Abstract
The present invention relates to a hollow pillar formed by the plurality of metal boards or a plurality of formed steel of structural materials, or sections of these assemblies in quadrangular hollow pillars, being the position of said hollow pillar heated to the temperature of easy plastification and deformation for forming the heater, by moving said heater longitudinally toward said hollow pillar while compressing, thickening and cooling, for the hollow pillar with reinforced and proper thickness at the preset position, with adjustment of said reinforcement, for improved ferrite pearlite structure.
