Handan Yuanbo Metal Products Co., Ltd.

Handan Yuanbo Metal Products Co., Ltd. is based in Handan, China and lists six active product lines in its catalogue. The company focuses on metal fasteners and related construction hardware, covering hexagonal bolts, heavy hexagonal bolts, stud bolts, thread rods, anchor bolts and a general fasteners category. These items fall under the standard fastener HS chapter 7318, which is used globally for bolts, screws and similar hardware. All six products are manufactured from carbon‑steel alloys commonly supplied in metric dimensions. The catalogue reflects a concentration on mechanical joining components for industrial and agricultural applications.

The product set aligns with typical bolt grades such as 8.8, 10.9 and 12.9, which define tensile strength in MPa and are referenced in ISO 898‑1 and DIN 933/934 standards. Heavy‑hex bolts are often supplied in lengths from 20 mm to 200 mm and diameters from M6 to M36, while stud bolts and thread rods are offered in continuous lengths that can be cut to order. Anchor bolts frequently meet ASTM A307 or A325 specifications for concrete anchoring. Fasteners in the broader category may include plain carbon steel, galvanized or stainless steel finishes, each requiring distinct corrosion‑resistance testing. Typical packaging includes steel pallets or wooden crates, with each pallet holding up to 1 ton of product for 20‑ft container loading.

The catalogue’s six items cover the core fastener types used in structural steelwork, machinery assembly and agricultural equipment. Hexagonal bolts and heavy‑hex bolts are standard through‑hole fasteners that conform to metric thread profiles (M‑series) and are supplied in grade 8.8 or higher. Stud bolts and thread rods provide continuous threading for tensioning applications and are often cut to custom lengths on request. Anchor bolts are designed for embedding in concrete foundations and typically include a square or round head with a threaded shank. The generic “Fasteners” entry can encompass washers, nuts and other ancillary components that complement the primary bolt range.

In the fastener market, buyers usually specify material grade, tensile strength, surface treatment (zinc plating, hot‑dip galvanizing, or stainless finish) and dimensional tolerances of ±0.02 mm. For construction‑grade bolts, compliance with ISO 898‑1, ASTM A325/A490, or EN 14399 is common, while agricultural machinery often requires corrosion‑resistant stainless steel (AISI 304/316) to withstand exposure. Standard packaging sizes are 25 kg bags for smaller bolts and bulk pallets for larger studs, facilitating 20‑ft or 40‑ft container loading with typical weights of 18 - 22 tons per container.
