ALTERNATIVE STEEL STRUCTURES AND ROOFING SOLUTIONS

1. Pre-Engineered Buildings (PEB)

   • Cost-effective and fast to erect.

   • Modular design, suitable for warehouses, factories, and showrooms.

   • Uses high-tensile steel with bolted connections.

2. Light Gauge Steel Structures (LGSS)

   • Cold-formed steel sections, lighter than conventional steel.

   • Suitable for housing, offices, and modular buildings.

   • Fire- and termite-resistant, more sustainable than wood.

3. Structural Insulated Panels (SIPs) with Steel Frames

   • Sandwich panels with steel facings and insulated cores.

   • Great for thermal efficiency and quick installation.

4. Hybrid Systems (Steel + Concrete/Timber)

   • Combines steel frames with concrete slabs or timber elements.

   • Reduces material cost while keeping structural strength.

5. Space Frame Structures

   • 3D truss-like systems with tubular steel members.

   • Ideal for large-span roofs (stadiums, airports, auditoriums).

1. Standing Seam Metal Roofing

   • Durable, leak-resistant, and allows solar panel integration.

   • Made of steel, aluminium, or zinc-coated sheets.

2. Sandwich Panel Roofing

   • Steel sheets with PU, PIR, or rockwool insulation cores.

   • Provides insulation, soundproofing, and fire resistance.

3. Colorbond / Coated Steel Sheets

   • Lightweight, corrosion-resistant steel sheets with multiple color options.

   • Popular for residential and commercial roofing.

4. Tensile Membrane Roofing (Steel + Fabric)

   • Lightweight fabric structures supported by steel cables and frames.

   • Aesthetic, UV-resistant, and suitable for malls, stadiums, canopies.

5. Green Roofing with Steel Decking

   • Steel deck base with waterproofing and vegetation on top.

   • Sustainable and energy-efficient solution for urban spaces.

6. Solar-Integrated Steel Roofing

   • Standing seam or trapezoidal steel panels embedded with thin-film PV.

   • Reduces need for separate solar panel installations.

✅ Key Advantages of Steel-based Alternatives

• Faster construction vs traditional brick/concrete.

• High durability and resistance to pests, fire, and extreme weather.

• Compatible with modern modular and green building trends.
