Advantages of the product

Superior Holding Strength in Concrete with Our Expansion Bolts

Our expansion bolts are engineered to provide exceptional holding power in solid base materials like concrete, brick, and stone. The expansion mechanism, often a cone-shaped plug drawn into a sleeve, creates high friction and mechanical interlock against the walls of the drilled hole. This design effectively distributes the load, offering high resistance to pull-out forces and vibration. They are ideal for anchoring heavy machinery, structural elements, and safety equipment, ensuring a secure and permanent fixation.

Versatile Expansion Bolt Range for Various Substrates and Loads

We offer a comprehensive selection of expansion bolts, including wedge anchors, sleeve anchors, and drop-in anchors, each suited for different load conditions and installation methods. This variety allows for the appropriate selection based on the specific substrate, required load capacity, and whether the installation is overhead or in the floor. Our technical data sheets provide clear load ratings to assist engineers and contractors in making the correct choice for their project's safety and performance requirements.

Corrosion-Resistant Expansion Bolts for Long-Term Durability

To ensure longevity, our expansion bolts are available in materials with high corrosion resistance. Options include hot-dip galvanized carbon steel and austenitic stainless steel (A4/316), which are suitable for humid, outdoor, and chemically aggressive environments. This focus on durability prevents anchor failure due to rust, which is critical for the long-term safety and integrity of the anchored structure, such as in bridges, facades, and industrial plants.

Metal expansion bolts are essential components in various construction and industrial applications, providing secure fastening solutions that can withstand significant loads. These bolts work by expanding within a pre-drilled hole when a nut is tightened, creating a strong hold that is resistant to pull-out forces. At Handan Layson Fastener Co., Ltd., we manufacture a comprehensive range of metal expansion bolts suitable for different materials, including concrete, brick, and masonry. Our products are engineered for maximum strength and durability, making them ideal for both indoor and outdoor use.

The versatility of our metal expansion bolts allows them to be used in a wide array of applications, from securing structural elements in buildings to anchoring equipment in industrial settings. We pride ourselves on our ability to meet the specific needs of our clients, offering a variety of sizes and configurations to ensure optimal performance. Furthermore, our commitment to quality means that our products undergo rigorous testing to ensure they meet international standards. Choose Handan Layson Fastener Co., Ltd. for your metal expansion bolt needs and experience unparalleled quality and service.

Common problem

How does an expansion bolt work for secure fastening?

An expansion bolt works by inserting it into a pre-drilled hole. As the nut is tightened, it pulls the bolt body upward, causing an expansion sleeve to compress and expand outward against the walls of the hole (typically in concrete). This creates a powerful frictional and mechanical interlock, providing extremely high pull-out strength for a secure hold.
Correct hole size is critical because it allows the expansion sleeve to deform properly and exert uniform pressure against the hole walls. A hole that is too large will prevent adequate expansion, leading to a weak hold. A hole that is too small can prevent proper installation or cause inadequate expansion. We provide precise diameter and depth specifications with our bolts.
Our QC for expansion bolts involves testing the expansion mechanism, material hardness, and ultimate load capacity. We simulate real-world conditions to ensure the sleeve expands consistently and the bolt achieves its rated holding power. This rigorous process guarantees that every bolt provides a safe and reliable anchorage, upholding our reputation for quality.
