In the modern construction era, the 3.9-meter scaffold board (equivalent to the standard 13ft length) has emerged as the global benchmark for heavy-duty scaffolding systems. As urbanization accelerates across Southeast Asia, the Middle East, and Europe, the demand for standardized, high-strength steel planks has surpassed traditional timber alternatives.
The industrial scaffolding market is projected to grow significantly by 2030, driven by large-scale infrastructure projects. 3.9m boards are the preferred choice for bay lengths in Ringlock and Cuplock systems.
With tightening safety regulations (BS1139, EN12810), enterprises are moving away from wood due to fire risks and structural degradation, favoring hot-dip galvanized steel.
Steel planks offer 100% recyclability and a lifespan 5-10 times longer than timber, aligning with global ESG (Environmental, Social, and Governance) goals.
Established in 2013, Tianchang AJ Metal Products Technology Co., Ltd. (AJ Scaffolding) has built an ironclad reputation by serving the most demanding sectors in China and beyond. Our journey began with Nuclear Power Construction and has expanded into chemical plants, shipbuilding, and high-speed railways.
We are the trusted manufacturing partner for global giants like BASF, Shell, and ExxonMobil, providing specialized scaffolding solutions that meet the highest international safety thresholds.

Years Industrial Experience
Global procurement teams now demand specific perforation patterns for anti-slip performance and custom widths to fit proprietary system scaffoldings. AJ Metal excels in tailoring 3.9m planks to precise regional specifications.
In offshore and shipbuilding applications, standard painting is no longer sufficient. The trend is moving toward Hot-Dip Galvanization (HDG), ensuring the boards withstand saline environments for decades.
Using high-grade structural steel allows for thinner yet stronger boards, reducing the labor cost during assembly and decreasing the overall load on the scaffolding structure.
Batch tracking and QR code integration on boards for maintenance records is a rising requirement for Tier-1 contractors in Europe and North America.
As a leading Chinese manufacturer, AJ Metal offers a unique blend of Cost-Efficiency and High-End Engineering. Our advantage lies in our end-to-end supply chain control and our experience in China's most complex nuclear and chemical projects.
We operate an independent material research institute to develop steel alloys that balance ductility and load-bearing capacity.
Our Quality Management System ensures that every 3.9m board leaving our factory is inspected for weld integrity and galvanization thickness.
Located in Tianchang, we leverage China's world-class logistics infrastructure to provide quick delivery to major ports, ensuring your project timelines are met.
Providing safe walking platforms for skyscrapers in burgeoning cities like Dubai, Singapore, and New York.
