1. Long life. The life expectancy of galvanized coatings on typical structural members is far in excess of 50 years in most rural environments, and 20 to 25 years plus, even in severe urban and coastal exposure. 2. A full protective coating can be applied in minutes; The galvanizing process is not dependent on weather conditions 3. Lowest first cost. Galvanizing is lower in first cost than many other commonly specified protective coatings for steel. (The application cost of labour intensive coatings such as painting has risen far more than the cost of factory operations such as galvanizing.)

1. Toughest coating. A galvanized coating has a unique metallurgical structure which gives outstanding resistance to mechanical damage in transport, erection and service. 2. Reliability. Galvanizing is carried out to Australian / New Zealand Standard 4680, and standard, minimum coating thicknesses are applied. Coating life and performance are reliable and predictable. 3. Less maintenance/Lowest long term cost. Even in cases where the initial cost of galvanizing is higher than alternative coatings, galvanizing is almost invariably cheapest in the long term (because it lasts longer and needs less maintenance). And, maintenance causes problems and adds to costs when structures are located in remote areas, and when plant shutdown or disruption to production is involved.

Manual operation aluminum roller shutter could be open and close even without power. In this case, you don't have to worry about electricity failure. It's very popular in Africa market based on the power supply shortage in Africa. Security / burglarproof. our aluminum rolling shutter doors are made of 6063 aluminum which meet the industry standard requirement, so once you have chosen an aluminum roller shutter door, it means that you have chosen security and burglarproof.
