Import Cold Pressing Coupler — Buy in wholesale FOB from Supplier in China

The cold pressing coupler from Hebei Yida United Machinery Co., Ltd. is a mechanical splicing system designed for joining reinforcing steel bars in construction, eliminating the need for overlapping or welding. This model is engineered for parallel thread connections, compatible with rebar grades up to HRB500 and diameters typically ranging from 16mm to 40mm, as standard in the manufacturer’s production line. The coupler’s cold-forged steel construction ensures high tensile strength, with a minimum yield of 400 MPa and ultimate tensile strength of 600 MPa, meeting GB/T 232 and GB/T 228 standards for mechanical properties.

Manufactured in Shijiazhuang, Hebei Province, the coupler undergoes precision threading using the supplier’s in-house parallel thread cutting and rolling machines, which deliver consistent pitch and tolerance control. The surface treatment includes a standard zinc coating (5-15 µm) for corrosion resistance, with optional hot-dip galvanising available for harsh environments. The product is supplied in bulk packaging of 500 pieces per wooden crate, with each crate weighing approximately 200 kg, a typical configuration for export shipments.

Cold pressing couplers are primarily used in large-scale infrastructure projects such as bridges, tunnels, and high-rise buildings, where structural integrity and load-bearing capacity are critical. Buyers include EPC contractors, construction firms, and distributors sourcing for national projects, with the supplier’s past deliveries including applications in nuclear power plants and hydropower stations. The coupler’s design simplifies on-site assembly, reducing labour time by up to 40% compared to traditional methods, and is compatible with ISO 9001:2008 and BS EN ISO 9001 certified quality management systems.

Hebei Yida United Machinery Co., Ltd. is based in Shijiazhuang, Hebei Province, with its factory located at No. 6 Dongning Road in the Gaocheng District’s Economic and Technological Development Area. The company specialises in the design and manufacture of rebar splicing solutions, including couplers, upset forging machines, and thread cutting/rolling equipment, with operations spanning over three decades since its establishment in 1992.

The supplier holds ISO 9001:2008 certification and UK CARES Quality Management System Certification to BS EN ISO 9001, reflecting its adherence to international quality standards. Its product range has been deployed in high-profile projects such as the HK-Macao-Zhuhai Bridge and Pakistan’s Karachi Nuclear Power Plant, demonstrating capability in large-scale infrastructure.
