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.
