HDG Steel Plate Connecting Strip

A HDG steel plate connecting strip, often referred to as a hot-dip galvanized steel plate connecting strip, is a fabricated component used to join steel plates together. It provides a structural connection, typically in applications where welding is undesirable, impractical, or requires reinforcement.

Material:

• Base Steel: Commonly manufactured from carbon steel such as ASTM A36, Q235, or equivalent. The specific grade depends on the load-bearing requirements and application.
• Galvanization: The 'HDG' designation signifies hot-dip galvanization. This is a process where the steel is coated with a layer of zinc to prevent corrosion. The zinc acts as a sacrificial anode, protecting the underlying steel even if the coating is scratched or damaged. Coating thickness is specified by standards like ASTM A123.
• Optional Coatings: Paint systems are often applied over the galvanization for additional corrosion protection, particularly in harsh environments.

Purpose:

• Joining Steel Plates: The primary function is to provide a mechanical connection between steel plates without the need for direct welding.
• Load Transfer: Distributes stresses and loads across the connection, ensuring structural integrity.
• Reinforcement: Can augment the strength of existing steel plate connections.
• Repair: Used in repairing damaged steel structures.

Function:

The strip is typically fastened to the steel plates using bolts, rivets, or other mechanical fasteners. The strip's width and thickness are determined by the anticipated load and the thickness of the plates being joined. The fasteners are installed through pre-drilled holes in the strip and the plates. The galvanized coating protects the entire assembly from corrosion.

Usage Scenarios:

• Shipbuilding: Connecting hull plates, deck plates, and other structural components.
• Bridge Construction: Joining bridge girders, deck plates, and bracing elements.
• Heavy Equipment Manufacturing: Connecting plates in the construction of excavators, cranes, and other machinery.
• Structural Steel Fabrication: General structural connections in buildings and other infrastructure.
• Repair and Modification of Steel Structures: Strengthening or repairing existing steel plate connections.
• Tank Construction: Joining plates in the fabrication of storage tanks.

Common Types/Configurations:

• Flat Strip: The most common type; a simple, flat piece of galvanized steel.
• Angle Strip: An L-shaped strip used for corner connections or to provide additional support.
• T-Strip: Used for connections where a perpendicular plate needs to be joined.
• Splice Plates: Specifically designed for joining the ends of steel plates together, often used to extend the length of a plate.
• Custom Fabricated Strips: Designed and manufactured to specific project requirements, including holes, notches, and other features.
• Perforated Strips: Strips with pre-drilled holes for ease of fastening and alignment.
