Light Gauge Steel House Specification
This system house can with one storey bungalow,two or three stories villa,four or five,even six
or seven stories apartment building.house area and quantity of bedrooms,bathrooms can based on
Compared with brick-concrete structure, this system house is more dynamic, and with better
thermal insulation. With different wall materials can create different architectural styles. Compared
with wooden structure, this system house is more cost-effective and most materials for this house
are environmentally friendly. In addition, because of small wall section size, the space of this house
can increase 5~8% compared with traditional structure.
Ⅱ. Technical advantages
1. Anti-seismic: Most villas use slope roofing with truss system. The roofing system will be
very strong after the truss was sealed with panels,it can against 8-degree earthquake, and has high
strength of loading capability.
2. Good Performance for against wind: light weight, high strength, good integrity, not easy
to deform, all these advantages make light gauge steel building good performance for against wind.
It can resist the cyclone at the speed of 60m/s, thus protecting the building and people’s life.
3. Durability: light gauge steel building uses cold-formed galvanized steel, thus avoiding rust
in the course of construction and use, and makes the life span of the structure 100 years.
4. Heat Preservation Performance: Heat preservation: we use glass wool as insulation and
effectively avoid the phenomenon of cold bridge of the wall body. The heat preservation effect of
100mm glass wool is equivalent to 1m-thick brick wall.

materials with the characteristics of light weight, high strength;use all kinds of new Building plate
material to decorate it,some are good insulation and fire resistance for roof,for wall and for
floors.Make the whole house are good earthquake proof, fast and easy to assemble on
site,green,and energy save,comfortable for living.

5. Fire Resistance: As the experiment data shows,use good fire proof decorate material, light
steel system can resist fire for four hours and can effectively slow down the fire spreading.
6. Sound-proof Performance: Sound-proof performance is an important item for evaluating
the accommodation. Light steel system adopt hollow glass for windows, which can soundproof for
40 db. The light steel wall system can soundproof for 60 db.
7. Healthiness: dry construction, minimum waste to the environment, and 100% recyclable of
the materials, all these advantages are conform to the consciousness of environmental protection.
What’s more, the materials we use are all green materials, which are good for people’s health.
8. Comfort: Light steel wall system adopts highly efficient energy-saving system with
respiration function to adjust the humidity of the room; with ventilation function in the roof,
ensuring the ventilation and hot scattering of the room, thus make the room more comfortable.
9. Termite resistant: The light steel buildings can completely resist termite invasion, thus
extending the life span of the house and decrease the repair cost.
10. Fast To Assemble: Dry construction and without the influence of season. A
-building only need 10 workers for 30 days from the foundation to everything finished.
11. Environmental friendly: Materials are 100% recyclable, and no pollute to the
12. Energy-Saving: Efficient and energy-saving wall has good performance on heat keeping
and sound proofing, and can achieve the energy-saving standard for 85%.
