What kind of burglar protection devices should be used in rolling grilles?
Considering the type of application, a sufficient protective device is a bolt lock fixed in the bottom curtain strip on the inside of the grille and operated from both sides. The lock makes it impossible to lift the grille from the outside, when locked.
Both my own safety and that of my workers is very important to me. What grille should I opt for?The best rolling grille types are equipped with several independent protection systems, including:
- spring break protection,
- photocell sensors,
- protection against shaft rolling,
- emergency brake,
- optical/pneumatic edge protection (against crushing),
- lock micro-switch.
Customers frequently choose grilles in a "natural" colour of anodized aluminium which blends in well with almost every kind of surroundings. It is a good opportunity if the manufacturer offers grilles in any RAL colour. In this case, it is easy to match the colour of the grille to your individual preferences.
I'm opening an art gallery. I know I have to protect it well, but I'm worried that a rolling grille could make the whole building look ugly. What things should I pay attention to?You will certainly find a suitable product. Esteemed manufacturers offer "robust" steel structures that look good in classic-styled buildings and "light" aluminium grilles that blend in well with modern architecture. (Naturally, both types offer effective protection against burglary). It is also possible to combine grilles with full metal sections to obtain an original solution that emphasizes the style of the building.
What are the main benefits offered by rolling grilles?Selecting a rolling grille from a good manufacturer, you get the following benefits:
- Easy and safe opening and closing,
- High resistance to damage and being pulled out,
- Convenient operation (if you select an automatic control option),
- Smooth and fault-free use.
Rolling grilles are usually used in shopping centres to protect various types of shops, service outlets and other facilities. In addition to performing the function of doors, grilles protect shop windows. Being relatively cheap and available in a broad selection of options, they are growing in popularity on the Polish market.
What elements are important for the durability of rolling grilles?The most important factors affecting durability are materials used for production. Highly durable grilles must be made of top-quality galvanized steel and aluminium. Also, the structure must be suited to the grille's intended application. Grille opening mechanisms must be capable of withstanding several thousand opening and closing cycles.
I'm thinking of having a rolling grille fixed in my warehouse. The warehouse entry is quite large (5 m wide and 3 m high). What grille should I pick?If the entry is so large, we definitely recommend a grille made of profiled sinusoidal steel tubes joined by means of steel clamps. It has excellent resistance and is reasonably priced.
