Heavy Duty Scaffold Coupler | Safe Load-Bearing Connector For Frame Scaffolding
以下是压缩到两句话的版本： --- ### 英文版 The Heavy Duty Scaffold Coupler is a safe load-bearing connector for frame scaffolding, joining steel pipes under heavy construction loads to prevent insufficient load capacity and joint failure. It features hot-dip galvanized protection, ≥18 kN slip resistance, EN 74 & AS/NZS 1576.2 compliance, easy bolt tightening, and anti-loosening design — ideal for high-rise frame scaffolding, heavy-load support towers, bridge falsework, and industrial plant construction.
- Product Introduction
Products Description
The Heavy Duty Scaffold Coupler is a safe load-bearing connector designed for frame scaffolding systems. It is used to join steel pipes in high-load structural scaffolding where safety and stability are critical. This product solves the problem of insufficient load capacity and joint failure under heavy construction loads, ensuring the scaffold frame remains secure. Advantages include hot-dip galvanized finish for corrosion resistance, integrally stamped body for consistent strength, high slip resistance (≥18 kN), compliance with EN 74 and AS/NZS 1576.2, easy bolt tightening without complex tools, and anti-loosening design. Ideal for high-rise frame scaffolding, heavy-load support towers, bridge falsework, industrial plant construction, and temporary structural shoring.

FAQ
Q: 1. What is the safety factor of this heavy duty coupler?
A: This coupler has a safety factor of 4:1 (based on ultimate load), meaning it is designed to withstand four times its working load limit, providing an extra margin of safety for critical scaffolding structures.
Q: 2. Can this coupler be used for suspending scaffolding or under tension loads?
A: Yes, the girder coupler type is specifically designed for tension and hanging applications, such as suspended scaffolding or overhead support systems, with a minimum slip resistance of 25 kN.
Q: 3. How are your couplers tested for quality before shipment?
A: Each batch is tested for material composition, bolt torque retention, slip resistance under load, and salt spray corrosion resistance. Test reports are available upon request.
Q: 4. Do you offer samples for project approval before bulk order?
A: Yes, we provide free samples for standard couplers (buyer pays shipping) and can produce pre-production samples for customized orders before mass production begins.
