Precast Reinforced Concrete Lintels

PRECAST REINFORCED CONCRETE LINTEL

General Introduction

HAN precast reinforced concrete lintel is a beam-shaped structural component manufactured at the factory for installation above doors, windows and other openings in masonry walls.

The product is manufactured from high-grade fiber-reinforced concrete combined with load-bearing steel reinforcement, providing rigidity, load-bearing capacity and stability during use.

Using precast lintels reduces the need for on-site formwork installation, steel reinforcement placement and concrete casting. This helps shorten construction time, minimize material waste and improve the consistency of masonry work.

Features of HAN Precast Reinforced Concrete Lintels

Classification of Precast Reinforced Concrete Lintels

Depending on the requirements of each project, HAN precast reinforced concrete lintels can be classified according to the following criteria:

• By length: Products are available in standard lengths or can be manufactured upon request.
• By load-bearing capacity: Products are selected according to the load of the masonry above the opening.
• By application: Suitable for doors, windows, ventilation openings and other openings in masonry walls.
• By design requirements: Dimensions and steel reinforcement configurations can be adjusted according to the project’s technical drawings.

Manufacturing Materials

HAN precast reinforced concrete lintels are manufactured from high-grade fiber-reinforced concrete combined with an internal load-bearing steel reinforcement system.

The combination of concrete, reinforcing fibers and steel reinforcement provides the rigidity, load-bearing capacity and stability required for installation above doors, windows and other openings in masonry walls.

Advantages of Precast Concrete Lintels

• Factory manufacturing ensures consistent product quality and dimensions.
• Reduces on-site steel reinforcement fabrication, formwork installation and concrete casting.
• Shortens the construction time required for masonry work.
• Minimizes material waste and reduces on-site workload.
• Easy to transport, store and install according to the construction schedule.
• Can be manufactured according to the dimensions and technical requirements of each project.

Effective Selection and Use

When selecting precast reinforced concrete lintels, it is necessary to determine the dimensions of the opening, wall thickness, load above the opening and requirements specified in the structural design.

The lintel length must be suitable for the width of the opening and provide adequate bearing length at both ends in accordance with the project’s technical requirements.

Before installation, inspect the product’s appearance, dimensions, installation location and bearing surfaces. Products showing cracks, breakage or other damage that may affect their load-bearing capacity should not be used.

Do not cut, drill or damage the internal steel reinforcement without approval from the responsible technical personnel.

Transportation and Storage

Transportation

• Do not drag, throw or subject the product to strong impacts.
• Use a vehicle with a flat loading surface and securely fasten the product.
• Support the product at appropriate positions to prevent concentrated loads.
• Do not place heavy materials directly on top of the lintels.
• Inspect the condition of the product after delivery to the construction site.

Storage

• Place the products on a flat, stable surface with suitable supports.
• Do not place the products directly on soil, mud or waterlogged areas.
• Sort the products by size and specification for convenient use.
• Do not stack the products excessively high or subject them to uneven loads.
• Store the products in an area that does not obstruct walkways or construction activities.

Quality Standards

HAN precast reinforced concrete lintels are manufactured under a quality management process that controls material properties, dimensions, concrete grade and load-bearing capacity.

Product selection and use must comply with the structural design, the project’s technical requirements and the applicable provisions of TCVN 5574:2018, TCXDVN 356:2005 and other current construction standards.
