Glass reinforced polyester (GRP) is a light, durable and tough constructional material which can be molded and fabricated into all manner of products. It is a composite of a resilient durable resin with an immensely strong fibrous glass. Polyester resin is used as the main component and is reinforced with glass fibers to form GRP.

The characteristics of a very strong and light weight construction material are particularly relevant when designing roofing features. GRP is chemically inert and corrosion-resistant and it also offers high levels of water resistance and will not buckle or distort in high temperatures. However, the greatest advantage of GRP over conventional materials is that it can be designed as a whole self supporting structure that can also be easily lifted into position and installed using minimum man power.

Using GRP thus saves time and reduces installation costs and maintenance fees making it an excellent roofing material.

These are construction materials specifically designed to be manufactured off site but later brought on to the real site. They are made up of factory built components which are assembled away from the main location. The most considered types are the Galvavolume and the Galvanized steel. Steel coated with aluminum zinc are the most commonly preferred prefabricated building materials. They prevent corrosion, fire and rust from destroying the building. This greatly reduces the construction cost.

Fabricated building materials are commonly used in the military buildings to improve on the security. The builders normally combine both cloth and metal materials when flooring. These materials are very durable and can easily be assembled. The ceiling is commonly made up of frames, beams, walls and roofs of steel.

Most commonly used fabricated materials are fiber glass, concrete, steel and aluminum. They are given consideration because of the hardness..

For a home or building that has more than one floor, stairs are an important feature. Straight stairs are preferred by most home owners because of the simple building process involved the demand and because of their simplicity, building them is not hard. Every place has its own specifications concerning the building of straight stairs and once you know the rules and the procedure, building straight stairs should not be a problem.

You only need to master what materials are used, for example, wood, metal and concrete and how to measure the three for whatever size of the stair you are building. Just ensure the stairs are safe for everyone. A couple of straight stairs design are available online that you can look at to have an idea of what you can make.

Due to their simplicity, straight stairs have relatively low construction costs compared to other types of stairs.
