Galvanized Drainage Grates vs Plastic

The right drainage grates are crucial for ensuring proper safety and water drainage near your home, public walkways, or work site. That being said, how do you choose between plastic drainage grates and galvanized drainage grates? And what’s the difference?

In this article, we’ll discuss the key distinctions between these two types of grates so that you can decide which one may be best for you.

The Differences: Galvanized Grate vs Plastic Grate

Plastic Drainage Grates

Plastic drainage grates are created from a type of thermoplastic and then molded. This makes them suitable for areas where significant temperature changes are not expected. However, exposure to extremely hot liquids may warp the drainage grating.

Regarding load restrictions, plastic grating should only be used for load classes starting with "A" because of its lower strength, making it unsuitable for heavy weights.

Advantages of Plastic Grates

• Options – Plastic drain grates can come in several sizes and shapes due to the custom molding process.
• Lightweight – Installation is easy since the transportation and manipulation of plastic grates require minimal heavy lifting.
• Cost – Plastic trench grates are generally cheaper compared to other, more durable materials.

Disadvantages of Plastic Drainage Grates

• Weakness – Plastic drains do not have the strength to withstand heavy vehicle or foot traffic, nor extreme temperatures, which can warp the material.
• Longevity – Plastic lacks long-term durability. Despite lower initial costs, it may result in higher maintenance expenses over time.

Galvanized Drain Grates

Galvanized steel grates are crafted from galvanized metal or steel and are used in diverse settings such as commercial job sites, restaurants, breweries, and parks. These grates are often employed near homes where strength, durability, and reliability are crucial for efficient water drainage, commonly seen in trench grates.

Additionally, galvanized drainage grates exhibit resistance to bacteria and rust, ensuring longer durability.

Advantages of Galvanized Drainage Grates

• Cleaning – Galvanized grates are highly hygienic, as metal naturally prevents bacteria and debris from adhering to the surface, simplifying the cleaning process.
• Aesthetics – The clean metal appearance of galvanized grates is visually appealing, providing a more sophisticated look than plastic, which can appear cheap.
• Safety – Galvanized grates reduce hazards such as heels getting stuck or wheels and walking aids experiencing difficulty. They also support greater weights.
• Long-term durability – Their longevity means you won't have to worry about frequent replacements, saving you money in the long run.

Disadvantages of Galvanized Grating

• Heat absorption – Due to its metallic nature, galvanized material can absorb heat quickly, potentially increasing the surrounding temperature and causing discomfort.
• Potential for theft – High demand for galvanized drainage covers makes them targets for theft, although this is not very common.

The Final Word

Having the proper drain covers is essential for ensuring safety and proper water flow, protecting your belongings, loved ones, and enhancing comfort for everyone in the area.

The differences between galvanized and plastic grates boil down to individual preferences and requirements for your water drainage system. Consult your local grating system experts to determine the best material for your needs.
