A tin roof is one of the greatest indicators of prosperity in the developing world – Chelsea Clinton

Mabati Gauge refers to the thickness of roofing sheets and is measured in millimeters (mm) using a micrometer screw gauge. The relationship between Gauge and thickness is defined in the East Africa standard for steel sheets and is tabulated below.

  • Gauge 32     0.20mm  ±12%
  • Gauge 30     0.25mm  ±10%
  • Gauge 28     0.32mm  ±10%
  • Gauge 26     0.40mm  ±10%
  • Gauge 24     0.50mm  ±10%

You will note that as the gauge number decreases, the sheet’s thickness increases. There is need to optimize and use the right Mabati size to avoid exerting unnecessary weight on the building structure.

Gauges 28 and 30 are recommended for residential houses. Gauge 32 is too light and tends to wobble when the fundi steps over them during installation. Gauge 32 is widely used for fencing/hoarding. Gauges 28, 26 and 24 are more stronger, durable and suitable for industrial and commercial structures like Go-downs/Warehouses, metro rails, supermarkets/Malls, aircraft hangars, sports stadiums, auditoriums, churches, schools, hospitals, universities and infrastructural projects. Heavy gauges like 26 and 24 are good for walling/cladding.

Gauges 21, 20, 19 and 18 are good for decking sheets and can be obtained from companies like Zenith Steel Fabricators Limited. Gauge 18 is 1mm thick, Gauge 16 is 1.2mm thick, and so on.

A roof is one of the most essential parts of building. A good roof adds unlimited aesthetic value to the building. It is therefore important to get it right in terms of design, color, profile, Gauge/Thickness and the workmanship. Ensure you source your materials from a reliable supplier as Mabati Yetu Factory.
