Find your perfect fit — measurements, conversion charts and tips.
Selecting the right sizes and specifications is crucial for construction materials. This guide helps you choose appropriate products for your project.
Pipes and Fittings: Plumbing pipes are measured by nominal bore (internal diameter). Common sizes include 15mm (½ inch), 20mm (¾ inch), 25mm (1 inch), and 32mm (1¼ inch). Always verify the pipe schedule (thickness rating) required for your application - residential, commercial, or industrial.
Electrical Wires: Cable sizes are specified by cross-sectional area in square millimeters. For residential applications: 1.5 sq mm for lighting circuits, 2.5 sq mm for 15A power outlets, 4 sq mm for air conditioners and heavy appliances, and 6 sq mm or larger for main distribution. Consult with a licensed electrician for specific requirements.

When in doubt, our staff can help you calculate the right size and quantity based on your material type (wood, concrete, metal) and load requirements.
