General information:

Galvanized Steel is used in our doors. This is an important detail, as the lamination on galvanized steel material ensures best adherence for polyurethane and paint applications (Cleaning of Dkp and black steel sheet surface, exposition to grease and corrosion). Also, it prevents the corrosion of the steel in the course of time due to the weather conditions. Thebasic rule to protectthe steel against corrosion is coating it with another metal, including zinc. When the steel is coated with molten zinc, after the chemical reaction, the zinc covers the surface of the steel. Zinc, not only adheres on the surface of steel, such as paint, but becomes a part of the steel. For this reason, it is used in shipbuilding, automotive industry and the construction industry.

We are using Polyurethane in the door as filler. We are injecting the liquid polyurethane casting, our special chemical formulation, through automatic high-pressure centrifugal casting system, in to the door, and ossify in 45 density under our 300 tons of press. Due to the many advantages that will be described below, and as opposed to the other inner filling materials (glass wool, rock wool and foam), adds a monoblocintegrityand over 40 tons of strengththe surface of the door. It also prevents inner corrosion of the steel material and highacoustic andthermal insulation.

Advantages of Rigid Polyurethane Foam Filler of the Door:

1. Polyurethane has a smoothfoam structure, 90-95% of the cells in the structure are closed. This provides perfect heat retention to polyurethanewhichis known the best insulatoraround the world. It has the lowest coefficient of thermal conductivity. (ƛ = 0.0023 Watt/ K.h.). Polyurethanes also provide sound insulation up to 50 decibels.
2. Polyurethanes have good adhesion properties. They adhere to almost any surface applied to. Polyurethanes have high dimensional stability. They show no expansion between -30 and +80 ° C and they don’t leave off the surface they bond.
3. Polyurethanes are long-lasting insulation material. Their conductivity values increase up to ƛ = 0.0025-0.0027 Watt/ Kh.
4. Polyurethanes don’t produce bacteria, don’t decay, and they are odorless, hygienic and contemporary products. In this sense, these products are environmentally friendly products.
For this reason, they are being used in automobile industry, transport, refrigeration, insulation, furniture, electronics, industrial parts manufacturing, shoe soles, and the health industry (biocompatible).

Surface coatings and protections;

We are coating special lamination on steel and we are able gain a wooden aspect without using wood, etc. in many of our lines (Hg, Silver, Classic and Monoblock series) they are laminated with special pvc coating for giving a wooden appearance in special lamination line. Coating gains a very high adherence, retention with special lamination, available only in FalezÇelikKapı by using NordsonPolyurethane system, and provides an extrastrength against surface scratches. Also,it is the only product, without using wood, providing a wood appearance, that can be used for many years in areas exposed to outside weather conditions. The use of the same technique in Tuana series, especially in door frames, shows our differences in interior and exterior,in terms of coherence between the frame and door leaf.

Advantages of Nordson Polyurethane Lamination over Other Coatings and Paint Applications

1. Its difference with MDF and wood applications, which have a porous structure, since the lamination material coated is the steel, it doesn’t wet and doesn’t leave off the coating from the surface.
2. Since the coatings on Mdf and similar materials are gluewhich reacts with heat,they react again with the heat changes. While distortion, blistering occurs, as the reaction and incineration in Nordson Polyurethane lamination is finished, no problem occurs in temperature changes.

For this reason, this technique is preferred white goods, aluminum siding, pvc joinery etc. industries. • The aluminum profiles rotating around the door leaf are our own design, those profiles ensures an aesthetically pleasing appearance, in which the rivets or screws are hidden, where its standards remain unchanged.

Its advantages over applications with strips made of stainless or static painted:

1. As stainless or static coated over steel materialsare taken as a plate, cut and bent in metal processing machines, deflections in view and standard deviations occur. In aluminum extrusion profile,an infinite number of same standard material and a superior appearance is obtained.
2. In aluminum extrusion profile,by hiding screws and rivets, an aesthetic appearance is obtained. In other applications, the screws or rivets of the plates are fixed from outside and stayvisible at all times. During the application, the deflection and collapses occur.
3. By creating gasket slots and containing seals and couplings in the slots, the gasket can be fixed better. In other applications, fixing can be applied only on the head gasket. This creates breakaway risk in time

OUR DOOR PRODUCTION TECHNIQUE:

• We make our doors in monobloc shape not pieces or steel profiles, but as massive, by bending and stranding the whole steel plate in high tonnage (750-900 tons) presses. As an example, we ensure an integrity like a door in the automotive industry, metal bumper, pots etc. We are reinforcing the locks and hinges with 2-3 mm thick reinforcement wefts. In steel construction, we aren't gathering various steel pieces with welding and spot welding, but combined with high tonnage presses and special bending machines, crushing corners of 68-90 mm thick, as a door leaf in order to provide high warping safety and robustness.
• In "Furnished Quartz Series" and "Glass Series" products,main door leaf is of the above specifications,monoblock, the desired furniture is added onto the door. By completing this furniture, with special anodized aluminum, we are giving an aesthetic and durable look.
• Our door frames are 2 mm thick and adjustable frame. As with all our production,dimensioned in cnc machines, it is installed after the necessary holes are opened. In our door frames, 4 types of manufacture are available
  1. Standard static coating application
  2. Tuana series, the front view is of the same feature with the door, laminated and disassembly application.
  3. Wooden door frame application on static coating frame,
  4. Coating the inner part of Quartz series door frame with decorative aluminum frame
• Theaccessory completing the door, lock, strike plate, adjustable pawl, the hard lock pins are carefully selected and implemented. Especially the strike plate, adjustable pawl and cover have an aesthetic appearance,provide a great convenience in use and assembly. Except our "Monoblock Series",internal and external door handles are stainless. The door armor is covered with inox steel. The security is a sine qua non for a steel door. All these features combine to create FALEZ STEEL DOOR which is already safe and robust.
