INVERTED BOX RIB (IBR)
Industrial Box Rib Roofing Solution for Strength and Reliability.
IBR Roofing Sheets (Industrial Box Rib) are widely used roofing and cladding materials known for their high strength, excellent load-bearing capacity, and cost-effective performance. The distinctive box-rib profile provides enhanced structural rigidity, making IBR sheets a preferred roofing solution for residential, commercial, industrial, and institutional buildings.
IBR roofing sheets are engineered to perform reliably under varying weather conditions, offering long-term protection while maintaining a clean and professional appearance.
Available Thickness Options.
IBR Roofing Sheets are available in multiple thicknesses to meet structural and budget requirements:
0.40 mm – Suitable for residential roofing and light-duty structures
0.45 mm – Balanced option for mixed residential and commercial use
0.50 mm – Ideal for industrial buildings, warehouses, and long-span roofing
Increased thickness improves structural strength, wind resistance, and longevity.
Why IBR Roofing Sheet Is Important.
1. High Structural Strength
The box-rib design increases rigidity, allowing the sheets to span longer distances with minimal deflection, reducing the need for closely spaced supports.
2. Excellent Corrosion Resistance
The aluminium–zinc alloy coating provides superior protection compared to traditional galvanized sheets, ensuring longer service life with minimal maintenance.
3. Cost-Effective Roofing Solution
IBR roofing offers an excellent balance between performance, durability, and affordability, making it a popular choice across all market segments.
4. Efficient Water Drainage
The deep rib profile promotes fast water runoff, reducing the risk of water pooling and leakage during heavy rainfall.
5. Thermal Performance
High aluminium content reflects solar radiation, contributing to lower indoor temperatures and improved comfort in warm climates.
6. Wide Market Applicability
IBR roofing sheets are suitable for:
Residential buildings
Commercial complexes
Industrial warehouses and factories
Schools, hospitals, and agricultural structures.
Material Composition (Industry-Standard AZ150).
IBR Roofing Sheets are manufactured using industry-standard aluminium–zinc alloy (Al-Zn) coated metal, designed to deliver superior corrosion resistance and extended service life.
Typical aluminium–zinc alloy composition includes:
Aluminium – 55%
Provides a protective barrier against corrosion and reflects heat, helping to reduce thermal gain within buildings.Zinc – 43.4%
Offers sacrificial protection, especially at cut edges and fastener points, preventing rust formation over time.Silicon – 1.6%
Improves adhesion between the aluminium–zinc coating and the metal substrate, enhancing coating durability and consistency.
This composition, when applied with standard coating weights such as AZ150, ensures dependable performance in humid, coastal, and high-rainfall environments.
