Major construction company Manufacturing plant for the production of lightweight steel thin-wall structures Innovation Center

METTEM-BT

ABOUT THE COMPANY METTEM LSC Company was founded in 2010 and now appears to be one of the key enterprises of the Group of Companies METTEM, representing more than 15 industries focused on innovations, operating in various industries.

STAGES OF DEVELOPMENT

Experts of METTEM LSC, after studying foreign experience, came to conclusion that one of the most advanced construction technologies was the technology of lightweight steel thin-walled structures. The company started the development and promotion of technology of lightweight steel thin-walled structures in Russia, and later continued the development, expansion and improvement of the technology. Initially, lightweight steel thin-walled structures were used only in the construction of residential and commercial buildings with height up to 3 floors. METTEM LSC Company made a breakthrough in the Russian construction market, worked up the enclosing wall panel for a multi-storied building based on the lightweight steel thin-walled structures. At the momment the Company owns two patents on the enclosing wall panel (thermal panel METTEM), as well as a patent for an innovative way of the erection of external walls of multi-storied buildings from these panels. The construction technology based on thermal panels (METTEM technology) is becoming more and more popular, as it allows to reduce construction time, to reduce significantly current costs for the construction and subsequent costs for maintenance of the buildings.

In Slantsy settlement of Leningrad region the House-Building Plant METTEM LSC has been started up, where the following types of products have been carried out on a commercial scale of production: - metal production (galvanized steel profile, thermo profile, smooth sheet, strip and so on); - prefabricated hangars of lightweight steel thin-walled structures / black metal for industrial, commercial and residential purposes; - patented wall thermal panels METTEM (used as enclosing in high-rise construction); - complete sets for low-rise prefabricated buildings (cottages, townhouses, houses for seasonal living).

A partnership agreement with one of the largest Finnish manufacturers and suppliers of steel and metal construction RUUKKI Company has been signed. Projects of apartment buildings 3-16 floors high have been jointly developed, based on the use of metal frames RUUKKI and wall thermal panels METTEM as enclosing constructions.

The company started producing wall enclosing thermal panel METTEM with readymade facade. The new technology of the erection of exterior walls of buildings with the use of "lock" method of installation of wall thermal panels METTEM was developing.

The production of a new type of wall enclosing thermal panels METTEM filled with polystyrene concrete, as well as the internal walls of polystyrene concrete has been started. The company launched a new line of products for individuals named "Weekend Designer." The range includes designs of prefabricat-ed houses, garages, outbuildings for cottage and garden, which can be made with one's own hands. The certificate of conformity of enterprise standards and requirements of the European Union has been obtained (METTEM LSC products are authorized for mass implementation in all EU countries). In July 2015 METTEM LSC Company joined the Association of Steel Construction Development.

2015

METTEM LSC Company started the design and construction of social facilities: preschools, medical and obstetric centres, sports and recreation complexes, residences for elderly, schools (up to 30 students) for small settlements, as well as objects of "social housing" (multi-storeyed buildings up to 20 floors, apartment buildings up to 3 floors, townhouse settlements, cottage villages). The company has received a patent for the construction of kindergartens of its unique technology.

2012

METTEM LSC implements thermal profile which is quite ready for further assembly into the frame: - all the elements are made in the order of their further assembly; - profile is cut in size of zero tolerance; - profile is produced with all the necessary technological openings, crimps and notches in the joints of the elements; - markings of cavities ("bulges") are made at the attachment points.

Highly alloyed galvanized steel is used for the production of thermal profile, which is characterized by high value of the ratio of material strength to its density, allowing you to create lightweight designs with high load carrying capacity.

METTEM LSC is a complete cycle plant for production of lightweight steel thin-wall structures, which has been put into operation in 2011 at Slantsy settlement of Leningrad region. Manufacture workshops, warehouses with convenient access for freight transport, administrative buildings are located on the area of over 4.5 hectares. The initial production area amounted to 1728m2. Due to the increased volume of orders 2 new assembly plants of total area 4128 m2 have been additionally built and put into operation in 2013-2014.

