Different concrete anchors serve different load ranges. Understanding load classification helps buyers select the right anchor type and avoid over-design or insufficient safety margin.
Light load applications include small decorative brackets, cable trays. Drop-in anchors and small expansion anchors are enough. Medium load for window frames, ceiling hangers, you can use self cutting screws or standard expansion anchors.
Heavy load scenarios like railings, machine bases require wedge anchors. It is worth noting that the nominal load data on catalog is tested under standard solid concrete. Actual site load will decrease if concrete is cracked or low strength.
Always reserve safety factor when designing anchor connections.
