Search by wall type and loading condition, among other options, to see relevant search results and explore the performance characteristics of each lintel.įor detailed technical support or to discuss non-standard steel lintel solutions for other solid wall build-ups, contact us to discuss your requirements. Use the Catnic lintel product selector to start the specification process and help find the right lintels for your project. A central plate, perpendicular to the centre of the lintel’s base, gives the lintel rigidity and sits in the centre of the wall construction between the two masonry skins. Inverted T lintels are exactly what they sound like, comprising a base plate that spans the complete wall thickness and supports the masonry. If thermal insulation is to be part of the wall construction, then a box lintel can feature integral insulation to help reduce the impact of the steel on the overall heat loss through the wall. A projecting toe sits across the outer ‘skin’, supporting that part of the wall build-up. Catnic offers two types of steel lintel for external solid walls, and both ranges include options for standard duty and heavy duty loading conditions.īox lintels feature a hollow rectangular profile, which is installed as part of the inner ‘skin’ of masonry. What type of lintels are available for solid walls?Īs well as the wall construction, lintel specification is determined by the size of the opening the lintel has to span and the load imposed by the structure above. Catnic distinguishes between external solid walls and internal walls, with a separate range of internal wall lintels available. In some cases, the term ‘solid wall’ is also used for load-bearing masonry walls of 75mm to 100mm thick. Alternatively, where a rendered or cladding finish is desired, the whole wall can be constructed using concrete blocks. Where pre-stressed and reinforced concrete lintels are used: For concrete lintels, the lintel must be built in with the reinforcement in the correct orientation. A solid wall can be constructed entirely from brick, stone, or with a concrete inner and a brick outer face. The make-up of the solid wall depends on the desired external finish. Once you have chosen the correct lintel for your project, it is crucial that the lintel be installed properly if it is not, it could lead to serious issues. Unlike a masonry cavity wall, a solid wall has no meaningful air space between the two masonry ‘skins’. What is a solid wall?Ī typical external solid wall is around 200mm to 215mm thick, being a double thickness of ‘standard’ brick and/or concrete block masonry. Steel is the ideal lintel material for solid walls, being strong enough and versatile enough to create products that sit unobtrusively within the wall build-up while supporting the entire thickness of the construction over structural openings. Wait at least 24 hours before proceeding.External solid wall constructions vary in their thickness and make-up, featuring brick, concrete block or a combination of the two. A bed of mortar should be applied to the top of the lintel and a bed of mortar should be placed onto the bearing points, you can now position the lintel, ensure it is Level.

The new lintel must project at least 6 inches beyond the intended opening! Reinforced concrete lintels are normally used for internal openings, It might be necessary to remove a further course of bricks below where the lintel is to be positioned to enable the new lintel to be positioned correctly. Of these, though, the only materi-al that matches the appearance of masonry is masonry itself. Wood, stone, steel, concrete, brick, and block all have been used as lintels in masonry walls. After removing the bricks you can install the new lintel, if you have any doubts about the strength of the masonry it is a good idea to use engineering bricks for the bearing points. The solu-tion was the lintel, a beam that spans from one side of the win-dow to the other.

Using a masonry bit and power drill, remove all the mortar from between the joints by drilling it away and moving the drill from side to side.ģ. using a 9 inch angle grinder and diamond tipped disk cut away the mortar which surrounds the bricks, this will create lots of dust and can only really be done in the early stages of a complete refurbishment project.Ģ. When the props are secure you can carefully remove the bricks which need removing for the lintel, there are several ways in which you can do this-ġ.
