Engineered for high-strength steel framing, infrastructure restoration, and industrial assembly across the Damascus Governorate.
Understanding the local demand, operating environments, and structural parameters required for municipal and private sectors.
Damascus, as one of the oldest continuously inhabited cities in the world, is undergoing critical infrastructural renewal. Rebuilding projects in suburban municipal sectors and historic quarters demand high-performance mechanical fasteners that meet rigorous safety standards. Fasteners are the unsung heroes of this transformation, holding together structural steel skeletons, plumbing pipelines, electrical wiring grids, and building envelopes.
In municipal rehabilitation sites, high-strength structural bolts and specialized drywall screws are deployed to secure drywall partitions, acoustic panels, and modular framework. Due to the high dust load and seasonal temperature fluctuations characteristic of the Damascus Basin, fasteners must possess superior coating integrity (such as white-blue zinc plating or phosphate passivations) to prevent premature thread seizure and hydrogen embrittlement.
Faced with municipal grid shortages, businesses and residential developers across Damascus have rapidly transitioned to solar photovoltaic (PV) systems. Mounting solar panel racking onto corrugated metal sheets requires specialized, leak-proof fastening solutions. This is where high-quality color-galvanized hexagonal self-drilling screws with integrated EPDM washers become vital.
These fasteners prevent galvanic corrosion between the aluminum frame of the PV panels and the underlying galvanized steel support structures. The self-drilling tip is engineered to puncture sheet metal without pre-drilling, ensuring rapid installation and high pull-out resistance against the strong wind loads experienced in desert fringe zones surrounding Damascus.
Located on the outskirts of Damascus, Adra Industrial City hosts manufacturing facilities ranging from food processing plants to heavy metallurgy and plastics production. Industrial machinery operates under high vibration, requiring self-locking fasteners like nylon lock nuts (DIN 985) and spring washers (DIN 127) to maintain joint integrity.
For chemical and heavy manufacturing environments, standard carbon steel is insufficient. Engineers specify black zinc oxide and high-tensile alloy fasteners designed to resist local chemical vapors, high operating temperatures, and mechanical shear. Maintaining a reliable supply of these components is crucial to preventing manufacturing downtime in these vital economic zones.
Procurement departments in Damascus face unique logistical challenges. Securing direct supply lines from high-capacity manufacturing centers like Yongnian, China, requires clear planning. Key specifications such as thread Pitch (coarse vs. fine), tensile class (4.8, 8.8, 10.9, 12.9), and corrosion resistance hours (salt spray testing) must be documented to facilitate customs clearance at Syrian ports (Lattakia and Tartous) and transport through to Damascus.
By partnering with established manufacturers like Dongshuo, buyers can guarantee conformity to international standards (ISO/DIN/ANSI) and ensure all shipments are backed by Mill Test Certificates (MTC) and quality reports.
Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd.
Established in 2015, Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. is a premier enterprise specializing in the design, engineering, and mass production of industrial fasteners. Strategically located in the Yongnian District of Handan City—widely recognized as the Fastener Capital of China—our company is committed to providing high-quality products and comprehensive engineering solutions for customers across diverse global markets, including the Levant and the Damascus reconstruction sector.
As a reputable and authoritative fastener manufacturer, we operate advanced cold heading machines, thread rollers, automatic heat-treatment furnaces, and surface finishing production lines. Our technical team works continuously to meet our customers' specific needs for standard, non-standard, and customized structural components. Through strict quality control processes, we ensure reliability for demanding projects worldwide.
The strategic supply chain advantage of the Yongnian Fastener Cluster for international buyers.
Operating in Handan allows direct partnerships with nearby major steel mills. We secure high-grade wire rods (C1022A, Q235, 35K, 45#) with consistent metallurgical purity, stabilizing raw material costs and production lead times.
Our automated heat treatment lines achieve precise carbon distribution and core hardness. This prevents head breakage during high-torque installations of self-drilling screws on metal roofs.
We utilize automated optical sorting machines to inspect dimensions, thread pitch, and recess depth. This prevents damaged screws from reaching assembly lines, supporting efficient installation processes.

We primarily utilize high-purity C1022A carbon steel for our self-drilling and drywall screws. This material is case-hardened during heat treatment to achieve a surface hardness of 560 HV minimum and a core hardness of 270-420 HV, ensuring reliable drilling capability without head shear.
We coordinate logistics from our factory in Yongnian, Handan, to major Chinese ports like Tianjin or Qingdao. From there, ocean freight shipments run to Mediterranean entry points such as Lattakia or Tartous. We prepare detailed commercial invoices, packing lists, Mill Test Certificates (MTC), and certificates of origin to support customs clearance.
