The fixing condition
Most construction fixing failures come from the wrong anchor for the base material, not from a defective anchor. A wedge anchor in cracked concrete, a sleeve anchor carrying a structural load, or a hole drilled to the wrong depth will all underperform regardless of the product quality.
We supply the common mechanical anchor families — wedge, sleeve, drop-in and bolt-type — so a project can be specified with the correct anchor for each condition. We do not publish load tables that have not been verified; ask for the documentation required by the project and it will be confirmed before quotation.
What to prepare before an enquiry
Base material
Concrete, brick or block determines the anchor family. Cracked concrete may require a specific approved anchor.
Load case
Tension, shear and combined loading each need a suitable anchor and embedment depth.
Edge and spacing
Close edges and reduced anchor spacing lower capacity. The project engineer should check the layout.
