Drainage gutters for corrugated iron roof: Classification and Quotation

The roof is the part of a building most directly exposed to rain. Installing drainage gutters is an effective solution to collect and drain rainwater, preventing stagnation and keeping the roof surface dry. Therefore, it will protect the walls and interior structures of the house by preventing the penetration of rainwater. What is the structure of a drainage gutter, and how much does it cost? Let’s explore further with Butraco in the article below!

1. Introduction to drainage gutters of corrugated iron roof 

The drainage gutter (also known as tile roof drains or gutters) is a part of the drainage system on the corrugated iron roof. This type of gutter is installed at the edge of the roof, helping to drain water, directing rainwater away from the roof, avoiding the stagnation situation. Gutters can protect the roof from moisture, rot, and water corrosion, keeping a dry and clean condition for the house.

The drainage gutter is designed to slope down to increase the drainage efficiency of the construction project. The structure of a gutter is as follows:

• Trough: A part that directly collects rainwater pouring down from the roof, the usual depth is from 200mm.
• Supports (gutter bracket, sleeves): One end is attached to the purlin, the other end is bent according to the shape of the gutter to support and reinforce the gutter firmly.
• Gutter drain pipe: The size is suitable for the gutter, receiving the rainwater flowing from the roof and then discharging into the environment.
• Water collection funnel (gutter funnel): Connect the gutter and drain pipes, discharging water to the drain pipe, avoiding the situation of overflow causing water penetration.
• Trash rack: This trash rack is used to prevent blockage and stagnation of the drain pipe.

2. What materials are used to make a gutter for corrugated iron roof?

In the process of designing and planning the installation of gutters for corrugated iron roof, it is essential to understand the suitability of each type of material of each project. Currently, there are 2 popular types of materials used to make drainage gutters including corrugated iron and stainless steel.

2.1. Corrugated iron gutters

This type of gutter is made from galvanized iron, gold-plated iron, cold-formed steel, and insulated iron. Due to light weight and low cost, corrugated iron gutters are suitable for factory and warehouse projects, etc. (or large projects that do not require high aesthetics and low budget).

Corrugated iron is an alloy made of iron and carbon, often coated with a protective layer such as galvanized or color-coated to prevent rust. Over time, it is susceptible to oxidation and corrosion if the protective layer is damaged. Projects using corrugated iron gutters need to have a periodic inspection and maintenance plan to ensure the lifespan of the gutter.

2.2. Stainless steel gutters 

As we know, inox or stainless steel is a type of material that can resist to corrosion and has high durability. This type of gutter is often installed for aesthetic projects that require a shiny surface such as villas, hotels, shopping centers and so on.

With the same size, the weight of stainless steel is higher than that of corrugated iron;  therefore it requires to apply reinforcement methods to ensure effective operation and durability of the gutter:

• The thickness of the material used to make supports and columns is thicker than that of the gutter.
• The distance between the welds connecting gutter sections and the distance between the columns and supports is shorter than that of corrugated iron gutters.
• Accessories such as bolts, screws, etc. should be made of sturdy, strong, and corrosion-resistant materials.

3. Quotation for corrugated iron gutters

Each supplier of corrugated iron gutters (excluding the construction and installation stage) may offer a different price, but still based on some basic factors:

• Type of materials: Stainless steel gutters are often more expensive than corrugated iron gutters because of high material prices;
• Dimensions: The length, width, and thickness of the gutter affect the requirements and processing stages. The more difficult the profile of the trough, the higher the weight, processing and installation costs.
• Accompanying reinforcement and installation accessories shall have their quantity and price.
• Order quantity: The higher the number of orders, the lower the cost.
• Transportation costs from the gutter trough supplier to the construction site.
