Galvanized Steel Pipe Astm A36
Hot dipped galvanized square steel pipe Astm A36 is processed by processes such as hot dip plating or electro-galvanizing, which can effectively prevent surface corrosion of steel pipes and extend their service life.
Hot dipped galvanized round steel pipe also has excellent weather resistance and can be used in different climate conditions, so they are widely used in outdoor construction and equipment manufacturing.
Dimensional specifications
The dimensional specifications of steel pipe A36 is usually described by the outer diameter (OD), wall thickness (WT) and length (L).
1. outside diameter (OD): OD is the distance from the outer surface of the pipe to the centre, usually in inches (inch) or millimetres (mm) for the unit. Common OD includes 1/2 inch, 3/4 inch, 1 inch, 1-1/4 inch, etc.. Different outside diameters for different applications, such as home plumbing or industrial piping.
2. wall thickness (WT): wall thickness is the thickness of the pipe wall, usually in inches or millimetres. Wall thickness directly affects the strength and durability of the pipe. Thicker wall thicknesses are often used in applications that require greater load-bearing capacity.
3. length (L): length indicates the overall length of the pipe, usually in feet (foot) or metres (meter). Common lengths include 10 ft, 20 ft, 6 metres, and so on. Pipe length specifications can be customised to meet the needs of a specific project.
Advantages
Durable
Galvanized steel pipe corrosion-resistant life can be extended several times or even dozens of times, and it can easily cope with moisture, rain, soil and some industrial atmospheric environments, significantly reducing maintenance costs and replacement frequency, and lowering the cost of the entire life cycle.
Scientific protection
Using advanced hot-dip galvanizing process. This layer of "armor" provides excellent sacrificial anode protection - even if the surface is scratched, the zinc layer will still corrode first, protecting the internal steel from rust.
Strength and toughness
A36 hot dip galvanized steel pipe is known for its excellent weldability, formability and machinability, while providing a reliable balance of strength and toughness to meet a wide range of structural and load-bearing needs.
Reduce costs
Strong corrosion resistance means that almost no additional anti-corrosion maintenance is required during the life cycle of the pipeline, saving a lot of manpower and financial resources.
Extend life
Under standard atmospheric conditions, the protection life of high-quality hot-dip galvanized layers can reach more than 50 years, significantly improving the return on investment.
Reduce losses
Avoid unexpected shutdowns and replacements caused by pipeline corrosion damage, ensuring continuous and stable operation of the project.
Applications
Building structure field
Building scaffolding system (high strength, good weather resistance)
Plant steel structure pillars, roof trusses, purlins

Temporary buildings, modular house structures
Machinery manufacturing and industrial applications
Equipment frames, brackets, bases
Material conveying system structural parts
Simple platforms, workbench frames
Storage shelves (specific load-bearing requirements)
How to ensure quality?
Strict material selection: Only high-quality low-carbon steel coils or seamless steel pipes that meet the ASTM A36 standard are used as the base material.
Advanced technology: The fully automatically controlled hot-dip galvanizing production line is used to ensure that the zinc liquid temperature and galvanizing time are precisely controlled, and the zinc layer adheres firmly and evenly.
Precise control: Strictly implement ASTM A123/A123M (for structural parts galvanizing) or ASTM A153/A153M (for hardware galvanizing) standards, and strictly test the zinc layer thickness/weight (common methods: magnetic thickness gauge, weighing method) to ensure that it meets or exceeds the standard requirements (such as: average zinc layer weight ≥ 610 g/m²).
Comprehensive quality inspection: From the storage of raw materials to the delivery of finished products, a multi-channel quality inspection process is implemented, including dimensional tolerance, surface quality (no missing plating, no dripping, no peeling), mechanical properties (yield strength, tensile strength, elongation) and zinc layer adhesion test (such as hammer test, bending test).
Authoritative certification: Products can provide test reports that comply with ISO quality management system certification to ensure quality traceability.