METTEM LSC is equipped with the most modern machinery. In 2011 Finnish partners of the company SAMESOR acquired high-tech production line for galvanized thermal profile which is the main element of lightweight steel thin-wall structures. In 2014 three additional production lines of lengthwise and stud thermal profiles as well as the profile of a "lock" connection were also acquired.

Lengthwise thermal profile (U-shaped) Stud thermal profile (C-shaped) H, U ("lock") thermal pro�le

METTEM wall thermal panels are assembled at the plant. Assembly tables are equipped with carrying rollers to move the assembled structures and with hydraulic-powered elevator devices to eliminate manual turning of panels during the assembling. The process is operated at a standardized procedure: specialists of the plant produce the operations strictly according to the instructions with the constant quality control at each stage of the work. All this allows obtaining finished panels with a maximum tolerance of 2 mm.

Thermal profile is made of high alloy galvanized steel of 0,7-2,0 mm thickness; the thickness of the zinc coating is 275g / m2, with galvanizing of the 1st class. Thermo profile differs from the other types of metal profile by its thorough cut through, allowing to increase significantly the heat flow path. This feature of the thermal profile and constructions manufactured on its basis solves the problem of "thermal bridges", which are formed across the cross section of the wall at construction from the standard steel structures. Due to high heat performance structures based on thermal profile allow to reduce significantly the costs of maintenance of buildings and to reduce the burden on urban networks. Thermal profile is successfully applied for economical construction even in the Far North.

METTEM WALL ENCLOSING THERMAL PANEL FOR MOUNTING WITH A BEARING ON THE FLOOR SLAB

METTEM wall enclosing thermal panel for mounting on the floor slab is designed so that the main part of the panel intended for closing of the wall opening has additional elements above and sideways. At mounting the upper part of the panel abuts the floor slab, and a side part, respectively, to the pillar. Thereby in the outside of the building no

additional thermal insulation of the facade at the junction of wall panels to the floor slabs and to the pillars is required. In addition to the insulation, such geometry of the panels and the method of their installation provide a smooth surface of the whole facade, ready for finishing by facing materials.

METTEM HINGED WALL ENCLOSING THERMAL PANELS

METTEM hinged wall thermal panels are standard METTEM wall thermal panels of 150-250 mm thickness. METTEM hinged wall panels are to be mounted to the floor slab using a specially designed system of brackets. Brackets are attached uprights to the frame of the panel in the factory with

the help of self-tapping screws and the brackets are mounted to the floor slab through an anchor connection. METTEM bracket system ensures even distribution of the load on the panel and the strength of the assembly.

It is possible for METTEM hinged thermal panels to use a finished facade (LATONIT) and a hinged ventilated facade (ceramic granite / facade tile FASADOFF)as well.

METTEM SYSTEM OF BRACKETS

METTEM HINGED WALL ENCLOSING THERMAL PANEL WITH "LOCK" CONNECTION

The frame of METTEM hinging wall panels is equipped perimeter-wise with special “interlocks” profiles – U (“flange”) and H (“slot”). Wall panels are mounted on the frame of the building by means of hindging, bonded together through a “lock” connection: U profile comes into H profile; at their connection node some insulation material has to be placed.

The innovative construction of the exterior walls of buildings with the use of “lock” method of installation of METTEM wall thermal panels allows you:

to reduce significantly the time of construction; to minimize the human impact on the process of mounting and simplify it as a whole; to provide 4 lines protection against penetration of external weather elements (rain, wind) into the joints.

FACADE SOLUTION OF METTEM WALL ENCLOSING THERMAL PANELS

LATONIT colored fiber cement slab is used as a solution for the readymade facade. It is the material with high strength and it gives a modern and vibrant look to the building. LATONIT slab is capable to withstand extreme weather and climatic conditions, to resist actively against chemical attack, it possesses a high hardness and a wear-resistance of the surface. It can be used in the architectural decisions of facades of any complexity. Sanding and cutting of LATONIT slabs, their acrylic and UV-lacquer coating for METTEM wall thermal panels are produced at the Italian equipment factory. LATONIT slabs are coated at external and end surface; UV-lacquer coating is made across entire surface of the slabs.

