Right Angle Coupler

Right Angle Coupler - Heavy-Duty Scaffolding Connection Solution

Shandong Xingrui Building Materials Co., Ltd. manufactures professional-grade Right Angle Coupler using Q235 premium steel with anti-slip load-bearing capacity ≥8kN. Our 90-degree vertical fixed fasteners are precisely developed for 48mm steel tube scaffolding systems to provide stability for stress distribution at orthogonal junctions. Each coupler is manufactured in our 79,800 sq. m. manufacturing plant with 12 welding robots and 6 automatic welding lines with stringent quality control supported by ISO 9001, ISO 14001 and ISO 45001 certifications. With over 920 people, including 180 skilled specialists, we guarantee dependable performance and dimensional precision on building projects across the world.

What is a Right Angle Coupler? 

This device is a load bearing fastener used to join scaffolding tubes at right angle junctions. This critical component fastens ledgers or transoms to vertical standards in tube-and-clamp scaffolding systems.

The coupler meets key industrial challenges. It avoids the structural instability of multi-level scaffolding structure. It prevents the tube from moving under severe vertical stresses. It retains the rigorous orthogonal alignment necessary for safe working platforms.

This fastener provides a permanent non-swivel connection that provides geometric integrity across the whole scaffold construction. This means the possibility of joint displacement which might lead to framework collapse is substantially reduced.

Technical Specifications

Core Performance Advantages

Our manufacturing process delivers superior connection strength. The malleable cast iron construction withstands repeated assembly and disassembly cycles without performance degradation.

Precision engineering ensures consistent fit with standard 48-series steel pipe scaffolding. You benefit from universal compatibility across different project requirements. The dedicated 90-degree design eliminates angular deviation that compromises structural integrity.

The anti-slip load-bearing capacity meets demanding construction standards. Each fastener distributes stress evenly across contact surfaces. This prevents localized pressure points that could damage scaffolding tubes.

Surface treatment protects against environmental corrosion. Your investment maintains performance integrity across multiple job sites and weather conditions.

Application Scenarios

High-Rise Building Construction: Used in multi-story scaffolding systems where vertical alignment is necessary. The coupler provides structural stability as workers and materials traverse elevated platforms.

Industrial Maintenance Projects: Scaffolding for access to machines and equipment. The robust 90-degree joint offers secure work surfaces in tight locations with uneven geometry.

Bridge & Infrastructure Work : Provides heavy-duty shoring devices that support formwork during concrete pours. The load bearing capability withstands large transient loads without sliding of joints.

Renovation and Façade Works: Allows for variable scaffolding arrangements to conform to the curves of buildings. You can open access points safely and yet have structural integrity.

Quality Control Standards

Our manufacturing facility implements comprehensive inspection protocols. Every Right Angle Coupler undergoes dimensional tolerance verification to ensure proper fit with standard tubes.

We conduct load-bearing tests on production batches. These tests confirm each fastener meets or exceeds the specified 8kN anti-slip capacity. Visual inspection identifies surface defects before products leave our facility.

Material composition analysis verifies steel grade compliance. Our quality traceability system tracks each production run from raw material to finished product. This documentation supports your project compliance requirements.

The whole quality management system encompasses raw material test, in-process control and final product check. You get fasteners that function consistently in difficult building conditions.

FAQ 

Q: Can I use these couplers for more than one project?

A: Yes, our fasteners are designed to go through several assembly cycles. Check visually for fractures or deformation before usage. Replace any parts that are worn or damaged structurally.

Q: What tube diameter do these couplers accommodate?

A: These fasteners are specifically designed for 48mm outer diameter scaffolding tubes. The precision fit ensures optimal load transfer and connection security.

Q: How do I verify proper installation?

A: Ensure the coupler fully engages both tubes at the intersection point. Tighten the fastening bolt until resistance is felt. The connection should show no movement when manually tested.

Q: What maintenance do these fasteners require?

A: Clean debris from threads and contact surfaces after each use. Store in dry conditions to prevent corrosion. Apply light lubrication to moving parts if stored long-term.

Q: Are samples available for project testing?

A: Yes, we provide product samples with technical documentation. Contact our team to arrange sample delivery for your evaluation process.
