Light Steel ZAFIR TRUSS is steel roof truss structural system constraint without purlins rafters dn. Which is directly combined with battens so that the process work faster and precision. ZAFIR TRUSS made of aluminum coated steel (zincalume) with AZ 100 (100g / m2) and also material galvanized Z220 (220gr / m2) has a tensile stress of 550 MPa and melting (G550) that have consistent material quality, not brittle and resistant against corrosion.
