Protecting Industrial Roofing Investment
Bangladesh's high humidity, heavy monsoon rains, and coastal salinity pose continuous corrosion threats to industrial roofs. Proper design material selection and simple annual maintenance can double your roof's service life to 30+ years.
1. Choose 55% Aluzinc AZ150 Substrate
Always specify minimum AZ150 coating (150 g/m² aluminum-zinc alloy) with Super Durable Polyester paint rather than basic galvanized iron sheets.
2. Inspect & Clean Eave Gutters Bi-Annually
Debris accumulation in gutters retains moisture and acidic rain sludge, accelerating localized rust. Clear gutters before the monsoon season starts.
3. Use Only Class 3 EPDM Bonded Fasteners
Inferior local screws rust within 2 years, breaking the rubber seal and causing roof leaks. Billal Steel uses Class 3 coated self-drilling screws with genuine EPDM washers.
