Aluminum - lightweight, durable, corrosion resistant, easy to clean construction material, long-life, environmentally friendly, does not contain impurities of heavy metals, does not emit harmful substances by ultraviolet rays and keep working in all weather conditions with temperature changes from -80 0 C and +100 0C. Aluminum - lightweight, durable, corrosion resistant, easy to clean construction material, long-life, environmentally friendly, does not contain impurities of heavy metals, does not emit harmful substances by ultraviolet rays and keep working in all weather conditions with temperature changes from - 80 0 C and up to 100 0C. Aluminum is better than other material retains its structural properties with temperature changes. After the surface treatment of aluminum products, they become resistant to the harmful effects caused by rain, snow, and smog. One of the drawbacks of aluminum is that the direct contact of aluminum with other metals can cause leakage of electrolytic reactions, which leads in turn to a strong elektrokorrozii aluminum, until its destruction. To date, the technology was perfected manufacturing aluminum profile - the main material for making light and thin structures, which possess the same strength and durability as traditional structural building materials. Aluminium profile, usually made of three-Alloy: aluminum, magnesium, silicon. Aluminium has high thermal conductivity, so all the leading manufacturers produce two types of profiles, which differ in scope: "cold" profile, with high thermal conductivity, without a thermometer insert. Suitable for doors (both internal and external) in unheated buildings or for the manufacture of interior doors in heated rooms, "Warm" combined profile, low thermal conductivity, which has insulating box. Intended for the manufacture of exterior doors in heated buildings. In the "warm" profile outer and inner shell Profile interconnected insulating insert (sometimes mistakenly called "thermo"), which interrupts the flow of heat, thus providing, better thermal insulation. Along with the implementation of heat-insulating function jumper, also sees a static load, and not at the expense of its durability. Thermometer insert, usually made of glass fiber reinforced polyamide. Its thermal properties allow it to withstand temperatures up to 200 0C, which allows coverage profiles powder enamel kiln drying, in assembled form. In designs of aluminum profiles used double sealing around the perimeter or secondary seal and the seal on the porch of the (internal), which provides high performance in the wind, water, and soundproofing. As seals are used, mostly, EPDM (synthetic rubber), often in the form of vulcanized at the corners frame, or silicone. The most advanced technology surface treatment of aluminum profiles are: powder coating, followed by roasting (Color RAL); anodized surface of products under the natural color of aluminum, gold, bronze, etc. The design of corner joints of aluminum profiles: A - REYNAERS; B - ALUVAR; When powder coating layer is an elastic plastic polymerized directly on the painted surface, with very good adhesion, as a result, creates a shatterproof coating with anticorrosive properties and working temperature range from -60 0C up to 1500 C. The thickness of the coating can be from 30 to 250 microns. The design of "warm" profile allows you to do two-color profile (internal and external parties - in different colors). For long-lasting functioning doors made with aluminum profiles are very important qualitative performance of the angular connection profiles. Stable and tight connection of corners and joints can be achieved through special nagelnyh or punching compounds, followed by sizing corner joints with special glue-sealant. Modern technology provides the bonding stiffness, reliability and accuracy of treatment of joints. Aluminium profiles for doors can be divided into several groups: System profiles balcony - virtually the same as window systems, and in practice, most often used for balconies window profile. It is only necessary to take into account the width of the profile to make it possible to establish a closure at the balcony door. Requirements for a balcony profile for heat and sound insulation requirements are similar to the windows; profile system for interior doors - cold profiles, system profiles for exterior doors - "warm" profile. To increase the stiffness of door designs, it is advisable to carry out the lower bolt from a wider profile than the rest, using a T-shaped, rather than the gusset. Door Profiles allow you to set a special door fittings (hinges, locking devices, etc.). If necessary, a special profile for the threshold. Leading manufacturers offer a large range of thresholds required to perform any civil engineering requirements. Channel:
