HANDAN, CHINA – March 26, 2026 – Handan DongChao Hardware Products Co., Ltd. announces a strategic expansion of its manufacturing capabilities with the commissioning of two new high-precision cold heading machines. This upgrade significantly enhances the company's ability to produce a comprehensive range of self-drilling screws, specifically targeting the diverse needs of the Middle East, South America, Southeast Asia, and Russian construction markets.
The new production lines are engineered to handle complex head formations and specialized materials, allowing Handan DongChao to scale up output for critical product categories including wafer head self-drilling screws, countersunk self-drilling screws, and high-aesthetic painted head and nylon head hex self-drilling screws.
Precision Engineering for Every Application
Understanding that different climates and structures require specific fastener solutions, the upgraded facility now offers enhanced versatility in both geometry and material science:
Roofing & Cladding Solutions: For the booming metal building sectors in Southeast Asia and South America, the new machines optimize the production of wafer head and countersunk head roofing screws. These designs ensure flush installation and superior water tightness for metal roofs.
Aesthetic & Corrosion Protection: Addressing the harsh coastal environments of the Middle East and island nations, Handan DongChao has expanded its capacity for painted head self-drilling screws (matching RAL color codes) and nylon head hex self-drilling screws. The precise cold heading process ensures the coating remains intact during formation, maximizing corrosion resistance.
Structural Integrity: For heavy steel structures in Russia and industrial projects in Brazil, the facility can now process alloy steel (SCM435/40Cr) alongside standard C1022 carbon steel. Utilizing advanced case hardening technology, the screws achieve an optimal balance: a tough, ductile drill point for penetration and a hardened thread/head for high torque performance, meeting the mechanical demands of Class 3 (SAE) and equivalent DIN 7504 / GOST specifications without the brittleness risks associated with improper full-hardening.
"Our clients don't just need 'screws'; they need specific solutions for their environment," said David Bao, Sales Director at Handan DongChao. "Whether it's a nylon-washer hex screw for a humid tropical resort in Thailand, a red-painted wafer head screw for a warehouse in Saudi Arabia, or a heavy-duty fastener compliant with GOST for a Siberian pipeline, our new equipment allows us to switch production modes rapidly while maintaining strict dimensional tolerances."
Global Standards Compliance
The flexibility of the new cold headers ensures seamless compliance with regional mandates:
DIN 7504 & BS 4174: Standard for Europe, Middle East, and Africa.
JIS B 1124: Critical for Japanese-funded projects in Southeast Asia.
GOST 17473 / 10618: Essential for Russian and CIS infrastructure.
NBR / IRAM: Adaptable for South American regulatory requirements.
Driving Efficiency in the Supply Chain
With a 40% increase in monthly capacity, Handan DongChao is now better positioned to support large-scale tenders. The vertical integration-from wire drawing to thread rolling, heat treatment, and surface coating (HDG, Geomet, Painting)-ensures that every roofing screw or structural fastener leaves the factory with consistent quality.
"This investment is about reliability," added Mr. Bao. "In markets like Russia and the Middle East, where logistics can be challenging, delivering the right specification-be it a countersunk self-driller or a painted hex head-on the first try is crucial. Our new lines minimize errors and maximize throughput."
