Product Description

Hot - dip galvanized flange bolts are essential fasteners widely applied in numerous industries. They are designed to offer secure and long - lasting connections, especially in environments where corrosion resistance is crucial.

Structural Features

Hot - Dip Galvanizing Process

Application Scope

These bolts combine the functionality of a traditional bolt with an integrated flange. The head of the bolt is typically hexagonal, which is convenient for being tightened or loosened using a wrench. Beneath the head, there is a widened, flat flange. This flange serves as a built - in washer, effectively increasing the bearing surface area when the bolt is tightened. By distributing the clamping force over a larger area, it reduces the risk of damage to the connected materials and enhances the stability of the connection. The shank of the bolt is threaded, allowing it to be screwed into nuts or tapped holes, ensuring a firm fastening.

The hot - dip galvanizing process is the key to the outstanding performance of these bolts. First, the bolts are thoroughly cleaned to remove any impurities such as oil, rust, and dirt, ensuring a clean and reactive surface. Then, they are immersed in a bath of molten zinc at a temperature of around 450 - 480 °C. During this immersion, a metallurgical reaction occurs between the iron in the steel bolt and the zinc in the bath. A series of zinc - iron alloy layers are formed on the surface of the bolt, followed by a top layer of pure zinc. This multi - layer zinc coating is relatively thick, usually ranging from 50 to 100 micrometers, depending on the specific requirements and standards.

Due to their excellent performance, hot - dip galvanized flange bolts find extensive use in various industries
5.1 Construction Industry
In building construction, they are used for connecting structural steel members, such as in the construction of bridges, high - rise buildings, and industrial sheds. Their high strength and corrosion resistance ensure the long - term stability and safety of the structures, even when exposed to the elements. For example, in bridge construction, hot - dip galvanized flange bolts are used to connect the steel girders and supports, withstanding the combined effects of heavy traffic loads and harsh weather conditions.

Packing & Delivery

Bag Packaging

Carton Packaging

Fasteners can be packaged in durable plastic bags, which are available in various sizes to accommodate different quantities (e.g., small batches of screws, nuts, or bolts). The bags are typically sealed by heat or with a zipper to prevent moisture, dust, and loss of contents. This method is lightweight, cost-effective, and suitable for retail sales, small shipments, or situations where easy access to the fasteners is needed. Additionally, clear plastic bags allow for quick visual identification of the products inside.

For larger quantities or bulk transportation, cartons are commonly used. These are sturdy cardboard boxes, often reinforced with corrugated layers to provide protection against impact during handling and shipping. Fasteners in cartons are usually pre-packed in bags or separated by dividers to avoid friction and damage. Cartons can be labeled with product details (e.g., type, size, quantity) and are stackable, optimizing storage and logistics efficiency. This method is ideal for industrial orders, wholesale distribution, or long-distance transportation where durability is a priority.
