How do I know what size lintel I need?

Measure the size of the open space between the walls where the door/window frame is fitted. Add a minimum of 150mm to each end. For example, for a structural opening or clear span of 1,800mm, the minimum lintel length required will be 1,800 + 150 + 150 = 2,100mm.

What does lintel mean in construction?

A lintel or lintol is a type of beam (a horizontal structural element) that spans openings such as portals, doors, windows and fireplaces. These prestressed concrete lintels and blocks are components that are packed together and propped to form a suspended floor concrete slab.

What’s the longest Catnic lintel you can get?

Standard lengths are available in increments of 150mm at lengths up to 3000mm, 300mm at lengths from 3000mm – 4800mm (including 4575 but excluding 4500mm).

What is a Catnic lintel?

The Catnic Thermally Broken Lintel, or TBL, is a type of thermally broken steel lintel for use in masonry cavity wall build-ups. It provides support over structural openings such as doors and windows, while minimising linear thermal bridging heat loss compared to conventional cavity lintels.

What size lintel do I need for a chimney?

Buy a concrete lintel 4″x3″x whatever length required plus some and then cut it to length (ideally using a 9″-wheel angle grinder as a 115mm wheel will not quite get through) and ensure it is long enough to be well supported each end (4″ or 6″ overlap, see next paragraph).

How thick should a lintel be?

Steel angle lintels should be at least 1/4 in. (6 mm) thick with a horizontal leg of at least 3 1/2 in. (90 mm) for use with nominal 4 in.

What is the size of lintel?

Lintel beam size:- lintel beam size specification comprise of width and depth,the width of lintel beam should be equal to width of opening, if brick wall width is 5″ then lintel width should be 5″ (125mm), 9″ thick brick wall have lintel width is 9″(225mm) and for blockwork lintel width should be 4″ to 8″.

Do Catnic lintels need DPC?

It is a National House Building Council (NHBC) requirement to apply a damp proof course (DPC) over each lintel to protect it. Many Catnic lintels feature a Duplex Corrosion Protection coating and a unique profile shape that acts as a built-in DPC.

What size Catnic lintel do I need?

The length of lintel required is calculated by establishing the total width of the structural opening and adding 150mm (200mm for CXL lintels) end bearing allowance for each end. For example, an 1800mm structural opening will require a 2100mm lintel (2200mm for CXL).

What is the best lintel?

Prestressed concrete lintels are one of the most reliable, durable and widely used in the construction industry, boasting a number of benefits including lower construction cost, fewer joints and a high strength to section ratio.

What is the standard length of a lintel?

Standard lengths are available in increments of 150mm at lengths up to 1800mm, 300mm up to 3600mm. ANG lintels should be suitably propped and laterally restrained during construction.

What does 600 | 1200 mean on a steel lintel?

As standard our steel lintels increase in length by 150mm, the two values represent the length of the lintel that the values in that column relate to. If it is 600 | 1200 it means the load span details can be applied to any lintel between 600mm and 1200mm.

Why are lintel windows only found in colonnades?

All structural openings have evolved from this system, which is seen in pure form only in colonnades and in framed structures, because the posts of doors, windows, ceilings, and roofs normally form part of the wall. The lintel must bear loads that rest on it as well as its own load without deforming or breaking.

What does UDL mean on a lintel table?

Prestressed concrete load span tables. UDL means uniformly distributed load which is measured in kiloNewtons per metre (kN/m). The principle is the same however; the higher the value, the better the load bearing capabilities on the lintel.
