Heavy Duty Plasterboard Fixings

From their conception, we’ve known that the GeeFix fixings would outperform our competitors because of their large, flat, solid load bearing back-plate. Many popular fixings have a hollow channel-shaped back-plate, the sharp edges of which cut into the plasterboard. Over time, these incisions diminish the plasterboard’s integrity, causing the fixing to become loose and ultimately fail. In an industry saturated with superlative claims we knew that we needed some hard data to hang our hat on (excuse the pun), so we arranged for the GeeFix fixings to be independently strength tested. The graphic below shows how GeeFix performed in strength tests, conducted on 15mm plasterboard: (Click to enlarge graphic)

Weights and Loads

Heavy duty plasterboard fixings have to support three types of load forces: Cantilever loads (suspended away from the wall), shear loads (pulling down against the vertical surface of a wall) and tensile loads (pulling away from a wall or ceiling). Most manufacturers typically highlight the shear strength of their fixing, emboldening their claims that their product is the strongest. A plasterboard fixing that has a high shear strength, for example, may not be suitable for mounting a large cantilever load, such as a 32 inch flat screen television on an articulating wall mount.

So, in order to select a fixing that’s right for your installation, you need to know how the fixing performs in all three of the above categories.
