HORNVAL drainage: 150 mm steel gutter — industrial system

A gutter must collect water from a large roof area and guide it in a controlled way. Metal drainage systems combine this task with steel’s strength and an existing protective finish. They suit homes, workshops and larger buildings where stable geometry and compatible parts matter. The benefit extends beyond the gutter itself to reducing uncontrolled runoff around façades, ground-level areas and entrances.

Steel provides rigidity even with a relatively thin wall. Shaped edges and a suitable cross-section help retain the gutter profile and an orderly water route. Steel changes length less with temperature than PVC, which can benefit long eaves runs; thermal movement must still be accommodated. On larger commercial buildings, rigidity helps maintain a straight drainage line, while on houses it supports a neat visible detail. The metal finish also coordinates with coated flashings around the eaves.

Water reaches both the inside and outside of a gutter. In systems made from double-sided coated steel, protection covers both surfaces. The coating supports corrosion resistance and provides a colour coordinated with flashings and the façade. It also protects the inside, where water passes most frequently and inspection is less convenient. A smooth surface assists flow and cleaning. Protection and appearance are therefore part of the base material rather than separate treatments for every visible component.

Angles, outlets, unions, bends and downpipes create a planned water route around the building. Compatible components reduce improvised transitions and alterations. The system can match the roof area and rainwater arrangements, including a planned storage tank. Fittings guide water around corners and façade projections towards the outlet, keeping it away from entrances, terraces and circulation routes. Suitable capacity and regular clearing allow the steel system to perform its role in a home or outbuilding.

SteelProfil offers metal gutter systems and a wider range of first- and second-grade materials, including selected stock items. Competitive prices and promotions help assemble the drainage package. We match gutters with suitable downpipes, unions and the details required for the particular building.