INTEGRATED RESIDENTIAL HOUSE CONSTRUCTION

RESIDENTIAL HOUSES AND BUILDINGS FOR ADMINISTRATIVE AND HOUSEHOLD PURPOSES UP TO 4 STOREYS

Company METTEM LSC has developed integrated solutions for fast and high-quality construction of residential houses.

For the construction of low-rise (up to 4 floors) dwelling houses and buildings for administrative and household purposes a special series of METTEM enlarged wall thermal panels - PM-U - has been developed.

At the heart of the integrated approach there is a use of the metal frame as a load-bearing frame of the building and the use of METTEM wall thermal panels as enclosing. This technology allows to erect residential buildings from 3 up to 16 floors high.

DIMENSIONS

Panel of the series PM-U has a non-standard size: the maximum height is 12 m (including the part of the parapet), width is 3.2 m.

TRANSPORTATION

Wall thermal panel of series PM-U is transported in a horizontal position in a standard or low-bed wagon.

MOUNTING

Panel of the series PM-U is set to the design position with the truck crane. The panel is attached to the overlap disks, using the system of angles and plates. The panels are fixed with each other through a lock connection, which accelerates up and simplifies the process of installation and provides the maximum protection of the interpanel joints from environmental factors.

FACADES

For residential buildings the wall panels of the series PM-U are available both with a ready-mounted facade (colored fiber cement slab / flexible stone) and in the standard configuration under hinged ventilated facade with ceramic granite / FASADOFF facade tiling.

For administrative and household buildings as well as for buildings such as barracks it is possible to use cheaper finishing materials (facade cassettes, profiled sheet, etc.).

CONSTRUCTIVE PROPOSAL

MULTI-STOREYED RESIDENTIAL HOUSES UP TO 25 FLOORS At the heart of model projects of multi-storeyed residential houses there is a sectional approach.

The variety of sections provides the variation of layout schemes. Sections are combined with the requirements of insolation, thus achieving optimal planning solution.

METTEM wall enclosing thermal panels of standard sizes are used (their max height is up to 3.3 m, max width is 7 m) as the building enclosing structures METTEM with a finished facade (colored fiber cement slab / flexible stone). Wall panels are mounted by means of hinging with the help of system of brackets.

KINDERGARTENS ARE FOR CHILDREN!

Construction of kindergartens is one of the key activities and it is the most relevant METTEM LSC activity. Creating projects of kindergartens, we have studied the best international and Russian experience in design, taking into account modern trends in building technology and, of course, thinking of the children themselves.

We have tried to develop the most comfortable and safe environment for physical and mental development, education, training, games, communication and entertainment for children.

We have embodied our ideas in the designs of modular kindergartens.

Structurally the building of a kindergarten can be designed and built based on the framing of any type (monolith or metal prefabricated ferroconcrete cage). Enclosing wall is made of patented METTEM wall panels.

Thus, based on the proposed integration design and modular units at attachment to each specific site we have only processing of foundations and planning of communicational corridor-vestibule areas, ensuring correspondence of the assigned project to hydrogeologic, geographic and topographic conditions of the site.

CONSTRUCTIVE PROPOSAL

A series of modular kindergarten projects is designed for the unified approach for the projecting in various climatic and geographical conditions in areas with different geometries and configurations. The basis of the project concept is to create a modular system (standardized module of the group cell and module of the serving premises) so that standardized natural lighting is carried out only from one side (on one wall) of each module, and the other three parts can provide a lock of modules among themselves.

In 213 METTEM LSC Company received a patent for the construction of kindergartens according to this modular technology (Patent No 126740 "The building of preschool educational institution").

MODULAR SYSTEM

An integrated approach to the construction of educational facilities: presentation of project, construction management, equipment by furniture, educational and visual aids.

The unique product for the construction of kindergartens in remote areas. The complete set of building comes to the platform: 80% of the building is made at the factory.
