Electric resistance welded (ERW) tubes are cold formed and can be made in huge lengths with uniform diameters and wall thicknesses along the entire length. To make the tube, a plate of steel is pulled through rollers to force the material into a cylinder. When the edges of the steel meet, an electrical charge is used to heat them and create a weld, forming the tube. This weld is then usually ground down to leave a smooth finish although some providers may leave it to the consumer to do this.
ERW tubes remain one of the most popular types of tubular products on the market because they are cost effective and can be made in a wide range of dimensions. Cold formed tubing is always more affordable because there are much lower costs associated with manufacturing it. These savings can then be passed on to clients.
The tubing industry has changed greatly over the years as customers demanded more and more products in non-standard shapes and sizes. You can now find ERW tubes in an array of different shapes, including round, oval, square, rectangular and even hexagonal. They can also be designed to have a different shape inside the tube. You could create a round pipe with a hexagonal interior if you wish, or all kinds of other combinations. With all of these specifications it is important to keep the wall thickness in mind.
We are a skilled ERW steel tube supplier in the West Midlands, producing tubes in a wide range of standard and non-standard sizes. In the first instance we have large stocks ready to cut to size so we can satisfy customer orders very quickly. This strategy also means we can offer excellent prices as the lead time is short and there is no need for expensive tooling. Non-standard tubes take a little longer to make but we are highly efficient and get tubing made in the shortest space of time possible.
Alongside great prices we also provide quality assurances on all of our products. We test every length of tube rigorously to make sure it meets out standards and is fit for use. The attention to detail is always appreciated by our clients.
