Box Gutter 200 X 200 X 200 – Zincalume®

Order Online: Box Gutter ZINCALUME® measures: 200mm x 200mm x 200mm.

A box gutter is given its name as it is usually “boxed” into the middle or edge of the roof.  The gutter collects the water and disposes of it through the drainpipe.  Box guttering is generally concealed as they are hidden by outside walls that are higher than the edge of the roof tiles or sheeting – that is, you can’t see them when you look at the home, so they are great if you don’t like the look of gutters for whatever reason.

How much fall should a box gutter have?

Frequently Asked Questions (FAQs)

1. What is a box gutter and how does it work?

A box gutter is a type of roof drainage system that’s built inside the roof structure rather than hanging off the edge. It gets its name from its square “box” shape. Rainwater flows from the roof into the gutter, then travels down a connected drainpipe to the ground. Because box gutters are hidden behind outer walls or parapets, you can’t see them from the street — making them a great choice for homeowners in Victoria who want a cleaner, more modern look for their home.

2. Why is Zincalume steel a good choice for box gutters in Victoria?

Zincalume steel is coated with an aluminium-zinc alloy, which gives it excellent protection against rust and corrosion. This makes it especially well-suited to Victoria’s climate — from Melbourne’s wet winters to coastal humidity near the bay. Compared to plain galvanised steel, Zincalume lasts longer and requires less maintenance. Singh Roofing Supplies uses BlueScope Zincalume — Australia’s most trusted steel brand — so you know you’re getting a quality product built to last.

3. What size box gutter do I need for my roof?

The right box gutter size depends on your roof area, the amount of rainfall your area receives, and your drainage setup. The 200mm x 200mm x 200mm box gutter is a popular standard size for residential and light commercial builds across Victoria. If your roof has a large catchment area or experiences heavy rainfall, you might need a wider profile.

Yes! Singh Roofing Supplies offers custom-cut and custom-folded box gutters to suit your exact specifications. Whether you need a different length, fold angle, or profile, the team can manufacture it for you. Custom orders are available in both Zincalume® and Colorbond® steel. Just contact the sales team at orders@singhroofingsupplies.com.au with your measurements and project details, and they’ll take care of the rest — with fast turnaround and delivery within 48 hours across Victoria.

5. What’s the difference between a Zincalume box gutter and a Colorbond box gutter?

Both are made from high-quality BlueScope steel and offer excellent durability, but there’s one key difference: colour. Zincalume box gutters have a natural silver-grey metallic finish and are unpainted — ideal when the gutter is fully concealed and colour doesn’t matter. Colorbond box gutters are pre-painted in a wide range of colours from the full Colorbond® range, which can be useful if part of the gutter is visible or if you want it to match your roof or walls.
