The Zincalume box gutter is a 200 x 400 x 200mm internal gutter with the largest base in the range, boxed into the roof to collect water from a big roof area or a wide valley.

Installation

Fix the box gutter into the roof structure with box gutter brackets, setting the fall at a minimum of 1:200 so water drains to the outlet. The 400mm base carries a high volume of water, so it suits a large roof or a wide valley. Connect the gutter to the downpipe at the outlet and fit an expansion joint on a long run.

Applications

• Concealed internal gutters on large roofs
• Wide valley and parapet gutter runs
• Zincalume roofs and coastal areas
• High-capacity internal drainage

Frequently Asked Questions

When do I need a 400mm base box gutter?

Use it where a large roof area or a wide valley feeds a lot of water into the gutter. The 400mm base carries a high volume and keeps the fall manageable.

Why use the Zincalume finish?

Zincalume resists corrosion without painting, and because a box gutter is concealed the finish does not affect the look of the roof. It suits Zincalume roofs and coastal areas.

What fall does it need?

A minimum fall of 1:200 is required so water drains to the outlet. Set the fall with the brackets before fixing the gutter.

How is it priced?

It is priced per lineal metre including GST and cut to your required length with a tolerance of +200mm / -0mm.
