Information
Features
Galvanized Carbon Rectangular Steel Pipes are known for their durability, strength, and excellent resistance to corrosion. The galvanization process involves applying a protective zinc coating to steel to prevent rusting. Here are some key features of these pipes:
- Corrosion Resistance: The primary feature of galvanized pipes is their resistance to corrosion. The zinc coating acts as a sacrificial layer that protects the steel underneath from rust and corrosion, thus extending the pipe’s lifespan.
- High Strength: Carbon steel is known for its high strength, and the galvanization process does not compromise this strength. These pipes can withstand high pressure and heavy loads, making them ideal for construction and structural applications.

Technology
Manufacturing galvanized carbon rectangular steel pipes involves multiple steps, starting from forming a rectangular pipe from a steel coil and finishing with a galvanizing process. Below is a general overview of the process:
- Coil Preparation: The process starts with a coil of carbon steel strip. The coil is inspected and prepared for the tube forming process.
- Uncoiling and Leveling: The coil is then uncoiled and passed through a leveler, which straightens it and removes any distortions.
- Slitting: After leveling, the coil is slit to the appropriate width, depending on the size of the tube to be formed.
- Forming: The slit steel strip is then passed through a series of roll forming stands. As the strip moves through the stands, it is gradually shaped into a tube. For rectangular tubes, the final stands will shape the tube into a rectangular profile.
- Welding: Once the tube shape is formed, the edges are welded together to create a continuous seam. Electric Resistance Welding (ERW) is commonly used.
- Cooling: After welding, the tube is cooled. This can be done using air or water.
- Sizing: Once the tube has cooled, it is passed through a series of sizing stands to ensure that it has the correct dimensions.
- Cutting: The tube is then cut to the desired length.
- Straightening: After cutting, the tubes are straightened if necessary to ensure they meet the required tolerances for straightness.
- Inspection and Testing: The tubes are inspected and tested to ensure they meet all specifications and quality standards. This can include visual inspection, as well as non-destructive testing methods such as ultrasonic testing or eddy current testing.
- Galvanizing: The formed and inspected rectangular tubes are then galvanized. This involves dipping the steel pipes in a bath of molten zinc or using a zinc electroplating process. The zinc forms a protective barrier against corrosion on the surface of the pipes.
- Finishing: The galvanized pipes may undergo finishing processes as per the requirements, including passivation or the application of a protective coating to preserve the zinc layer.
- Packing and Shipping: Finally, the tubes are bundled together and prepared for shipment to the customer.

Application
Galvanized carbon rectangular steel pipes have a layer of zinc coating, which gives them a strong resistance against corrosion. This characteristic makes them highly desirable in various applications. Here are a few typical uses:
- Construction: Their high strength, durability, and resistance to corrosion make these pipes well-suited for structural applications in buildings, bridges, fences, and other constructions.
- Plumbing: Galvanized pipes were commonly used for water supply lines in homes and businesses due to their resistance to rust. However, it’s less common today due to the use of other materials like copper or PVC, which have better corrosion-resistant properties.
- Agriculture: These pipes are used in irrigation systems, greenhouses, and other agricultural structures due to their ability to withstand the outdoor elements.
- Transportation: Galvanized pipes can be used in the manufacture of vehicles or vehicle parts, providing resistance to environmental and chemical corrosion.
- Industrial: Galvanized pipes can be used for conveying water, gas, oil, or other fluids in industrial settings, thanks to their rust-resistance.
- Outdoor Applications: Due to their resistance to weather and corrosion, these pipes are often used in outdoor applications such as billboards, street signs, and outdoor furniture.
- HVAC: Galvanized steel pipes are also used in heating and cooling systems, due to their ability to withstand high pressure and temperature.
Package
Packaging for carbon steel rectangular pipes usually depends on the length, quantity, and the requirements of the customer. The main goal of packaging is to protect the product during storage and transportation, ensuring it reaches the customer in the best possible condition.
- Bundling: The most common method for packaging is bundling, where multiple steel pipes are bound together using steel straps. Depending on the length and size of the pipes, the number in each bundle can vary.
- Wrapping: After bundling, the steel pipes can be wrapped in a plastic or waterproof paper to protect against rust and other environmental damage. This is particularly important for carbon steel, which can corrode easily if not properly protected.
- Crating: For especially large or heavy pipes, or for long-distance shipping, wooden or steel crates can be used to provide additional protection. Crating can prevent damage during loading, unloading, and transportation.
- End Protection: Caps can be placed on the ends of the pipes to protect them from damage and to prevent foreign objects from entering the pipe. This is especially important for threaded or beveled ends, which can be more susceptible to damage.
- Marking: Each bundle or crate is typically marked with identifying information, such as the size, grade, heat number, manufacturer’s name or logo, and any other information required by the customer or by shipping regulations.
