What is the minimum diameter for truss type cross wires recommended for quality?

The minimum diameter for truss type cross wires that is recommended for quality is 1/8 inch. This size is often chosen because it provides a good balance between strength and flexibility, which is essential for truss construction. Thinner wires may not provide the necessary support or may fail under load, while excessively thick wires can add unnecessary weight and complicate the truss design. By selecting a 1/8 inch diameter, builders ensure that the cross wires can adequately contribute to the structural integrity of the truss system while maintaining practicality in terms of material usage and overall performance.
