Structural Characteristics: It constituted of light-gauge steel members as posts and beams. The major columns take the role of vertical load bearing members while the diagonal supports resists lateral loads such as wind load and horizontal seismic force. When reinforced with concrete infill, steel members perform with a better stability in resisting compression compare to usual steel structure. The main structures are connected by bolts as continuous steel members while most of the connections considered as hinges taken in shear forces. Light-gauge steel frame as one uniform structural materials has the capability to satisfied the structural needs for ordinary dwellings, while assembled trusses can fulfill the needs for greater span.
Structural System: The structural members are cold formed from thin sheets of galvanized steel in a thickness between 1.5 to 3.0 mm. It inherited similar post and beam structural system from the Chinese traditional timber framing, with continuous structural members and a greater column spacing, allowing flexibility in the construction of walls.
Manufacture and Assembly: Steel members are cold-rolled and formed as different types of section, with advantages from steel as a very stable material in manufacturing. Steel performs great in the precision of metalworking for mass production and quality control, while the galvanized coating protects steel members against weathering. The sectional variety associated with different structural characteristics allows a big range of combinations according to different needs. Constructed by simpler fixtures like nuts and bolts, the construction process becomes much easier, faster and way more cost-effective in supervision and management.

Open Building Approach: An open framework that respects regional, cultural, socio-economical and technological conditions allowing alternations and modifications done to the built-in environment through time.
Skeleton and Infill: Open building approach is based on the concept of dividing design tasks into two different hierarchy, “support” and “infill”. Support refers to main components that are public, limited to alternation orconstant; whereas infill stands for sub-components that are privately own, diverse and compatible with changes made by time. Under the premise of RLGS, the “supports” are made with the light gauge steel framework, ensuring adequate and safe structure, while allowing various “infills” to attach such as local craftsmanship, scavenged local materials and spatialneeds.
Structure to Space: RLGS components have a handful of advantages comparing to easily-seen structure systems such as R.C. or hot-formed steel. It can be easily transported, assembled and dismantled. It requires minimum technical professionals and made with very economical materials. To respond to the needs for adjusting structure and space under the circumstance to sustain a lifespan of habitation, the system provides the inhabitants the flexibility to expand and adjust with ordinary and available techniques.
Materials Compatibility: Under different premises of the local physical environment, RLGS can be combine with material components to provide basic adequate function. At the same time, the construction must be simplified, systematized in to componentsand with the consideration of diversity. The simplification of construction process requires using readily-existed components in the market, limited the cost in developing new and special component, to allow common residents to participate in the construction process without special training. Systematized building components provides the reversibility of materials through recycle and renew partial materials for the longevity and maintenance of the building materials. The diversity of building component is established on the consideration of how to combine local materials with traditional craftsmanship with a simple and unified steel frame prototype.
