Typically, galvanized iron sheets are available in various thicknesses measured in gauges. The most common standards range from 18 gauge (approximately 1.2 mm) to 26 gauge (approximately 0.5 mm). Thicker sheets, like 18 or 20 gauge, are commonly used in applications requiring structural strength, such as construction and industrial settings. In contrast, thinner sheets are often applied in manufacturing and household fixtures where weight and flexibility are crucial.
Galvanization involves coating iron or steel with zinc to prevent rusting. While this treatment extends the life of pipes, it also alters their surface texture. The roughness created by the galvanization process can increase the friction factor compared to smooth-walled pipes. This increase implies greater energy requirements for pumping fluids through galvanized pipes, particularly in systems that rely on water or other low-viscosity fluids.

Different applications necessitate different thicknesses of corrugated steel sheets. For roofing applications, sheets must be engineered to withstand various environmental factors, including wind, rain, and snow. Generally, a thickness of at least 0.5 mm (approximately 26 gauge) is recommended for residential roofing to ensure durability and longevity. In commercial settings, thicker sheets (0.7 mm or 24 gauge and above) may be favored for added strength and resistance against heavy loads.

However, it is crucial to note that the practice of head spearing has been criticized and condemned by many for its violent nature
. With the advent of colonialism and the spread of Christianity, headhunting rituals began to decline, eventually being eradicated in most parts of the world due to the influence of Western moral values and laws.Once your iron fence is free from rust, dirt, and debris, you can paint it to add an extra barrier between the iron and the elements, further preventing oxidation. Painting your fence can also enhance its beauty, and of course, you can choose any color and style you think suits it best. After the paint has dried, it’s also a great idea to apply a coat of all-weather sealant to really ensure it is protected from weathering.
