Engineered Precision
& Bonding Excellence

Defining the gold standard in high-strength chemical anchoring systems.

As a global leader in the fastener manufacturing sector, we specialize in the production of chemical anchor fastener solutions. Our products occupy a dominant industry position, ensuring that structural connections in large-scale infrastructure projects remain immovable under extreme seismic and static loads.

Our technical superiority is rooted in advanced resin polymerization and metallurgical precision. By integrating chemical anchor fastener technology with high-tensile alloy studs, we achieve superior bond strength and corrosion resistance that far exceeds standard mechanical expansion anchors.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

01

What is the primary advantage of a chemical anchor fastener over mechanical ones?

Chemical anchors create a bond with the concrete that doesn't introduce expansion stress, allowing for closer spacing and higher loads in edge-distance critical areas.

02

How do I choose between Epoxy and Vinylester resins?

Epoxy is ideal for high-strength, long-term structural bonding and low shrinkage. Vinylester offers faster curing times and superior resistance to corrosive chemicals.

03

What is the importance of hole cleaning in chemical anchoring?

Dust prevents the resin from adhering to the concrete walls. Proper blowing and brushing are mandatory to ensure the rated load capacity is achieved.

04

Can chemical anchors be used in wet concrete?

Yes, we offer specialized resins specifically designed for water-saturated holes and underwater applications without compromising bond strength.

05

What is the typical shelf life of the chemical resin?

Typically 12 to 24 months when stored in a cool, dry place away from direct sunlight. Always check the batch date on the cartridge.

06

Do you provide calculation reports for load-bearing analysis?

Yes, our technical team provides detailed load-bearing calculation reports based on the specific concrete grade and anchor geometry used in your project.
