Established in 2013, Tianchang AJ Metal Products Technology Co., Ltd. (AJ Scaffolding Manufacturer) has evolved from a local specialist into a global powerhouse in the scaffolding industry. For over 12 years, we have provided high-precision OEM Putlog Clamp solutions to complex infrastructure projects including nuclear power plants, chemical refineries, and large-scale shipbuilding across the world.
Our journey began by serving prestigious multinational corporations like BASF, Shell, and ExxonMobil. These partnerships honed our commitment to the highest safety standards and quality management systems. Today, we operate a 12,000 m² modern production base, where every Putlog clamp and coupler undergoes rigorous fatigue testing—over 50,000 cycles—to ensure absolute reliability on-site.
Compliance with EN12810 and international safety norms. Our products are engineered for maximum load-bearing capacity.
Independent material research institute focused on alloy durability and anti-corrosion technology (Hot-Dip Galvanization).
Over 37,800 satisfied customers globally. Custom logistics solutions with real-time tracking for zero-delay delivery.
The Putlog Clamp, often referred to as a "single coupler," is a critical component in tube and fitting scaffolding. Unlike double couplers that carry heavy loads, Putlog clamps are specifically designed to connect transoms or putlogs to ledgers. In the current global construction market, particularly in high-density urban areas like London, Dubai, and Singapore, the demand for versatile and reliable Putlog clamps is surging.
As construction projects become more vertical and complex, the safety of temporary structures is non-negotiable. Industrial giants now demand Drop Forged components over traditional cast iron because of their superior tensile strength and resistance to cracking under extreme weather conditions.
Eliminate the middleman. By sourcing directly from our China factory, you get wholesale pricing without compromising on material grade or precision.
We provide full customization. Whether you need your logo embossed on the Putlog clamps or specific dimensions for unique tube diameters, our engineering team delivers.
Located near major shipping hubs, we offer rapid transit to Europe, the Middle East, and the Americas, backed by 24/7 customer support.
Global procurement officers face the challenge of balancing cost with site safety. Our OEM Putlog Clamp solutions address this by offering "Tier-1 Quality at Factory Rates." We understand the localized application scenarios—from the humid, corrosive environments of coastal oil rigs in the Gulf to the sub-zero temperatures of railway tunnels in Northern Europe. Our scaffolding is designed to perform everywhere.
Precision-engineered systems for skyscrapers and vertical urban developments.
Meeting the strict safety protocols of Shell and BASF chemical construction.
