Rock Lintel
Rectangle-shaped little bits of rock can be made use of as a lintel. This sort of lintel is mostly made use of around where the stone is well easily accessible. On the off chance that the size of the opening is long, by then, nevertheless, two bits of lumber are joined to give the lintel all points taken into consideration openings. They are merely utilized in mountainous structures as they evaluate excessively, as well as due to the non-availability of various other materials for their building. Its usage is inherently bound to stone masonry structures. Stone lintels need to be utilized according to an understanding of the particular layering. The density of the rock lintel is a significant variable for its layout. As a thumb regulation, the density is taken as 4 cm. Per 30 cm length of span and the minimal thickness needs to be 8 cm. This kind of lintel will certainly be firm as well as strong. There are a few inconveniences likewise of the stone lintel.
Strengthened Concrete Lintel
Currently, strengthened concrete lintels are extremely common in operation. In this kind, reinforcement is utilized to overcome the reduced malleable issue in concrete. They are established in present-day structures. They are also appropriate for heavy loads and bigger periods. Their density is maintained around as much as 8 centimeters for each meter. RCC lintels can be either precast or cast-in-situ. Generally, precast strengthened cement concrete lintels are made use of when the lintel span is smaller. Lintel width should be the same as wall surface width. The deepness of the lintel relies on the length of the span and the loading’s size.
Steel Lintels

It includes rolled steel joists or channel areas, either used singly or in the mix of two or three systems.
Brick Lintels.
Brick lintels are built with tough, well-charred superior brick. It can be developed as bricks on end, bricks on edge and flowed bricks laid horizontally over openings. This type of lintel is utilized when the opening is small (less than 1 m) with light loading. Their deepness varies from 10 centimeters (thickness of one brick) to 20 cm, relying on the span. Blocks with frogs loaded with mortar offer more shear resistance at end joints than the criterion blocks.
