Anchor Bolts

Concrete anchors that fix the bracing and support system to the structure — the load path that transfers seismic forces from pipe, duct and tray back into the building. Undercut, wedge / through and expansion anchors.

Anchor Types

Anchors in Detail

All anchors in Q235B steel to GB/T 700-2006, electro-galvanized as standard, hot-dip galvanized on request. Sizes selected to suit the calculated connection load.

Undercut anchor bolt for concrete high seismic loadZoom
Anchor

Undercut Anchor

  • Mechanical keying into a pre-undercut hole for high, predictable load and seismic performance.
  • Ideal anchor for critical seismic bracing connections in concrete.
  • Q235B steel, electro-galvanized; HDG on request.
Wedge through anchor bolt for concreteZoom
Anchor

Wedge / Through Anchor

  • Expands a sleeve against the hole wall by friction for a reliable concrete fix.
  • Through-fixing design suits support and bracing base plates.
  • Q235B steel, electro-galvanized; HDG on request.
Expansion bolt anchor for concrete buildingsZoom
Anchor

Expansion Anchor (Expansion Bolt)

  • For fixing into concrete structures.
  • Increases the strength and stability of the support system.
  • Q235B steel (GB/T 700-2006), electro-galvanized; HDG on request.
FAQ

Common Questions

What are anchor bolts used for in seismic bracing?
They fix the bracing and support system to the concrete structure, forming the load path that transfers seismic forces from pipe, duct or tray back into the building.
Undercut vs wedge anchor?
An undercut anchor mechanically keys into a pre-undercut hole for high, predictable seismic load; a wedge / through anchor expands a sleeve against the hole wall by friction. Both fix into concrete.
Material and finish?
Q235B carbon steel to GB/T 700-2006, electro-galvanized as standard, hot-dip galvanizing on request.
Which base material?
These anchors are designed for concrete; size and embedment are chosen to suit the calculated load on the connection.
