• Steel house plates the still sheet with zinc in order to supplement the weakness of corrosion.• Zinc plating is that the zinc film is covered like surface film on the steel. Even if there is a scratch, the zinc film

prevents the steel corrosion.

• Due to the anti corrosion character of zinc plating, it is widely used in manufacturing the industrial product such as, automobile,

signage, heavy pipe, household goods etc.

• The steel plate and material for steel house are high quality products to satisfy the z180, which is the standard for American steel

associate and the steel house built with zinc plated material will have a permanent life span.

Durability

It can function as a house to comfort the residents like old clothes which you have worn for a long time maintaininghigh standard just like new one.

Durability

In wooden house, there is a case that the house was decayed, shrunken, twisted or damaged by mouse or harmfulinsect. But Steel house has a superior durability and safety for fire since it fixes the structure directly into the concretefoundation with cold steel plate of zinc galvanizing.

It has a long life span and solid feature. It can build the house which is solid and safe to the disaster and transferred tothe next three generation for a 100 years.

Superior Performance

Though the wall itself is thin, it has a superior noise block effect by utilizing the various finishing product. So they are ableto build quiet and comfortable house. As a matter of fact in advanced country it is already used to build the hospital ordormitory and proved the superior performance.

When building with same surface insulation material, the thickness of Steel house is quite thinner than other house andshows the superior insulation effect. It can maintain the comfortable indoor environment even in the wet climate and there isno smell that you saw in concrete building.



-


Since it uses the dry wall construction method rather than wet wall construction like concrete which takes a lot of time,

you can finish building the house faster than existing house (In building 720 square feet house, 7days). So it is very cost


e ective.

Since it uses the assembly method using steel stud, it is easier for general worker to handle. Therefore there is a big costsaving effect.

There is no need or heavy equipment since a materia is ight weighted. A so it can be easi y bui d since it connects thestructural material with tapping screw using the electric equipment.

There is no need to worry about the construction defect with quality standard steel material. The construction cost can belowered with mass production, self supply and technology development.

It is easy to cope with construction defect and the electrical, plumbing work is simple.

Thinking the convenience to remodel and expand, recycling and long life span, it is really economical.

Environment Friendly

Zinc galvanizing steel material used in Steel house can be recycled. And it can be used as a house building material.

Considering the 1800 sq ft house as a standard, Steel house can use recycled steel of 6 truck load in order to secure the

material but the wooden house needs about 40-50 trees with 30 or more years

Outline

For the past 100 years, Zinc has been contributing in improving life span and durability of steel materials.

Outline

Zinc is the most effective and economic way to protect steels. Melton galvanized steel sheet not only shows

excellent corrosion resistance, but is also great in processability, welding & coating quality and recycling. Since

it is light and beautiful, its usage is expanded to car maker, furniture and other various aspects not to mention

the construction and civil engineering fields. Recently, with the fast distribution of steel house globally, the

market also expanded to roof material.

Example of Zinc galvanized steelApplied fields and conditions of Zinc galvanizationpplied fields and conditions of Zinc galvanization





Durability of Zinc galvanized lightweight shape structure

Durability of Zinc galvanized materials has close relationship with the materials in the air and period

exposed to humidity. In case of steel house, low internal humidity slows down the corrosion rate of the

materials. In conclusion, the life span of the steel house is almost permanent when lightweight shape structure

is used recommended by the American Iron and Steel Institute. Like most of the construction materials, Zinc

galvanized materials will be corroded when exposed to leakage, excessive humidity, and condensation.

However, there is no need to worry about condensation if steel house is built with quality insulation according

to construction regulation and ventilated and maintained properly. Steel houses by the shore shall require

additional late.

Quality in Steel House

The corrosion rate of the Zinc galvanized steels is generally very slow inside the house. According to the

research conducted in Technical-Welsh Laboratories of British Steel for 3 years, less than 0.1um corrosion rate

was shown on the average in the 15 houses in various places in city, suburban and industrial area. This test tells

galvanization. On top of that, in May 1995, a corrosion test was run on a 20-year old steel house in Stoney Creek,

Ontario, Canada, clear evidence of corrosion on Zinc galvanized STUD (Vertical column) was not found. And

t ere was a most no amage to t e coat ng on t e o t e externa an nterna wa s.





Conclusiononclusion

The corrosion can be effectively and economically prevented when drew lightweight shape and Melton

galvanized steel sheet was used as main material of the buildings including steel houses. Zinc galvanization

forms hard zinc layer on the surface of material and this prevents corrosion problems in the process of

material production, transportation, storage and construction stage. The steel materials in steel house are used

mostly on the floors, walls, or roof and this also slows down the rate of corrosion of Zinc.

The steel house with lightweight shape structure will be the optimal residential facility for Brunei where the

The lightweight shape structure used by GTC Corporation is almost permanent since the quantity of plate

.

used is more than that of the ones suggested by the American Iron and Steel Institute.

4-2 Earthquake Resistance (1)




There are many causes when a building is destructed or collapsed by earthquake. Because a direct damage

to building is a natural phenomenon of earthquake. The natural phenomenon caused by earthquake are shaking

of ground, landslide, avalanche, rise and split of ground and Tsunami and so on. All these can influence a house

variously, but in order to evaluate safety of a house against earthquake, damage of the building caused by the

horizontal force created by the vibration of the ground shall be tested as in the exhibit 1. Thus, safety of abuilding against earthquake correlates closely with the solidity of joints enduring the weight of the building.

Firstly, earthquake moves the weight of the building

horizontally and the horizontal force varies from time to

. .

The horizontal movement is proportional to the weight of

the building. That is, the lighter the building, the less the

and a piece of steel house wall weighs 1/8 of a concretewall and half of 2x4 wooden wall same size. That is why

지진동the steel house is much safer with less horizontal

movement when same size and floors of houses were hit

by earthquake.

Exhibit 1. Movement of weight caused by earthquake





The horizontal weight movement starts from base ground to walls and on to floors and to the walls on 2nd

floor and up to the roof. One part that can not endure the weight movement, the building gets damage. The

base ground, walls, floors and roofs of steel house can be planned to resist strongly against horizontal weight

movement Firstly, a steel structure called Hold-down is installed to prevent weight movement transiting from

ground to walls, and then anchor connects walls and ground to avoid slipping of walls by the weightmovement. (Exhibit 2)

The walls of steel house uses X-bracing or sheathing materials to keep the walls

from transforming to diamond shape by weight movement as in the exhibit 3. X-

bracing are made of steel sheet to maximize resistance even when installed in small

places. On the other hand, sheathing material shows weak resistance comparing to

X-bracing, but can be installed in larger area.

Exhibit 2: Picture of Hold-down and Anchor Exhibit 3: Steel house walls resisting against weight movement





X-bracing uses the same steel sheet as in the steel house materials and depending on the width, thickness

and number of screws in corner joints, resistance power can be controlled against weight movement. Thus this

is effective when the building has light walls or weight movement is great. (Exhibit 4)

In case of steel house floor, a structural material called Joist with 18mm OSB is used or tightening of

screws by Deck-plate and then connects with blocking and strap. A floor built this way can resist against

horizontal weight movement from walls. (Exhibit 5)

4 2 Earthquake Resistance (5)

In case of steel house roof, a structural materials called Truss is assembled and then connected with 12mm

OSB screw. They are connected by Truss bracing to resist against horizontal weight movement. Truss and

walls are connected with screws and steel connector. This construction method, used in the steel house walls,

has been proved safe through hold-down installation, anchor installation, plaster board, number of screws

.

and it was hit by an actual seismic wave (El Centro wave, Kobe EW wave) to prove the safety.
