Product Description

Metal anchor body anchors include round steel anchors (solid anchors), threaded steel anchors, tubular anchors (hollow anchors) and flexible anchors. Low-strength anchors mainly refer to round steel anchors with a yield strength of less than 300Mpa; medium-strength anchors have a yield strength between 300 and 400MPa and are usually made of construction threaded steel (20MnSi); high-strength anchors have a yield strength between 400 and 600MPa; strong-strength anchors have a yield strength of no less than 600MPa and a breaking load of more than 300kN.

What types of metal anchors are available?
We provide a wide range of metal anchor bodies including round steel (solid), threaded steel, tubular (hollow), and flexible anchors to suit various construction needs.
How is the strength of the anchors classified?
Anchors are classified by yield strength: Low-strength (<300Mpa), Medium-strength (300-400MPa), High-strength (400-600MPa), and Strong-strength (≥600MPa) with breaking loads exceeding 300kN.
How is the quality of the metal fabrications ensured?
Quality is ensured through a rigorous control process, including multiple inspections at every production stage and advanced testing equipment to verify structural integrity and durability.
Can you handle large-scale structural projects?
Yes, the facility is equipped with state-of-the-art machinery capable of handling complex projects, from commercial structural steel frames to intricate custom installations.
Are the anchors resistant to shear and high torque?
Yes, our hollow anchors are tested for high performance, with shear strengths up to 150 MPa and torque capacities reaching up to 200 Nm depending on the specific model.
Do you stay updated with industry innovations?
We constantly invest in research and development and attend major trade shows to incorporate the latest metalworking technologies and design trends into our product line.
