45/900 Trapezoidal Sheet

 

Type : Roof and Facede
Net Covering Width : 900 mm
Rib Height : 0.50 - 1.20 mm
Maximum Length : 16 m

45/900 trapezoidal sheets with high strength, are used as cladding material in systems with higher spans and which are subject to heavy load forces. 45/900 is ideal for facades of heavy industrial buildings and for the inner layer in sandwich membrane roofs.

table above is prepared according to allowable stress design method
yield strength of steel is taken as 220 N / nm2
table showa uniformly distrubuted load, kg/m2
moment distribution due to yielding is considered
multi-span moment: Pd*L2/11
deflection limit: L/200
