Characteristics

High and stable quality of Jo ints

Reduce labor of

steel frame fabrication

Simplification of jo int design

Special quality control is

unnecessary .

Cuttings and welding of square-shaped steel

pipe are unnecessary.

Because there is no bracket,

transportation efficiency is obtained

Standardization of jo int details
