Advantages
1. The material is sturdy and durable, and the manufacturing process is exquisite
Made of pure Q235 steel (3.5mm thick), it is formed under high pressure by a hydraulic press, featuring high structural strength and strong resistance to deformation. All accessories are made of 8.8 grade high-strength steel and have passed a 72-hour atomization test to ensure corrosion resistance and durability in extreme environments, significantly extending the product's service life.
2. It strictly complies with international standards and is of reliable quality
The product has been fully certified by BS1139 (British scaffolding standard) and EN74 (EU scaffolding connector standard), and has passed the third-party testing by SGS, ensuring that each connector meets the global high standards in terms of load-bearing capacity, stability and safety, and is suitable for all kinds of high-standard construction projects.
3. Global supply chain and professional service system
Relying on the geographical advantage of Tianjin as a base for steel and scaffolding industries in China, it combines the quality of raw materials with the efficiency of logistics (close to the port, with convenient global transportation). The company offers diversified scaffolding system solutions (such as ring lock systems, copper lock systems, quick-release systems, etc.), adhering to the concept of "quality first, customer first", covering Southeast Asia, the Middle East, Europe and America markets, and has the ability to respond quickly and provide customized services.
