Cold-rolled (CR / DKP) square tube to EN 10305-5 is ERW-welded from typically DC01 strip. Compared with structural EN 10219 box, it has a smoother surface, tighter dimensional tolerances, and thinner walls starting from about 0.70 mm — made for furniture, automotive, white goods, and light fabrication rather than primary structural frames.
Do not substitute CR tube for S235/S355 hollow sections in load-bearing steelwork. Use it where appearance, paintability, and fit in jigs or automated assembly matter. Sizes start from about 10×10 mm; standard length is 6 m.
