China Suppliers British Standard Forged Couplers - Durable, High Strength, and Customizable Factory Products
Core Advantages
1. Excellent Anti-slip Performance (Wide Fitting Area)
The fastener adopts a wide surface fitting design with steel tubes achieving full surface tight occlusion. It overcomes point/line contact defects of old style fasteners, eliminates slipping risks and improves overall mechanical performance and safety capacity of scaffolding.
2. Strong Corrosion Resistance (Dual Anti-rust Treatment)
Treated with passivation and hot dip galvanizing, the uniform and compact coating greatly boosts rust and salt spray resistance, with a service life far longer than ordinary fasteners.
3. Fastener Bolt (8.8 High Strength Grade)
Made of 35# high quality raw materials via quenching process, bolts reach 8.8 grade standard with optimal bending resistance, tensile resistance, fatigue resistance and wear resistance.
4. Anti-drop Bolt (Customized Technology)
The anti-drop structure of bolts can be customized according to customer requirements, which effectively prevents the loss and falling off of fastener screws, meeting the high-standard construction requirements of overseas projects.
Technical Specifications & Standards
1. Material & Process
The coupler main body is forged from high-quality Q235B carbon round steel, treated with passivation and hot-dip galvanizing dual anti-rust process. The zinc coating is uniform and compact, featuring strong adhesion, excellent wear resistance, impact resistance, crack resistance and weather resistance.
2. Compliance Standards
Our products strictly comply with national standard GB15831-2006, European standard EN74 and British standard BS1139. The British standard couplers have passed BETC special appraisal and CQCS national quality certification, also obtained CE certification.
3. Specifications & Customization
We supply right-angle, swivel, sleeve and other mainstream types of scaffolding couplers. Custom anti-drop bolt structure is available to prevent screw loss and falling off, fully meeting high-standard construction demands of overseas projects.
4. Load-bearing & Safety Performance
Adopting integrated forging molding, our couplers have superior tensile strength and toughness. Wide-surface fitting design achieves full contact with steel tubes to avoid slipping risks, greatly improving overall structural stability and safe load capacity of scaffolding systems.
Product Types & Application
1. Swivel Coupler
Enables diagonal connection at any angle. Ideal for building cross bracing, diagonal tension rods and special-shaped scaffolding.
2. Right Angle Coupler
For 90° vertical connection of steel tubes, fixing uprights and ledgers to build the main frame of scaffolding.
3. Connect the fasteners
For steel pipe extension and jointing. Connect pipe ends to lengthen uprights and ledgers.
4. Fixing plate fastener
Secure scaffolding to building structures, floor slabs and steel plates for ties and supports.
5. Limpet Coupler
Connect steel pipes to steel plates and components; fix scaffolding to walls and embedded parts.
6. Cantilever beam fastener
Connect steel beams / Ibeams with steel pipes. Specially used for cantilever scaffolding and load-bearing frames.
Industry Applications
1. Building Construction
Suitable for high-rise buildings, residential communities, commercial buildings and other civil construction scaffolding projects.
2. Bridge & Infrastructure
Widely used in bridge erection, viaduct, municipal road and tunnel construction support projects.
3. Petrochemical & Power Engineering
Applied for factory workshop, power station, chemical plant and industrial equipment maintenance scaffolding.
4. Overseas Engineering Projects
Comply with international British, European standards, perfectly match overseas high-standard construction bidding projects.
Process Advantages and Material Selection Guidelines
Advanced high-speed rolling and controlled cooling technologies ensure dimensional precision (±0.1 mm) and microstructural homogeneity, supporting downstream processes like drawing and heat treatment. Material selection must comply with industry standards (ASTM, GB/T, JIS), prioritizing carbon content, elongation, and surface defect control.
