1. High strength and durability.
Unlike wood, steel is not affected by biological processes (e. g., rotting). The service life of light gauge steel framings exceeds 100 years. They can withstand all the features of our climate: temperature changes, precipitation, winds.
2. Fast construction.
In contrast to buildings from traditional materials, comfortable villages composed of steel frame houses can be constructed within a month. Frame houses that use prefabricated parts are lightweight, which in most cases eliminates the need for lifting mechanisms.
3. Independence from weather conditions.
Customers are not limited by weather conditions in the course of the construction of frame housing using the prefab house.
Due to the absence of wet processes in their construction, the construction team can provide a continuous workflow.
4. Low cost.
The final cost of a frame house constructed with the prefab house is lower than that of a house from traditional building materials: bricks, concrete blocks, conventional bricks, etc.
5. High resistance to heat loss.
High thermal insulation properties of the building are provided by the fact that, unlike that of the buildings made of brick or wood, the entire thickness of the wall is filled with a highly efficient heat-insulating material, which can significantly reduce the heating costs of the building.
6. Earthquake and fire safety.
prefab houses can withstand seismic loads of up to 8.0 on the Richter scale. Mineral wool which is used as an insulation material can be used at a wide range of temperatures (from -60 oC to +400 oC). Thus, the structures do not accumulate moisture, are protected against corrosive acidic environment, high temperatures and fire, and are not susceptible to rodent and microorganism infestation.
The steel components of the prefab house can be reused, which is a big environmentally-friendly advantage. This advantage is also actively leveraged by extractive industries in rotational camp construction.
8. No shrinkage.
Due to their lightness, prefab houses are not subject to shrinkage observed in the construction of brick and aerated concrete houses.
9. Wide architectural possibilities.
Prefab house may cover large bays of up to 20 m without intermediate supports. This allows for the best use of the buildings internal space as well as for the re-planning possibilities.

2. Detailed Description
Primary Framing Elements-columns, beams and all primary members are made by H section steels- hot rolled section steel/ welded section steel, which will be bolted together at the site. A factory primer and facing paintings are applied to get the better anti-rusting effect of primary framing elements.
Secondary Framing-Purlin, Tie Bar, Roof, and Wall Support are formed as secondary framing
1 – Roofing system: It blocks rain, snow, and wind. Ensure a comfortable and dry working environment in the workshop/warehouse.
2 - Composite floor deck: A two-story or multi-story building, which is poured on the floor slab to serve as a formwork. Save time and improve construction progress.
3 - Hallway system: We can provide various wall partitions of different materials.
4 – Purlin: Support the roof sheeting and the fixed position of the roof sheeting.
5 – Finished metal siding and flashing: Roof and Wall are covering of color-coated corrugated steel sheet or steel sandwich panel, hot dipped with zinc and aluminum compound, that is fixed to the outside of the structural building to protect it against bad weather or to make it look more attractive and last for generations.
6 - Painted Roll – Up doors and filler panels: Easy access. According to customer requirements, there are composite panel doors, electric shutter doors and so on.
7 – Support post: Supporting building.
8 - Load bearing wall assembly with horizontal partitions for shear walls: Supporting building.

3. Steel Structure Process
3.1 Prepare raw materials
Cut steel plate or use customized size H section steel and angle steel, round tube, round steel, square tube, etc.;
3.2 Assembly and welding
Our welders will follow the drawings to assemble the steel members and weld them together as an entire beam/column/brace and so on; (Our quality inspector will check the steel pieces after finish welding, this is the first quality check)
After finish welding and polishing, our sandblast effect can reach internation 2.5 high grade, very good for resisting rust; (Secondary quality check)
Within 2 hours after sandblasting, all the steel members should be painted. A client can choose any color and any brand of paint. (The third quality check)
