FAQS
1.Q: What are British standard forged scaffold couplings? What standards does it meet?
A: British standard forged scaffold couplings are key components used to connect steel pipes and build support scaffold systems. Our products are strictly manufactured in accordance with the international standards of BS1139 and EN74, ensuring their safety, interchangeability and high load capacity. They are the preferred choice in markets such as Europe, America and Australia.
2. Q: What are the differences between forged fasteners and die-cast fasteners?
The main differences lie in the manufacturing process and strength. Forged fasteners are formed through high-temperature forging, featuring a denser molecular structure, higher strength and durability. They are suitable for heavy-duty support projects such as oil and gas, shipbuilding and large storage tank construction. Die-cast fasteners are typically used in general buildings with lower load requirements.
3. Q: In which industries and projects are your forged fasteners mainly applied?
Our forged fasteners are renowned for their outstanding load-bearing performance and extremely long service life, and are widely used in various heavy industries and complex projects, including but not limited to: oil and gas platforms, shipbuilding, large storage tank construction, power plants, and support for the main structures of large buildings.
4. Q: What standard fasteners do you provide? Can fasteners of different standards be mixed and used?
A: We produce fasteners of various standards, including British standard, American standard and German standard, etc. Fasteners of different standards may have minor differences in size, appearance and weight. It is not recommended to mix them. Please select the corresponding standard products in accordance with the norms and requirements of your project location to ensure the safety and stability of the entire scaffolding system.
5. Q: As an international buyer, what are the logistics and geographical advantages of cooperating with Tianjin Huayou?
A: Our company is located in Tianjin, the largest production base of steel and scaffolding products in China. Meanwhile, Tianjin is an important port city, which provides us with great logistics convenience, enabling us to transport goods efficiently and quickly to markets all over the world, including Southeast Asia, the Middle East, Europe and the Americas, effectively ensuring the progress of your project.
