Recommended equipment:
Measure the desired length with a tape measure and mark the cut line using a marker or utility knife.
Clamp the pipe firmly in a pipe vise. Use a pipe cutter (e.g., Virax) for a clean, square cut—tightening gradually while rotating.
Alternatives: a hacksaw or angle grinder with a metal disc—use cautiously and deburr thoroughly afterward.
After cutting:
This step ensures a clean thread start with no burrs or resistance.
Select a die that matches your pipe diameter (e.g., ½″, ¾″, 1″) with BSPT taper (ISO 7-1). Check the tool or box for BSP / R compatibility.
Apply cutting oil to the pipe end and die teeth.
Start the die square to the pipe. Turn clockwise with steady pressure, adding oil regularly.
Cut about 15–20 mm of threads, then back the die off counter-clockwise.
Wipe chips away and ensure threads are sharp, even, and burr-free.
Two effective options:
Avoid covering the first thread so sealant doesn’t clog the pipe.
Never skip this step:
If you find a leak: tighten slightly or disassemble, clean, and reseal correctly.
Threading removes the pipe’s zinc coating, exposing raw steel:

With the right tools, methodical steps, and a bit of practice, cutting, threading, and assembling galvanized steel pipes becomes straightforward. Whether for plumbing, custom furniture, or a heating network, these skills give you accuracy and independence.
Steel tubing is widely used in numerous industries, including construction, manufacturing, and infrastructure. One of the most effective methods to enhance the durability and longevity of these steel tubes is through the process of galvanization.
Understanding the Galvanization Process
Galvanized steel tubing refers to steel pipes that have undergone a galvanization process to prevent rust and corrosion. This process involves coating the steel pipe with a protective layer of zinc, creating a barrier against moisture and other corrosive elements. The resulting galvanized steel tubing exhibits enhanced durability, making it suitable for a wide range of applications.

Why Choose Galvanized Steel Tubing?
Galvanized steel tubing offers several advantages over other types of steel pipes. One of the key benefits is its excellent corrosion resistance. The zinc coating acts as a shield, protecting the steel pipe from environmental factors that can cause rust and deterioration. This makes galvanized steel tubing ideal for outdoor applications and in industries where exposure to moisture and chemicals is common. Additionally, galvanized steel tubing has a long lifespan, reducing the need for frequent replacements and maintenance. The durability and cost-effectiveness of galvanized steel tubing make it a preferred choice for many projects.
Factors to Consider When Choosing a Galvanized Steel Tubing Supplier
When sourcing galvanized steel tubing, it is crucial to partner with a reliable and reputable manufacturer. Here are some key factors to consider:
Select a supplier with a proven track record in the industry. Experience assures quality and reliability in manufacturing galvanized steel tubing.
Ensure the supplier maintains high-quality standards throughout the manufacturing process. Look for certifications and industry approvals that indicate their commitment to producing superior products.
It is important to choose a supplier who adheres to industry standards and regulations. The supplier should have a demonstrated commitment to quality control and compliance.
Consider the supplier's pricing structure and their ability to deliver products on time. A reliable supplier will offer competitive prices without compromising on quality or delivery schedule.
The Manufacturing Process of Steel Pipes
To ensure high-quality galvanized steel tubing, it is essential to understand the manufacturing process that a reliable steel pipe manufacturer follows:
A reputable manufacturer will carefully select high-quality raw materials for the production of steel pipes. This ensures the strength, durability, and corrosion resistance of the final product.
The selected raw materials are then cut and shaped into the desired dimensions and specifications. Advanced cutting and shaping techniques are used to ensure accuracy and precision.
Steel pipes can be manufactured using either welding or seamless methods, depending on the specific requirements of the project. Both methods ensure strong and reliable joints, but seamless pipes offer a smoother interior surface.
After the pipe manufacturing process, the steel pipes are submerged into a bath of molten zinc. The zinc coating forms a tightly bonded barrier over the surface of the pipes, providing exceptional corrosion resistance and extending their lifespan.
A thorough inspection is conducted on the galvanized steel pipes to ensure they meet the required quality standards. This includes checking for proper dimensions, weld integrity, and the thickness of the zinc coating.
The Versatility of Square Steel Pipes
Square steel pipes are sought after for their versatility and suitability in various applications. They offer:
1.Construction: Square steel pipes are commonly used in the construction industry for structural applications such as columns, beams, and supports.
2.Furniture: Due to their high strength and aesthetic appeal, square steel pipes are used for the production of furniture, including tables, chairs, and shelves.
3.Automotive: Square steel pipes find applications in the automotive industry for frames, chassis components, and suspension systems.
4.Signage and Display: Square steel pipes are often used to create displays, sign frames, and other decorative structures.
1.Strength and Durability: Square steel pipes offer excellent structural strength, making them ideal for bearing heavy loads and withstanding external forces.
2.Easy Fabrication: Square steel pipes are easily manipulated and welded, allowing for easy fabrication and customization to suit specific project requirements.
3.Aesthetic Appeal: The clean and modern design of square steel pipes makes them an attractive choice for architectural and design applications.
4.Cost-Effective: Square steel pipes are cost-effective due to their durability, low maintenance requirements, and long lifespan.
When selecting a steel pipe manufacturer, it is crucial to consider the following factors:
Ensure that the manufacturer follows stringent quality control measures and holds relevant certifications, such as ISO , to guarantee the production of high-quality steel pipes that meet industry standards.
Look for a manufacturer with years of experience in the industry and a good reputation for delivering reliable products. Checking customer reviews and seeking recommendations can help assess their track record.
Choose a manufacturer that offers a diverse range of steel pipes to cater to your specific requirements. This includes different sizes, shapes, and materials to meet the demands of various applications.
Consider the production capacity of the manufacturer to ensure that they can meet the requirements of your project in terms of quantity and delivery schedule. Large manufacturers may have greater production capacity and faster turnaround times. The production capacity of Yuantai Derun is approximately 10 million tons.
If your project requires customized steel pipes, ensure that the manufacturer offers fabrication and customization services. This allows for tailored solutions to specific design and application needs.Yuantai Derun Steel Pipe Group has the ability to customize steel pipes.
