High-Capacity 170mm PVC Guttering for Commercial, Industrial & Large Roof Areas

Kayflow SuperDeep 170 is a high-capacity commercial guttering system designed to manage substantial volumes of rainwater from larger roof areas. With its 170mm wide, 108mm deep profile, SuperDeep provides an effective rainwater drainage solution for warehouses, industrial units, agricultural buildings, commercial premises and suitable larger domestic properties.

Unlike standard domestic guttering, Kayflow SuperDeep has been developed for installations where increased rainwater capacity is essential. Its deep, semi-elliptical profile combines a generous gutter capacity with a practical design that can be incorporated into a wide range of roofline applications.

Manufactured from durable PVC-U, the system provides a lightweight, corrosion-resistant alternative to traditional metal guttering, supported by compatible commercial rainwater fittings.

In this guide, we explain the benefits of Kayflow SuperDeep 170, its dimensions and flow performance, suitable applications, downpipe options and the components required for a complete installation.

What Is Kayflow SuperDeep 170 Guttering?

Kayflow SuperDeep 170 is a commercial and industrial rainwater guttering system designed for larger roof areas and demanding drainage requirements.

The system features a 170mm wide gutter profile with a depth of 108mm, providing significantly greater water-carrying capacity than smaller domestic guttering systems.

Its deep, semi-elliptical shape is designed to efficiently collect and transport rainwater towards compatible outlets and downpipes.

SuperDeep 170 is particularly suitable for buildings where a standard Half Round, Deepflow or Ogee guttering system may not provide sufficient drainage capacity.

The correct guttering system should always be selected using the effective roof area, rainfall design requirements and manufacturer's performance data.

Key Features & Benefits of Kayflow SuperDeep 170

Why Choose Kayflow SuperDeep Commercial Guttering?

1. High Rainwater Flow Capacity

One of the main advantages of Kayflow SuperDeep 170 is its ability to manage large volumes of rainwater.

The system's wide, deep profile provides increased water-carrying capacity compared with smaller domestic guttering systems.

Kayflow's published performance data gives a flow rate of 4.3 litres per second when the gutter is laid level and fitted with an end outlet.

Under these conditions, the manufacturer states that the system can drain an effective roof area of up to 205m².

Actual capacity will depend on the gutter fall, outlet location, downpipe arrangement, roof area and design rainfall intensity.

For commercial projects, these factors should be checked during the drainage design process rather than relying on the gutter dimensions alone.

2. Designed for Large Roof Areas

Commercial and industrial roofs can collect substantial amounts of rainwater during heavy rainfall.

Kayflow SuperDeep 170 is designed to accommodate higher drainage demands, making it a practical option for suitable warehouses, industrial buildings, agricultural premises and large roof structures.

Its increased capacity may help reduce the number of gutter outlets required in some correctly designed installations, although this depends on the roof layout and hydraulic calculations.

3. Deep, Semi-Elliptical Gutter Profile

SuperDeep features a distinctive semi-elliptical profile rather than a conventional Half Round shape.

Measuring 170mm wide and 108mm deep, the gutter provides a generous channel for collecting and transporting rainwater.

The profile is designed to offer high-capacity drainage while maintaining a relatively neat appearance along commercial and industrial rooflines.

4. Lightweight & Corrosion-Resistant PVC-U

Kayflow SuperDeep is manufactured from PVC-U, making it lighter than many traditional metal guttering systems.

PVC-U does not rust, reducing the need for corrosion-related painting and maintenance.

The system still requires regular inspection, cleaning and appropriate fixing arrangements to maintain reliable performance.

5. Compatible Commercial Rainwater Fittings

The SuperDeep 170 range includes purpose-designed components that allow complete rainwater systems to be assembled.

Compatible fittings include gutter unions, fascia brackets, running outlets, angles and stop ends.

The system can be connected to suitable large-diameter rainwater pipework using the correct manufacturer-approved outlets and connections.

Where Can Kayflow SuperDeep 170 Guttering Be Used?

Warehouses & Distribution Centres

Large warehouse roofs can produce substantial rainwater runoff during heavy rainfall.

Kayflow SuperDeep provides a high-capacity guttering option for suitable warehouse and distribution centre roof drainage designs.

Industrial Buildings & Factories

Industrial premises often have extensive roof areas requiring effective rainwater management.

SuperDeep 170 can be incorporated into appropriately designed rainwater systems where higher gutter capacity is required.

Agricultural Buildings & Barns

Agricultural buildings, barns and storage sheds may have large roof surfaces that generate significant runoff.

The lightweight PVC-U construction and high-capacity profile make SuperDeep a practical option for suitable agricultural applications.

Commercial Units & Workshops

Commercial workshops, business units and trade premises can benefit from a guttering system designed for larger roof areas.

SuperDeep provides an alternative to standard domestic guttering where the calculated drainage requirements justify a higher-capacity system.

Larger Domestic Properties

Although primarily designed for commercial applications, SuperDeep 170 may also be suitable for larger domestic buildings with extensive roof areas.

The correct system should always be determined by the roof drainage requirements rather than property type alone.

Kayflow SuperDeep 170 Guttering Dimensions

Kayflow SuperDeep 170 is designed around a large-capacity gutter profile.

Gutter Width: 170mm

Gutter Depth: 108mm

Material: PVC-U

Common Gutter Length: 4 metres, with other lengths subject to product availability.

Downpipe Connections: Suitable 100mm or 110mm arrangements using compatible outlets and fittings.

