Mechanical Anchors
Expansion anchors for concrete and masonry
Wedge anchor is a versatile mechanical fastener engineered for anchoring into concrete (≥C20) and natural hard stone. Manufactured from Grade 5.8 / 8.8 alloy steel, A2/A4 stainless steel (50/70/80 grades), or TA2 titanium alloy, it offers a combination of high tensile capacity, ease of installation, and durable expansion performance.
Applications
- Suitable for tension zone or cracked concrete (≥C20) and natural stone substrates
- Anchoring of equipment, channel steel, rails, and support brackets
- Fastening under impact or dynamic loads
- Structural connections for beams and columns
- Exterior wall, pipeline, and general-purpose fastening
- Ideal for medium-duty and light structural applications
