Description of Scaffolding galvanized tubes

Scaffolding galvanized tubes are a type of steel scaffolding pipe that is coated with a layer of zinc to provide rust and corrosion resistance. These tubes are essential in the construction industry, as they are used to create temporary frameworks that support workers, tools, and building materials during construction, maintenance, or repair work. Galvanized scaffold tubes are also known as scaffolding pipes and are widely used in building scaffolding, industrial and civil construction, infrastructure scaffolding, and concrete shoring.

They are part of the tube and clamp scaffolding system, fixed by scaffold fittings and connectors. These tubes are typically made from high-strength steel and are available in various lengths and specifications, including different diameters and wall thicknesses. The galvanization process enhances the durability of the tubes by protecting the steel from corrosion, which is crucial for the safety and longevity of scaffolding structures. scaffolding galvanized tubes are a critical component in scaffolding systems due to their strength, durability, and corrosion resistance, which are essential for ensuring the safety of construction projects.

Types of Scaffolding galvanized tubes

In the construction and building industry, scaffolding galvanized tubes can be categorized into two types based on manufacturing processes: welded and seamless:

Welded Scaffolding Galvanized Tubes

Manufacturing Process: Welded tubes are made by rolling metal sheets or coils into cylindrical shapes and then welding the seam along the length.
Size and Length: Welded tubes can typically be manufactured in long continuous lengths and can be customized for large diameters and thin walls, suitable for applications requiring precise dimensions.
Strength: Welded tubes generally have lower strength compared to seamless tubes.
Cost: The manufacturing cost of welded tubes is lower, and thus they are relatively cheaper.
Surface Quality: Welded tubes usually have a higher surface quality with a smoother finish.
Application: Commonly used in construction and other applications where precision is required.

Seamless Scaffolding Galvanized Tubes

Manufacturing Process: Seamless tubes are made by heating solid steel billets and extruding them into tubes without any weld seams.
Length: Seamless tubes are usually shorter in length.
Strength: Seamless tubes have higher strength and are suitable for high-pressure applications and critical structural components.
Uniformity: Seamless tubes have more uniform wall thickness.
Corrosion Resistance: Seamless tubes are more resistant to corrosion.
Cost: The cost of seamless tubes is higher.
Manufacturing Flexibility: Seamless tubes have less manufacturing flexibility.
Surface Treatment: The surface of seamless tubes may be rougher due to the extrusion process.
Size Range: The size range of seamless tubes is relatively limited.

In summary, welded and seamless tubes each have their advantages and suitable applications. Welded tubes are commonly used in general construction and building applications due to their lower cost and higher manufacturing flexibility, while seamless tubes are used in more demanding applications due to their higher strength and corrosion resistance. When selecting galvanized tubes for scaffolding, one needs to decide based on the specific project requirements and budget.

Production standards for galvanized pipes

involve multiple domestic and international standards. Here are some of the main manufacturing standards:

National Standards (GB/T):
- GB/T 3091-2015: This is the Chinese national standard that specifies the requirements for welded steel pipes for low-pressure fluid service, including galvanized steel pipes.
- GB/T 21835-2008: This is the Chinese national standard that involves the manufacturing and quality requirements for galvanized pipes.
Industry Standards (YB/T):
- YB/T 4178-2008: This is an industry standard set by the China Iron and Steel Association, applicable to hot-dip galvanized steel pipes for construction, specifying product dimensions, shapes, weights, technical requirements, etc.
International Standards (ISO):
- ISO 1461: This is a standard set by the International Organization for Standardization, concerning hot-dip galvanized steel pipes and strips, suitable for structures such as buildings, bridges, towers, etc.
European Standards (EN):
- EN39: The European standard specifies non-alloy carbon steel welded round tubes for the construction and use in building projects, including scaffolding.
- EN10219: The European standard concerns non-alloy and fine-grain steel welded round tubes, also suitable for scaffolding.
Other International Standards:
- ASTM A53: The American Society for Testing and Materials standard, concerning galvanized and non-galvanized (black) steel pipes for general purposes, such as steam, water, gas, and air conveyance.
- JIS 3444: The Japanese Industrial Standard, concerning galvanized scaffold steel pipes.
Other Mentioned Standards:
- BS 1139: The British Standard, concerning the manufacture and testing of scaffold steel tubes.
- AS 1576: The Australian Standard, concerning scaffold steel tubes.
XUDSTEEL adheres strictly to these standards, ensuring the quality and safety of the galvanized pipes they produce. By doing so, XUDSTEEL also maintain unified technical specifications that are essential for international trade. Compliance with these standards is vital for XUDSTEEL as a producer, as well as for users and international traders of galvanized pipes.
