A Gutter Outlet Lip 100×75 Galvanised is a crucial component in rainwater drainage systems, designed to connect gutters to downpipes efficiently. This fitting ensures smooth water flow from the gutter channel into the downpipe, preventing overflow and water damage to the building’s structure. The 100×75 measurement refers to the outlet’s size, where 100mm is the width (typically matching the gutter) and 75mm is the diameter (suitable for standard downpipes).

Material & Finish

• Galvanised Steel: The outlet lip is made from high-quality steel coated with a layer of zinc (galvanise) to enhance durability and resistance to rust and corrosion.

• Protective Coating: The galvanised finish provides long-term protection against harsh weather conditions, including rain, UV exposure, and temperature fluctuations.

Design Features

1. Precision-Formed Lip: The outlet features a rolled or flanged lip that securely fits into the gutter, ensuring a watertight connection and preventing leaks.

2. 75mm Downpipe Connection: The circular spout is designed to fit standard 75mm round downpipes, allowing for seamless integration into existing drainage systems.

3. Reinforced Structure: The sturdy construction prevents warping or bending under heavy rainfall or debris load.

4. Compatibility: Suitable for use with 100mm-wide gutters, commonly found in residential and commercial buildings.

Installation

• The outlet is typically riveted or screwed onto the gutter channel.

• A sealant or gutter silicone may be applied for additional waterproofing.

• The downpipe is then connected to the outlet spout using appropriate brackets or clips.

Applications

• Residential Roofing: Used in homes to direct rainwater from roofs to drainage systems.

• Commercial Buildings: Ideal for warehouses, sheds, and industrial structures requiring efficient water management.

• Agricultural & Industrial Use: Suitable for farm buildings, workshops, and factories where durable drainage is essential.

Benefits

✔ Corrosion-Resistant: Galvanised coating extends lifespan.
✔ High Durability: Withstands heavy rain, wind, and debris.
✔ Easy Installation: Compatible with standard gutter and downpipe systems.
✔ Cost-Effective: Low maintenance and long-lasting performance.

Maintenance

• Periodically check for blockages (leaves, dirt) to ensure smooth water flow.

• Inspect for rust or damage, especially in coastal areas with salty air.

• Clean with mild detergent and water to maintain appearance.

Standards & Compliance

• Manufactured to meet industry standards for rainwater goods.

• Suitable for use in various climates, including high-rainfall regions.

Conclusion

The Gutter Outlet Lip 100×75 galvanised is an essential fitting for effective rainwater drainage, offering durability, weather resistance, and easy installation. Its galvanised steel construction ensures long-term reliability, making it a practical choice for both residential and commercial gutter systems.

Note: Always ensure correct sizing (100mm gutter width, 75mm downpipe) before installation. For optimal performance, use compatible gutters and downpipes from the same manufacturer.
