STEEL BUILDING SYSTEMS

• Types of Building Systems
• Rigid Frame
• Beam and Column
• Truss Frame
• Self-framing

STEEL BUILDING SYSTEMS

• Rigid Frame
• clear span rigid frames
• rafters (tapered or uniform depth) rigidly
  connected to columns
• rigid frames spaced on predetermined bay lengths
• rigid frames support secondary structural
  members and cladding
• Beam and Column
• tapered or uniform depth beams or girders
  supported by columns
• primary beams / girders
• span the width of the building
• spaced on predetermined bay lengths
• support the secondary structural members and
  cladding

STEEL BUILDING SYSTEMS

• Truss Frame
• variable or uniform depth braced trusses
  supported by columns
• primary trusses
• span the width of the building
• spaced on predetermined bay lengths
• support the secondary structural members and
  cladding
• Self Framing
• cladding as primary load bearing roof and wall
  elements
• cladding functions as weather barrier

LGS PRODUCT FOR STEEL HOUSES

• Benefits to the Builder
• LGS is lightweight, which makes construction
  easier.No use of heavy construction equipment
• Consistent quality of LGS components reduces job
  site wastage.LGS components can be supplied to
  exact lengths sizes,
• Steel wall panels and floor decking provide good
  sound insulation and fire resistance based on
  design applications.
• Quick erection time implies saving to builders,
  developer, or building owner thru reduced
  financing costs.
• Dead load Live load. Steel 5050. Concrete
  7030
