CONSTRUCTION OF STEEL SHELF

ABSTRACT

The aim of this project was to acquire the constructional and fabrication knowledge by we, the students of chemical engineering by constructing a steel bookshelf.  This work exposed us to many things like material for engineering and their requirements.  It also exposed us to other fields of engineering like metallurgical and material engineering.

In this constructional project, mild steel was used because it has qualitative properties in construction.  The shelf constructed has five compartment and was done with the structure of the steel shelf drawn on paper, market survey and procurement of the needed material, marking out and cutting, fabrication and welding, filling and paining.

The shelf has a dimension of 1524 mm height, 941.4 mm width, 355.6 mm breadth.  The framework of the structure consist of 25mm square pipes and guage 12 electrode was used for the welding process.  The shelf was painted to prevent corrosion attack and filled to smoothen the surface of the structure.

During the course of construction, some safety measures were adopted to avoid hazards and accidents.  They include-wearing eye goggles, safety boots, overall, hand gloves.
