Compared with traditional expansion bolts, what are the advantages of screw heavy duty shield anchor

Screw Heavy Duty Shield Anchor has gradually replaced traditional expansion bolts in modern construction and engineering applications, becoming the first choice for high-load and high-safety anchoring.

More advanced structural design, stronger anchoring force
Screw Heavy Duty Shield Anchor adopts a spiral shield design, which is different from the single expansion sleeve structure of traditional expansion bolts. The spiral shield is installed by rotation to make the shield tightly bite the inner wall of the substrate to achieve multi-point expansion locking. This design greatly increases the anchoring surface area and enhances the mechanical bite force between the anchor bolt and the substrate.
Traditional expansion bolts rely on a single expansion ring to expand and generate friction, which has problems of uneven force and stress concentration, and is prone to cause local rupture of the substrate. The spiral shield disperses the force, avoids local damage, improves the overall anchoring strength and safety margin, and ensures stability under heavy load conditions.

Better load-bearing performance and higher safety factor
Heavy duty spiral shield expansion bolts have higher pull-out resistance and shear resistance, and their load-bearing performance far exceeds that of traditional expansion bolts. Multi-point locking and spiral structure increase the ultimate load of anchor bolts to meet the needs of high-strength engineering.
Through precise mechanical testing and certification, Screw Heavy Duty Shield Anchor has stable and reliable performance in concrete, masonry and other substrates. Its high load-bearing capacity is suitable for steel structure connection, large machinery fixing and heavy equipment installation, significantly improving engineering safety.

Stronger corrosion resistance and wider application environment
Heavy-duty spiral shield expansion bolts are usually made of high-quality carbon steel or stainless steel, supplemented by advanced anti-corrosion processes such as hot-dip galvanizing and electroplating galvanizing. Compared with the ordinary galvanizing treatment of traditional expansion bolts, its corrosion resistance is more excellent and can withstand harsh conditions such as outdoor environment, humidity and salt spray.
The sealing of the shield design effectively blocks moisture from invading the anchor hole and reduces the risk of rust. The improvement of corrosion resistance extends the service life of the anchor bolt, reduces the maintenance frequency and cost, and is particularly suitable for applications in high-corrosion environments such as bridges and seaside facilities.

Simple installation process and higher construction efficiency
The installation process of Screw Heavy Duty Shield Anchor is more convenient and efficient than traditional expansion bolts. Its spiral shield design allows the anchor bolt to expand and lock directly by rotation, without complicated hammering or multi-step operations, reducing the difficulty of construction.
The spiral structure reduces installation resistance, improves the stability and accuracy of installation, and avoids anchor failure caused by improper operation. Construction workers can complete the installation quickly, improving the overall construction progress and quality of the site.

Wider application range, adapting to complex substrate environment
Traditional expansion bolts are mostly used in high-density concrete, and their performance is limited when facing porous or old substrates. Heavy-duty spiral shield expansion bolts can better adapt to masonry structures and composite substrates with many cracks and low strength through multi-point locking and stress dispersion mechanisms.
Its excellent adaptability makes the product perform well in old building reinforcement, structural transformation and various special working conditions, greatly expanding the application field of expansion anchor bolts and meeting diversified engineering needs.

Easy maintenance and long service life
The Screw Heavy Duty Shield Anchor, which has a solid structure and excellent anti-corrosion performance, is not prone to rust, looseness or fatigue damage during use. The maintenance workload is significantly lower than that of traditional expansion bolts, reducing later maintenance costs and safety hazards.
The product design complies with multiple international standards and quality certifications to ensure safety and stability in long-term use. High-quality materials and advanced technology together ensure the durability of the anchor bolt, which is suitable for long-term load applications in critical projects.
