Masonry Lintels Vs Steel Lintels: Why Contractors Prefer Masonry
Masonry lintels, including those made from timber, stone, brick, and reinforced brick, are preferred by contractors over steel lintels for several reasons. One notable advantage of masonry lintels is their fast and easy installation process. Contractors find it quicker and simpler to install masonry lintels compared to steel lintels. This not only saves time but also reduces costs and lead times associated with construction.
Another significant benefit of masonry lintels is their ability to prevent cracks at bearing points. Steel lintels often cause cracks where they bear the weight of the structure, but masonry lintels, with their durable and solid construction, solve this issue. They can withstand heavy loads without causing any structural damage, making them a more reliable choice for contractors.
Advantages Of Masonry Lintels: Faster Installation, Lower Costs, And Reduced Lead Times
When it comes to construction projects, time and cost-efficiency are crucial factors. Masonry lintels excel in both areas. Their faster installation process results in reduced labor costs and shorter lead times. By opting for masonry lintels, contractors can complete projects more quickly, allowing for faster occupancy or use of the building.
Furthermore, masonry lintels offer cost savings in materials and maintenance. Compared to steel lintels, which require additional protective coatings and regular maintenance to prevent corrosion, masonry lintels have enhanced durability. They do not require the same level of maintenance, thereby reducing long-term costs for the building owner.
In addition to these benefits, masonry lintels provide aesthetic appeal, especially when made from materials like stone or brick. They blend seamlessly with the overall masonry construction, enhancing the visual appeal of the building while providing structural stability.
Eliminating Cracking Potential: How Masonry Lintels Outperform Steel Lintels
One of the significant issues with steel lintels is the tendency to crack at bearing points. This occurs due to the high stresses and strains exerted on the steel lintel as it supports the weight of the structure above it.
On the other hand, masonry lintels have the advantage of distributing the load more evenly, reducing the concentration of stress at specific points. The solid and robust nature of masonry materials, such as brick and stone, ensures that the lintel can withstand heavy loads without cracking.
Moreover, the use of temporary supports during the construction phase prevents any potential damage to masonry lintels. These supports, which can be provided by using wood or inverted steel angles, hold the lintels in place until they are reinforced by bond beam CMU units. Once the temporary supports are removed, the masonry lintels are fully capable of bearing the load without any cracking or structural issues.
