Constructing with Proper Strong Metals According to the Size of the House

When building a house, one of the most critical decisions is choosing the right construction materials, especially metals. Using strong and appropriately sized metals ensures the structural integrity, durability, and safety of your home. At National Cement Co. Ltd., we understand the importance of quality materials in construction. In this blog, we’ll guide you on how to select the right metals based on the size of your house.

Why Using the Right Metals Matters

The strength and longevity of a building depend heavily on the metals used in its framework, roofing, and reinforcements. Weak or undersized metals can lead to:

• Structural failures (cracks, bending, or collapse)
• Poor load-bearing capacity
• Increased maintenance costs
• Safety hazards during extreme weather

Choosing the correct metal type and size ensures:
✔ Enhanced durability
✔ Better resistance to weather and corrosion
✔ Optimal load distribution
✔ Long-term cost savings

Key Metals Used in Construction

1. Reinforcement Steel (Rebar)

Used in concrete structures (foundations, beams, columns), reinforcement steel must be strong enough to withstand tension and compression.

Recommended Sizes Based on House Size:

• Small Houses (1-2 floors): 10mm – 12mm diameter rebars
• Medium Houses (3-4 floors): 12mm – 16mm diameter rebars
• Large Houses & Multi-story Buildings (5+ floors): 16mm – 20mm+ diameter rebars

2. Structural Steel (Beams & Columns)

For framing and support, structural steel (I-beams, H-beams) must be chosen based on load requirements.

Recommended Sizes:

• Single-story homes: Lightweight beams (150mm – 200mm depth)
• Multi-story homes: Heavy-duty beams (200mm – 400mm depth)

3. Roofing Sheets (Galvanized Steel & Aluminum)

The roof must resist wind, rain, and heat.

Recommended Thickness:

• Small roofs: 0.4mm – 0.5mm
• Large roofs (high wind areas): 0.6mm – 0.7mm

4. Nails, Screws, and Fasteners

Using the right fasteners prevents loosening and corrosion.

• For wood framing: Galvanized or stainless steel nails
• For metal roofing: Self-drilling screws with rubber washers

Factors to Consider When Choosing Metals

1. House Size & Load Requirements – Larger homes need thicker, stronger metals.
2. Climate Conditions – Coastal areas require corrosion-resistant metals (stainless steel, galvanized steel).
3. Budget vs. Longevity – Investing in high-quality metals reduces future repair costs.
4. Local Building Codes – Ensure compliance with Kenyan construction standards.
