Double Coupler | Scaffolding Double Coupler Manufacturer
Double Coupler for Scaffolding Systems
The Double Coupler is one of the most commonly used fittings in tube and coupler scaffolding systems. It is designed to connect two scaffolding tubes at a 90-degree angle, creating a strong and secure joint within the scaffolding structure.
As a critical component in construction scaffolding, the Double Coupler ensures that horizontal tubes (ledgers) can be firmly connected to vertical tubes (standards), providing stability and safety for workers operating at height.
Tianchang AJ Metal Products Technology Co., Ltd. (AJ Scaffold) is a professional scaffolding coupler manufacturer in China, producing high-quality forged and pressed couplers that meet international construction standards. Our products are widely used in construction projects, infrastructure development, industrial maintenance, and scaffolding rental systems worldwide.
What Is a Double Coupler?
A Double Coupler is a type of scaffolding fitting used in tube and clamp scaffolding systems to connect two steel tubes at a fixed 90-degree angle. Because it forms a rigid joint, it plays an essential role in maintaining the structural integrity of the scaffolding framework.
In most scaffolding systems, Double Couplers are used to connect:
Vertical standards and horizontal ledgers
Scaffolding tubes forming working platforms
Structural support connections
Due to its strength and reliability, the Double Coupler is widely used in construction scaffolding, industrial scaffolding, and temporary access structures.
Key Features of Double Couplers
High Strength Steel Material
Our Double Couplers are manufactured using high-quality Q235 carbon steel, ensuring strong load-bearing capacity and long service life even in demanding construction environments.
Secure 90-Degree Connection
The coupler is specially designed to connect scaffolding tubes at a right angle, creating a rigid and stable connection that enhances the overall strength of the scaffolding structure.
Forged or Pressed Manufacturing Process
AJ Scaffold offers both:
Forged Double Couplers – Higher strength and durability
Pressed Double Couplers – Cost-effective and widely used
Both types provide reliable performance for construction applications.
Corrosion-Resistant Surface Treatment
To ensure long-term durability, our scaffolding couplers are available with several surface treatments:
Electro Galvanized
Hot Dip Galvanized
Painted Finish
These treatments help protect the coupler from rust and corrosion during outdoor use.
Easy Installation
The Double Coupler can be easily installed using standard scaffolding tools, allowing workers to quickly assemble and disassemble scaffolding structures on construction sites.
