Selection lightweight steel roof

Selection lightweight steel roof is the process of building a house began to enter the stage of the roof, then you need to choose the right material.

There are many choices of materials for roof construction. One of them, mild steel. This material started much used because, relatively cheaper, lighter, and more durable. Now the problem, the building materials market, there are various types of materials, brands, and prices of materials for this roof truss. Then had to choose which one?

Before buying, consumers need to be more thorough. Careful in identifying the materials and systems lightweight steel roof truss as a whole, not just an offer from suppliers or contractors. To understand the lightweight steel roof truss, we must understand first that this product is a product structure that supports roof loads, wind, and life under the roof later.

When choosing, there are four main components in lightweight steel roof truss to your attention:

Strength of steel. Steel materials have different levels of power. At present it is best to have a mild steel specification G550 or 550 Mpa melting voltage. This material is different from conventional steel, which has a melting voltage 300 Mpa (G300). But because the nature of the steel is corroded, the steel must also be given protection against corrosion. There are two types of protection; galvanize or coatings made of zinc, and zincalume made from a mixture of zinc, aluminum and silicon.

Pay attention to the design and structural calculations. There are several types of providers lightweight steel roof truss. Many well-known producers who use special software to create a design of the roof truss design and calculate the level of strength. Some other manufacturers do not use the software. Software is believed to be able to calculate the power level of the framework in more detail. In fact, the software can simulates the future burden of the roof truss. This software, among others produced detailed working drawings showing dimensions of the framework, the connection type and number of screws at each connection.

Installation and assembly of light steel frame. You need to ensure that the installer is not by any handyman. Convince yourself that the installer is a steel roof truss has a pair of worthy certificate. That way you get a guarantee that the design of the correct image to be ready to be installed correctly as well.

Periodic supervision of the supervisors who had been appointed by fabricator and the brand owners.
After it had been complete, do not forget your request letter and the installation of the product warranty.

Roof tile

Closing the roof tile is one of the most important part of the roof. selecting the type of roof covering materials are very determine the framework of the roof structure. There are many types of materials that can be used as roof cover, among shingle, tile, asbestos, fiber cement and steel or metal.

Based on their raw materials, tile can be divided into two, namely tile soil and concrete roof tile. Material basis of making tile clay soil is a good printed manual (with hands) or use a press machine, which then burned perfectly. While the concrete roof tile made from a mixture of sand or stone with cement using a printing machine. Based on the shapes tile consists of various types, including frog tile, hollow tile, flat interlocking tile, ceramic tile and concrete roof tile.

1. Tile frog.
This tile is called the frog tile because its shapes such as frogs.
Frogs have a field tile, and even the bottom of the elevation there is a frog-like, and in one of the grooved edge there is a trap. Frog tile making is carried out manually by hand and there is also the engine. So that the tile looks better at the time of installation and prevent the attack of mildew, it is in the paint this tile with tile paint. Indeed, at this time in the market many models tile frog that has been in the glazing with transparent color and transparent brown. The aim is to prevent the attack of mildew.

Basic materials such as tile clay frogs. Tile excess frogs are valuable light weight and inexpensive, but strong enough to tread on. While the lack of it among others in terms of which must require the exactness and accuracy. This pattern is caused by the zig-zag connection interlock system (such as the stone-brick) then the result is not neat if the tile rafter and tidy so that it does not splash will happens. In addition, the surface of tile is not in the enamel will easy mossy look so dirty. The impact is no less need for the installation lath o support roof tile used t more than that of using other types of tile.

Tile frog quite mild compared with other types, that is only about 1.5 - 1.8 kg per unit. Needs per meter square tile roof around 21 - 25 units. depending on the size of its tile. Slope angle at the time of installation of the roof is 19 without aluminum foil.

2.Flat interlocking tile.
Flat interlocking tile or tile usual this has a flat surface. Like tile frog, basic materials making this tile is no clay. Tile is most commonly used because the price is relatively cheap, installation is also quite easy. Requirement per square meter roof of 25 units with weight 1.5 kg / unit. Advantages include flat interlocking tile is cheap and lightweight. While the lack of it is weak or less strong for the board and easily affected lumut fell ill, so visibly dirty.

