Questions about security grills
How can I recognise security grills?
All grills that we provide to our customers fulfil the material and structural requirements of insurance companies.
Is it possible to install security grills from the inside?
That is actually one of the best ways to secure your property. A burglar must first break the glass, thus setting off an alarm or at lease making noise, and then he is faced with the main barrier.
What kind of surface treatment do the grills have?
It is possible to deliver grills in primer or in synthetic or acrylic paint. However, the most common surface treatment is komaxit powder coating. Of course, it is also possible to provide galvanised grills.
Can you adjust the colour shade of grills to match the façade or window frames?
Of course. It is possible to choose the right colour shade from the full scale according to the RAL sample book.
How long are the delivery times?
The standard period for delivery is three weeks; the exact date is always set in the contract.
Do your grills have security certificates?
Yes, all types of our grills are manufactured with respect to increased building security and have variants certified in security classes 2 and 3.
What kind of grill models do you have?
In the case of fixed grills, we offer 25 basic models with the possibility of manufacturing almost any atypical design according to the customer’s requirements. Rolling shutters are also offered in a full range of variants. The design of folding grills is determined by their construction.
Do you provide installation outside of Prague?
Our network of branches covers the entire Czech Republic.
Is it possible to order grills without installation?
Yes, though anchoring and installation play an essential role in the resulting security. Therefore, we recommend a thorough consultation with our technician.
Can grills be unlocked only from the inside?
Locking is possible from the inside, outside or both sides.
What kind of materials are the grills made of?
All grills are made of high-quality steel; some types of rolling shutters are made of aluminium.
Do you provide grill maintenance service?
Of course we provide warranty and post-warranty service.
What are the maximum dimensions of grills?
The recommended maximum dimensions of rolling shutters are 12 m wide and 6 m high; in the case of folding and fixed grills, the dimensions are 3.5 m high and 6 m wide. Grills with larger dimensions can be manufactured, though only after thorough consideration of the individual technical conditions.
What sort of structural interventions are necessary during installation?
Only minimal intervention is required, as the installation work is performed without cutting or demolition. Anchoring usually requires bored holes, which are then covered by guide rails or the grill’s frame. In some cases, it is necessary to use a supporting steel structure or welding in the structural assembly.
How are the grills anchored?
High-quality anchoring is an essential element of security grills. This mostly involves steel anchors, screws with security heads or so-called chemical anchors.
How are rolling shutters controlled?
Rolling shutters with smaller dimensions are controlled manually – lifting is assisted by steel springs that bear the weight of the shutter. Larger rolling shutters have motorised operation with the possibility of your choice of control units ranging from push-buttons and key switches to keypads, magnetic readers and remote control.
How can shutters be opened if the power is out?
Rolling shutters have an emergency control system that enables mechanical opening and closing of the shutters in the event of a power outage.
How wide is a folded grill?
A one-metre-wide grill folds to 18 cm. After folding, the grill wing can be tilted 90 degrees and the tilted wing is easily hidden behind the window frame.
I already have several grills on my home. Can you make the same kind?
If the element of security can be preserved, we can manufacture any design for you.
