Zhangzhou Yunmaotong Import and Export Co., Ltd.
Product Overview
As the core load-bearing fitting for heavy-duty scaffolding systems, our YMT drop forged right angle scaffolding coupler (also known as forged double coupler) is the industry standard for high-safety construction scenarios. It is specially designed for 90° perpendicular rigid fixed connection between scaffolding vertical standards and horizontal ledgers, forming the core stable frame of the entire scaffolding system. Made of one-piece hot forged high-strength carbon steel, it completely solves the pain points of cast iron couplers such as easy fracture, poor impact resistance and short service life in repeated disassembly and assembly, and is the preferred choice for global scaffolding rental companies, high-rise building contractors and heavy engineering projects.
One-Piece Hot Forging Process for Ultra-High Strength: Adopting integrated hot die forging molding process with high-quality Q235 carbon structural steel, the material grain is refined and compact, eliminating casting defects such as pores, sand holes and looseness. The tensile strength, impact resistance and fatigue resistance are more than 40% higher than cast iron couplers, and it will not break or deform under sudden heavy load and harsh construction environment.
EN74 BS1139 Highest Standard Compliance: Strictly manufactured in accordance with the highest level of European EN74 and British BS1139 standards, passed ultra-high load, anti-slip, anti-torsion and impact resistance professional tests, with a minimum breaking load of ≥25KN, which exceeds the standard requirements, and fully meets the safety specifications of global heavy engineering and high-altitude operations.
Reinforced Anti-Loosening & Anti-Slip Design: Optimized high-torque T-bolt and flange nut locking structure, with anti-loosening treatment, which can maintain stable locking force under long-term construction vibration and dynamic load; the inner wall is integrally forged with dense anti-slip teeth, which fits the 48.3mm standard scaffolding steel pipe 360° closely, and the anti-slip performance is 50% higher than cast iron couplers, no displacement and no loosening under heavy load.
Suitable for Long-Term Repeated Use in Rental Business: Excellent anti-fatigue performance, can withstand thousands of times of disassembly and assembly without plastic deformation, and the service life is more than 3 times that of cast iron couplers; standard thickened hot-dip galvanized surface treatment, the zinc layer is uniform and dense, not easy to fall off, can effectively resist rust and corrosion in humid, coastal and harsh outdoor environments, greatly reducing the comprehensive use cost of scaffolding rental companies.
Stable Bulk Supply & Consistent Specifications: Fully automated forging production line, with a monthly capacity of 300-500 tons, can meet the large-scale long-term procurement needs of scaffolding rental companies and heavy engineering general contractors; strict full-process dimensional control, the tolerance of each product is controlled within ±0.1mm, and the specifications are completely consistent, ensuring the interchangeability of products in long-term use.
This drop forged right angle scaffolding coupler is made of high-quality Q235 carbon structural steel, with a standard size that fits 48.3mm international universal scaffolding steel pipes. The single product weight ranges from 1.0kg to 1.2kg, and can be customized according to customer requirements. The surface treatment adopts hot-dip galvanized, electro-galvanized or painted options, among which the hot-dip galvanized zinc layer thickness is ≥85μm, which meets the highest anti-rust requirements for outdoor long-term use. The product has passed the professional load test, with a minimum breaking load of ≥25KN, and the steel pipe slip is ≤0.5mm under the specified locking torque, which fully complies with EN74 and BS1139 standards.
