Culverts come in several different shapes and designs, as well as a wide range of sizes. They also vary according to their water flow and load capacities, as well as their installation procedure and lifespan. However, one of the most important characteristics to pay attention to when looking to purchase storm drains for sale is the type of culvert pipes. That’s why you should learn more about the main categories of culverts.

What are the different types of culverts?

There are several factors that affect the type of culvert you can purchase. The most important characteristics are roadway height, upstream elevation, and hydraulic factors. They can be boxy, pear-shaped, flat-bottomed, elliptical, and round. The combination of these characteristics creates the six main types of culverts available:

Pipe culvert

This is the most common type of culvert because it is easy to install cheaper than most of the alternatives. Pipe culverts can have various shapes which depend on the conditions of the site, including elliptical and circular. Some of the biggest advantages of pipe culverts are:

• They can achieve any strength through a combination of thickness, reinforcement, and design
• They are an economical option
• They can withhold various compressive and tensile stresses
• Water crossings are underneath their structure

Pipe-arch culvert

Arch culverts, both single and multiple, are best suited for very large openings for significant hydraulic benefit. What’s more, they have low clearance and look more modern than some of the alternatives. These culverts are also very suitable for sites with limited headroom. Other benefits include:

• Boosted low-flow hydraulic capacity
• Aesthetic appearance and shape
• Lightweight
• Easy installation

Box culvert

Box culverts are made from regular and reinforced concrete. They can be challenging to install because they require a completely dry surface. However, they are one of the most commonly-constructed culverts due to their numerous advantages:

• They have a simple construction and a very rigid frame
• They are appropriate for non-perennial streams where the soil is weak
• They exert reduced soil pressure
• They do not require separate foundations

Arch culvert

Arch culverts can be made using a range of materials, including reinforced concrete, concrete, stone masonry, metal, and others. They can be constructed so they don’t disturb the current of water and are perfect for areas where there is no need for water diversion. Other benefits include:

• Cost-efficiency
• Fast construction
• Exceptional hydraulic efficiency
• Striking aesthetics

Bridge culvert

Bridge culverts have two purposes – they are both bridges and culverts. They generally feature a rectangular shape and go over canals and rivers. These multi-purpose culverts have a foundation below the ground level and they feature a pavement surface. They are a good option for the following reasons:

• Strong and durable
• Allow for the flow of traffic
• Very strong foundation

Metal box culvert

Finally, metal box culverts serve as an economical option for a bridge. They are made using either standard or deep-corrugated structural plate. Their benefits include:

• Durability
• Short construction time
• Easy installation
• Longevity
