SZ dynamic anchor: heavy-duty shear and tension

SZ is a heavy-duty arrow anchor for shear and tension, designed for dynamic loading. It carries European ETA1 approval for cracked and non-cracked concrete and seismic approval C1-C2, and is additionally covered by a VdS approval for sprinkler and fire-protection systems.

Available in three heads

The series is supplied in three heads — SLPC, SLPT and SLPE — so the head can be matched to the application without giving up any of the approvals. This lets the same approved anchor body serve a wide range of fixings while keeping a single, consistent design basis.

Approvals and standards

European ETA1: approved for both cracked and non-cracked concrete, the most demanding category for post-installed anchors.
Seismic C1-C2: qualified for seismic design categories C1 and C2 for use in earthquake-resistant structures.
Dynamic loading: tested for loads that vary over time — vibration and cyclic loading — not only static loads.
Fire rating: rated for fire-exposure conditions.
VdS sprinkler approval: recognised for fixing sprinkler and fire-protection pipework.

Typical applications

Structural steel and heavy fixings subject to shear and tension
Machinery bases and equipment exposed to vibration and cyclic loads
Sprinkler and fire-protection pipe supports (VdS)
Seismic-rated connections in concrete structures

Frequently asked questions

What is the difference between SZ and SLPT?

SZ carries a broader range of approvals — impact loading and fibre-reinforced concrete. SLPT carries ETA1 and seismic approval C1-C2, and is available in a range of heads (SLPC / SLPT / SLPE).

What is the difference between a dynamic anchor and a standard arrow anchor?

A dynamic anchor is tested and approved for loads that vary over time — vibration, cyclic loading and earthquakes. MTP-X is a standard arrow anchor for cracked concrete; SLPT and SZ are specifically intended for heavy dynamic loads.

Which heads are available for the SZ anchor?

The SZ series is supplied in three heads — SLPC, SLPT and SLPE — so the head can be matched to the application while keeping the same European ETA1 and seismic C1-C2 approvals.

Is the SZ anchor suitable for sprinkler systems?

Yes. In addition to the European ETA1 approval, SZ carries a VdS approval, which specifically covers the fixing of sprinkler and fire-protection installations.
