Product Information

Full details

The FloPlast 16mtr 170mm Industrial Gutter Kit is engineered for contractors and property owners managing large commercial, agricultural, or expansive residential roof areas that require high-capacity water discharge. Featuring a robust 170mm profile and a stopend outlet configuration, this system excels at handling high volumes of rainfall; however, the large dimensions and 110mm downpipe requirements necessitate a more substantial mounting structure compared to standard domestic systems.

FAQs

Can I use this for a domestic shed?

While technically possible, the 170mm profile is much larger than standard shed guttering. It is better suited for larger commercial or agricultural buildings.

Does this kit include the 110mm downpipe?

No, this kit includes the guttering components and fittings. You will need to purchase the 110mm downpipes separately.

What is the weight capacity of this guttering?

The system is designed to handle high volumes of water, but its structural limit depends on the integrity of your fascia boards. Ensure they are in good condition before mounting.

Do I need to glue the joints?

No, the joints use rubber seals. Do not use solvent glue, as the system is designed to expand and contract with temperature changes.

Is the black colour permanent?

The material is UV-stabilised to retain its colour, but like all PVC products, it may show minor weathering over many years.

Can I cut the 4m lengths?

Yes, you can cut the gutter lengths to size using a fine-toothed hacksaw. Always file the cut edges smooth after sawing.

Troubleshooting

Water leaking at the joints

Check that the rubber seals are properly seated and that the gutter lengths are fully pushed into the union joints.

Guttering sagging in the middle

Ensure fascia brackets are installed at no more than 600mm intervals and that they are securely fastened to the fascia board.

Water pooling rather than draining

Verify the slope of the gutter run; you may need to adjust the height of the brackets to create a consistent downward gradient toward the outlet.

Pros and Cons

Pros

  • Superior water discharge performance for large roofs
  • UV-stabilised material ensures long-lasting black finish
  • Easy-to-install rubber seal joint system
  • Everything included for a 16-meter run
  • Compatible with standard 110mm round downpipe systems

Cons

  • Not suitable for small residential structures
  • Requires substantial fascia support due to increased weight/size
  • Larger profile is more visible than standard slimline gutters

Setup, Compatibility & Care

Installation requires standard site tools such as a hacksaw, file, and drill. Begin by marking the fall (slope) along the fascia board to ensure water moves toward the outlet; a gradient of 1:350 is recommended. Install fascia brackets every 600mm to ensure proper support.

Compatibility: This kit is specifically designed for 110mm round downpipes. Ensure your downpipe connectors match this diameter for a secure fit.

Care: To maintain the system, periodically clear debris like leaves or moss from the gutter channels to prevent blockages. Clean the exterior surfaces with a soft cloth and mild soapy water if dust accumulates; avoid harsh abrasive cleaners or solvent-based chemicals that could damage the UV-protective layer.
