Notes:
Carbon (C): Increases strength and hardness but reduces weldability
Manganese (Mn): Improves strength, toughness, and wear resistance
Phosphorus (P) & Sulfur (S): Kept low to maintain ductility and weldability
Silicon (Si): Used for deoxidation and improving strength
1.Building structures and systems: Application in building frame, column, and the system of support. Long duration stability for the High strength and the good corroison resistance of structure.
2.Water Supply and Sewerage Systems: For water conveyance in city and industrial pipelines. The zinc coating protects the rust and extends the life-span.
3.Scaffolding systems: It can be seen everywhere from temporary construction scaffolds. Carrying great loads, it is ideal for working at height.
4.Fencing & Outdoor Structures: It also works well for fence panels, handrails and greenhouse frames. Good outdoor performance, can be weathered and corrosion-proof.
Thickness of zinc coating is from 30g/m² to 550g/m2 and we have multi surface treatment ways, such as hot-dip galvanized steel pipe, electro-galvanized steel pipe, pre-galvanized steel pipe etc.
Custom zinc coating can be produced according to customer requirements or specifications of contract based upon inspection reports submitted. Our manufacturing process allows us to maintain a tight thickness tolerance of ± 0.01 mm.
We use laser precision cutting technology to guarantee clean, smooth pipe ends without burrs. The product can be straight seam welded galvanized steel pipe, seamless one.
The standard length for cuts is 6–12 meters, in 20ft and 40ft US standard lengths. Special lengths for example 13 m or others can be also produced on demand.
We tend to our global clients with fast delivery, stable supply and competitive price with over 5000 tons production capacity per day.
Q1：What Is Hot Dip Galvanized Steel Pipe?
A: Hot-dip galvanizing is a form of galvanizing involving coating of a steel pipe with a layer of zinc to protect and enhance the steel pipe's life.
Q2: What is the biggest benefit of galvanizing?
A: The zinc layer can form excellent anti-rust protection, especially in outdoor and moist condition.
Q3: What kinds of steel pipe can be galvanized?
A: Seamless and welded steel pipe both can be hot dip galvanized.
Q4: What are the popular uses/application?
A: building, scaffolding, water pipe line, fencing and industrial structural.
Q5: Can I customize it?
A: Yes, you can customize the size, thickness, length and gama coat.
Q6: What inspection documents will you provide?
A: Mill Test Certificate (MTC), packing list, invoice, and third party inspection, if required.
