Metal designs - integral part of modern construction. Thanks to their features of construction, buildings turn out tamperproof, they are built more simply and quicker. Today metalwork applies to construction of trade pavilions, logistic and warehouse complexes, mega-markets, engineering buildings and shops and in some other constructions of different function.
Advantages of application of metalwork in construction
Broad application of metal designs in construction is explained by number of their advantages:
- speed of design, production and mounting; - convenience of transportation;
- small weight; - high strength, reliability and durability;
- possibility of carrying out installation works in any weather; - fire safety; - seismostability; - low cost; - simple base; - power profitability; - simplicity of operation.
Production of metalwork
Production of metal designs demands very responsible approach. Except that process of production rather labor-consuming, so also any made mistake is capable to turn into tragedy as a result. Only the specialized enterprise equipped with the necessary hi-tech equipment and having modern production base can make qualitatively design of metal. Having entrusted this work to handicraft masters, it is possible to receive as a result not only low-quality, but also hazardous to health and lives of people product.
Production of metal designs assumes that such products: - will sustain powerful, long-term and difficult multilateral loadings without deformations and breaks; - will become resistant to wear of all constructive parts and fastenings, rust and cracking; - rises of temperature, winds, hard frosts, hurricanes, earthquakes will be able to resist practically to any natural phenomena, whether it be. At production of metalwork the special high-quality steel is usually applied. Fastening of separate parts among themselves happens to the welding help. The easiest, mobile and well trasportabelny designs are made of aluminum. It is quite strong and wearproof material.
By production of metal designs both rolled, and sheet types can be applied became.
Production of metalwork usually happens in 3 stages: - design (it is the most important stage); - production (metal preparation, processing of metal wares, welding and assembly of metalwork, drawing corrosion-resistant or other protecting cover, painting of ready modules); - mounting of metal designs. Design – one of the most responsible stages in production of metalwork. From that, calculations of dynamic, wind, static and other loads of separate elements and product in general are how precisely made, its durability and durability depends. At this stage necessary documentation (schemes, drawings, plans, etc.) is developed.
If necessary on projecting phase exploration works can be carried out to find out the soil frost depth, its composition, proximity of ground waters.
After calculations are executed, the project and the estimate all permissions are approved, got, inspection of material and its preparation for production of design is carried out. At the same stage priming mixes, paints and varnishes and other finishing, decorative, fire-prevention and anticorrosive structures are chosen. Processing of metal wares includes its gibka, cutting, drilling and coredrilling, stamping of elements of irregular shape and other types of machining of parts of future metal construction. This stage differs in the increased labor input and takes away most of all time. Process of production of constructive parts of metal significantly accelerates because of use of the latest automated equipment which excludes intervention of the person and emergence of defects. Welding of separate elements of metal construction or production of completely welded product can be made in different ways. The most advanced types of such way of connection – laser and plasma. After parts of product are connected, control tests of welds are made. It occurs by use of nondestructive methods, for example, the ultrasonic equipment. Also visual examination is important. Further degreasing, grit or shot blasting, priming, painting, anticorrosive processing is carried out.
Mounting of metalwork
Mounting of metalwork can be made in different ways, but the main condition is its high quality. Therefore construction can be entrusted only the serious organization in which staff there are professional spidermen and assemblers with high qualification and wide experience. For exact mounting the special equipment is used: levels, elevators, laser levels with high accuracy which allow to carry out works at the minimum admissions. The price of installation works can depend on various factors: - complexity of design; - amount of works; - seasonality, time and venue of construction; - mounting of metalwork is on the ball; - availability of additional communications and designs, etc. Ideal option if you have opportunity to order the project of metal design, production, mounting and delivery of all building in operation in one organization. In other cases it is possible to use service of the general contract — to find the company which will agree on the project will check quality of materials, will install design and will hand over object in work. That is, the general contractor completely takes the responsibility for work of the third parties.
