Product Description

Mild Steel Tube Description

As the name suggests, low-carbon steel pipes are steel pipes with mild content. Generally speaking, low-carbon steel pipes are different from seamless carbon steel pipes. Low-carbon steel pipes refer to steel pipes with a carbon content of less than 0.3%.Seamless mild steel tube belong to one of them.In addition to general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, low carbon steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, and stainless steel thin-walled steel pipes. , Shaped steel pipe.


Low carbon steel is also called mild steel because of its low strength, low hardness and softness. It includes most ordinary carbon structural steels and some high-quality carbon structural steels, most of which are used for engineering structural parts without heat treatment, and some are used for mechanical parts requiring wear resistance after carburizing and other heat treatments. Low carbon steel with carbon content from 0.10% to 0.30% is easy to accept various such as forging, welding and cutting, and is often used in chains, rivets, bolts, shafts, etc.

Scope of Application

Mild steel tube is an essential tool in many areas of construction including industrial applications, transport projects and even architectural jobs.
According to the amount of carbon element, iron is usually divided into high carbon steel, medium carbon steel and low carbon steel. The higher the carbon content, the harder the iron, the poorer the toughness, and the easier it is to break. Low-carbon steel is generally rolled into angle steel, channel steel, I-beam, steel pipe, steel strip or steel plate, and is used to make various building components, containers, boxes, furnaces and agricultural machinery. At the same time, low carbon steel pipe.Also an important tool in many fields of construction, including industrial applications, transportation projects and even construction work.

FAQ

Q1: What types of steel products does your company primarily manufacture and supply?
A: We are a direct manufacturer specializing in carbon steel, hot-dip galvanized steel, PPGI (pre-painted galvanized iron), and stainless steel (grades 201, 304, and 316) in the form of sheets, coils, pipes, and various structural profiles, along with complementary steel structural components. Our products serve a wide range of industries, including infrastructure, photovoltaics, machinery manufacturing, chemicals, and new energy.

 

Q2: Do you support customization regarding material grades, thicknesses, and dimensions?
A: Customization is available across our entire product range. For carbon steel, galvanized steel, and stainless steel, we can adjust thickness, width, and cut-to-length dimensions according to GB, ASTM, or EN standards. Various profiles can be cut and bent based on customer drawings, and special steel grades can be produced through customized scheduling.

 

Q3: What is the difference between galvanized steel and color-coated (PPGI) steel, and how should I choose for my project?
A: Hot-dip galvanized steel features a pure zinc anti-rust layer; it is cost-effective and impact-resistant, making it ideal for mounting brackets, guardrails, and load-bearing factory structures (and it can be painted over). PPGI color-coated steel uses a galvanized base, offering both rust protection and aesthetic appeal with a wide range of colors; it is commonly used for factory roofing, wall cladding, and energy storage equipment casings. We recommend thicker galvanized coatings for projects in rainy coastal areas, color-coated sheets for outdoor projects requiring visual appeal, and weather-resistant fluorocarbon (PVDF) coatings for high-temperature desert environments.

 

Q4: Does the factory keep stock on hand, and what is the minimum order quantity (MOQ)?
A: We operate our own standardized, zoned warehouse with a capacity of over 10,000 tons, maintaining ample stock of carbon steel, galvanized steel, and stainless steel. The MOQ for standard specifications is 1 ton, though we also accept sample orders as small as a few dozen kilograms. There is no upper limit for large-scale projects, and we support mixed-load shipments combining different steel products in a single container.

 

Q5: What are the lead times for stock items versus customized products?
A: Standard stock items take 3–7 days for processing, packaging, and container loading. Simple cutting and bending orders take 7–10 days. Orders requiring mold creation or special steel customization take 15–30 days; exact delivery dates are confirmed based on the customer's specific order specifications.
