(m50 threaded bar)
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.
Manufactured through cold-drawn processes, M50 bars achieve precise ISO 898-1 compliance with thread tolerances of ±0.02mm. Key advantages include:
Feature | Manufacturer X | Manufacturer Y | Manufacturer Z |
---|---|---|---|
Material Grade | ASTM A574 | DIN 975 | ISO 4032 |
Tensile Strength | 1,150 MPa | 1,040 MPa | 1,220 MPa |
Corrosion Resistance | Class 8.8 | Class 10.9 | Class 12.9 |
Price/meter (USD) | $18.50 | $22.80 | $27.40 |
Specialized manufacturers offer tailored double threaded bar configurations with:
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.
Advanced microalloying techniques enhance fatigue life by 40% compared to conventional carbon steel. Third-party testing confirms:
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.

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.
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.
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.
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.
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.
