Features and services

1.firm structures and cladding

Light steel structure use efficient light thin wall material (corrugated sheet or sandwich panels).

Owing light weight ,high strength and small occupied area etc features.

2.Easy and effective production

Components are all automated, continuous, high precision production, seriation, standard product

specifications, form a complete set.All factors ensure the precision of every component.

3.Effective design and installation

Offer one-stop service from developing, design, manufacturing to installation with little mistiming.

4.Easy to assemble and disassemble

Interior decoration can be done in one time and the surface of steel structure is good for corrosion

prevision then reduce decoration fee.

5.Convenient to change and build

Increase usable area of the house,enlarge distance of pillars and supply more rooms.Easy to add

layer,reconstruct and reinforce .

6.Use new material to improve house quality

Use skylight to get sunlight and have good ventilation.

7.Environental

The house can be moved for dozend of time with plug and screw and all material can

be recycled without rubbishes.

8.Durable

The steel frame are all processed with anti-corrosion coating and can be ued fo as long

as 20-50 years.
