About Girder Coupler

A girder coupler is a type of mechanical fastener used to connect two girders together. It is typically used on construction sites to allow workers to construct large structures from multiple girders. A girder coupler typically consists of two metal plates connected with a pin or a threaded rod. The plates are designed to fit over the flanges of two girders and the pin or rod is used to hold the plates together. In some cases, a girder coupler may also include a locking mechanism to help ensure the connection is secure.

High Strength and Durability

Designed with a U-shaped profile and clamp, the girder coupler is crafted from high-quality forged steel or malleable iron, offering impressive strength and long-lasting durability. The robust engineering ensures a secure connection between scaffold tubes and steel girders, even under heavy loads up to 30kN, meeting the safety requirements of complex construction projects.

Wide Compatibility and Easy Installation

Fitting girder flange widths from 100 mm to 150 mm and usable with M16 or M20 bolts, this coupler accommodates a broad range of scaffolding and girder sizes. Its straightforward design-comprising two halves, hex head bolts, and nuts-enables fast, simple installation, reducing setup time and labor costs at the worksite.

Certified Quality and Weather Resistance

All units undergo 100% inspection before leaving the factory, ensuring reliable performance and safety. The coupler's hot-dip galvanized or zinc-plated finish resists corrosion, making it suitable for harsh weather and demanding environments. Its temperature resistance from -40C to 110C further guarantees dependable functionality in various climates.

FAQ's of Girder Coupler:

Q: How is the girder coupler typically installed on construction sites?

A: The girder coupler is installed by placing its two halves on either side of the girder flange, inserting the scaffold tube, and fastening the assembly using the provided hex head bolts and nuts. The design allows for a secure right-angle connection without specialized tools.

Q: What types of scaffolding applications are best suited for this girder coupler?

A: This girder coupler is ideal for situations where scaffold tubes need to be attached securely to steel girders, typically used in building, industrial, and infrastructure projects that require high strength and safety.

Q: When should I choose a hot-dip galvanized finish over zinc plating?

A: Hot-dip galvanizing is preferable for outdoor or highly corrosive environments due to its superior corrosion resistance, while zinc plating is suitable for less demanding indoor conditions. Your choice depends on your project's exposure to weather and corrosive substances.

Q: Where are these girder couplers manufactured and tested?

A: These girder couplers are manufactured, tested, and quality-inspected in India. Every unit undergoes 100% inspection at the factory before dispatch to ensure adherence to quality and safety standards.

Q: What is the benefit of having a right-angle (90) coupling with this girder coupler?

A: The right-angle configuration enables scaffold tubes to be attached perpendicular to girders, enhancing structural integrity and stability in scaffold assemblies. This design is essential for safe and compliant scaffold constructions.

Q: How does the product's temperature resistance enhance its usability?

A: With a temperature resistance range from -40C to 110C, the coupler remains reliable in extreme cold or heat, allowing for safe use across various geographic locations and weather conditions.

Q: What are the advantages of using forged steel or malleable iron in the construction of this coupler?

A: Forged steel and malleable iron both provide high mechanical strength, durability, and impact resistance, making the coupler robust enough to support heavy scaffolding loads while maintaining long service life.
