Frequently Asked Questions — APL Apollo Roofing Sheets

What thickness is recommended for residential roofing with APL Apollo?

For residential roofing (homes, sheds, small warehouses), the 0.47 mm thickness is the most widely recommended. It offers a good balance between structural strength and cost. For industrial sheds and larger spans, 0.50 mm or 0.55 mm provides better rigidity and wind resistance.

What zinc coating should I choose — 120 gsm, 180 gsm, or 275 gsm?

Choose zinc coating based on your location's corrosion exposure. 120 gsm suits dry, inland areas with low humidity. 180 gsm is the standard choice for most Indian cities. 275 gsm (also called Z275) is recommended for coastal areas, high-humidity regions, and locations within 20 km of the sea where salt air accelerates corrosion.

What is the standard effective cover width of APL Apollo GC sheets?

APL Apollo GC corrugated sheets have an overall width of 1000 mm and an effective cover (net coverage after side lap) of 838 mm per sheet. When calculating how many sheets cover a given roof width, always use 838 mm, not 1000 mm.

How much does an APL Apollo GC sheet weigh in 0.47 mm thickness?

An APL Apollo GC sheet in 0.47 mm thickness weighs approximately 4.2 kg for the 8 ft (2440 mm) length, 5.2 kg for 10 ft, 6.3 kg for 12 ft, 7.3 kg for 14 ft, and 8.4 kg for the 16 ft length. Refer to the weight chart above for all sizes and thicknesses.
