GI Pipe: Introduction, Features, and Application

GI pipes and MS pipes are zinc protected and low carbon pipes, respectively. Both pipes are extremely useful, and a number of industries use them. The best part about the two pipe variants is that they both are quite affordable. A GI and MS pipe is also known as GI tube and an MS tube. To make sure you are buying a quality GI or MS pipe, you must choose a reliable and well-known distributor such as the Sino Rise Industry.

After discussing the features and application areas of these two pipe types, we will also share some tips on how you can find a reliable distributor around.

Introduction to GI Tube

GI stands for ‘galvanized iron’. The GI pipes have significant importance among other types of pipes that different industries and applications use. Galvanization is the process of applying a Zinc coating to steel or iron.

Galvanization is done to improve the ability of iron and steel to guard against rust and/or corrosion. Pure iron contains 0% carbon and is extremely ductile. Zinc metal, on the other hand, is extremely long-lasting and thus it magically improves the lifespan of steel and iron, when manufacturers apply it on them.

Various structural applications also use Steel and GI iron pipes. They come with a zinc layer that ensures 100% rust protection. These tubes are available in many shapes and sizes to match the diverse needs of different customers. Now, let’s go through the features and application areas of the GI tubes.

GI Pipes (Tubes) Main Features

Here are some of the most important GI tube features that you must know:

  • Extremely durable
  • Higher longevity
  • Rigorous fabrication
  • Easier welding
  • Anti-rust coating
  • Greater corrosion resistance
  • Easy to cut
  • Easy to bend
  • Ease of threading

The GI pipes have a super finish and they follow all international standards of quality.

GI Pipes: Application Areas

There are many application areas where GI tubes are used. Here are some of them:

  • Main water supply
  • Wastewater transmission
  • Firefighting equipment
  • Sewerage lines
  • Gas and water line
  • Air duct
  • Compressed airline
  • Chemical transportation

The GI tubes have an advantage over other types of pipes for many good reasons including cost-efficient piping solution, low maintenance cost, and highest quality standards. All such benefits make this type of pipe best for large construction projects.

About MS (Mild Steel) Tubes

Carbon is present very densely in iron and it is being used in the manufacturing of pipes and other materials that are hard in nature. The presence of carbon steel in MS pipes is only 0.18% or even less. The low carbon availability in the mild steel tubes makes them less hard and easy-to-use.

Manufacturers produce such pipes from mild steel that has a low amount of carbon present. It is possible to easily convert them into different shapes and sizes for different purposes, such as pipelining and tubing.

Generally, these tubes are best used for drinking water supply, HVAC, plumbing, and firefighting. Apart from that, they are also effective for different industrial and engineering applications. The mild steel pipes are layered with varnish, paints, or other such metals. This helps the tube in protection against rusting and makes them highly durable. The coating of paint or varnish also helps the pipework well under critical situations.

MS Pipes Main Features

Although there are many, below are some of the major features of mild steel pipes or tubes:

  • Mild steel tubes or pipes come with greater ductile strength
  • These pipes adhere to the ASTM specifications
  • These tubes are enormously stronger
  • Low carbon presence
  • Easy to weld
  • Their fabrication is very easy
  • Very affordable
  • Highly durable

When compared to many other metals, the cost of MS tubes is very low, which makes them a very affordable option. A high-quality mild steel pipe can last as long as 100+ years. So, they are not only cheap in rate, but are also long-lasting.

MS Pipes: Application Areas

You can use mild steel pipes for a number of purposes. Here are some of the major application areas of these pipes:

  • Mechanical applications
  • Structural applications
  • Domestic applications
  • General engineering
  • Water steel tubes
  • Fencing
  • Designing of bus bodies

The structural uses of MS tubes include a shed, railing, doors, tents, stairs, and scaffolding. Industries, use them for barricading, trolleys, poles, machinery, and tools. The Automobile industry also uses them for manufacturing automobile parts, tools, chassis, and steering. Domestic uses include tents, stairs, decoration, fencing, railings, and doors. These pipes are also used in furniture applications, such as storage systems, racks, tables, and chairs.

The above-discussed application areas and features of the mild steel tubes reflect that they are extremely useful pipes for several industries.

Choosing the Right GI and MS Pipes Dealer

Choosing the right pipes dealer is important to ensure a successful project. Before you buy an MS or GI tube, make sure the seller is a trusted dealer. The dealer must be dealing in the business of structural steel and must have a valid license.

There is no offense in asking the dealer to show their license. Alternatively, you can also go through the reviews of the dealer’s old customers. This will also give you an idea about their credibility and quality standards.

Below are some effective tips to ensure that you choose the right manufacturer.


It is imperative for the manufacturer to have massive experience. With the right kind of experience, they will be able to deliver high-quality products within the desired time frame.


Of course, budget is important. However, finding a cheap alternative would not ensure the quality of the product. So, make sure that there is a balance between the price and product quality. At Sino Rise, we promise to deliver the best quality possible while making sure that the product falls within the client’s budget.


Every industry has some set standards. In order to achieve these standards, the manufacturers need certain certifications. The manufacturer that you choose should have all the required certification as that would guarantee that the product would be of the finest quality.

Customer Service

If a company does not have good customer service, it means that they are really not concerned with their clients. Since the first priority of any manufacturer should be client satisfaction. Thus, ensure that the manufacturers that you choose should have highly responsive customer service.
