Concrete Anchors & Expansion Bolts — Sourcing from China

What is the difference between a wedge anchor and a sleeve anchor?

A wedge anchor is a through-bolt anchor driven into a pre-drilled hole in concrete; tightening the nut pulls the cone upward, expanding a wedge clip against the hole walls for a high-strength mechanical grip. A sleeve anchor has an expanding metal sleeve around a threaded stud; it works in a wider range of base materials including brick and block, but typically provides lower pull-out values than a wedge anchor in solid concrete.

Are your anchors ETA or ICC-ES approved?

Standard production anchors from the Yongnian cluster are typically not ETA or ICC-ES approved, as those certifications require expensive per-product testing. For buyers who need ETA-approved anchors for regulated European construction projects, a smaller number of factories can produce to approved designs under OEM arrangement — please specify this requirement at the inquiry stage.

Can anchors be supplied in retail packaging with our brand?

Yes. OEM retail packaging — blister cards, color boxes, private-labeled — is a common arrangement. Minimum order quantities for custom packaging vary by type but usually start from a few thousand pieces per SKU.
