1、By average product usage at 10kg per square metre, it not only facilitates workers to carry  

                                 materials, but also simplify the transportation and cost saving. 

                            3、The main beam and sub beam are connected at the same horizontal plane, which enables 

                                 the system to reach advanced stability.

                            4、Scantling timbers can be filled into the sub beam through the bottom. Then workers can

                                 nail plywood to the sub beam.

                            5、High quality cold rolled steel Q235 grade, surface treatment is finished by electrophoretic 

                                 painted of better corrosion resistance.

                            6、Replacing traditional timbers, it can be recycle- used for more than 300 times.
