Our advantages
1. High strength and durability:
Made of high-quality pure steel, it is sturdy and reliable, long-lasting and capable of stably supporting engineering loads.
2. International Certification:
Passed international standard tests such as BS1139, EN74, and NZS 1576 to ensure safety and compliance.
3. Strong performance:
It is suitable for the connection between beams and pipes in scaffolding systems, providing stable load support and has a wide range of applications
Our shortcomings
1. High cost: Due to the use of high-quality pure steel and compliance with multiple international standards, the production cost is relatively high, which may lead to weak price competitiveness of the product.
2. Heavy weight: Although pure steel material is strong and durable, it also increases the weight of the coupling, which may require more manpower or equipment assistance during transportation and installation
