What Are Galvanized Steel Pipes & Tubes?

Galvanized steel pipes and galvanized tubes are carbon steel pipes that have been coated with a layer of zinc. This zinc coating acts as a sacrificial layer, protecting the base steel against corrosion and extending service life – especially in outdoor and humid environments.

Galvanized pipes: usually refers to round pipes used for fluid transport, fire lines, gas and air.
Galvanized tubes: often used for structural or mechanical applications, including square and rectangular hollow sections.
Hot dip galvanized pipes: fully dipped into molten zinc for maximum coating thickness.
Pre-galvanized tubes: produced from galvanized strip, then formed and welded for cost-effective solutions.

HL Metal offers industrial galvanized pipes for water and fire systems, galvanized tubes for construction and galvanized fence posts and scaffolding pipes for infrastructure and industrial projects.

Types of Galvanized Pipes & Zinc Coating Methods

Not all galvanized tubes and pipes are the same. Depending on coating process, thickness and base material, performance can vary. HL Metal supplies:

1. Hot Dip Galvanized Pipes

Steel pipe is fully immersed in a bath of molten zinc at controlled temperature.
Provides thick, uniform zinc layer with strong metallurgical bonding.
Recommended for outdoor installations, industrial atmospheres and coastal regions.
Typical use: galvanized water pipes, galvanized fire fighting pipes, structural supports.

2. Pre-Galvanized Tubes (Sendzimir / Strip-Galvanized)

Manufactured from pre-galvanized steel strip and then formed into tubes.
More economical for light and medium duty applications.
Common in galvanized fence posts, light structural tubes, greenhouse tubes.

3. Electro-Galvanized Pipes (On Request)

Thin, smooth zinc layer applied by electroplating.
Used in applications where appearance and tight tolerances are important.

Coating type is selected according to the corrosion class, environment (indoor, outdoor, coastal, industrial) and expected lifetime of the galvanized steel pipe installation.

Advantages of Galvanized Steel Pipes & Tubes

By choosing galvanized pipes or galvanized tubes, investors and contractors gain several technical and financial advantages:

Long-term corrosion protection: zinc acts as a barrier and sacrificial layer, slowing rust and extending pipe life.
Reduced maintenance: less frequent repainting, repair and replacement compared to uncoated steel.
Mechanical strength: retains the mechanical properties of carbon steel pipes with added corrosion protection.
Ready-to-install solution: no need for on-site painting or separate coating operations.
Versatile usage: suitable for water, air, low-pressure gas, fire fighting systems, cable protection and structural use.
Cost-effective lifecycle: slightly higher initial cost, but lower total cost of ownership over the project lifetime.

For industrial galvanized pipes in fire fighting, sprinkler and riser systems, using hot dip galvanized material can significantly reduce the risk of corrosion inside and outside the pipe.

Design & Selection – How to Choose the Right Galvanized Pipe

When designing systems with galvanized steel pipes and galvanized tubes, choosing the right combination of size, wall thickness, coating and connection method is critical.

Key Design Parameters

Medium & pressure: water, air, gas or structural use and the required pressure rating.
Environment: indoor, outdoor, coastal, industrial atmosphere or buried service.
Coating type: hot dip galvanized pipes for harsh environments; pre-galvanized tubes for light structures.
Connection: threaded galvanized pipes, grooved pipes or welded/flanged joints.
Standards: EN 10255 / EN 10240, ASTM A53, EN 10219 or project-specific norms.

If you share your isometric drawings, P&IDs or BOQ, the HL Metal team can recommend an optimal set of tube sizes, coating classes and connection accessories to keep galvanized pipe price per meter and total cost under control while meeting all technical requirements.

Galvanised Steel Pipes: The Smart Choice for Long-Lasting Applications

Galvanised steel pipes are an essential material in construction, plumbing, and industrial projects. Known for their superior corrosion resistance and strength, galvanised pipes provide a cost-effective and long-lasting solution for transporting water, gas, and other materials. Their zinc coating acts as a shield, protecting the steel core against rust and wear, even in challenging environments.

Hot Dip Galvanized Pipe: What Makes Them Special?

Galvanised pipes are steel pipes coated with a layer of zinc through hot-dip galvanisation or electro-galvanisation. This zinc layer serves two critical purposes: it prevents corrosion by acting as a barrier and sacrifices itself to protect the steel (a process known as cathodic protection).

Unlike plain steel or iron pipes, galvanised pipes require less maintenance and have a significantly extended lifespan. They are widely used in outdoor settings and in areas exposed to moisture, making them a trusted choice for builders and engineers worldwide.

Zinc Coated Steel Pipe, GI pipe

Galvanized iron pipes, are a staple in construction projects, especially where structural strength and corrosion resistance are crucial. Common applications include scaffolding, fence posts, guard rails, and handrails. In the plumbing industry, galvanised pipes are often used for water supply lines and outdoor drainage systems.

In industrial settings, galvanised pipes serve in manufacturing plants, warehouses, and agricultural environments where exposure to chemicals, moisture, or mechanical impact demands robust and durable materials.

Key Advantages of HDG pipe

Corrosion resistant steel pipe, offer several unmatched advantages:
Exceptional Corrosion Resistance: Thanks to their zinc coating, galvanised pipes withstand harsh weather, chemical exposure, and mechanical damage.
Long Service Life: Galvanised pipes often last decades, reducing replacement frequency and maintenance costs.
Cost Efficiency: While they offer performance similar to stainless steel, galvanised pipes come at a lower price, making them ideal for large-scale projects.
Ease of Use: Galvanised pipes can be easily cut, welded, and installed, providing flexibility in various applications.

Galvanized hollow section remain one of the best choices for construction, plumbing, and industrial applications. Their resilience, affordability, and versatility make them a top-tier material for projects big and small. Whether you need galvanised pipes for structural work or fluid transport, sourcing from a reputable supplier ensures you receive premium quality and expert guidance.

Pipes and Their Types

Pipes are cylindrical profiles used for transporting liquids, gases, or solids, as well as for providing structural support in various construction and industrial systems. Depending on the material and intended application, there are many types of pipes available. The most common types include steel pipes, galvanized pipes, stainless steel pipes, plastic pipes (such as PVC, PPRC, and PE), copper pipes, and aluminum pipes.

Steel pipes are preferred in heavy-duty industrial and construction applications due to their strength and durability. Galvanized pipes, coated with zinc, are resistant to corrosion and commonly used in fencing, scaffolding, greenhouse frames, and drainage systems. Stainless steel pipes are ideal for chemical, food, and medical industries thanks to their high corrosion resistance.

Plastic pipes are widely used in potable water, wastewater, and heating systems. Their lightweight nature, ease of installation, and resistance to chemical corrosion make them a popular choice. Copper pipes are valued in HVAC and refrigeration systems for their durability and excellent thermal conductivity.

Pipes can also be categorized as welded or seamless, based on their manufacturing method. Depending on the application, pipes vary in diameter, wall thickness, surface coating, and shape—such as round, square, or rectangular. Selecting the right type of pipe is critical for ensuring the efficiency, safety, and longevity of any system or structure.
