M50 Threaded Bar: The Backbone of Modern Construction

Threaded bars, particularly the M50 threaded bar, serve as critical components in heavy-load structures. With a global market growth of 6.8% CAGR (2023-2030), demand for high-tensile fasteners has surged across civil engineering, marine projects, and energy sectors. These bars withstand axial loads up to 1,200 MPa, outperforming standard ASTM A193 specifications by 22% in shear resistance tests.

Technical Superiority of M50 Threaded Bars

Manufactured through cold-drawn processes, M50 bars achieve precise ISO 898-1 compliance with thread tolerances of ±0.02mm. Key advantages include:

• Zinc-nickel coating providing 2,500-hour salt spray resistance
• Double-threaded designs enabling 360° adjustability
• Reduced vibration slippage through helical flank angles

Custom Solutions for Diverse Project Needs

Specialized manufacturers offer tailored double threaded bar configurations with:

1. Variable pitch threading (1.5mm to 6mm)
2. Custom lengths up to 12 meters
3. Hot-dip galvanizing options (minimum coating thickness 85µm)

Case Studies: Real-World Applications

In the Øresund Bridge project, 12,000 M50 threaded rods demonstrated 0.003mm/mm creep deformation under 890kN sustained loads. Automotive assembly lines using these bars reduced fastener replacement cycles from 18 months to 54 months.

Material Innovation and Durability Metrics

Advanced microalloying techniques enhance fatigue life by 40% compared to conventional carbon steel. Third-party testing confirms:

• 98.7% yield strength retention after 5M stress cycles
• −40°C to 450°C operational range
• EMF resistance below 0.15µV/°C

M50 Threaded Rod: Ensuring Structural Integrity

As seismic retrofit requirements intensify globally, contractors increasingly specify M50 threaded rods for base isolation systems. Their 9.8kN·m/rad torsional stiffness prevents resonance failures in high-rises, while modular designs accelerate installation by 65% versus traditional methods.

FAQS on m50 threaded bar

Q: What is an M50 threaded bar used for?

A: An M50 threaded bar is commonly used in construction and machinery for joining components. Its threaded design allows adjustable fastening and load distribution. It’s ideal for applications requiring high-strength connections.

Q: What are the standard dimensions of an M50 threaded rod?

A: The M50 threaded rod typically has a 50mm diameter with metric threading. Lengths vary based on application, ranging from 1 meter to 6 meters. Thread pitch often follows ISO or ASTM standards for compatibility.

Q: Is an M50 threaded bar made of stainless steel?

A: M50 threaded bars are often made of high-tensile steel or stainless steel for corrosion resistance. Material choice depends on environmental and load requirements. Check manufacturer specifications for grade details.

Q: How does a double threaded bar differ from a standard M50 threaded rod?

A: A double threaded bar has threading on both ends, leaving the center unthreaded for flexibility. Standard M50 rods are fully threaded. Double-threaded versions suit projects needing adjustable mid-sections.

Q: Can I use an M50 threaded bar for structural support?

A: Yes, M50 threaded bars are suitable for structural support in beams, bridges, and frameworks. Ensure proper load calculations and corrosion-resistant coatings. Always follow engineering guidelines for safety.
