Established in 2013, Tianchang AJ Metal Products Technology Co., Ltd. (AJ Scaffolding Manufacturer) has carved a reputation as a leader in the precision manufacturing of EN74 Scaffold Clamps and modular scaffolding systems. With over 12 years of hands-on experience, we have served mission-critical sectors including China's nuclear power, petrochemical industries, and high-speed rail construction.
Our trustworthiness is backed by a track record of collaboration with global energy giants such as BASF, Shell, and ExxonMobil. Since 2018, we have expanded our reach to provide high-end contract manufacturing (OEM/ODM) for international trading partners, ensuring that every coupler meets the stringent safety requirements of the global market.

The EN74 standard is the internationally recognized benchmark for scaffolding couplers, ensuring the structural integrity of temporary works in construction and maintenance. As global urbanization accelerates, especially in Southeast Asia, the Middle East, and North America, the demand for high-quality EN74 Scaffold Clamps has reached an all-time high.
The market is shifting toward Class B (Heavy Duty) couplers which offer higher slip resistance and failure loads, essential for complex industrial structures.
Massive infrastructure projects in Saudi Arabia (Vision 2030) and railway expansions in Europe are driving bulk procurement of forged couplers.
Insurance companies and safety regulators now strictly enforce EN74-1:2005 certifications, making uncertified clamps a liability for contractors.
Innovation in the scaffolding industry is no longer just about weight; it is about durability, efficiency, and traceability. We are seeing a move toward Hot-Dip Galvanized (HDG) finishes becoming the standard over traditional electro-galvanization to combat corrosion in marine and chemical environments.
Furthermore, digitalization is entering the factory floor. At AJ Metal, we are integrating precision forging with automated assembly lines to reduce human error. The "Smart Scaffolding" trend also involves laser-etched QR codes on clamps for easier inventory management and safety inspection tracking on-site.
In coastal hubs like Singapore or Rotterdam, clamps must withstand high salinity. Our HDG EN74 clamps are the preferred choice for marine maintenance.
For nuclear and chemical plants, non-sparking and high-tensile forged couplers are mandatory. Our history with Shell and BASF proves our capability here.
Compact, lightweight pressed steel clamps are trending in European urban centers where scaffolding must be erected quickly in tight spaces.
Global wholesalers require customized packaging (Scaffolding Coupler Boxes) and reliable tracking to manage large-scale stock distribution.
We operate an independent material research institute. This allows us to control the steel chemistry from the start, ensuring our EN74 clamps have the perfect balance of ductility and strength.
Based in Tianchang, China, we leverage a robust supply chain to offer factory-direct pricing without compromising the quality expected by Tier-1 contractors.
Our ESG-focused strategy addresses the needs of modern business, utilizing energy-efficient forging processes and recyclable packaging solutions.
With custom logistics solutions and reliable tracking, we ensure your bulk orders reach any global port on schedule, minimizing project downtime.
