Structural Steel | ABC Pro-Series T Sections
Widely Accepted and Easy to Use with Enhanced Appearance
ABC Pro-Series T Sections are widely accepted in the building industry as supports for double brickwork above masonry openings and are readily available in a range of popular sizes. They have the advantage of eliminating the need to use two lintels in a back-to-back configuration when double brickwork is required, thus providing a stable foundation for simple brick lay up with a clean finish when viewed from below.
Building Codes and Structural Design
ABC Pro-Series T Sections have been developed to meet Australia’s building Codes. They are a structural section and do not require mortar bonding (composite action between brickwork and the section) for strength.
Protective Coating, Durability and Corrosion Resistance
ABC Pro-Series T Sections are hot-dip galvanized in accordance with the Australian Standard for Hot-dip Galvanized (zinc) coatings on ferrous articles (AS/NZS 4680:1999). The durability rating of the protective coating is R3 as described in AS/NZS 2699.3:2002 (Built-in components for masonry construction, Part 3: Lintels and shelf angles (durability requirements)
1. The minimum bearing length (or individual end bearing) must be 150mm. The T Section Length must therefore be 300mm greater than the Clear Span
2. T Sections must be propped during construction, with the prop(s) remaining in place until the mortar is fully cured.
3. Brickwork must be laid simultaneously on each side of the T Section to provide even loading and reduce the possibility of distorting the T Section and brickwork during construction.
4. The construction of all brickwork must comply with the Masonry structures standard (AS 3700-2001) and approved building practices.
5. As many structural configurations exist, a large range of sizes are produced, from which engineers and professional builders may choose, subject to appropriate certification.
