Steel Structure
The steel structure is light. Under the same load conditions, the steel structure weighs only one-fifth of the brick structure and half of the concrete structure. Apart from saving architectural space, its basic construction cost can be greatly reduced.
Environmental Friendly, steel is 100% recyclable.
Not restricted by seasons because it is simple and fast to construct.
Durable, the structure can last for 100 years after antiseptic treatment.
Anti-seismic provides resistance to strong wind and earthquake.
Samples are available upon request.
Dimension/size of all the projects are based on case by case.
Tailor to clientâ??s needs.

Product Introduction: Expansion Bolts

Expansion bolts, also known as anchor bolts, are a type of fastener specifically designed for anchoring objects or structures securely to concrete or masonry. These bolts work by expanding within a pre-drilled hole, providing a strong and permanent connection.

The expansion bolt consists of three main parts: the bolt, the expansion sleeve, and the nut. During installation, the bolt is inserted into a pre-drilled hole, along with the expansion sleeve. As the bolt is tightened, the expansion sleeve is forced to expand radially, wedge tightly against the walls of the hole, and anchor the bolt securely in place.

Our expansion bolts are made from high-quality materials, ensuring durability and longevity. They are suitable for use in a wide range of applications, including but not limited to:

Mounting heavy equipment or machinery to concrete floors or walls.
Installing signboards, handrails, or other fixtures to masonry or concrete surfaces.
Securing structural steel members to concrete foundations.
The key benefits of using our expansion bolts include:

Easy Installation: With simple tools and basic DIY skills, you can easily install these bolts.
High Load Capacity: Our expansion bolts are designed to withstand significant tensile and shear loads, ensuring a secure and reliable anchor point.
Versatility: Suitable for use in various materials including concrete, brick, and stone.
Cost-Effective: Provides a permanent and cost-effective solution for anchoring needs.
Whether you're a professional contractor working on a large-scale construction project or a homeowner embarking on a DIY renovation, our expansion bolts are the perfect choice for all your anchoring needs. Order now and experience the difference in quality and performance that our products offer.
