A range of purposely designed Ultrafloor Lintels is also available for use with the suspended flooring system or wherever else necessary. Ultrafloor Lintels are: Made of high strength concrete under strict quality control. Manufactured in four convenient sizes to suit all standard and modular bricks and are easily rendered or covered with gyprock internally. Fire rated under load in accordance with AS 1530.4-1990. Non-corrodible and thus ideal for marine and industrial exposure conditions. Able to be used in pier and beam situations for new house foundations and also for re-cladding of existing houses. Ideal for use in creating an upstand ("hob") on a concrete slab. The load charts provided in this brochure indicate the safe maximum span when Ultrafloor lintels are installed in various configurations. Construction Notes Composite Action The load carrying capacity of the Ultrafloor lintels increases significantly when they act compositely with the brickwork above. This additional strength depends on the number of brick courses applied and the tables provided in this brochure give an indication of the maximum spans in different configurations. The following instructions are important: Lintels must be placed with the rough side on top to provide a proper key to the masonry above; Lintels must be propped at intervals not exceeding 1500mm until the masonry mortar has matured. Bearing Length The minimum end bearing of the lintel on the brickwork is 100mm for spans up to 1200mm and 150mm for longer spans, based on the assumption of a minimum brick crushing strength of 20 MPa. Any abnormal loading situation should be referred to the Ultrafloor Technical Department for further advice. Installation of Hobs The lintel sections are bonded to the top of the concrete slab so as to create an upstand or "hob'' of the desired height. An edge hob is achieved by bonding the lintel flush with the slab edge as shown in the photographs. Waterproofing is achieved by extending the bitumen coating or suitable membrane up the external face of the hob.                                                                                                        Hob being bounded to slab edge Waterproofing membrane being formed Lintel being bonded to create the hob Completed hob Ultralintels Supporting Roof and Floor Example: Standard brick (110mm wide) Effective load width 2000mm 4 brick courses over lintel Maximum span 80mm high lintel -1800mm Maximum span 170mm high lintel -2100mm ULTRALINTEL SUPPORTING CONCRETE FLOOR PLUS TILE ROOF & CEILINGS Lintel type No.of brick  courses over Effective load width (mm) 1500 2000 2500 3000 4000 5000 Maximum Span of Lintel (mm) 80mm x 110mm standard lintel 0 courses 2 courses 4 courses 6 courses N/A 1200 2100 3000 N/A 900 1800 3000 N/A 900 1500 2400 N/A N/A 1500 2100 N/A N/A 1200 1800 N/A N/A 900 1500 170mm x 110mm standard lintel 0 courses 2 courses 4 courses 6 courses 1200 1500 2100 3000 1200 1200 2100 2700 1200 1200 1800 2400 1200 1200 1500 2100 900 900 1200 1800 900 900 1200 1500 90mm x 90mm modular lintel 0 courses 2 courses 4 courses 6 courses 900 1200 2100 3300 900 900 1800 3000 N/A 900 1500 2400 N/A N/A 1500 2100 N/A N/A 1200 1800 N/A N/A 900 1500 170mm x 90mm modular lintel 0 courses 2 courses 4 courses 6 courses 1200 1800 2400 3300 1200 1500 2400 3300 900 1200 1800 2400 900 1200 1500 2100 900 900 1200 1800 900 900 900 1500 ULTRALINTEL SUPPORTING TIMBER  FLOOR PLUS TILE ROOF & CEILINGS Lintel type No.of brick courses over Effective load width (mm) 1500 2000 2500 3000 4000 5000 Maximum Span of Lintel (mm) 80mm x 110mm standard lintel 0 courses 2 courses 4 courses 6 courses N/A 1500 2400 3300 N/A 1200 2400 3300 N/A 1200 2100 3000 N/A 1200 2100 3300 N/A 900 1800 2700 N/A 900 1500 2400 170mm x 110mm standard lintel 0 courses 2 courses 4 courses 6 courses 1500 1800 2700 3600 1500 1500 2400 3300 1200 1500 2400 3000 1200 1500 2100 3000 1200 1200 2100 2700 1200 1200 1800 2400 90mm x 90mm modular lintel 0 courses 2 courses 4 courses 6 courses 900 1500 2700 3600 900 1500 2400 3600 900 1200 2400 3300 900 900 1500 2100 900 900 1800 2700 N/A 900 1500 2400 170mm x 90mm modular lintel 0 courses 2 courses 4 courses 6 courses 1200 1800 3000 3900 1200 1500 3000 3900 1200 1800 2700 3600 1200 1800 2400 3300 1200 1500 2100 2700 900 1200 1800 2400 Ultralintels Supporting a Roof ULTRALINTEL SUPPORTING  TILE ROOF & CEILINGS Lintel type No.of brick courses over Effective load width (mm) 1500 2000 2500 3000 4000 5000 Maximum Span of Lintel (mm) 80mm x 110mm standard lintel 0 courses 2 courses 4 courses 6 courses 1800 2400 3900 4200 1500 2100 3600 4200 1500 2100 3300 4200 1200 1800 3300 4200 1200 1800 3300 4200 900 1500 3300 4200 170mm x 110mm standard lintel 0 courses 2 courses 4 courses 6 courses 2400 3300 4200 4200 2400 3000 4200 4200 2100 2700 4200 4200 2100 2700 3900 4200 1800 2400 3600 4200 1800 2100 3300 4200 90mm x 90mm modular lintel 0 courses 2 courses 4 courses 6 courses 2400 2400 4200 4200 2100 2400 3900 4200 1800 2100 3600 4200 1500 2100 3600 4200 1500 1800 3300 4200 1200 1800 3000 4200 170mm x 90mm modular lintel 0 courses 2 courses 4 courses 6 courses 2400 3300 4200 4200 2100 3000 4200 4200 2100 2700 4200 4200 1800 2700 4200 4200 1800 2400 3900 4200 1500 2400 3600 4200 ULTRALINTEL SUPPORTING  STEEL ROOF & CEILINGS Lintel type No.of brick courses over Effective load width (mm) 1500 2000 2500 3000 4000 5000 Maximum Span of Lintel (mm) 80mm x 110mm standard lintel 0 courses 2 courses 4 courses 6 courses 2100 2700 4200 4200 1800 2400 4200 4200 1800 2400 3900 4200 1500 2100 3900 4200 1500 2100 3600 4200 1200 1800 3300 4200 170mm x 110mm standard lintel 0 courses 2 courses 4 courses 6 courses 3000 3600 4200 4200 2700 3300 4200 4200 2400 3300 4200 4200 2400 3000 4200 4200 2100 2700 4200 4200 2100 2700 3900 4200 90mm x 90mm modular lintel 0 courses 2 courses 4 courses 6 courses 2700 3000 4200 4200 2400 2700 4200 4200 2400 2400 4200 4200 2100 2400 3900 4200 1800 2100 3600 4200 1500 2100 3600 4200 170mm x 90mm modular lintel 0 courses 2 courses 4 courses 6 courses 2700 3600 4200 4200 2400 3300 4200 4200 2400 3300 4200 4200 2100 3000 4200 4200 2100 2700 4200 4200 1800 2700 4200 4200 Ultralintels Supporting Floor Only Product Information   110 x 80mm Standard Lintel Fire Resistance Level = 60 minutes Weight = 21kg/m Bearing Lengths: spans ?
