Any customer who applies for the manufacture of metal structures to a manufacturing enterprise in St. Petersburg wants to end up with a high-quality product. In many respects it depends not only, as they say in the advertisement, on the "experience and high qualifications of the personnel," but also on the equipment used and, no less important, on the correct organization of work. We will focus our attention on the latter.
In general, the production of metal structures consists of six main operations - material preparation, processing, assembly (welding, bolting, riveting), priming, painting or galvanizing, and shipping of finished products. Accordingly, the organizational structure of the plant must correspond to the conduct of these operations. Some operations can be combined in one workshop, such as metal preparation and processing, or welding and assembly. To ensure the work, auxiliary shops and services should be organized - compressor, oxygen station, hardware and electrode section, boiler room, transport shop, pumping station, administrative complex, etc.
The specific composition of workshops and services depends on the capacity of the plant, what building metal structures it offers, what their weight and maximum dimensions are. For example, the St. Petersburg plant organized production of steel structures in such a way that all main and auxiliary workshops are located in one building in Staraya Russa. Thus, the length of transport flows is reduced, the time and costs for the transportation of materials and products of various degrees of readiness are reduced. The cost of delivery of finished products to St. Petersburg or Moscow is compensated by the lower cost of real estate and wages in this region.
An important role is played by the organization of the movement of crane equipment - bridge or gantry cranes (for open areas). It can be parallel or perpendicular to the process flow. Parallel (longitudinal), as a rule, is used in workshops with a capacity of up to 20 thousand tons. The total length of the hull is 320 - 360 meters.
With a capacity of more than 40 thousand tons, the organization of the lateral movement of cranes is more profitable. This principle of planning can significantly reduce the area of workshops, which is very important for St. Petersburg with its land prices. Space savings are achieved through the shortest in the direction of the smallest size of the material or structures used. The length of the hull can also be 300-400 meters, and the area can be increased by increasing the length of the transverse span.
The degree of mechanization of workshops also plays an important role, which determines the productivity and range of products.