Maximum Bracket Spacing: 600mm, subject to the latest manufacturer's fixing guidance and installation conditions.

These dimensions make SuperDeep considerably larger than conventional domestic guttering systems.

How Much Rainwater Can SuperDeep 170 Handle?

Kayflow publishes independently tested performance data for its rainwater systems.

For SuperDeep 170, the published figures include:

Flow Rate: 4.3 litres per second with a level gutter and end outlet.

Effective Roof Area: Up to 205m² under the manufacturer's specified test conditions.

The system may achieve higher flow rates with a suitable fall and outlet arrangement, but the correct design figures should be taken from Kayflow's latest technical documentation.

A central outlet can alter the effective drainage capacity because rainwater can flow towards the outlet from both directions.

However, the actual capacity of a complete installation depends on the entire rainwater drainage system, including downpipe sizing and outlet configuration.

For larger commercial roofs, drainage calculations should be completed in accordance with applicable standards and project requirements.

SuperDeep vs Standard Commercial Guttering

Traditional commercial PVC guttering systems often use larger Half Round profiles.

Kayflow SuperDeep differs by combining a 170mm width with a deeper semi-elliptical shape.

The additional depth provides a larger channel for collecting rainwater, while the profile is designed to deliver increased drainage capacity.

Compared with smaller domestic systems such as Half Round and Deepflow, SuperDeep is intended for substantially larger roof drainage demands.

However, not every commercial building requires a 170mm gutter. Smaller systems may be sufficient where the calculated roof area and rainfall conditions allow.

The best guttering system is the one that provides the required drainage performance without unnecessary oversizing.

What Colours Are Available in Kayflow SuperDeep Guttering?

Black SuperDeep 170 Guttering

Black is a popular choice for industrial buildings, warehouses and commercial properties.

It provides a traditional, understated finish that coordinates with many roofing and cladding materials.

Grey SuperDeep 170 Guttering

Grey is a practical option for commercial and industrial installations, particularly where the guttering needs to complement grey roof sheets, metal cladding or other external finishes.

Brissco supplies Kayflow SuperDeep 170 guttering in Black and Grey, together with selected compatible fittings.

What Fittings Do You Need for SuperDeep 170 Guttering?

A complete Kayflow SuperDeep installation requires compatible components designed specifically for the 170mm gutter profile.

SuperDeep Gutter Lengths

The 170mm gutter lengths collect rainwater from the roof and direct it towards the outlets.

Fascia Brackets

Purpose-designed SuperDeep fascia brackets support the guttering and maintain the correct alignment.

Kayflow specifies a maximum bracket spacing of 600mm for SuperDeep 170, with fixing requirements dependent on the supporting structure and installation conditions.

Gutter Union Brackets

Union brackets connect adjacent gutter lengths using the system's designed jointing and sealing arrangement.

Running Outlets

Running outlets provide the connection between the guttering and compatible rainwater downpipes.

The correct outlet must be selected for the required pipework arrangement.

Gutter Angles & Stop Ends

Compatible angles allow the guttering to follow changes in the roofline, while stop ends close the ends of gutter runs.

Commercial Downpipes & Connections

Suitable large-diameter rainwater pipework carries water from the gutter outlets to the drainage system.

The pipe diameter and connection arrangement should be selected according to the manufacturer's guidance and the drainage design.

How to Install Kayflow SuperDeep 170 Guttering

Installing commercial guttering requires careful planning, suitable structural support and compliance with the manufacturer's fixing instructions.

Step 1: Calculate the Effective Roof Area

Determine the effective roof area contributing rainwater to each gutter run.

Use the appropriate rainfall design criteria and Kayflow's published capacity data to confirm that SuperDeep 170 is suitable.

Step 2: Plan the Outlet Positions

Identify suitable outlet and downpipe locations.

Consider the gutter run length, roof geometry, available drainage connections and the expected volume of rainwater.

Step 3: Check the Supporting Structure

Ensure the fascia or supporting structure can accommodate the guttering, fixings and expected water and environmental loads.

Commercial installations may require additional structural consideration.

Step 4: Install the Fascia Brackets

Fit compatible SuperDeep fascia brackets at the manufacturer's recommended maximum spacing of 600mm.

Follow the specified fixing requirements and establish the correct gutter alignment and fall.

Step 5: Fit the Gutter Lengths

Cut gutter lengths accurately, remove burrs and position the guttering securely into the brackets.

Step 6: Install Unions, Outlets & Angles

Connect the gutter lengths using compatible Kayflow SuperDeep fittings.

Ensure all seals and retaining components are correctly fitted, and follow the manufacturer's guidance for thermal expansion.

Step 7: Connect the Downpipes

Fit suitable downpipe connections and pipework, ensuring the arrangement provides adequate capacity and securely supported drainage.

Step 8: Inspect & Test the Installation

Check all brackets, unions, outlets and downpipe connections.

Where practical and safe, test the system to confirm correct water flow and identify any leaks or drainage restrictions.

Commercial roof work should be carried out by competent installers using appropriate working-at-height precautions.

How to Maintain Commercial SuperDeep Guttering

Although PVC-U commercial guttering is corrosion-resistant, regular maintenance is essential.

Inspect gutter runs for leaves, moss, roof debris and other obstructions.

Check outlets and downpipes for blockages that could restrict rainwater flow.

Examine union seals, brackets and fixings for damage or movement.

Ensure that gutter lengths remain correctly supported and aligned.

For warehouses and industrial buildings, inspections may need to be more frequent where roofing debris, nearby trees or other environmental conditions increase the risk of blockages.
