Prestressed Structural Lintels
Conventional lintels are mistakenly assumed to be structural beams, but in fact it has very little strength. Developed only as temporary formwork to aid the builder in bricklaying, it combines with the brickwork to form a beam. Without the brickwork it cannot be expected to act as a beam, hence it is placed over an opening, propped, and once the new brickwork has set, the props are removed.
Now BASS BEAMS has developed a special Lintel which is structurally a beam and needs no propping. Openings of up to 8m can be bricked over these giant lintels whereas conventional lintels are restricted normally to 3m.
Reinforced Concrete Beams
Structural Reinforced Concrete Beams
Additional strengths can be provided with custom designed precast beams. Conventional reinforced concrete beams using Y-bars and stirrups can be custom manufactured to engineers design and specification in addition to the stock sizes, as per graph. These are ex-factory, delivered and erected on site in conjunction with a Bass Beams Slab or ex-factory as single orders.

Structural Steel Beams
For difficult applications, where concrete beams are not suitable, steel beams such as Angle Iron, I-Beams and Channel Iron, can be obtained to engineers specifications. Bass Beams' T-Beam propless slabs and flat soffit are readily adapted for the usage in conjunction with structural steel I-Beams as support beams / lintels.
