Base metal thickness (Gauge) of roofing sheets

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. You will note that as the gauge number increases, the sheet’s thickness decreases. 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 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.

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.
