For painting metal parts are typically used as a standard Kuzbasslak 9c), soil (slightly better), or that showed good performance quality paint Hammerite Metal Finish (or powder coating). Improving the standard of heat and sound insulation properties of products developed by engineers at the expense of some businesses a set of special technological solutions including: changing the configuration and auto filler frame, making special insulated door panels and frames for exterior (communicating with the atmosphere) or single (in the absence of the second wooden door) door units, elimination of air flow as between the door leaf and a steel box and between the steel frame and the wall. Evaluate the proposed approach by the formation of complete door set for its true identity. should evaluate itself with the manufacturer for its professionalism. We can distinguish the following features professional approach a particular firm: The license, which confirms the presence of in the company of the complex necessary for the production of equipment and tools, as well as the availability of workers and engineers with the appropriate skills, education and training, a certified professional. VMWare can provide more clarity in the matter. bodies Rossii.Nalichie contract specifying the order of payment, warranties and terms of ispolneniya.Spetsialno developed forms, which clearly indicate all product specifications, including size, fit, and full a clear account stoimosti.Nalichie print multipage directory listing services and a complete price list of products. The greater range of additional services can provide a firm claiming an individual approach to customer, the higher the level of professionalism. Question often arises on the date of manufacture. And really, how long you will be manufacture the product and the time is considered normal in the case of an individual order? To reliably answer this question must take into account the following fact. Taking into account the specifics of the current market of steel doors, we can conclude that the basic prices of firms producing individual products, correspond to rates of firms producing standard products mass-production way. Ie prices for the basic equipment of approximately ravny.Odnako Flow firms (which are heavily disguised as 'work-to-order') easily recognized by the inventive production time – 1 day. This should be a signal: it is technically impossible to produce steel block in the normal mode for 1 day. In most cases, these firms have a ready-made doors of several types of sizes. In this case, when you install the products available in the real door is made of technological adaptation that negativnoskazyvaetsya on strength and appearance of the design, and, besides, customer Imposed some pre-compiled a complete set of products. Firm professionals will be designed exclusively your product without regard to nashtampovannye billets, and, most likely, this process will take at least 3 days, and for products with a special finish – no less than seven. This should not scare – some operations are technologically require considerable time, and hurry them only harm). Another question concerns what kind of door to choose all the same: the Russian or imported. Experts assert, based on years of experience in the field of passive safety systems that in the same price category steel doors of honest Russian producers is always much surpass foreign analogues. Russian – then manufactured on a foundation of intellectual labor obremennennogo our history, but nekostnogo and who knows how to do 'with soul', in the presence of the normal managerial and engineering staff (in production), the people.
