What is Hollow Core Slabs & Why Use It?

Hollow core slabs are precast concrete elements that are prestressed and are manufactured using long-line steel casting pallets. Prestressed hollow core slabs are used for concrete frameworks that support excessive weight loads and in large open spaces. Bot material and labor will be saved when you use hollow core slabs in the process.

Hollow core slabs enable the construction of concrete frameworks that would be impossible to achieve with other systems. Structures with prestressed hollow core slabs are an ideal building solution for industrial constructions, residential buildings, and civil engineering works. To reduce the weight of the concrete framework the prestressed slabs have lengthwise hollow cores in the bottom section which means that they do not require transversal reinforcement. When you use prestressed hollow core slabs and beams you are guaranteed to save money, as well as beams, columns, material, and, most importantly, labour costs.

Below are the advantages associated with hollow-core slabs

1. Speed of Erection

Hollow core slabs can be installed within no time and safely on-site in variable weather conditions. The number of workers needed on-site are minimum and also provides the immediate working platform. These benefits allow much faster completion of flooring and quicker erection of buildings, increasing profits for the contractor.

2. Lower Material Usage

Hollow core slabs are prestressed elements that allow for shallower elements, thus reducing the amount of steel and concrete used in the construction. Supporting frame elements, columns and beams can also be reduced.

3. Structural Efficiency

Hollow-core offers a versatile solution in steel and in concrete structures. This makes them suitable for a wide range of applications, from housing to commercial and industrial buildings, car parks, and sports stadia.

4. Quality

Prestressed hollow core is manufactured using high-quality raw materials, such as high strength concrete, and low relaxation steel wire/strand under strict quality assurance procedures and controls that meet the required national and international standards. Thus the quality of the slabs is maintained.

5. Sound Insulation

Prestressed hollow core provides superior sound insulation, an important consideration when used in residential buildings.

6. Thermal Efficiency

7. Sustainable

Hollow core slabs are extremely durable construction products that offer an exceptional lifespan through resistance to corrosion and cracking. As it is produced in a controlled factory environment, it also enables the reduction of waste, noise, and emissions during the entire construction process.

Why choose Precast Sandwich Wall Panels for buildings?

Sandwich wall panels are called so because of the configuration of the panels. The panels are constructed using 3 basic components. Two similar looking outward facing layers and a thick core. The name is derived as sandwich because these two panels act as a bread of the sandwich and the core is the meat. These 2 outward facing layers helps to increase the overall durability of the panel.

The thick middle core is of low strength and made out of mineral wool. The two outer plates are made up of steel, which provides the best protection to the panel. The two outer plates are made up of steel which provides the best protection against any damage if happens in future. And all these 3 layers are clubbed together to form a sandwich and connected to each other through specialized adhesives.

These sandwich panels are being used in the construction industry from roof panels to th3 floor panels. Lets look into the exact benefits of a sandwich wall system on a structure

1. Widely applicable

These sandwich panels are widely applicable in almost all sectors. They can be used in the industries like oil and as industry, wind energy industry and in the infrastructure industry. These panels are mainly used for internal and external wall coverings and also for partition walls.

2. Fast installation

These blocks can be added effectively and efficiently without the use of any big instruments to lift. Consequently, it saves you a lot of time and labour costs.

3. Good thermal insulation

As discussed earlier the middle part of the sandwich wall panel is made of mineral wool which provides a good thermal protection. Thermal protection is very much essential because it allows for temperature regulations inside the compartments. In order to provide pleasant working environment temperature is kept at a comfortable level.

4. Excellent non-combustible

To ensure fire safety the insulation has to be non-combustible, And these panels are designed in such a way that they act as a non-combustible components.

5. Mass Production with Customization

The biggest benefit associated with these sandwich panel system is, they provide you cost-savings on mass production which is highly flexible. We can use the same panel system each time, This panel system can be configured in whichever layout the end customer needs. Afterwards, the custom panel still fits perfectly into our standard wall panel assembly, minimizing any additional work to fabricate or assemble.
