S235 steel — material overview
S235 is a non-alloy structural steel used for structural components and general-purpose parts. Drawing provides more accurate dimensions and a smoother surface than a typical hot-rolled product. Properties of the specific batch and the detailed grade are determined by the material documentation.

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

Section dimensions
The symbol a denotes flat bar width, t its thickness and L its length. On this card a = 45 mm, t = 25 mm, L = 2000 mm. The end view shows the solid rectangular cross-section, and the side view shows length and thickness. The diagram is illustrative and not drawn to scale.

Standards and tolerances
The current reference for drawn bright steel products is PN-EN ISO 683-7:2025-04, adopting EN ISO 683-7:2024 and ISO 683-7:2023. It replaced PN-EN 10277:2018-09. Conformity of the specific batch is determined by the delivery documentation.
The historical DIN 174:1969-06 for drawn flat bars was withdrawn and replaced by DIN EN 10278:1999-12. The DIN EN 10278:2024-01 edition has a revised scope excluding non-alloy and alloy steels covered by EN 10277. For S235, we therefore indicate the current reference PN-EN ISO 683-7.
For width a = 45 mm in class h11, the upper deviation is 0 mm and the lower deviation −0,160 mm. Permissible width: 44,840–45,000 mm. Thickness t = 25 mm is class h11: +0 / −0,130 mm, range 24,870–25,000 mm. Requirements for length, straightness and corners are agreed separately.
Mass of the sales unit
The theoretical mass follows from nominal dimensions and a steel density of 7850 kg/m³. For dimensions in millimetres, m = a × t × L × 7,85 × 10⁻⁶ × n. One 45 × 25 × 2000 mm flat bar has a theoretical mass of approx. 17,663 kg after rounding to 0,001 kg. Number of pieces: 1. Mass is calculated before rounding. It excludes packaging and is not a weighing result.
Product family — drawn S235 flat bars
In the table, select width a and then cross-section a × t. The links lead to S235 offers for that cross-section. Check the available lengths and sales unit on the selected card. Identified lengths for 45 × 25 mm are listed above.
How to order
Buying 1 unit means one 45 × 25 × 2000 mm flat bar. Buying 2 units means two separate flat bars, each 2000 mm long. Select another length from the available 45 × 25 mm offers.
Order fulfilment
Dispatch of an in-stock product: within 5 days. Delivery time depends on the carrier. If out of stock, availability must be confirmed.
