security roller shutter door

1. Automatic protection for damaged areas. Galvanized coatings corrode preferentially to steel, providing cathodic or sacrificial protection to small areas of steel exposed through damage. Unlike organic coatings, small damaged areas need no touch up. 2. Complete protection. Every part of a galvanized article is protected, even recesses, sharp corners and inaccessible areas. No coating applied to a structure or fabrication after completion can provide the same protection. 3. A full protective coating can be applied in minutes; The galvanizing process is not dependent on weather conditions

No coating applied to a structure or fabrication after completion can provide the same protection. 2. A full protective coating can be applied in minutes; The galvanizing process is not dependent on weather conditions 3. 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.

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. 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. 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. Automatic protection for damaged areas. Galvanized coatings corrode preferentially to steel, providing cathodic or sacrificial protection to small areas of steel exposed through damage. Unlike organic coatings, small damaged areas need no touch up. 2. Toughest coating. A galvanized coating has a unique metallurgical structure which gives outstanding resistance to mechanical damage in transport, erection and service. 3. 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.

High security and exceptional strong. As strong as steel roller shutter doors. High impact-resistance. Can withstand the impact of a car driving into it with 30 miles an hour. Scratch-resistant.Won't scratch under normal use. Environmentally friendly. 100% recyclable Fire retardant . Being almost non-flammable, self-extinguishing and low smoke toxicity.

Environmentally friendly. 100% recyclable, it means that you could still recycle it and sell it without polluting the environment. 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. Nice appearance. Any RAL color is available to match your design and surrounding. Aluminum roll up shutter doors always look better than other types of roller shutter doors.

Flexibility: Our manual operation aluminum roller shutter are always easy to push up and down, even a lady can open or close it easily, this is due to our high quality counter spring and spring box system. Security / burglarproof. With locking system on the bottom or middle of curtain, to be locked on both sides of guide rail. Only when you open the lock with keys, can you open the aluminum roller shutter doors. Lightweight. Compared to other type of roller shutter doors, it's lightweight, easy to assembly, transportation and installation.
