Key Attributes
- Adaptability: Compatible with galvanized handrail pipe systems, HVAC ducts, and gas pipelines.
- Corrosion Resistance: Zinc coating prevents rust in humid, coastal, or chemical environments.
- Customization: Laser-cut threads, flanges, and bends tailored to project requirements.
- Eco-Friendly: Recyclable materials and low-VOC manufacturing.
Mechanical Properties
Tensile Strength
Our galvanized fittings achieve a tensile strength of 350–550 MPa, ensuring stability under high-pressure applications like galvanized gas pipe networks. This exceeds ASTM A53 requirements, making them ideal for industrial and municipal infrastructure.
Bend Strength
With a bend resistance 2.5× higher than standard pipes, these fittings maintain integrity in complex layouts, such as galvanized handrail pipe installations in multi-story buildings.
Identification & Marking
Each fitting is laser-etched with:
- Manufacturer’s logo and batch number for traceability.
- ASTM/BS/ISO compliance codes.
- Diameter, thickness, and pressure rating (e.g., galvanized 4 inch pipe marked “4”x6mm-PN16”).
Weight Calculation Formula
Use the formula for precise logistics planning:
Example: A galvanized 4 inch pipe (114 mm OD, 6 mm wall thickness) weighs:

Stainless Steel Rusting: Causes & Prevention
Despite its corrosion resistance, stainless steel may rust due to:
- Chloride Exposure: Coastal environments or de-icing salts degrade the passive oxide layer.
- Mechanical Damage: Scratches from improper handling expose underlying iron to oxidation.
- Galvanic Corrosion: Contact with carbon steel tools or fittings triggers electrochemical reactions.
Prevention: Use passivation treatments, avoid abrasive cleaners, and isolate stainless steel from dissimilar metals.
Applications
- Galvanized 4 inch pipe: Ideal for water supply, HVAC ducts, and structural supports.
- Galvanized gas pipe: Certified for natural gas and propane systems (UL 6, FM Approved).
- Galvanized handrail pipe: Combines durability with compliance to OSHA safety standards.
