ASME B36.10
Zinc Coating: 30 – 275g/m2
MQQ: 10 tons
What Is Schedule 80 Galvanized Pipe?
Schedule 80 Galvanized Pipe refers to hot-dip galvanized steel pipe complying with the ASME B36.10 standard. Made of low-carbon steel substrate, the pipe is processed by high-frequency welding and overall hot-dip galvanizing, with the galvanized coating thickness reaching Z275/G90. 80 denotes the fixed wall thickness grade of the pipe, rather than the pipe diameter.
Under the same nominal size, Schedule 80 pipe has a thicker wall than Schedule 40 pipe, featuring higher pressure bearing capacity and structural strength. It is widely used in industrial facilities, construction projects, commercial supporting facilities and other scenarios that require high pipe strength and corrosion resistance.

WanZhi SCH 80 Galvanized Pipe Prices
The price of Schedule 80 galvanized steel pipes is mainly affected by raw material costs, galvanizing processes, wall thickness, customized specifications and other factors, with a price range of USD 600 to 1,000 per ton. Due to its thicker wall thickness, Schedule 80 pipes are approximately 20%-30% higher in price than schedule 40 pipes.
In addition to Schedule 80 galvanized pipes, Wanzhi Group also supplies a full range of steel pipe products, including galvanized round pipes / square pipes, seamless steel pipes, spiral welded pipes, galvanized angle steel / channel steel, as well as custom-specification products.

SCH 80 vs SCH 40 Galvanized Pipe Comparison
Choose SCH 80 for strength and pressure. Choose SCH 40 for general-purpose, cost-effective utility piping.
- Wall Thickness: For the same nominal size, SCH 80 has a much thicker wall than SCH 40, belonging to extra strong thick-wall pipes.
- Pressure & Strength: SCH 80 offers better pressure resistance, impact resistance and load-bearing capacity; SCH 40 is standard wall thickness with medium pressure-bearing performance.
- Applications: SCH 80 is suitable for outdoor heavy-duty structures, fence posts, high-pressure fluids and coastal anti-corrosion projects; SCH 40 is for ordinary building water supply and drainage, light supports and general municipal civil projects.
- Weight & Cost: SCH 80 is heavier per unit, consumes more raw materials, and its price is higher than SCH 40; SCH 40 is cost-effective with less material, suitable for regular projects.
- Service Life: With the same zinc coating, SCH 80 has a longer overall service life and better anti-corrosion and anti-perforation ability due to its thicker wall margin.
