T Bar

Fields of application For general use and for use in the household, welded metallic construction elements or construction elements joint through other methods, agricultural works. Aspects In sections, the axis of the crossing must be perpendicular on the axis of the angles. The limit deviation from the perpendicularity of the crossing must be lower or maximum equal with 1mm. In section, the angles must be equal. The bars must be straight, without bends or strains of the axis. The deviation from rectilinearity should not surpass 6 mm/m. It is not admitted any visible twist of the section around its own axis. The sections must be cut without the bending of the endings and without the visible strain of the section. The burrs resulting form cutting must not surpass 5 mm. Delivery conditions The T steel with equal angles is delivered in rolled state, in links between 50-3000kg.
