Hot Dipped Galvanized Structural Steel Pipe 48.3x2.4mm for Scaffolding Pipes
YTDR Group's Hot-Dipped Galvanized Structural Steel Pipe is a premium building material engineered for durability and performance. Specifically sized at 48.3mm (outer diameter) x 2.4mm (wall thickness), this pipe is the cornerstone of safe, long-lasting scaffolding systems and structural frameworks.
The core of its superiority lies in the Hot-Dipped Galvanization (HDG) process. Unlike post-fabrication galvanizing, our pipes are immersed in a bath of molten zinc after forming, ensuring a uniform, metallurgically bonded coating that covers every surface, inside and out, including the edges. This creates a robust physical barrier and cathodic protection, sacrificially protecting the underlying steel even if the coating is scratched.
Key Specifications & Standards:
● Material: High-Strength Low-Alloy Steel (Q355B / S355JR or equivalent)
● Standard: Complies with ASTM A500 Grade C and EN 10219-1/2 for structural tubing.
● Galvanizing Standard: Conforms to ASTM A123, ensuring a minimum zinc coating thickness of 85μm.
● Key Performance: Yield strength ≥ 345 MPa, excellent corrosion resistance (can withstand over 1000 hours in a salt spray test), and superior weldability.
We offer this product in standard 6-meter lengths but provide extensive customization for cutting, threading, and other specifications to meet your project's exact blueprint.
Manufacturing Excellence
With over 15 years of specialized experience in steel pipe manufacturing, our vertically integrated facility controls every step from raw material to finished product, guaranteeing consistency and quality.
Uncompromising Quality Control
Our "Zero-Defect" philosophy is enforced through 3-stage inspection protocols (raw material, in-process, final). This rigorous system results in a product defect rate of less than 0.1%, minimizing costly on-site rejections and delays for our 500+ global clients.
Cost-Efficiency & Speed
Our efficient production lines and large-scale raw material procurement allow us to offer highly competitive pricing and lead times 15-20% faster than the industry average. We help you reduce the total lifecycle cost of your assets.
Superior Service & Support
We are your technical partner. Benefit from our 24-hour responsive quotation service, dedicated project management, and expert technical support for application design and installation challenges.
Routine Cleaning
● Simple water rinsing or dry cloth wiping
● Mild detergent for stubborn stains
● No specialized equipment required
Service Life
The investment in our HDG pipe pays off for decades. The service life is directly linked to the zinc coating thickness and the environment.
● Rural/Inland Environments: 25-30 years to first significant maintenance. The zinc layer slowly weathers, providing long-term protection.
● Urban/Coastal Environments: 15-20 years in moderate to high corrosion settings. The thick 85μm+ coating effectively resists salt and industrial pollutants.
● Comparative Advantage: This is a 3-5x longer lifespan compared to painted or non-galvanized steel pipes, which can show rust in as little as 2-5 years in harsh conditions.
This longevity is rooted in the sacrificial protection of the zinc layer and the toughness of the S355JR-grade steel base, which prevents cracking and ensures structural integrity. A testament to this is a Southeast Asian client's outdoor warehouse framework erected in 2012 using our pipes, which, upon inspection in 2024, shows no signs of structural corrosion.
Application Channels
Construction Field
It is used for structural frames, support columns, outdoor advertising displays, building facades and sunshades. Its advantage lies in excellent corrosion resistance for exterior applications.
Manufacturing Field
It can be made into machine frames, protective devices, conveyor system supports and equipment structures. Its advantage is a clean appearance with built-in protective performance.
Transportation Field
It is suitable for vehicle chassis components, container frameworks and loading bay structures. Its advantage is a high strength-to-weight ratio.
Furniture & Agriculture Field
It can be used to create outdoor furniture frames, greenhouse structures and storage system supports. Its advantage is easy fabrication and aesthetic appeal.
