Our selections of steel and concrete lintels are manufactured from superior quality material, and can be selected in accordance with your chosen parameters.
Lintels are horizontal structures that are designed to support heavy load above doors and windows. Lintels are made from a wide range of materials like timber, stone, bricks, reinforced bricks, reinforced cement concrete, and steel.
The two ends of a lintel are embedded inside the wall of the exact same width in order to transfer the load borne by the beam, of the structure above the window or door entrance, to the masonry walls. Traditionally, timber and stone, albeit with their inherent weaknesses (timber susceptible to fire and stone developing cracks under heavy vibrations) were considered the best possible options as lintel material. Although regions abundant in stones and timber continue to use lintels made of stone or timber, and brick lintels are still in use for ornate entrances with lighter load-bearing while reinforced bricks lintels are summoned for heavier loads in comparison with wider entrances, it’s lintels made from reinforced concrete and steel that have risen above the ranks and become bearers of high- standard for lintels. It must also be mentioned that reinforced brick lintels for large spans are fashioned in a manner similar to the reinforced concrete lintels by reinforcing high quality bricks with steel bars for additional strength.
Reinforced Cement Concrete Lintels are customized to cover the widest possible spans of openings and do not back away from any amount of load. Their width equals the wall’s while their depth is decided by the enormity of the load the extent of the span. Reinforced concrete lintels are reputed for being fire-resistant and highly durable, and are highly preferred for their low-priced and smooth construction.
Steel Lintels have the capacity to bear stratified layers of load which can be immensely heavy paired with really large openings in a structure. Available as rolled steel joists or steel angles, steel lintels as angles are ideal for light loading and openings that are moderately wide, while the rolled joists variety are best suited for large spans and heavy structural load. When embedded individually, steel joists are encased in either in stone or concrete. In case of multiple joists, the units are placed adjacent to each other in tube separators to maintain position.
The make of the wall and its load bearing requirement play a very important role in the selection of lintels. Cavity walls and open-back linters are a good match to service standard as well as varying grades of heavy load openings. External wall lintel assessment depends on the support required for brickwork of a single leaf or two separate leaves in brick walls with smooth finish, or box lintels with a toe in case of very thick solid brick walls. Internal wall lintels comprise of channel lintels for regular openings; box lintels for heavy loads and wide spans; and corrugated lintels for light loads and smaller spans.
