CHAPTER FOUR
4.0 MATERIAL SELECTION AND FABRICATION DETAILS
4.1 Material Selection
Engineers are constantly faced with problems when it comes to the issue of materials that will suite his/her requirement for a particular project.
However, the following properties were put into consideration before selecting the best materials for the construction of the project (twin panel metal door)
i. Impact Strength: - This is mainly concerned with the resistance a material offers to fracture. The selected materials for the project offers a very high resistance to fracture and it is one of the most important factors considered before selecting the materials for the construction of the project.
ii. Environmental Reaction: - Environmental factor such as whether has to be considered before selecting any materials for executing any project. Therefore, the resistance of the selected material to weather condition like temperature and humidity was considered before selecting mild steel as the material.
iii. Cost of Material: - Before the construction of the project was selected, the cost of the materials was considered and a good quality materials was bought at an affordable price.
iv. Availability of Material: - Materials to be used for construction of any project should be readily available in the market so that the same materials with the same characteristic and properties can easily be found in market in case of any worn out or damage.
v. Economic Factor: - The material used for fabrication of the project was economically cheap, and attractive to meet the demand of people.
vi. Machineability: - The materials used for the construction of the project can be easily machined i.e. it is easy to cut into desired shape and size.
vii. Aesthetic Quality: - The materials used for the construction of the project was considered to provide for good strength, high degree of accuracy and good surface finish to make the project design more attractive. At the time of this project, the material that is suitable for the construction of this project (twin panel metal door) when the above properties were put into consideration is mild steel. Mild steel was used for the construction of this project due to the following properties
Mechanical Properties
i. Durability
ii. Malleability
iii. Ductility
iv. Light in weight
v. Good tensile strength
Physical Properties
According to spectrum of material properties, it states that the physical property of any material has the characteristics that are determined by virtue of their nature occurrence. Usually it can be measured without destruction test. It can also be determined through visual means.
Physical Properties Such as:
i. Metals have high densities
ii. Metals are good conductors of heat compared to non-metals
iii. Metals are lustrous for which they reflect nearly all wave length of light equally well.
iv. Metals are magnetic to some slight degree.

CHAPTER ONE - [ Total Page(s): 1 ]CHAPTER ONE1.0 INTRODUCTIONDoor is a movable structure that is used as a means of closing off entrances for security purpose and also for the beautification of the area. In the ancient time, doors were not used and the people of then live comfortably in peace since there is trustworthiness among them, but as time goes on, some people gang up to become an enemy of progress, they started stealing another people’s properties and also terminate their live. This brings the people of thos ... Continue reading---

prevent unwanted access to an apartment and to reduce the rate of
penetration of sunlight.The frame and panel is made of wood and the
leather is wrapped round the panel. The panel is joined to the frame
with the aid of hinges for adequate movement of the door and also to
allow for easy opening and closing of the door.ii. Wooden DoorDue
to the fact that doors made from leather does not guarantee unwanted
access ... Continue reading---
