D type iron bracket

The D-type iron bracket is a crucial metal fastener in power systems, named for its cross-sectional shape resembling the letter "D." It is primarily used for the installation and securing of power facilities such as utility poles and towers, and is an indispensable component in the construction of transmission and distribution lines.

Its primary function in power systems is to secure crossarms to utility poles and also to secure insulators to crossarms, providing support and stability.

Product Specifications:

1. Primarily made of Q235 carbon structural steel or Q345 low-alloy steel, with stainless steel or hot-dip galvanized steel used in specialized applications. Handan Jinmai generally manufactures with hot-dip galvanized or electro-galvanized finishes, with hot-dip galvanized providing greater durability than stainless steel.

2. Size Selection: Material thickness generally ranges from 4-8mm, adjusted based on load-bearing requirements. Handan Jinmai, with its own factory, offers a wide range of sizes. Our engineers can design sizes based on the matching insulator, optimizing the design and achieving cost savings.

Production Process: 

Cutting steel sheets into desired dimensions. 

Stamping: Using a die to stamp out a D-shaped section. 

Bending: Forming the desired curvature. 

Drilling: Processing mounting holes. 

Surface treatment: Hot-dip galvanizing (Handan Jinmai's galvanizing typically exceeds national standards, with an average zinc layer of at least 65μm).

Handan Jinmai will continue to update its production processes and technologies to meet the demands of the times, integrating intelligent production into production and continuously improving materials, production processes, and quality inspections.
