What are the installation and safety considerations?

Must be placed at all intersections, tightened to specified torque with a calibrated wrench, and regularly inspected for wear or cracks. Damaged couplers must be removed immediately.

What materials are Fixed Couplers made from?

They are typically forged from high-strength steel (e.g., EN 74-1) and often hot-dip galvanized for corrosion resistance on construction sites.

What is the main risk of using an incorrect or faulty Fixed Coupler?

The main risk is catastrophic structural failure, which can lead to scaffold collapse, resulting in serious injury, death, and property damage.

How do I identify a proper Fixed Coupler?

It will have two separate clamping assemblies forged into a single rigid body holding tubes at a fixed 90-degree relationship and cannot swivel or pivot.

AI-Powered supplier vetting

SummaryWeifang Jufeng Metal Products Co., Ltd. is a China-based limited company established in 2017, with inconsistent employee records of 5, 29, and quality-control staffing of 6–10. It offers metal stamping, fabrication, welding, punching, automotive, and related products, and is identified as a trading company despite describing its own-factory production capability. The supplier reports three production lines, stated output capacities across several product categories, broad export-market coverage, and port access through Qingdao, Tianjin, and Shanghai. It holds an ISO9001:2015 certificate and reports quality inspections during production. R&D evidence is positive: one year of total R&D-engineer experience is stated, new products were developed in the past year, and ODM plus multiple customization methods are available. However, there is no available SDK, no overseas showroom, no overseas agents or branches, no offline trade-show participation, and no overseas service countries reported. Financial...

CertificationsThe supplier explicitly reports holding an ISO9001:2015 certificate. This provides direct evidence of a certified quality-management system, although no certificate number, scope, or issuing body is supplied.

R&D capabilityThe supplier reports one year of total R&D-engineer experience, new products within the past year, ODM availability, and multiple customization methods. These are positive indicators of active product development, while the absence of an available SDK limits evidence for software or platform integration capability.

Production capacityThe supplier reports three production lines and category-specific capacities for mailboxes, metal fabrication parts, cabinets, stamping parts, and auto parts, alongside broad export-market coverage and access to Qingdao, Tianjin, and Shanghai ports. However, employee counts vary across records and the supplier is also classified as a trading company, so the scale and direct-manufacturing structure require verification.

Customization capabilityThe supplier explicitly offers OEM, ODM, smaller quantities, flexible customization, minor and full customization, customization from designs, and customization from samples. It also claims to provide exclusive and unique solutions, directly supporting a broad customization offering.

Product Q&A

Q:What is a Fixed Coupler?

A Fixed Coupler (or Rigid Coupler) is a mechanical connector designed to join two components end-to-end in a rigid, non-rotational, and non-flexible manner. Its primary purpose is to transfer load while maintaining perfect axial and angular alignment.

Q:What are its key characteristics?

Key characteristics include rigidity preventing relative movement, full load transfer capability, and ensuring connected elements form a continuous, straight member.

Q:Where is it most commonly used?

Its most famous and critical application is in scaffolding systems, specifically for connecting tubes at a 90-degree angle.

Q:How is a scaffolding Fixed Coupler different from other scaffold couplers?

Unlike Swivel Couplers that connect at any angle or Sleeve Couplers for straight lines, a Fixed Coupler connects tubes perpendicularly. It differs from Putlog Couplers which are single-sleeve clamps for non-load-bearing connections.

Q:What are other applications outside of scaffolding?

Applications include structural steelwork for connecting rebar, piping systems requiring rigidity, shaft coupling in mechanical engineering, and formwork systems.
