 Built to Last

What is a Concrete Lintel?

A concrete lintel is a horizontal non-structural support element placed above doors, windows, or other openings. Being a NON-STRUCTURAL element, lintels should not be used to bear the weight of the brickwork alone but by laying at least 4 courses of bricks and mortar with brick force in between each course. A beam is formed above an opening which is much stronger than the brickwork or lintel alone. The span should be propped for a minimum of 28 days to allow for sufficient strength to prevent the lintel from sagging

CIK Concrete lintels are pre-stressed and reinforced with high-tensile steel wires, making them strong, durable, and dependable — essential for any building project.
