S235 steel — about the material
S235 is a non-alloy structural steel used for structural components, brackets and general-purpose parts. The hot-rolled bar surface is matt and may have mill scale. Prepare it appropriately before welding, painting or other finishing. The full grade variant, delivery condition and specific batch properties are defined by delivery documentation.

Preparation and cutting
Cutting into ordered sections can be agreed before purchase. State length, number of sections and required cutting tolerance in your enquiry.

Section dimensions
a denotes the side of the square cross-section and L the length of one bar. On this card a = 18 mm and L = 2500 mm. The sales unit contains 1 separate sections of this length. The end view shows a solid square and the side view the bar's length and height. The diagram is illustrative and not drawn to scale.

Standards and tolerances
Dimensions and shape tolerances of hot-rolled square bars are specified by PN-EN 10059:2005, adopting EN 10059:2003. It replaced PN-EN 10059:2004. The former DIN 1014-1:1978-07 and DIN 1014-2:1978-07 were replaced by DIN EN 10059:2004-02.
For the offered 18 × 18 mm cross-section, manufacture to EN 10059 is confirmed: each side has deviations ±0,500 mm, giving a permitted range 17,500–18,500 mm. Agree the length tolerance of the ordered section before purchase.
The reference for technical delivery conditions of non-alloy structural steel S235 is PN-EN 10025-2:2019-11. The full grade variant, delivery condition and compliance of the specific batch are defined by delivery documentation.
Sales unit mass
The theoretical mass follows from nominal dimensions and steel density 7850 kg/m³. For dimensions in millimetres: m = a × a × L × 7,85 × 10⁻⁶ × n. On this card a = 18 mm, L = 2500 mm and n = 1. The mass of the entire sales unit is approx. 6,359 kg. For packs, the mass of all pieces is calculated first, then rounded to 0,001 kg. Mass excludes packaging and is not a weighing result.
