Buy & Import A325 Type1 Heavy Hex Structural Bolts from Ningbo S&D Metalwork Co., Ltd. - China Wholesale Supply

The A325 Type 1 Heavy Hex Structural Bolts from Ningbo S&D Metalwork Co., Ltd. are engineered for structural steel connections in construction, bridge work and heavy machinery assembly. They meet ASTM A325 Type 1, a heat-treated carbon steel specification that delivers a minimum tensile strength of 120 ksi and a yield strength of 92 ksi for 1/2 to 1 inch diameters. The listing confirms size availability from 1/2" to 1 1/2" with a heavy hex head designed to distribute torque and prevent rounding during installation.

These bolts are typically supplied in a plain finish or with zinc plating for corrosion resistance, a standard option for outdoor or high-humidity environments. The heavy hex geometry adheres to ASME B18.2.1 dimensions, ensuring compatibility with standard wrenches and sockets. Material composition is usually medium-carbon alloy steel, quenched and tempered to achieve the required mechanical properties for structural applications.

Architects, engineers and contractors use A325 Type 1 bolts to join steel beams, columns and girders where slip-critical or bearing-type connections are specified. Buyers should confirm the exact size, finish and thread length for their project, as well as the supplier’s MOQ, packaging and incoterms. Ningbo S&D Metalwork Co., Ltd. is based in Yinzhou District, Ningbo, Zhejiang, and operates under a harbor-tier verification signal, indicating a baseline level of documented export activity.

Frequently Asked Questions About A325 Type1 Heavy Hex Structural Bolts from Ningbo S&D Metalwork Co., Ltd.
A325 Type 1 bolts are made from medium-carbon steel and are heat-treated to achieve high strength, while Type 3 bolts are weathering steel, designed for corrosion resistance in outdoor environments without additional coating. Type 1 is standard for most structural applications where atmospheric corrosion is controlled by plating or painting.

Sourcing A325 Type1 Heavy Hex Structural Bolts from Ningbo S&D Metalwork Co., Ltd. - China Import Guide

Before ordering A325 Type 1 Heavy Hex Structural Bolts from Ningbo S&D Metalwork Co., Ltd., verify the exact size, thread length and finish to match your project specifications. Request mill test certificates to confirm compliance with ASTM A325 Type 1, including tensile strength, yield strength and hardness values. Check that the supplier can provide third-party inspection reports or certificates of conformity to ensure the bolts meet international standards.

Confirm the supplier’s packaging standards, as structural bolts are typically shipped in bulk crates or palletized boxes to prevent damage during transit. Discuss incoterms such as FOB Ningbo or CIF to your port, and agree on payment terms that protect both parties. Lead times may vary based on size availability and finishing requirements, so request a production schedule for large or customized orders.

For quality assurance, conduct visual and dimensional inspections upon arrival to verify head markings, thread integrity and finish uniformity. For critical applications, arrange for third-party testing of mechanical properties, including tensile and proof load tests, to ensure the bolts meet the specified grade. Document all certifications and test results for traceability and compliance with project requirements.
