ERW steel box is so called because of the electronic resistance welding method employed in its manufacture, which uses a combination of heat and pressure resulting in a very consistent and strong forged weld seam.
However it is employed, mild steel square ERW box offers a terrific level of performance and reliability, and it is also favoured as a very ‘green’ option as it is widely recycled.
Square tube is a popular choice for the construction of space frames and strong yet lightweight structures such as kit car chassis’. Mild steel square box benefits from the strength and low weight of this structure and combines the formability and versatility that the lower carbon content of mild steel affords. This results in a square tube which is extremely easy to work with and one which can be cut, drilled and welded to suit any requirement.
Our square ERW box is delivered pre-cut to your desired dimensions, simply input the size of mild steel tube you require into our price calculator along with the number of lengths you require.
Please note: Our current machines operate to a tolerance of +/- 2mm. Please enter your desired dimensions below to the nearest whole mm.
