Rectangular tubes are formed from coils and then ran through a series of dies. They are are welded from the inside to form their shape. Rectangular tubes are generally used for maintenance and structural purposes.
Rectangular tubes are formed from coils and then ran through a series of dies. They are are welded from the inside to form their shape. Rectangular tubes are generally used for maintenance and structural purposes.
Rectangular steel tube comes in different sizes, specifications and wall thicknesses.
Its uniformity makes it predictable to use and visually appealing. It has a high weight-to-strength ratio.
ASTM A500 Gr.B galvanized rectangular steel pipe
It’s easy to bend, and because square steel tubing is inexpensive, it’s cost-effective- even for large projects.
We are manufacturing and exporting Rectangular Hollow Sections, Rectangular Hollow Steel Sections and Rectangular Hollow Section Tubes as per customer’s requirement with anti rust oil coating from inside & outside of the tubes to ensure safe delivery to end customers.
Rectangular Tube is commonly available in Aluminium, Stainless Steel, Black Steel and Bright Steel. It can be purchased at any Metal Supermarkets location. It can be cut to your exact specifications.
Stainless rectangular tube
Stainless steel rectangular tube is referred to as tube steel or structural tubing. Rectangular tubing is used for structural purposes and can be purchased in many different types of steel and alloys.
Specialising in Steel, Cut to Length, Round, Square, Hollow, Rectangular, Rectangular Hollow Sections, RHS
A wide range of dimensions, when combined with the appropriate steel grade, ensure that the functionality and cost-efficiency of your structure can be optimised.
Application:
Furniture industries & domestic applications, bus body, fencing etc. Sizes other than mentioned above can also be produced upon specific requirements.
Note: Pre-galvanized square / rectangular hollow section with OD 19mm-70mm and thickness 1mm-2.3mm are also available.
Hot rolled rectangular steel tube is ideal for structural applications, general fabrication, repairs and manufacturing. Its box-shape design allows for increased strength and rigidity over other shapes of hot rolled steel. Hot rolled rectangular steel tube is easy to cut, weld, form and machine.
Steel rectangular tube is a versatile solution for:

Pipeline coating is the most consistent and successful solution for protecting ERW pipes from corrosion, from moisture, other harmful chemicals.
Anti-corrosion steel pipe is processed through the preservation process, which can effectively prevent or slow down the process in the transport and use of chemical or electrochemical corrosion reaction of steel pipe.
Therefore pipe anti-corrosion layer is an important barrier to prevent soil erosion. A well-known foreign scholar put forward” 3PE france protective layer”, so far, anti-corrosion methods is widely used.
Coated pipes offer high resistance to corrosion on pipes and provide many benefits such as:
1. Increased Flow Capacity – A coating on pipes helps provide a smoother surface thus improving gas and liquid flow within pipes.
2. Reduced Cost – The pipeline coating increases the pipes durability so they can be deployed with minimum maintenance cost even in the harshest environments.
3. Lower energy usage – Various studies have shown that pipelines that are internally coated use less energy for pumping and compression of products through pipes. This helps in increased saving over time.
4. Clean delivery of products – The inhibitors used for the protection products can also be minimized by the use of coated pipes for delivery of products.
Thus, coating of pipelines can help you in reducing your maintenance cost and at the same time providing a corrosion free reliable protection.

Pipe Coating Products
Three Layer Polyethylene (3LPE)
To improve anticorrosion performance and adhesion, an additional layer of epoxy primer is sprayed onto pipe surfaces prior to the adhesive layer and Polyethylene top layer application. Three Layer Polyethylene is suitable for service temperatures from 60°C to 80°C (85°C peaks). Typical coating thickness is from 1-2 mm to 3-5 mm.
Three Layer Polypropylene (3LPP)
If a wider service temperature range and high stiffness is required, adhesive and top layers, applied over primer layer, are based on polypropylene instead of polyethylene. Three Layer Polypropylene is suitable for service temperatures up to 135 °C (140°C peaks). Typical coating thickness is from 1-2 mm to 3-5 mm.
Three Layer Polypropylene and Polyethylene
Three Layer applications involve a thermoplastic coating applied to steel pipelines as a form of anticorrosion protection. This mechanical resistance is appropriate when the risk of particularly severe coating damages exist. The Three Layer process involved several steps. First, the pipe surface is blast cleaned to remove any external residue from the mill or storage. It is then heated and sprayed with a Fusion Bond Epoxy (FBE) primer followed by the application of an adhesive copolymer and polyolefin polymers that are wrap extruded, one over the other.

Advantage of ERW pipe
The alloy content of the coil is often lower than similar grades of steel plate, improving the weldability of the spiral welded pipe. Due to the rolling direction of spiral welded pipe coil is not perpendicular to the pipe axis direction, the crack resistance of the spiral welded pipe materials.
