What kind of lintel is a lintel made of?
Lintels. Our products are constructed with a unique duplex corrosion protection system, an integral plaster key, a built-in damp proof course, and continuous insulation to make them the most distinctive lintel on the market. Catnic has been a pioneer of steel lintels for five generations.
How long is a standard Lintol?
It will be twice the length of a half-length. Seriously, the longest regular lintol available is 4.8m in length. You can have them longer if you have them designed and engineered properly; I believe they are 6m wall to wall.
How long can you get a lintel?
Both 100mm wide and 200-215mm wide box lintels are offered to support 100mm wide walls with lengths ranging from 1200 to 3600mm and 200-215mm wide walls with lengths ranging from 1200 to 4800mm.
How far can a steel lintel span?
Steel angle lintels can be utilized for openings up to 8 ft 0 in in most cases, according to building codes (2.4 m). Lintels that are fire resistant are often required for openings that are bigger than this.
How much overhang should a Catnic lintel have?
Each focused load must be supported by a lintel that is no less than 200mm in length to be effective. Point loads applied directly to the flanges of lintels should also be avoided whenever possible. Furthermore, if the lintel supports an external cavity wall, the outer leaf shall not bear more than half of the maximum safe working load.
How far should a lintel extend?
Ideally, each focused load should be supported by a lintel that is at least 200mm in length. Furthermore, it is recommended that point loads not be applied directly to the corners of lintels. Furthermore, in cases where the lintel supports an external cavity wall, the outer leaf should not bear more than half of the maximum safe working load.
What is a Catnic lintel used for?
Box lintels are a versatile kind of structural support that may be simply coursed in with ordinary masonry units in solid exterior walls, masonry cavity walls, and interior walls. Box lintels are available in a variety of sizes and shapes.
Are Catnic lintels load bearing?
The design of each lintel is intended to support a particular safe working load (SWL). You should seek guidance from Catnic Technical Services if you are not familiar with the load assessment process or if you have not been provided with a load by a third party. Their phone number is 02920 337900.
What is a Catnic lintel?
The Catnic Thermally Broken Lintel, often known as the TBL, is a form of thermally broken steel lintel that is used in the construction of masonry cavity walls. Comparing to traditional cavity lintels, it offers support above structural openings such as doors and windows while decreasing linear thermal bridging heat loss as a result of the thermal transfer between them.
Which type of lintel is used for higher spans?
Lintel made of reinforced concrete They are excellent for heavier loads as well as for longer spanning distances. Their thickness is restricted to a maximum of 8 millimeters per meter for each meter of length. Lintels made of RCC can be either precast or cast-in-place. Precast reinforced cement concrete lintels are often employed when the span between the lintels is less than six feet.
Do lintels need Padstones?
One of the most important things to do is to bedding the lintel with mortar and leveling it both along the lintel’s length and across its breadth. Bearing areas should be constructed out of whole bricks, blocks, or padstones.
What overhang do I need on a lintel?
The location of a lintel within a hollow wall The masonry should not protrude more than 25mm beyond any flanges.
Can you cut Catnic lintels?
Is it possible to cut Catnic lintel? The Catnic products cannot be cut, in contrast to steel lintel beams, which may be cut. This is due to the fact that they have a strengthened end, which if removed will cause the beam’s integrity to be compromised. The outcome of this is that Catnic strongly advises that their beams should not be cut under any circumstances.
How much should a lintel overlap?
All lintels must be at least 150mm thick.
What is the longest concrete lintel?
Concrete lintels are available in a variety of lengths, including 600mm, 900mm, 1200mm, 1350mm, 1500mm, and 1800mm. They are also available in a variety of widths. Lintels that are made to order are available.
How wide does a lintel have to be?
When the width of the opening is greater than 3.6m, a rolled steel lintel is frequently necessary. In order to accommodate a 150mm bearing on both sides of the opening, the lintel length will need to be 300mm longer than the opening width. Bearings of 100mm on each side would be required for widths less than a metre in length and breadth.
Do lintels need to be fire rated?
A fire prevention system must be installed on the exposed faces of lintels. Unless demonstrated otherwise by a structural engineer, avoid placing point loads right above a lintel.
What lengths do CTJ lintels come in?
From 1500mm to 3000mm, standard lengths may be ordered in increments of 150mm and 300mm at lengths ranging from 3000mm to 4800mm, respectively (including 4575mm, but excluding 4500mm).Outer Leaf: 102mm * CTJ lintels are available in a variety of cavity widths; for further information, please contact our Technical Department at 029 2033 7900.Duty at a Standard Rate Duty at a Standard Rate Propping on a Standard Duty 35
