Bricks remain one of the most fundamental building materials in construction, used globally for centuries. But while their appearance may seem simple, bricks vary widely in composition, durability, application, and compliance standards.
This comprehensive guide will help you understand what bricks are, their different types, how they are manufactured, where they are used, and most importantly, how to choose the right brick for your project.
What are bricks in construction?
A brick is a rectangular unit made primarily from clay, shale, cement, or other earthen materials. It is hardened through air-drying, kiln-firing, or chemical curing to achieve the necessary strength and shape for building applications. Bricks are known for their compressive strength, fire resistance, thermal insulation, and long-term durability in various weather conditions.
Bricks are often laid in overlapping rows and bonded using mortar, forming walls, partitions, or paving surfaces. In Malaysia, bricks must comply with MS 76 or equivalent international standards to be used in structural applications.
For certified bricks suitable for residential, commercial, and infrastructure use, Unitrade offers durable brick materials backed by strict quality control and nationwide delivery support.
Types of bricks used in Malaysia
There are several categories of bricks used in local construction, each suited for different performance and aesthetic requirements.
Clay bricks
Clay bricks are made from natural clay and fired at high temperatures in a kiln. They are among the most common materials used in load-bearing walls and external facades. Their natural colour, insulation capability, and structural strength make them a popular choice for both traditional and modern architecture.
Clay bricks are typically available in:
- Common red bricks (non-facing, plastered applications)
- Facing bricks (exposed use with colour uniformity)
- Perforated clay bricks (lightweight with better insulation)
Cement bricks
Cement bricks are made using a mixture of sand, cement, and water, moulded and cured without kiln firing. They are widely used in non-load-bearing walls, infill panels, or areas where speed and uniformity are critical. Compared to clay bricks, cement bricks offer smoother finishes and faster production times.
Cement bricks come in both solid and hollow variants. The hollow type reduces weight and material usage without compromising surface coverage.
Facing bricks
These bricks are designed specifically for aesthetic appeal on visible surfaces. Made from either clay or cement with added pigmentation, facing bricks offer consistent colour, weather resistance, and minimal water absorption. They are common in facades, garden walls, and architectural features.
Fire bricks
Also known as refractory bricks, fire bricks are manufactured to withstand high temperatures without losing shape or integrity. These bricks are typically used in kilns, fireplaces, and furnace linings. Their composition includes alumina and silica, which improves their thermal resistance.
Engineering bricks
These dense, strong bricks have low water absorption and are ideal for damp-proof courses, retaining walls, and areas exposed to heavy loads or water ingress. Their strength makes them suitable for civil works and high-rise foundation walls.
Applications of bricks in Malaysian construction
Bricks are used in a wide range of applications, spanning both structural and non-structural contexts:
- External walls: Brick walls provide load-bearing support, thermal comfort, and aesthetic appeal in houses and commercial buildings.
- Partition walls: Bricks are often used to divide internal spaces due to their acoustic insulation and fire resistance.
- Boundary and perimeter walls: Clay and cement bricks are commonly used for fencing, supported by reinforced columns and footings.
- Retaining structures: Engineering bricks help withstand soil pressure in landscape design or slope management.
- Fire-rated enclosures: Fire bricks are mandated in facilities with high heat exposure or fire hazard classifications.
The choice of brick depends on building height, load conditions, local climate, and fire safety regulations.

Brick standards and quality considerations
In Malaysia, bricks used for structural applications should conform to MS 76 (for burnt clay bricks) or equivalent standards. Key parameters that affect performance include:
- Compressive strength: Measured in N/mm², strength requirements vary by application.
- Water absorption: Lower absorption improves durability and resistance to weathering.
- Dimensional accuracy: Uniform size ensures consistent laying and mortar joints.
- Efflorescence: Excess salts can lead to white surface marks; quality bricks are low in efflorescence risk.
Always request test certifications or SIRIM approval when sourcing bricks from suppliers.
If your brick construction includes visible utility terminations, Unitrade’s 304 stainless steel ornamental tubes offer corrosion-resistant finishes for modern detailing.
How bricks are manufactured
The brick manufacturing process varies by type but generally includes:
- Raw material preparation: Clay is mined and mixed with water or additives.
- Moulding: Bricks are shaped using hand moulds or machine presses.
- Drying: Water is evaporated to avoid cracks during firing.
- Firing or curing: Kiln-fired bricks are hardened at 900–1100°C; cement bricks are chemically cured over 7 to 28 days.
- Inspection: Final products are checked for cracks, uniformity, and structural performance.
Some bricks may be wire-cut or extruded for consistent edges, especially for exposed surfaces.
Choosing the right brick for your project
The following factors should guide your decision when selecting bricks:
- Load-bearing needs: For structural walls, use clay or engineering bricks with certified strength.
- Weather conditions: In wet or flood-prone areas, low-absorption bricks are essential.
- Aesthetic preference: Use facing bricks where the brick surface is left exposed.
- Speed of construction: Cement bricks may speed up project timelines due to faster production and curing.
- Budget and availability: Compare long-term performance and sourcing logistics when balancing cost.
By considering these factors, project owners can ensure compliance, structural integrity, and design coherence.
