We are a professional threaded studs manufacturer, specializing in the production of partially threaded studs and weldstuds designed for structural, mechanical, and civil engineering applications.
Our main product range includes:
Partially Threaded Studs — combine threaded and unthreaded sections to provide both tension and shear resistance, ideal for anchor and machinery applications.
Weld Studs (Weldstuds) — directly welded onto steel plates or structures, ensuring high-strength attachment for bridges, decks, and foundations.
Customized Studs — available in materials such as ASTM A193 B7/B7M, A320 L7, stainless steel SS304 & SS316, and low alloy steel, with surface finishes including hot-dip galvanizing, mechanical zinc plating, and chromate-free passivation.
Building & Structural Engineering — base plates, shear wall connections, and concrete anchoring with partially threaded studs.
Bridges & Highways — weldstuds for composite connection between steel beams and concrete decks.
Machinery & Equipment — threaded studs for heavy-duty machines, vibration equipment, and mining motors.
Petrochemical & Offshore Platforms — SS316 weldstuds resist corrosion in salt and chemical environments.
Steel Fabrication & Modular Construction — partially threaded studs enable fast installation and reduce labor costs.
Bridge Project: 5,000 pcs weldstuds (Ø16 × 120 mm, hot-dip galvanized) supplied for steel-concrete composite connections, reducing construction time by 15%.
Petrochemical Facility: Replaced traditional bolts with M20 × 100 mm partially threaded studs, improving pre-tension reliability and reducing downtime by 30%.
High-Rise Equipment Foundation: As a trusted threaded studs manufacturer, our M12 × 150 mm studs delivered high torque consistency and less than 2° installation deviation.
100% quality-controlled production with ISO certification
Precise cold forging & CNC threading technology
High-tensile strength with corrosion-resistant coatings
Flexible production from prototype to mass order
