Introduction
Correct choice of mild steel sheets for roofing and cladding can have a significant positive impact on the sustainability, economics, and functional aspects of a building in the long run. Considering the varying climate conditions in India, which are characterized by high temperatures, a substantial amount of rainfall, and humidity at most times of the year, the appropriate selection of MS sheets becomes even more important.
Mild steel sheets are one of the most commonly used construction materials for both residential, commercial, and industrial structures due to their strength, malleability, and relatively lower prices. All MS sheets are however, not similar in all respects. Appropriate choice can be decided based upon factors such as the thickness, coating, and the finish of the sheet, and importantly, the intended use of the sheets.
This information will serve to be of great utility to builders, contractors, and owners based in Ahmedabad, Gujarat, or India, and looking to select appropriate mild steel sheets for roofing and cladding purposes.
What Are Mild Steel Sheets?
Mild steel sheet is a flat product formed from low carbon steel. Due to its low carbon content, mild steel is extremely workable, easily weldable, and well-suited for almost any fabricating procedure.
The most common types of mild steel sheet that you would find are:
- Hot Rolled Steel Sheets
- Cold Rolled Steel Sheets
- Galvanised Steel Sheet
Each of the above types is suited for its particular use.
Why Mild Steel Sheets Are Used for Roofing & Cladding
Commonly used as roofing & cladding sheets in India because of the following reasons
- High strength and long life,
- reasonable price,
- easily available in the market,
- easily fabricated to the desired size, shape, and size
- compatible with coating and finish.
Key Factors to Consider When Choosing Mild Steel Sheets
1. Thickness of the Sheet
When choosing MS sheets, thickness plays a crucial role:
• Thin sheets (0.5 mm – 1 mm): appropriate for light cladding
• Medium thickness sheets (1mm – 3mm): ideal for roofing and construction
• Heavy thickness sheets (3 mm +): recommended for construction purposes
The thicker sheets provide enhanced strength, but will lead to greater cost and weight.
2. Type of Sheet (HR, CR, GI)
There is importance in choosing the right one.
- Hot Rolled Sheets (HR) –Used in heavy duty structure application. Slightly rough surface. Low cost. Use for frameworks, base structures.
- Cold Rolled Sheets (CR) –Smooth surface finish, with dimensional accuracy is higher. Used in aesthetic applications.
- Galvanised Sheets (GI) – Coated with zinc. Corrosion resistance is excellent and is ideal for rooftops and outdoors. Highly recommended for Indian conditions.
3. Weather Resistance (Important for India)
The climate in India varies so much.
- Coastal – hot and humid
- North – extremely hot/cold
- West (e.g., Ahmedabad) – extremely hot and dusty
→ Use galvanized/coated sheets for roofing.
→ Use corrosion-resistant sheets for cladding.
4. Coating and Finish
Coatings provide strength and visual benefits:
- Galvanized Coating: Corrosion protection
- Painted Sheet: Attractive finish
- Powder Coating: Tough finish
Use coated sheets outdoors.
5. Load-Bearing Requirement
Coatings provide strength and visual benefits:
- Galvanized Coating: Corrosion protection
- Painted Sheet: Attractive finish
- Powder Coating: Tough finish
Use coated sheets outdoors.
6. Size and Dimensions
Sizes available:
- Regular size: 8 x 4 ft
- Other sizes can be made to order
Consider the following when choosing a size:
- Where the boards will be installed
- Structural design
7. Cost and Budget
Mild steel sheet comes under a cheaper category; the rates differ in terms of:
- Thickness
- Type ( HR, CR, GI)
- Steel rates prevailing in the market
- Quantity
