Industrial Downpipes – Safe & Efficient Rainwater Disposal for Industrial Buildings
Industrial roofs handle large volumes of rainwater, especially during heavy monsoons. Without proper drainage, water overflow can damage walls, foundations, and roofing systems. Industrial downpipes play a critical role in safely carrying rainwater from gutters to ground-level drainage systems.
At Buildtech Roofing Solutions, we manufacture and install heavy-duty industrial downpipes designed for high flow capacity, corrosion resistance, and long-term reliability.
What Are Industrial Downpipes?
Industrial downpipes are vertical drainage pipes connected to roof gutters. Their function is to transport rainwater safely from the roof to stormwater drains or collection pits, preventing overflow and structural damage.
How Industrial Downpipes Work
- Rainwater is collected by roof gutters
- Water flows into the downpipe inlets
- Downpipes carry water vertically downward
- Water is discharged into drainage systems
- Roof edges and walls remain protected
Because of this controlled flow, buildings remain safe during heavy rainfall.
Types of Industrial Downpipes
1. Rectangular Downpipes
- High discharge capacity
- Ideal for box gutter systems
- Common in large industrial sheds
2. Round Downpipes
- Smooth water flow
- Easy installation and maintenance
- Suitable for commercial and light industrial buildings
3. Custom-Fabricated Downpipes
- Designed as per site layout
- Compatible with unique gutter profiles
- Preferred for complex industrial roofs
Materials Used
Buildtech industrial downpipes are manufactured using:
- GI (Galvanized Iron)
- PPGI (Colour-Coated Steel)
- PPGL (Galvalume Steel)
- Aluminium (on request)
These materials ensure durability, corrosion resistance, and long service life.
