Import Drawn Arc Stud — Buy in Bulk from Supplier in Taiwan

The Drawn ARC stud from Cosp Tech Co., Ltd. is a precision-engineered fastener designed for structural welding onto steel substrates in composite and metal decking applications. The studs are cold drawn from low-carbon steel with a controlled carbon content between 0.15% and 0.25%, ensuring ductility and weldability. Dimensions follow standard ISO 13918:2020, with typical diameters ranging from 10 mm to 19 mm and lengths from 25 mm to 75 mm, matching common deck thickness requirements in commercial construction.

The surface is coated with a zinc-nickel alloy, typically applied at 8 to 12 micrometers, providing corrosion resistance suitable for indoor and sheltered outdoor environments. This coating is not galvanized but meets the salt spray performance of ASTM B117 for at least 48 hours. The stud shank is drawn to a smooth finish with a tolerance of ±0.05 mm on diameter, ensuring consistent arc stability during welding. These characteristics align with industry norms for structural fasteners used in seismic zones and high-load applications.

These studs are purchased by structural engineers, steel fabricators, and EPC contractors for use in multi-storey buildings, bridges, and industrial facilities where shear connection between steel beams and concrete slabs is required. Buyers typically order in batches of 5,000 to 50,000 pieces, packed in sealed plastic bags inside cartons with moisture absorbers. Trade terms are negotiable, with FOB Kaohsiung being the most common. Lead time is generally 3 to 4 weeks after order confirmation. Certification documentation is available upon request but not pre-issued.

Cosp Tech Co., Ltd. is based in Kaohsiung, Taiwan, and operates as an importer and distributor of industrial fasteners. The company’s address is registered at No. 46, Lane 85, Zhongdu St., Sanmin District. It is listed as an imported supplier with harbor trust tier, indicating it has passed basic trade verification but does not claim manufacturing capability. The listing shows no response rate or average response time, suggesting limited direct communication capacity.

The company does not state any production facilities, certifications, or years in operation. It does not claim to manufacture the studs but sources them from external suppliers, likely in mainland China or Southeast Asia. Buyers should treat this entity as a trade intermediary rather than a producer. No client list, export history, or quality control procedures are disclosed. Verification of product origin and compliance must be requested directly before placing an order.
