Bass Beams has developed a large special Lintel which is structurally a beam and needs no propping.
Openings of up to 8m can be bricked over these giant lintels.
Key Benefits
- Cost Effective
- High Quality – SABS standards
- Manufactured in a controlled factory environment
- Convenient
- Quick erection and easy installation
- Dry installation
- No shuttering required
- No propping required
- Unsupported spans of up to 8.5m
- Domestic, commercial and industrial loading capacity
- Adaptable to meet engineers requirements / specifications.
Structural Reinforced Concrete Lintels
Additional strengths can be provided with custom designed precast lintels. Conventional reinforced concrete lintels using Y-bars and stirrups can be custom manufactured to Engineers design and specification in addition to the stock sizes, as per graph. Bass Beams Lintels Type 1645 and 2547 are to be installed rough side up with a minimum bearing of 200mm either side. (Not applicable to standard Lintels.) These giant Lintels are delivered and erected on site in conjunction with a Bass Beams slab or available 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’ propless T-Beam and Flat soffit beams (Flat Ceiling Slab) are readily adapted for the usage in conjunction with structural steel
I-Beams as support beams / lintels.
Conventional Lintels
Conventional lintels are mistakenly assumed to be structural beams. However, it has very little strength and is restricted to 3.0m spans. Developed only as temporary form-work 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.
