Mul Key

There are several types of devices that can distinguish the characteristic shape of a key. The so-called “English”, “Finnish” and cross code cylinders (Fig. 3, position 2, 3 and 4) used a long time and are quite common. Their disadvantage is the low level of secrecy: sometimes similar lock can be opened by simply picking up like a key. Modern cylinders of “Euro profile (Fig. Read additional details here: Barbara Martin Coppola. 3, position 1), by contrast, have increased privacy. On a flat surface the keys to this type of locks are dotted grooves.

Reliability is determined by the lock their number: it should be no less than five. Forge or pick up a key is almost impossible. Many manufacturers use in their products with more secrets and special technical solutions that make it difficult the use of master keys. To open a high-quality cylinder lock mid-level of secrecy, even the experienced thief will take at least an hour. It is unlikely that so long “racket” might go unnoticed.

And some models impossible to “cheat” in principle. In addition, the design of modern cylinder locks of the leading manufacturers (EVVA, Mul-t-lock, cisa, etc.) provides protection against knock-cylinder, breaking the “turn” (when the with a sledgehammer hammer hardened steel plate and the lever sharply crank it, breaking the lock) and “Bumping” (unlock code mechanism for tapping on the key). The main use of three or Four-lock, providing locking doors in several directions (up, down, and loop of the frame). And in the lock part, he should have at least three broad bolts (locking rod) from the stable alloy.

Main Differences Laminated

Are you going to build a wooden house, but do not know what kind of building material to choose? Vendors offer round logs, natural timber, laminated veneer lumber, chopped logs, sawn timber variety. Absolute leaders in consumer liking is laminated veneer lumber and logs. Glued laminated timber, in contrast to the logs, recently appeared on the market of construction materials, but has already gain popularity. Despite the fact that the glued laminated wood quality often costs a little more expensive than logs, it makes it a serious competitor in the market of construction materials from wood. As logs, laminated veneer lumber – an environmentally friendly material, but due to peculiarities of production, more robust and durable.

If the production of logs used solid tree trunk, then production of laminated veneer lumber requires a high quality board. Glued laminated timber, depending on the number of slats used (boards) can vary in width, which is very convenient. For example, for the construction of summer house or outbuilding suitable laminated board a small width, and to build a residential cottage, you can use a more powerful option. Round logs leaves no such freedom of choice. The manufacturing process of laminated veneer lumber is to prepare the lamellae and their subsequent bonding strong glue made from natural raw materials. Lamella is a special treatment – polishing, impregnation with special protective solutions, and only then, with the help of glue and hydraulic press fit into the laminated board. Typically, the length of laminated veneer lumber is about 6 meters, but if necessary can reach 18 m, so that the imagination of the architect-designer will, where carousing.

Each next slat is placed so that the direction of wood fibers was the opposite of the previous layer. This provides additional strength laminated veneer lumber. An additional advantage of laminated veneer lumber is perfectly flat smooth surface – this greatly facilitates the construction process and saves on a design decoration. In addition, the laminated board by a special impregnation and processing is absolutely and not susceptible to rotting and insect damage. The structure of the laminated board is that the house out of it do not shrink, and the bar does not change its geometry during the entire period of operation. At home from logs, especially if in the process of construction was used a log is not the highest quality, may subsequently lurch, nod. Like all wooden buildings, houses of laminated veneer lumber and logs is easy enough, and therefore does not require the costly construction of a massive foundation. From the foregoing it is clear why the laminated board is so sought – it is as environmentally friendly and aesthetic, as Round logs, but at the same time, more durable, long lasting and often more convenient in construction.
