The economical span lengths of the pitched roof trusses,excluding the Mansard trusses,range from 6 m to 12 m.The Mansard trusses can be used in the span ranges of 12 m to 30 m.3.2 Parallel Chord Trusses The parallel chord trusses are used to support North Light roof trusses in industrial buildings as well as in intermediate span bridges.APPENDIX C SPAN TABLES - Australian Steel Institutedesign aspects for construction composite steel framed structures 54 Table C.1 - Office floors.Standard Offices Q = 3 + 1.5 Premium Grade Offices Q = 4 + 1.5 Span Spacing Beam Camber Nos studs Nat.Fn Beam Camber Nos studs Nat.Fn (m) (m) 300PLUS (mm) per beam Hz 300PLUS (mm) per beam Hz Secondary Beams 8 2.8 310UB40.4 30 21 6.4 310UB40.4 Cold-Formed Steel L Header Field Guidethe maximum allowable span for the double L-headers due to uplift loads.The uplift span tables provided are applicable for the top floor of a two-story build-ing or for a one-story building.Uplift loads were found negligible for the bot-tom floor of a two-story building and therefore,no uplift span

weight of the HSS beam.Example 2 Select the lightest 8-inch deep,simply supported ERW HSS beam of Fy = 50 ksi (ASTM A500 Gr.C) to span 8 feet and support a maximum factored uniform load of 52 kips (includes the estimated weight of the HSS beam).The beam is laterally supported for its entire length.Prefabricated Steel Buildings By Ezybuild Tata BlueScope These steel trusses are made from lightweight high strength steel which provides inner strength to protect and maintain the roofs structural integrity and quality of construction.The steel truss members are made from ZINCALUME&steel,a 100% recyclable andRMC Structural Lightweight Concrete - India's first Oct 11,2018·As a result,Structural Lightweight Concrete can be used extensively in top floors of high rise construction,long span bridges,steel structures,marine structures,screeds among others.In fact,owing to its low density,durability,longevity,and freeze and thaw resistance,it was even used in the construction of ships during World War I and II.

Our frames are made from very strong,hight tensile,long span galvanised steel.Sustainable Our steels two main ingredients are iron and recycled steel. Their light weight and large spans make them a popular choice for builders when constructing new homes and additions. SteelMAX Building Systems TM PO BOX 5040 Maroochydore BC 4558
