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. Nominal height – The height of the lintel in mm.
Likewise, what does the size of a lintel depend on?
Lintels are beams that span the openings for windows and external doors. The size of the lintel depends on: the width of the opening. the combination of loads being supported.
Furthermore, how thick should a lintel be? The steel for lintels, as a minimum, should comply with ASTM A 36. Steel angle lintels should be at least 1/4 in. (6 mm) thick with a horizontal leg of at least 3 1/2 in.

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).When would you use a lintel?
Lintel. A lintel is a structural horizontal support used to span an opening in a wall or between two vertical supports. It is frequently used over windows and doors, both of which represent vulnerable points in a building's structure.

The steps of RCC lintel design (single span or continuous with a few openings) are same as the design of a simple beam.- The lintel width is equal to the wall thickness.
- Consider a suitable depth of the lintel.
- Choose the effective span of the lintel ( consider reasonable end bearings and effective depth).
How do you make a BBS beam?
- Step 1 – Find cutting length of top bar. Cutting length of top bar = Clear Span of Beam + Development length (Anchorage) Ld on 2 sides – Clear Cover on 2 ends.
- Step 2 – Find cutting length of bottom bar.
- Step 3 – Find out Number of Stirrups.
- Step 4 – Find out cutting length of Each Stirrup.
