Apart from tarpaulin, panel coating and sheeting applications are made within our company. However, as tarpaulin is economically more convenient, and has easier and less cost of repair-maintenance it is the most preferred coating option. Its processing, mounting and maintenance are easier and quicker. We may compile the advantages of steel structures as follows: seismic security, conformity to weak surfaces due to its light weight, economic recycling due to demountability, high material resistance and elasticity, formation of large spaces, architectural freedom, rapid production and mounting process and reduction of the infra structural material costs. The production and mounting processes of steel construction components are significantly shorter than the other alternative materials. This enables the project design and pricing expenses to remain in the minimum level. Compared to other alternative materials, steel construction structure provides significant financial gain and time saving in the substraction and the preliminary work of the areas where reinforcement is required.
