Concrete lintels are reinforced beams used to support loads above doorways and windows in masonry walls. They help distribute weight evenly across openings. Naylor concrete lintels are a reliable, high-performance option for a wide range of construction projects.

Their strength, durability, and load-bearing capacity make them an essential component for any build.

Are Concrete Lintels Stronger Than Steel Lintels?

Both concrete and steel lintels have unique advantages. Concrete lintels excel in compressive strength, fire resistance, and corrosion protection. They're often more cost-effective for shorter spans and perform well in most environments.

Steel lintels, on the other hand, offer higher tensile strength and are ideal for longer spans. Their lighter weight can also simplify installation. Choosing between the two depends on the specific structural requirements of your project.

What’s the Difference Between Precast and Traditional Concrete Lintels?

• Manufacturing: Precast lintels are made in factories under controlled conditions; traditional ones are poured on-site.
• Quality control: Precast lintels offer more consistent strength and quality. Site-cast lintels may vary depending on environmental factors.
• Installation time: Precast options are ready to install, saving time. Traditional lintels require curing before use.
• Customisation: Traditional lintels allow for more on-site adjustments, while precast options come in set sizes.
• Strength: Controlled curing in precast production typically results in higher strength and durability.

What Size Concrete Lintel Do I Need?

The right lintel size depends on factors like the width of the opening, the thickness of the wall, and the load above it. You’ll need to account for both dead loads (wall material) and live loads (floors, roofs, etc.).

As a rule of thumb, standard lintel lengths range from 600mm to 3600mm, with depths between 65mm and 215mm. Always refer to local building codes and ensure the lintel is rated to exceed your load requirements for safety.

5 Expert Tips for Installing Concrete Lintels

• Use proper support: Prop the lintel securely during installation and curing. Use adjustable supports spaced every 600mm on a firm, level base.
• Create a level mortar bed: Apply an even bed of mortar and check with a spirit level. This ensures the lintel sits flat and avoids stress points.
• Ensure minimum bearing: Provide at least 150mm of bearing at each end. For heavier loads, increase to 200mm or more.
• Keep temporary props in place: Leave supports for at least 7 days or until the mortar has cured, especially in cold weather.
• Protect from the weather: Use sheeting to cover lintels during curing to shield them from rain and temperature fluctuations.
