Industrial Deep Trough (idt)
Heavy-Duty Roofing Solution for Maximum Drainage and Structural Strength.
The Industrial Deep Trough Roofing Sheet is a high-capacity roofing profile specifically engineered for industrial, commercial, and high-rainfall environments. Its deep and wide trough design allows for rapid water discharge, making it ideal for large roof spans, factories, warehouses, workshops, and institutional buildings.
This roofing profile is built for projects where strength, durability, and weather performance are critical requirements.
Available Thickness Options.
Industrial Deep Trough Roofing Sheets are commonly available in:
0.45 mm – Suitable for medium-duty industrial and commercial roofing
0.50 mm – Recommended for heavy-duty industrial applications and long-span roofs
The deeper trough profile combined with thicker gauges delivers exceptional load-bearing capacity and wind resistance.
Why Industrial Deep Trough Roofing Sheets Are Important.
1. Superior Water Drainage Capacity
The deep trough design channels rainwater quickly and efficiently, preventing water accumulation even during intense rainfall.
2. High Structural Strength
The deep profile increases sheet rigidity, allowing for longer spans and reduced support spacing without compromising stability.
3. Enhanced Corrosion Resistance
The aluminium–zinc alloy coating protects against rust and degradation, extending the service life of the roof with minimal maintenance.
4. Ideal for Large-Scale Roofing
Specifically suited for:
Factories and warehouses
Industrial plants
Large commercial complexes
Agricultural and institutional buildings
5. Improved Thermal Performance
The aluminium content reflects solar radiation, helping to reduce internal heat buildup in large enclosed structures.
Material Composition (Industry-Standard AZ150).
Industrial Deep Trough Roofing Sheets are manufactured using aluminium–zinc alloy coated metal, designed to deliver long-term corrosion resistance and structural reliability.
The standard aluminium–zinc alloy composition is:
Aluminium – 55%
Provides superior resistance to atmospheric corrosion and reflects solar heat, reducing thermal load on buildings.Zinc – 43.4%
Offers sacrificial corrosion protection, particularly at cut edges and fastener points, ensuring continued protection over time.Silicon – 1.6%
Enhances bonding between the aluminium–zinc coating and the metal substrate, improving coating durability and consistency.
When applied with industry-standard coating weights such as AZ150, this composition ensures excellent performance in humid, coastal, and heavy-rainfall regions.
