Introduction For the manufacturing of support plates it is necessary to start from the plane shape of the work piece, type of the material, conditions established through design and dimensions of the piece.
Industrial processing of the plates uses plasma or laser cutting for large plates from different materials (steel, copper, aluminum) but the costs of the acquisition and maintenance of these devices used in processing are higher.
All these factors are presented in the next formula: C= Cm+Csc+Co+ Cdt+ Ctdv (1) where: · C – total costs inquired for the fabrication of the product; · Cm – costs of the materials: it means the taking into account specific factors as the planar surface area, thickness of the material, specific weight of the material, specific coefficient related to the utilization of the material and cost per unit of the material; · Csc – costs with staff meaning net salary and other legal charges (social charges, state budget, etc.), average time per operation for the production of a single unit, average time for preparing the devices for a proper functioning and the number of products · Co – costs with overheads: it means the taking into account the costs related to the consumption of the electrical energy, water, technical gases and other specific conditions required by the process; all these factors can be summarized as 2 – 2,5 % from staff costs · Cdt – costs with the depreciation

The construction effect of passive protection system The analysis of expressway slope flexible protection method and other protection methods in comparison The traditional protection engineering uses rigid materials which are composed of cement, stone, concrete and so on for the main building materials.
In the broken slope surface, when a large number of lose materials, pumice stones and high water sensitivity rocks appear, the adhesive strength of the protection structure and slope surface is difficult to guarantee.
The mechanical equipment and materials of passive protection required are more than other methods of solid.
