Frequently Asked Questions
What we have to know before ordering a door?





Are the doors produced with standardized dimensions?
No – each door is produced after an individual customer order. After the customer chooses a door and signs a contract, our technical specialist visits the site and takes down measures according to which the door is produced.
Can I order a door by phone?
Contract signing and concrete order finalization are realized in a showroom chosen by the customer. A phone call might be good for receiving theoretical information and some directions but it is desirable that final choice is made after samples review. Additionally, contract signing is necessary.
Can door decoration casing be installed on a house entrance door?
Door models appropriate for house entrances are designed to be weather-proof. This means that metallic construction and wooden panels are processed by a special technology which protects them against weathering agents. The most vulnerable part of the door is its decorative casing. That is why we recommend finishing of the door with proper plaster or stone when there isn't a sunshade above the door.
Is it possible for a door wooden panel to be replaced in some time?
Yes, this is possible because of the patented disassembling construction, witch allows internal lock mounting and easy and fast design alteration. Wooden panels are not glued to the construction but are rather installed in it through an aluminum edging profile which is Solid's elaboration.
Can a figure be milled on a melamine panel?
No, because of the materials' characteristics. The material that is appropriate for milling is MDF. Melamine can be used for some of our designer's solutions.
What is the difference between safe-type lock and a profile cylinder lock?
The difference between safe locks and cylinder locks is that their codes are situated in different places – with safe locks it is situated inside the lock and with cylinder locks it is inside the profile cylinder itself. That makes the cylinder, together with its protective plate, the most obvious and therefore the most vulnerable spot of the whole locking system. That is why we have selected a profile cylinder that corresponds to our image of a producer of doors of high quality and of high security class. It is produced by one of the global leaders in profile cylinders manufacture – the Finnish company Abloy. The „Abloy Protec“ cylinder is with an unique profile with no analogue on the market.
To what extent is the safe-type lock secure and which model has the best anti-burglar protection?
Our longterm partnership helped us gain trust into the Italian CR-Serrature locks' quality and the security they give. Different safe locks that we offer bring different level of security. Our experience lead us to the conclusion that the “Garant” lock is best protected. This is the basic lock model plus a decoder made of tempered steel and installed in front of lock's aperture. This additional decoding device gives the highest anti-burglar protection because of the restriction it imposes on any object from reaching into the lock's core.
What is the advantage of the “ABLOY” profile cylinder over the ordinary profile cylinder?
The “ABLOY” profile cylinder is produced in Finland and is the only cylinder without springs with a patent for the key and the lock. It is extremely weather-proof. Key duplication is possible in authorized locksmith's workshops only after representation of ownership documents.
What should I do if I loose the key from my safe lock?
Our company has a solution for code alteration for each lock we offer. This problem is most easily solved with the Ti Cambio changeable code lock, which allows code alteration without need for disassembly.
What is the reason for Solid not to work with customers' locks?
Solid gives warranty for its doors as a complete product, which includes solid door construction and elements of highest class, produced by established European locks, hinges and panels' producers.
Can a door be installed without a ready floor?
Yes, it can. It is enough for our specialists to know what the floor's final level is going to be.
Can you produce a two-leaf door?
Yes, all security door models can be produced in a modification with two functioning leafs. Our two-leaf doors' idea is to give you maximum comfort and mobility when needed.
What is the difference between the 40 and 50 Series?
The 50 Series doors are characterised by a thicker metallic construction. This thickness leads to: • better mechanical steadiness of the door • incorporation of an anti-drilling plate in the lock's area • double trilateral insulation (on door's leaf and frame) • adjustable threshold and a deviator • possibility for installation of an electromechanical lock This gives the doors from the 50 Series a higher class of security and better sound and thermal insulation characteristics.
How much does a security door weighs?
Our security doors weigh differently depending on their construction and additional elements installed into them. On average our doors weigh between 70 and 90 kg.
May I address your company if I have problems after expiry of the warranty period?
Yes. We offer warranty and non-warranty 24 hour servicing, so that we can fully satisfy our customers' needs.
How long is your doors' warranty period?
The warranty period is 1 year long.

There are many advantages of double glass over single: double glass gives better sound and thermal insulation, better aesthetic appearance of the whole door (also there is a possibility for building in of a decoration elements into the double glass) as well as greater durability.
