Internally Forced Expansion Anchor Manufacturer - Heavy-Duty Internally Forced Anchor Seismic Design Hot-Dip Galvanized - Customization Supported
Product Description: Internally forced expansion anchor bolts are a common and efficient anchoring fastener consisting of a bolt, expansion sleeve, and nut, generating tightening force through internal expansion. Internally forced expansion anchors are certified to national standards (GB/T 22795) and European standards (ETAG), and are indispensable in load-bearing anchoring applications such as building curtain walls, equipment foundations, and steel structure installations. They provide strong seismic and impact-resistant anchoring. To enhance the load-bearing capacity and durability of the anchors, we can perform hot-dip galvanizing to improve their corrosion resistance, or use alloy steel materials and optimized expansion cone angle designs, which can significantly improve the tensile strength and fatigue resistance of the anchors.
Nanning Aozhan supplies a wide variety of internally forced expansion anchors in complete specifications, with guaranteed quality and customization support. Contact us now!