3. Hollow tile.
This tile is in the glazing and the non-glazing. Tile in the enamel should not need to be painted to prevent mildew and fungus attack. Specifications include hollow tile weight 2.3 kg / unit, the contents of 18 units per m2, the distance from rafter 40 cm, 25.5 cm distance from lath used to support roof tile,interlock system connection, and a minimum roof slope angle 19 degrees. Advantages include hollow tile enough light, cheap, and strong.
While the lack of it among others is required, among other necessary accuracy at the time of installation to appear neat.

4. Ceramic tile
Tile is strong enough compared with other types. Ceramic tile has many models and colors. Basic materials making this tile is clay. The process of burning through it at a temperature of 1100 C to the time for 18 hours. With this burning like the ceramic tile is quite strong and not porous. meaning does not come on the surface of the tile. Burning oven to its use so that the size of tile more precise and uniform. After combustion, the process of coloring is next and the tooth enamel. With enamel tile is able to reflect this summer for up to 90% so that relatively cold room underneath. Color choices available in the market quite a lot, including natural, orange, yellow, blue, green, maroon, tosca, brown, gray, and so forth. The specification is a heavy ceramic tile 3.2 kg / unit, the contents of 14 units/m2, rafter distance of 40 cm and an interlock connection.

5. Concrete roof tile.
Concrete roof tile has many models and colors, starting with the curvature model to model or flat arches. Also vary the color of brown, blue, green or a combination of 2 -3 color in a single tile. Raw material producing concrete roof tile is a mixture of cement, sand, binder, brace materials, and coloring materials.
In use, the materials of concrete roof tile in doubt because of the size and weight of tile big enough. But with the weight of 4 - 4.2 kg per unit. However, the content of the 9 - 10 units/m2 the weight of tile is light enough compared to ceramic tile. Weight of concrete roof tile is between 38-42 kg/m2, while the ceramic tile around 45 kg/m2.
There are two types of concrete roof tile, and the Centurion palace. Nova tile palace type of concrete is a product of the model large form of plate or flat. How to tile installation Nova palace this pattern, the same as brick. Enough variety of colors, namely black, brown, green, red brick, and maroon. While Centurion is a concrete tile roof tile concrete models that have curvature. This tile has a variety of colors, the maroon, green, blue, chocolate, or a combination of color are 2-3. Connection system that is used to tile type is Centurion interlock.

Concrete roof tile should have some important components, namely the tile (batten lug), water channels, double water channel, the area storm (weather checks), nail holes, side under lock, side cover lock, the body tile (roll), the bottom of the tile body (nose), and tile holder (nib support). The function of each component of concrete roof tile.

Light steel structure

The framework of light steel structure is a lightweight steel frame arrangement of the stem of a manufacturing system with assembly and calculations using the assistance of computer software. Materials used are high quality steel that is thin and lightweight. To prevent the occurrence of corrosion, the material is given galvanize or galvalum layer (layer of aluminum and zinc).
Elements of the roof structure is light steel trestle,row, and in the screw. Distance of light steel trestle, depending on the weight of the roof cover. The weight of the roof covering the distance of meeting its light steel trestle. For example by using the cover concrete tile roof, the distance between the light steel trestle can reach 1.4 m. Material thickness for light steel trestle ranged from 0.75 to 1 mm, while the thickness between 0.4 - 0.7 mm

The advantages of light steel roof structure, including:
a. Its light weight compared with the structure of the wood so that the burden should be borne by the structure under roof more.
b. Anti termite.
c. Fire-resistant.
d. It is not expand and shrink.
e. Installation faster than with wood because it is a structure of a series.

While the lack of light steel roof structure is, among others;
a. Need cover because underneath ceiling light steel structure cannot be in Expose. b. The form of the roof does not flexible like wood that is easily cut and formed.
c. Calculation of the structure must be appropriate and requires the careful supervision at the time of the error because a part of the structure will damage the other.

With the more expensive and difficult to get quality wood then use the framework of light steel roof is to be the right alternative. This is because the cost incurred for the roof structure is almost equivalent to the type of wood, depending on the model of the roof and the roof cover will be used. The more complex model of the roof and the weight of the roof will cover the greater costs.
