Steel Lintels & Mansonry Building Products
Compliance for Inclusion in Masonry Structures
ABC Pro-Series Lintels, Gal Flat Bar and T Sections comply with the Masonry structures standard (AS 3700:2001) and Masonry in small buildings Parts 1 & 2 (AS 4773.1 & AS 4773.2:2010) concerning steel Lintels supporting brickwork over openings. ABC Pro-Series Lintels and T Sections have been designed specifically for this purpose and should not be used for other applications unless appropriate evaluations show that they are capable of performing the tasks required for those applications.
Protective Coating, Durability and Corrosion Resistance
ABC Pro-Series Lintels, Gal Flat Bar and T Sections are hot-dip galvanized in accordance with the Australian Standard for Hot-dip Galvanized (zinc) coatings on fabricated ferrous articles (AS/NZS 4680:2006). The impact resistance of the galvanized coating complies with AS/NZS 2699.3:2002 (Built-in components for masonry construc- tion, Part 3: Lintels and shelf angles (durability requirements)). The durability rating of the protective coating is R3 as described in AS/NZS 2699.3:2002 and all ABC Pro-Series Lintels, Gal Flat Bar and T Sections are marked as demanded by Section 4 of this standard. If required, a corrosion resistance rating of R4 (for galvanized duplex- coated lintels) can be achieved by applying a paint coating over the galvanized finish, as detailed in AS/NZS 2699.3:2002. Note that to meet the durability requirements for severe marine environments, as described in section 5 of the Masonry structures standard (AS 3700:2001), a corrosion resistance rating of R4 must be achieved.
Structural Integrity and Load-Bearing Capacity
The load-bearing capacity of ABC Pro-Series Lintels was determined in line with industry practice and by reference to Australian Standards. The loads used in the preparation of the Selection Guide were in accordance with AS/NZS 1170.1:1989 and AS/NZS 1170.2:1989.
The Selection Guide that covers Lintels supporting roof and/or brickwork loads that are encountered in residential structures in installation types A, B and C as defined in AS 3700:2001. As many other structural configurations exist, a large range of sizes are produced, from which engineers and professional builders may choose, subject to appropriate certification.
