Product Description

Crab Type Steel Tube Scaffolding - Heavy-Duty Modular Support System 

Shandong Xingrui Building Materials Co., Ltd. manufactures the 60-series Crab Type Steel Tube Scaffolding with uniform tube wall thickness engineered from Q235 premium steel. Our system features vertical standards of 60.3mm outer diameter, equipped with two-way diagonal tie bars that deliver superior frame stability for basement and factory large-span formwork support. With strict ISO 9001, ISO 14001, and ISO 45001 management system certifications, our product ensures anti-overturning and deformation-resistant performance. The reusable system is made to order and backed by technical support on call, serving construction projects across more than 100 countries since 2007.

What Makes Crab Type Steel Tube Scaffolding Different?

This high-performance modular support system features a unique crab-claw socket connection mechanism. Unlike traditional tube-and-coupler systems, it utilizes prefabricated vertical standards with fixed sockets and horizontal ledgers with wedge-shaped heads.

The design locks securely into place with hammer-and-wedge assembly. You gain maximum load-bearing efficiency at every joint without the risk of loose fitting adjustments.

Our system solves critical industry pain points. It reduces labor costs, accelerates erection speeds, and minimizes human error in complex high-rise and heavy-load projects.

Core Technical Properties You Can Rely On

Your projects demand durability and high load-bearing capacity. Our system delivers both through advanced material selection and engineering design.

The outer diameter of 60.3mm with wall thickness ranging from 3.0mm to 3.25mm provides exceptional structural integrity. Hot-Dip Galvanization with coating thickness of ≥80μm offers superior resistance to oxidation and chemical corrosion.

The crab node offers high torsional stiffness. You can simultaneously connect up to four horizontal or diagonal members at each junction point.

Our system complies with international quality standards including EN 12810-1 and AS/NZS 1576. It maintains a safety factor of at least 2:1 for vertical loads and exceptional performance under wind-induced lateral forces.

Core Technical Properties You Can Rely On

Industrial Applications Where Performance Matters

Bridge and Viaduct Engineering: Our heavy-duty shoring system supports cast-in-place concrete box girders. The high single-post load capacity handles immense pressure during critical pours.

Industrial Plant Maintenance: Refineries and power plants benefit from rapid erection around complex boiler structures and spherical tanks. The modularity works within constrained spaces while maintaining paramount safety standards.

High-Rise Construction: For skyscrapers exceeding 100 meters, the system provides stable work platforms. Integrated internal ladders and toe-boards maintain structural integrity against high-altitude wind loads while facilitating efficient vertical material transport.

Factory and Basement Support: The 60-series eight-hole disc heavy support system equipped with two-way diagonal tie bars allows larger unsupported spans. You reduce upright consumption and material investment with prominent economic benefits.

Industrial Applications Where Performance Matters

Quality Control That Protects Your Investment

Our manufacturing process at the 79,800 square meter facility includes rigorous inspection protocols for Crab Type Steel Tube Scaffolding. With 12 welding robots and 6 automatic welding lines, consistency is built into every component.

Spectral analysis confirms carbon and manganese content of steel. Ultrasonic and Magnetic Particle Inspection verify crab socket welds to prevent shear failure under load.

Dimensional tolerance stays within ±0.5mm for seamless interlocking. Destructive and non-destructive compression tests validate compliance with rated capacities.

Salt spray testing confirms the longevity of the galvanized finish. This is essential for coastal or high-humidity project sites where durability matters most.

Why Professional Contractors Choose Our System

Assembly Speed Advantage: You complete erection 3 to 5 times faster than traditional coupler systems. This significantly reduces site labor costs and project timelines.

Enhanced Stability: The wedge-lock mechanism provides higher torsional rigidity compared to top-cup screw mechanisms. Visual inspection of the locking state is faster and more reliable.

Standard Compatibility: Horizontal ledgers work within standard 48.3mm scaffolding dimensions. You can integrate with traditional steel planks and ladders without compatibility issues.

Long-Term Value: With proper maintenance, the system delivers over 15 years of service life. Even in repetitive rental cycles, the Hot-Dip Galvanization maintains structural integrity.

FAQ

Q:How does the system compare to Cuplock scaffolding?

A:While both are modular, our wedge-lock mechanism provides higher torsional rigidity. You get faster visual inspection of the locking state compared to the top-cup screw mechanism.

Q:Does installation require specialized tools?

A:No, the system uses hammer-and-wedge assembly. You only need a basic scaffolding hammer to secure connections, minimizing the need for complex power tools on-site.

Q:What is the expected service life?

A:With proper Hot-Dip Galvanization, you can expect over 15 years with minimal maintenance. The system performs reliably even in repetitive rental cycles.

Q:Is it compatible with standard tubes?

A:Yes, the horizontal ledgers work with standard 48.3mm tubes. You can integrate with traditional steel planks and ladders seamlessly.

Q:What safety standards does it meet?

A:Our product complies with EN 12810-1 and AS/NZS 1576 international standards. It maintains a safety factor of at least 2:1 for vertical loads.
