Steel square tubes 30 x 30 x 1,5 mm
Product information
Steel square tubes bright cold-drawn – E220+CR2 / E235+CR1 (S2) according to EN 10305-5
These bright cold-drawn steel square tubes are manufactured from precision steel E220+CR2 or E235+CR1 in accordance with EN 10305-5. They are cold-formed and cold-calibrated precision hollow sections with a square cross-section and surface condition S2 (bright). The cold-drawing process ensures tight dimensional tolerances, high straightness and improved surface quality.
Main features
- Material: E220+CR2 / E235+CR1 according to EN 10305-5
- Manufacturing: Cold-drawn and cold-calibrated
- Profile shape: Square hollow section
- Surface: Bright (surface condition S2)
- Dimensional accuracy: Precision tube with tight tolerances
Note: Due to the manufacturing process, slight drawing marks, minor scratches or transport-related surface characteristics may occur. These are process-related and do not constitute a quality defect provided EN 10305-5 requirements are met. Saw-cut edges are unfinished and not deburred.
Material properties:
- high dimensional accuracy due to cold-drawing process
- uniform wall thickness distribution
- good forming and welding properties
- fine bright metallic surface (S2)
Technical specifications
- Standard: EN 10305-5
- Material grade: E220+CR2 / E235+CR1
- Surface condition: S2 bright
- Tolerances: according to EN 10305-5
- Surface: Bright cold-drawn
- Lengths: Standard lengths or custom cut
- Dimensions: Depending on selected profile size
Dimensional, shape and straightness tolerances comply with EN 10305-5. The bright surface is usually lightly oiled or preserved and may show optical changes due to storage or transport. Without additional surface treatment, no permanent corrosion protection is provided; appropriate further processing or storage is recommended.
Applications
- Precision and mechanical engineering
- Fixture and frame constructions
- Technical components with high dimensional requirements
- Mechanical processing and construction engineering
Delivery is made as cold-drawn precision hollow sections in accordance with EN 10305-5. Production-related deviations within permissible standard tolerances are possible.

Stabiles Stahlprofil mit sauberem Zuschnitt
Das Stahl Vierkantrohr schwarz/roh ist sehr stabil und wurde exakt nach Maß geliefert. Die Schnittkanten waren sauber, die Abmessungen haben gepasst und das Material macht einen soliden Eindruck. Für Werkstatt, Stahlbau oder einfache Konstruktionen ist das Vierkantrohr sehr gut geeignet. Bestellung und Lieferung liefen ebenfalls problemlos.
