1:The hot dip galvanized steel pipe line refers to a welded pipeline with hot dip galvanized finishing on both outer and inner walls.
The item is commonly used to build steel structures or utilized to transfer gaseous or liquid substances.
Made in according to ASTMA53 and ASTMA120 standards, the hot dip galvanized welded steel pipeline can also be utilized to build supporting brackets for farming greenhouses.

Technical Specifications
Size Variety: 1/2″ ~ 12″ (21.3 ~ 323.8 mm).
Wall Thickness: 1.8 ~ 12mm.
Requirement: ASTM A53, ASTM A120.
Steel Grade: GR.B, Q195, Q235, Q345B.
End Complete: Plain end, thread end, with coupling.
Finish: Hot dip galvanized.

2:The pre-galvanized steel pipe refers to bonded tube which undergo degreasing, rust elimination, phosphorization, and drying procedures before galvanization. The treatments prior to galvanization enable the item to be conveniently plated with a zinc finish, and also ensure consistent finishing thickness, strong finish adhesion, and enhanced deterioration resistance. The per-galvanized bonded tubes are widely utilized in heat, water, and gas supply systems, farming greenhouse building and construction, steel structure construction, in addition to medium and low pressure piping system.

Wall Thickness: 0.4 ~ 6mm.
Standard: ASTM A53, ASTM A120.
Steel Grade: GR.B, Q195, Q235, Q345B.
End Complete: Plain end, threaded end, with coupling.
Pipeline Finishing: Pre-galvanized.
